        N/A



Version 3.1.2
(13 January 2014, from /trunk)
http://svn.gna.org/svn/relax/tags/3.1.2

    Features:
        N/A


    Changes:
        * The average_intensity() dispersion function now accepts the offset argument.  This is for better support of combined offset and spin-lock varied R1rho-type data.  The argument is then passed into the find_intensity_keys() function.
        * Improved the DPL94 dispersion model description in the manual.
        * Copied a Sparky peak list to be modified to be a Sparky file without intensity column.
        * Modified the Sparky file to have no columns with intensity values.
        * Implemented to read spins from a SPARKY list, when no intensity column is present.  Addition to Support Request #3044, (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Created the Relax_disp.test_bug_21460_disp_cluster_fail system test.  This is to catch bug #21460 (https://gna.org/bugs/?21460) reported by Min-Kyu Cho.  The save file added to the repository consists solely of the data for the first residue.
        * Speed ups for the Relax_disp.test_bug_21460_disp_cluster_fail system test.  The optimisation precision is not important for demonstrating this bug.
        * Updated the main copyright notice for 2014.
        * Fix for the main copyright notice.
        * Updated the copyright notice visible to the user to 2014.
        * Updated the copyright for the relax GUI splash screen for 2014.
        * Improvement for the relax test suite printout with the --time command line argument flag.  The tests printed out now have the package and module names removed, so that one the test name remains.  This removes a large amount of text, simplifying the printout.


    Bugfixes:
        * Partial fix for bug #21338 (https://gna.org/bugs/?21338) - the bad sRGB profile in some PNGs.  This is only partial as some files are still to be converted (the original Bruker logo, and the 16x16, 22x22 and 32x32 sized Bruker icons).
        * Fix for bug #21460, the failure of relaxation dispersion due to incorrect spectrometer information.  This is the bug https://gna.org/bugs/?21460, reported by Min-Kyu Cho.  There was only one place in the dispersion analysis which failed due to a spectrometer frequency not containing any relaxation data - in the insignificance testing in the auto-analysis.
        * Loosened the chi2 check in the Relax_disp.test_korzhnev_2005_15n_mq_data system test.  This is to allow the test to pass on a 32-bit Linux (Mageia 1) test system.



Version 3.1.1
(10 December 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/3.1.1

    Features:
        * Support for reading 3D structures of organic molecules from Gaussian log files using the new structure.read_gaussian user function.
        * Addition of the lib.periodic_table module for storing information about the periodic table.
        * Addition of the lib.nmr module for basic NMR related functions.  It currently has functions for converting between ppm, Hz, and rad.s^-1 units.
        * Many improvements to the relaxation dispersion chapter of the user manual.
        * The 'NS MMQ 3-site linear' numeric model - the model for 3-site exchange using 3D magnetisation vectors linearised with kAC = kCA = 0 with the parameters {R20, ..., pA, pB, dw_AB, dw_BC, dwH_AB, dwH_BC, kex_AB, kex_BC}.
        * The 'NS MMQ 3-site' numeric model - the model for 3-site exchange using 3D magnetisation vectors with the parameters {R20, ..., pA, pB, dw_AB, dw_BC, dwH_AB, dwH_BC, kex_AB, kex_BC, kex_AC}.
        * The 'NS R1rho 3-site linear' numeric model - the model for 3-site exchange using 3D magnetisation vectors linearised with kAC = kCA = 0 with the parameters {R1rho', ..., pA, pB, dw_AB, dw_BC, kex_AB, kex_BC}.
        * The 'NS R1rho 3-site' numeric model - the model for 3-site exchange using 3D magnetisation vectors with the parameters {R1rho', ..., pA, pB, dw_AB, dw_BC, kex_AB, kex_BC, kex_AC}.
        * More model nesting in the relaxation dispersion auto-analysis ('CR72' and 'MMQ CR72', 'LM63' and 'LM63 3-site').
        * Large speed up of the 'TP02' and 'NS R1rho 2-site' dispersion models by minimising repetitive calculations.
        * Support for the loading of spins directly from peak lists.
        * Support for the reading of peak intensities from NMRPipe seriesTab formatted files (*.ser).


    Changes:
        * Small improvement for the devel_scripts/log_converter.py script for detecting commit boundaries.
        * Added many small details to the release checklist document.  This is for the formatting and editing of the CHANGES file, which is used for the release announcements.  Some additional details about the API documentation at http://www.nmr-relax.com/api have been added too.
        * Added sectioning printouts for the relaxation dispersion auto-analysis.  This simply tells the user which part of the protocol is currently being performed.
        * Setup for testing the sample_scripts/relax_disp/R1rho_analysis.py sample script.  The script was copied into the test_suite/shared_data/dispersion/r1rho_off_res_tp02/ data directory where it will be tested on real data.  The 'fake_sequence.in' and 'unresolved' files have been created to allow the script to run.  And the script itself has been heavily debugged.
        * All of the relaxation dispersion auto-analysis options are now exposed by the sample scripts.  This included the pre_run_dir argument for specifying a directory of results from a non-clustered analysis and the flag for running MC simulations for all models.
        * Added the DATA_PATH variable to the cpmg_analysis.py dispersion sample script.  This allows the user to more easily specify a different directory for the files.
        * Docstring improvement for the test_suite/shared_data/dispersion/r1rho_off_res_tp02/R1rho_analysis.py script.
        * Synchronised the test_suite/shared_data/dispersion/Hansen/relax_disp.py with the sample script.  This script now matches very closely with the sample_scripts/relax_disp/cpmg_analysis.py sample script.  This is for sample script debugging purposes.
        * Created a base data pipe for Flemming Hansen's truncated CPMG data for testing out missing data.  The :4 spin is missing just a few data points, whereas the :71 spin is missing all 800 MHz data.
        * Created the Relax_disp.test_hansen_cpmg_data_missing_auto_analysis system test.  This is used to demonstrate a failure in the 'R2eff' model when some data is missing.
        * Expansion and fixes for the Relax_disp.test_hansen_cpmg_data_missing_auto_analysis system test.  The parameters for spin :4 are now being checked, and all the checks updated for the changed data.  The parameter values are slightly different as data is now missing and because only 3 spins are used for the error analysis whereas in all other Hansen CPMG data sets the more accurate errors are from all spins.
        * The lib.dispersion.cr72.r2eff_CR72() function is now more robust.  Values less than 1.0 are now caught to avoid passing it into the numpy.arccosh() function.  This avoids many warning messages on Mac OS X.
        * Added a Gaussian DFT optimisation log file to the shared data directories.  This will be used to test the reading of structural data from Gaussian files.
        * Modified the Relax_disp.test_hansen_cpmg_data_missing_auto_analysis system test to catch another failure.  This is the failure of all numeric models when all data from one magnetic field strength is missing for a spin.
        * Created data for a 'NS MMQ 3-site (branched)' model using cpmg_fit from Dmitry Korzhnev.
        * The relax_disp.r2eff_read_spin user function now really strips comments and empty lines from the file.
        * A big change to the usage of the relax_disp.r2eff_read_spin user function.  Now the nu_CPMG frequency or the spin-lock field strength must be set prior to calling this user function.  This allows for more flexibility as often the experiment IDs and frequency values in the files do not match to the same number of decimal places.  The frequency is no longer read from the file but must be preset.
        * Created a relax script for back calculating R2eff values for the same parameters as cpmg_fit.  This is for the 'NS MMQ 3-site (branched)' CPMG dispersion model.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_test_suite.
        * Created the Relax_disp.test_ns_mmq_3site_branched system test.  This is for the 'NS MMQ 3-site (branched)' CPMG dispersion model.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_test_suite.
        * Added the 'NS MMQ 3-site' models to the dispersion variables.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site (linear)' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Adding_the_model_to_the_list.
        * Added another Gaussian log file of strychnine, this time with DFT structure optimisation.  The file is bzip2 compressed to save space.
        * Created the Structure.test_read_gaussian_strychnine system test.  This will be used for implementing and testing the structure.read_gaussian user function.
        * Created the lib.periodic_table module for storing information about the periodic table.  This is via the periodic_table object which will have different methods for obtaining different information about an element.
        * Implemented the structure.read_gaussian user function.  This will read the final structural data out of a Gaussian log file.
        * Improved the checking of the Structure.test_read_gaussian_strychnine system test.  This now checks all the atomic information loaded.
        * Simple fix for the Relax_disp.test_korzhnev_2005_*_data system tests.  The CPMG frequencies are now being set up in the setup_korzhnev_2005_data() method.
        * Added support for the 'NS MMQ 3-site' model parameters to the lib.text.gui module.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site (linear)' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added the 'NS MMQ 3-site' models to the relax_disp.select_model user function frontend.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site (linear)' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_front_end.
        * Added support for the 'NS MMQ 3-site' models to the relax_disp.select_model user function back end.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site (linear)' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_back_end.
        * Added support for the new 3-site exchange dispersion parameters.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site (linear)' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Adding_support_for_the_parameters.
        * Removed the brackets from the 'NS MMQ 3-site (linear)' dispersion model name.
        * Renamed the Relax_disp.test_ns_mmq_3site_branched system test to Relax_disp.test_ns_mmq_3site.
        * Fixes for the loop_parameters() dispersion function for the new 'NS MMQ 3-site' model parameters.  The new parameters were not being handled by this function.
        * Created the target functions for the 'NS MMQ 3-site' models.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site (linear)' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_target_function.
        * Added the R2eff calculating functions for the 'NS MMQ 3-site' models to the relax library.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site linear' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_library.
        * Added the 'NS MMQ 3-site' models to the dispersion auto-analysis.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site linear' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_auto-analysis.
        * Added the 'NS MMQ 3-site' models to the GUI model list.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site linear' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_GUI.
        * Updated the 'MMQ 2-site' model description in the manual.  The R2_DQ = R2_ZQ = R20 assumption is now explained.
        * Added the 'NS MMQ 3-site' models to the relax user manual.  This is for the 'NS MMQ 3-site' and 'NS MMQ 3-site linear' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_manual.
        * Completed the 'MMQ 2-site' documentation in the manual.  The equations for the numeric evolution of SQ, ZQ and DQ data was missing.
        * Huge speed ups of the relaxation dispersion analysis.  This is due to the removal of huge inefficiencies in the loop_point(), return_cpmg_frqs() and return_spin_lock_nu1() functions of the specific_analysis.relax_disp.disp_data module.  Two new functions return_cpmg_frqs_single() and return_spin_lock_nu1_single() have been introduces to pull out the nu_CPMG and spin-lock field strengths for a given experiment and spectrometer frequency.  This avoids calling the loop_exp() and loop_frq() functions from within loop_point() which itself is often called inside a loop_exp() and loop_frq() sequence.
        * Added the results of cpmg_fit minimisation of the cpmg_fit synthetic data for the 'NS MMQ 3-site' model.
        * Fixes for the 'NS MMQ 3-site' dispersion models - the evolution matrix is now correctly constructed.
        * Another fix for the 'NS MMQ 3-site' dispersion models.  The creation of the Z-matrix had a copy and paste error in that the heteronuclear chemical shift sign was negated when it should be positive.  This was only in one of the two chemical shift numbers.
        * Loosened the chi-squared check of the Relax_disp.test_ns_mmq_3site system test to allow it to pass.
        * Speed up of the Relax_disp.test_ns_mmq_3site system test.  The relax_disp.plot_disp_curves user function call is now skipped as it takes too long.
        * Renamed the 'ns_mmq_3site_branched' dispersion test data directory to 'ns_mmq_3site'.
        * Created the Relax_disp.test_ns_mmq_3site_linear system test and modified Relax_disp.test_ns_mmq_3site.  The Relax_disp.test_ns_mmq_3site_linear system test uses the old data from the directory test_suite/shared_data/dispersion/ns_mmq_3site/, as this had kAC = 0, now copied into the ns_mmq_3site_linear/ directory.  This system test uses the 'NS MMQ 3-site linear' model.  The base data generated by cpmg_fit for the Relax_disp.test_ns_mmq_3site system test was modified so that kAC is no longer 0, but set to 1000.  This should properly test the 'NS MMQ 3-site' model.
        * Renamed the 'MMQ 2-site' model to 'NS MMQ 2-site'.  This is so that the name matches those of the 'NS MMQ 3-site linear' and 'NS MMQ 3-site' models.
        * Renamed all remaining instances of 'MMQ 2-site' to 'NS MMQ 2-site'.  This is simply changing variable, method and module names.
        * Removed the 'MMQ 3-site branched' and 'MMQ 3-site linear' models from the to do list in the manual.  These two dispersion models are now implemented.
        * Renamed the 'MQ CR72' dispersion model to 'MMQ CR72'.  The model is designed by Korzhnev et al., 2004 for proton-heteronuclear SQ, ZQ, DQ, and MQ data (or MMQ data), so the change is logical as the model is not just for MQ data.
        * Clean up of the 'NS R1rho 3-site' model names in the manual.  The word 'branched' has been removed and the notation now matches the 'NS MMQ 3-site' models.
        * Clean up of the parameter lists in the dispersion model table of the manual.
        * The pC parameter constraints are now implemented for the 3-site dispersion models.  The new constraints are 0 <= pC <= pB.
        * Editing of the introduction section of the dispersion chapter of the manual.
        * Added the 'NS MMQ 3-site' parameters to the optimisation section of the dispersion chapter of the manual.
        * Added some R1rho data from Dmitry Korzhnev's Fyn SH3 domain.  This originates from the cpmg_fit software and is published data.
        * Small fix for the documentation of the relax_disp.r2eff_read* user functions.  This is for both relax_disp.r2eff_read and relax_disp.r2eff_read_spin.
        * Created the new lib.nmr relax library module.  This currently has a few simple functions for converting between ppm units and Hertz or rad/s units.
        * The relax_disp.spin_lock_offset user function now uses the lib.nmr module.  This is for converting between ppm and rad/s units.
        * The relax_disp.r2eff_read_spin user function now can handle offset data in the file.  If the new offset_col argument is set and disp_point_col is not, then the file being read can contain the spin-lock offset information rather than the spin-lock field strength values.  This is only for R1rho-type data.
        * Implemented GUI test which caches the bug #21076 (https://gna.org/bugs/?21076) - when loading a multi-spectra NMRPipe seriesTab file through the GUI, several Error messages occur.
        * Large redesign of the R2eff/R1rho data structures.  The five indices {Ei, Si, Mi, Oi, Di} for the experiment type, the spins of the cluster, the magnetic field strengths, the pulse offsets, and the dispersion points (nu_CPMG or nu1) respectively are now much better defined.  The Oi dimension is new and allows for support of R1rho-type data whereby both different offsets and different spin-lock field strengths have been collected.  Previously only one or the other was supported, but not both together.  The offset information is now included as part of the spin R2eff/R1rho key, even if not set.  To support this, the specific_analyses.relax_disp.disp_data module now has the new functions loop_exp_frq_offset(), loop_exp_frq_offset_point(), loop_exp_frq_offset_point_time(), loop_frq_offset(), loop_frq_offset_point_key(), loop_offset(), and loop_offset_point().  All of the {Ei, Si, Mi, Oi, Di} dispersion indices throughout the source tree have been changed to ei, si, mi,oi, and di respectively.  And the time index ti has also been introduced.  These changes hugely simplify the code.
        * The relax_disp.plot_disp_curves user function can now support 150 sets per Grace graph.
        * The relax_disp.plot_disp_curves user function can now support 3000 sets per Grace graph.

        * Added some more files for the Fyn SH3 R1rho test data.  This includes the cpmg_fit input and output files, R1 data files for relax as R1 cannot optimised yet, and a relax script.
        * Added system test for reading spins from a Sparky list.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.

        * Fix for system test.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Extended reading of Sparky files to include residue names.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Expanded system test and made it pass for user function spectrum.read_spins.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Updated the GUI test to check for first ID in list.  Fix for bug #21076, (https://gna.org/bugs/?21076) - When loading a multi-spectra NMRPipe seriesTab file through the GUI, several Error messages occur.
        * Added keyword dim to frontend function for spectrum.read_spins().  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.  This is associate data with the spins of up to two dimensions.
        * Implemented system test for reading spins from NMRPipe SeriesTab formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Extended reading of spin residue names from NMRPipe SeriesTab formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.

        * Insert check if spin already exist before creating it.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Issuing a warning instead of error when loading spins from Sparky list where residue names are not present.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Issued a warning instead of error when loading spin residue names from a NMRPipe SeriesTab formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Changed to use return_spin for testing presence of spin.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Implemented another system test for reading NMRPipe SeriesTab files.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Fix for issuing a warning in reading spins from a NMRPipe SeriesTab formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Fix for issuing a warning when reading spins from a Sparky formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Implemented system test for reading spin IDs from NMRView formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Made reading of NMRView formatted file return the residue number as integer instead of string.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Fix for calling the warn() function.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Extended the error description for reading NMRView files.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Implemented system test for reading spins from a NMRPipe SeriesTab formatted file whereby the assignments for second dimension is missing.  This will be a typically export from Sparky, converted to NMRPipe format, and processed with SeriesTab.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Fixed for reading spins from a NMRPipe SeriesTab formatted file whereby dimension 2 misses residue number and residue name.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Expanded the warning message for a system test.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Modified system test for reading an assignment whereby the second dimension is missing.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * If dimension 2 in a SeriesTab formatted file does not contain residue number+name, it defaults to the dimension 1.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Implemented system test for reading spins from an XEasy file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Modified XEasy reading function to pass residue names back.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Copied a SeriesTab file for the implementation of double assignments in Sparky files.
        * Redesign of the CPMG frequency and spin-lock field strength data structures.  These now have an extra dimension for the offset so that the values are now experiment, magnetic field strength and offset dependent.  If many offsets are present but are variable for each dispersion point, then this saves a lot of calculation time.  This mainly affects R1rho-type data.  To better handle this, all of the specific_analyses.relax_disp.disp_data.loop_*() functions have been modified to accept data values rather than indices.
        * Improved the printout of the relax_disp.r2eff_read_spin user function for the R2eff keys.
        * Extended the system test for reading spins from Sparky files with empty residue name+number second dimension assignment.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Modified the Sparky peak list for two dimensional assignment example.  This will typically be the export from CcpNmr Analysis.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Implemented a system test for using double assignments in Sparky formatted files.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Extended reading of spins from Sparky files for up to two dimensional assignments.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Added example of CcpNmr analysis exported Sparky file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Added system test for reading CcpNmr Analysis exported Sparky file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Modified the reading of Sparky files when exported from CcpNmr Analysis.  The keyword 'Data' is not present here.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Added a system test for using generic file for reading spins.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Modified the generic list to also return spin information when intensity is not present.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Added another system test for returning spins from a generic file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Added residue 4 to the R2eff files for the truncated CPMG data from Flemming Hansen.
        * Added cpmg_fit results to the software comparison table for Flemming Hansen's CPMG data.  The cpmg_fit input and log files have been added as well.
        * Shifted the software comparison down a directory so it can be used for all the different data.
        * Added system test for reading chemical shift from NMRPipe SeriesTab file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Implemented reading of chemical shifts from NMRPipe SeriesTab formatted files.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Additional chemical shift reading test for SeriesTab formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Improvements for the find_intensity_keys() dispersion analysis function.  This now handles the reference point None being converted to NaN in numpy arrays and the logic is now clearer.
        * Changed some warnings in the dispersion analysis so they only show if R1rho data is loaded.  This is for missing chemical shifts and R1 data.
        * Increased the size of the grid search in the Relax_disp.test_m61_exp_data_to_m61 system test.  This should increase the stability of this test.
        * Introduced the eliminate argument for the dispersion auto-analysis.  This flag allows model and Monte Carlo simulation elimination to be deactivated.
        * Updated two dispersion scripts in the test data directories to work with the current design.
        * Updated more test suite scripts to call the relax_disp.cpmg_frq user function.
        * The 'CR72' and 'MMQ CR72' models are now classified as nested in the dispersion auto-analysis.  The grid search for the 'MMQ CR72' model will therefore be skipped and the parameters taken from the 'CR72' model.  This will however rarely, if ever, be used.
        * Fix for the relax_disp.plot_disp_curves user function.  The interpolated curves now have all invalid points of 1e100 removed from the graph.  This allows for reasonable graph scaling.
        * The 'LM63' and 'LM63 3-site' models are now classified as nested in the dispersion auto-analysis.  The grid search for the 'LM63 3-site' model is therefore skipped and the starting parameters for optimisation are set to those of the optimised 'LM63' model.
        * Updated the relax results for the truncated CPMG data from Flemming Hansen.  This includes the new results for the 'MMQ CR72' model.  The analysis uses more model nesting.  And the Grace plots now include the interpolation graphs (hence the plots are now bzip2 compressed).
        * Updated the NESSY results for the truncated CPMG data from Flemming Hansen.  This now uses the data from all residues to allow for a proper error analysis so the results are comparable to all the other software.
        * Updated and reformatted the dispersion software comparison document.
        * Made a system test test pass on Mac OS 10.9.
        * Complete reworking of the 'NS R1rho 2-site' dispersion model.  The original code of Nikolai Skrynnikov and Martin Tollinger has been modified to match the behaviour of Dmitry Korzhnev's cpmg_fit software.  The equations from Korzhnev et al., JACS 2005 (http://dx.doi.org/10.1021/ja0446855) have been used for the initial magnetisation and the R1rho' calculation.  All equations have been added to the manual to clarify the model.
        * Both relax and cpmg_fit input and output files for the Fyn SH3 R1rho data have been added.  This is for the 'TP02' model and 'NS R1rho 2-site' models.  The cpmg_fit results include source code modifications to show the differences between the various 'corrections'.  The dispersion software comparison file has been updated to include this data and to show the cpmg_fit verses relax differences.
        * Updated the Relax_disp.test_tp02_data_to_ns_r1rho_2site system test.  This is for the fixes of the 'NS R1rho 2-site' dispersion model.
        * Added the Korzhnev 2005 R1rho constant time correction to the 'To do' section of the dispersion chapter of the user manual.
        * Removed the 'CR72' model for cpmg_fit from the dispersion software comparison table in the dispersion chapter of the user manual.
        * Removed the 'CR72' model for GUARDD from the dispersion software comparison table in the dispersion chapter of the user manual.  This software, like cpmg_fit, only supports the 'MMQ CR72' model which gives slightly different results to the original 'CR72' model when using only SQ CPMG-type data.  Hence supporting 'MMQ CR72' does not automatically mean that the 'CR72' model can be optimised.
        * Updated the ShereKhan error estimation technique in the dispersion software comparison table.  This is for the dispersion chapter of the user manual.  Adam Mazur communicated that errors are estimated using the covariance matrix in a private mail.
        * Large rearrangements in the dispersion chapter of the user manual.  The MMQ CPMG-type experiments now follow from the SQ CPMG-type experiments, hence the R1rho models are now listed last.
        * Added a to do entry for the 3-site and N-site analytic R1rho models listed in Palmer and Massi 2006.  This is for the 'To do' section of the dispersion chapter of the user manual.
        * Updated the lib.dispersion.ns_r1rho_2site module docstring to explain the origin of the equations.  This includes the Korzhnev 2005 reference where the modifications come from.
        * Created some synthetic data for the 'NS R1rho 3-site linear' dispersion model using cpmg_fit.
        * Added cpmg_fit results for the Fyn SH3 R1rho test suite data using the 3-site numeric solution.
        * Created the Relax_disp.test_ns_r1rho_3site_linear system test.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_test_suite.
        * Added the 'NS R1rho 3-site' models to the dispersion variables.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Adding_the_model_to_the_list.
        * Added the 'NS R1rho 3-site' models to the relax_disp.select_model user function frontend.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_front_end.
        * Changed the order of the experiment types in the relax_disp.select_model user function frontend.  The R1rho-type models have been shifted to the end so that the MMQ CPMG-type models are just after the SQ CPMG-type models.
        * Changed the 'CPMG-type' to 'SQ CPMG-type' in the relax_disp.select_model user function frontend.
        * Added support for the 'NS R1rho 3-site' models to the relax_disp.select_model user function back end.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' CPMG dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_back_end.
        * Decreased the amount of synthetic data in the ns_r1rho_3site_linear test suite shared data directory.  The number of offsets for this 'NS R1rho 3-site linear' model synthetic data has been decreased from 81 points to 21.  This is because the large quantities of data slow the test suite down too much.
        * Added a GUI test for reading spins from a spectrum formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Added the GUI key 'new spectrum' to point to 'spectrum.read_spins'.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Added the spectrum.read_spins GUI page for reading spins from a spectrum formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Added radio button for reading spins from a spectrum formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Further added to the GUI test for reading spins from spectrum formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Speed up of the Relax_disp.test_ns_r1rho_3site_linear system test.  Half of the data has been commented out, as too much data was being loaded for the test.
        * Created the target functions for the 'NS R1rho 3-site' models.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_target_function.
        * Added the R2eff calculating functions for the 'NS R1rho 3-site' models to the relax library.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_library.
        * Fix for GUI text string for the select radio button for reading spins from a spectrum formatted file.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Bug fix for the new 'NS R1rho 3-site' dispersion models - the Y and Z initial magnetisations were switched.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Debugging.
        * Added cpmg_fit results for the program modified to turn off the PEAK_SHIFT flag.  These are the results which should most closely match the relax results.  This is for the simulated R1rho data for the 'NS R1rho 3-site linear' model.
        * Fix for the MODEL_NS_R1RHO_3SITE_LINEAR dispersion variable.  The model name was not correct.
        * Turned off the dw dispersion parameter constraints for the 'NS R1rho 3-site' models.
        * Added the 'NS R1rho 3-site' models to the dispersion auto-analysis.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_auto-analysis.
        * Added the 'NS R1rho 3-site' models to the GUI model list.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_GUI.
        * Removed the pC <= pB constraint from the 3-site dispersion models.  This is important for the linear models where a violation of this constraint is reasonable.  This has been replaced by the pC <= pA constraint.
        * Added the 'NS R1rho 3-site' models to the relax user manual.  This is for the 'NS R1rho 3-site' and 'NS R1rho 3-site linear' dispersion models.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_manual.
        * Transposed some of the 'NS R1rho 3-site' model evolution matrix elements.  These now match the 'NS R1rho 2-site' model.
        * Last fixes for the 'NS R1rho 3-site' dispersion models.  These now behave identically to the cpmg_fit program with the PEAK_SHIFT flag disabled.  The tilt angle for the initial magnetisation is no longer that for the average offset but that of state A.
        * Fixes for swapped indices in the relaxation evolution matrix for the 'NS R1rho 3-site' dispersion models.
        * Docstring fix for the lib.dispersion.ns_r1rho_3site module.
        * Added the Omega_A,B,C resonance offset parameter definitions to the dispersion chapter of the manual.
        * Updated the relax results for the synthetic data of the 'NS R1rho 3-site linear' dispersion model.
        * Modified the 'NS R1rho 2-site' dispersion model to match the 'NS R1rho 3-site' models.  The 6D evolution matrix indices have been rearranged to match the 9D matrix indices.  The tilt angle for the initial magnetisation is no longer that for the average offset but that of state A, as was changed for the 'NS R1rho 3-site' models earlier.  The system test was therefore updated for the slightly different behaviour.
        * Updated the relax results for the Fyn SH3 R1rho dispersion data.  This is for the recent changes to the 'NS R1rho 2-site' dispersion model.
        * Updated the Relax_disp.test_ns_r1rho_3site_linear system test so it now passes.  The chi-squared value is not exactly zero as there are numerical differences between relax and cpmg_fit due to different approaches being used.
        * Added the RMSD determined via showApod for the 69 experiments.  Work in progress for Support Request #3083, (https://gna.org/support/index.php?3083) -  Addition of Data-set for R1rho analysis.
        * Added system test for the analysis of optimisation of the Kjaergaard et al., 2013 Off-resonance R1rho relaxation dispersion experiments using the 'DPL' model.  Work in progress for Support Request #3083, (https://gna.org/support/index.php?3083) -  Addition of Data-set for R1rho analysis.
        * Modified analysis script for example data of R1rho.  Work in progress for Support Request #3083, (https://gna.org/support/index.php?3083) -  Addition of Data-set for R1rho analysis.
        * Created synthetic R1rho dispersion data for the 'NS R1rho 3-site' model.  This is a simple modification of the data for the 'NS R1rho 3-site linear' model.  The k_AC parameter was simply changed from 0 to 1000.  The cpmg_fit software was used to create the data.  Both cpmg_fit and relax results have been updated to the new model.
        * Created the new Relax_disp.test_ns_r1rho_3site system test.  This was copied from the Relax_disp.test_ns_r1rho_3site_linear test and modified to use the new 'NS R1rho 3-site' model synthetic data.
        * Fix for wrong use of relax_fit.relax_time instead of relax_disp.relax_time.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Added the ns_r1rho_3site module to the lib.dispersion package __all__ list.  This allows the unit tests to pass.
        * turned off a system test until the release of relax 3.1.1 is over.  Work in progress for Support Request #3044 (https://gna.org/support/index.php?3044) - load spins from Sparky list.
        * Fix for the Relax_disp.test_bug_21076_multi_col_peak_list GUI test.  The peak intensity wizard is now closed at the end of the test so that subsequent tests can cleanly operate.  Without closing this wizard, launching it a second time in another test will always fail.
        * Capitalised 'Python' in the IO redirection messages.
        * Epydoc docstring fix for the lib.dispersion.ns_mmq_3site.r2eff_ns_mmq_3site_sq_dq_zq() function.  This allows the API to be compiled correctly.
        * Bug fix for the dispersion grid_search_setup() optimisation function.  This function was not updated for the recent addition of the spin-lock or hard pulse offset dimension in the specific_analyses.relax_disp.disp_data module (and hence all structures used by the dispersion target functions).  The loop_exp_frq_point() function call has been replaced by a loop_exp_frq_offset_point() function call to allow the 'R2eff' model parameters to be looped over.  For more details, see the thread http://thread.gmane.org/gmane.science.nmr.relax.scm/19685.  This solution was mentioned at http://thread.gmane.org/gmane.science.nmr.relax.scm/19685/focus=4859.
        * Removed a printout from the Relax_disp.test_r1rho_kjaergaard GUI test as this is fatal for Python 3.
        * Python 3 fixes for the relax_disp.r2eff_read_spin user function.  The check for the dispersion point column now only runs if that argument is set.  In addition, the offset column is now also being checked.


    Bugfixes:
        * Fix for the sample_scripts/relax_disp/R1rho_analysis.py sample script.  This was identified by Justin Lecher <jlec att gentoo doot org> in the post http://article.gmane.org/gmane.science.nmr.relax.devel/4748 (Message-ID:<52984043.3030808@gentoo.org>), or the threaded view http://thread.gmane.org/gmane.science.nmr.relax.announce/46/focus=4748.  The problem was some extra commas which should not have been there.
        * Bug fixes for the non-functional R1rho_analysis.py relaxation dispersion sample script.  This script was horribly broken, but it should now work.  It can even be executed from the base relax directory or from within the sample_scripts/relax_disp/ directory and perform the full analysis (assuming write access to the relax source directory).
        * Fix for a number of PNG files for NESSY and Bruker icons for broken IDAT entries.  This problem was identified by Justin Lecher <jlec att gentoo doot org> in the post http://article.gmane.org/gmane.science.nmr.relax.devel/4750 (Message-ID:<5298572C.5010409@gentoo.org>), or in the threaded view http://thread.gmane.org/gmane.science.nmr.relax.announce/46/focus=4750.  As a result those icons are missing in the GUI.  This was fixed using the pngcrush tool.
        * Fix for a typo in a model name in the cpmg_analysis.py relaxation dispersion sample script.
        * Fix for bug #21309, the 'R2eff' dispersion model failure when peak intensity data is missing.  The bug is reported at https://gna.org/bugs/?21309.  The problem was that the check for missing data in the _calculate_r2eff() private API method was accidentally deleted in the relax_disp branch.  See the commit at http://article.gmane.org/gmane.science.nmr.relax.scm/19261 and the accidental deletion at http://svn.gna.org/viewcvs/relax/branches/relax_disp/specific_analyses/relax_disp/api.py?view=diff&r1=21504&r2=21505&pathrev=21505.
        * Another fix for bug #21309, the 'R2eff' dispersion model failure when peak intensity data is missing.  The bug is reported at https://gna.org/bugs/?21309.  This second problem is only for the numeric CPMG models for when all data at one magnetic field strength is missing.  When the relaxation dispersion target function is being set up, the creation of the self.power data structure holding the number of CPMG blocks fails.  The problem is that the relaxation time for the missing field strength is set to NaN.  This is now caught using lib.float.isNaN().
        * Loosened a check in the Relax_disp.test_hansen_cpmg_data_missing_auto_analysis system test.  This is to allow this test to pass on certain Mac OS X machines.  It was reported by Troels in the post http://thread.gmane.org/gmane.science.nmr.relax.devel/4773/focus=4774.
        * Basic fix for the Relax_disp.test_r2eff_read_spin system test - the CPMG frequencies are now set.  This was identified in the post http://thread.gmane.org/gmane.science.nmr.relax.devel/4773/focus=4774.
        * Fixes for the parameters in the Relax_disp.test_ns_mmq_3site system test script.
        * Fix for optimisation of Dr. Flemming Hansen's CPMG data to the 'NS CPMG 2-site star' dispersion model.  Fix for bug #21322, (https://gna.org/bugs/?21322) - 5x Test suite fail for version 3.1.0, reported for system CentOS 2.6.32-358.18.1.el6.x86_64.  Adjusted pA, dw, kex, chi2.
        * Fix for optimisation of the Korzhnev et al., 2005 15N DQ CPMG data using the 'MMQ 2-site' model.  Fix for bug #21322, (https://gna.org/bugs/?21322) - 5x Test suite fail for version 3.1.0, reported for system CentOS 2.6.32-358.18.1.el6.x86_64.
        * Fix for optimisation of the Korzhnev et al., 2005 15N MQ CPMG data using the 'MMQ 2-site' model.  Fix for bug #21322, (https://gna.org/bugs/?21322) - 5x Test suite fail for version 3.1.0, Reported for system CentOS 2.6.32-358.18.1.el6.x86_64.
        * Fix for optimisation of the Korzhnev et al., 2005 15N ZQ CPMG data using the 'MMQ 2-site' model.  Fix for bug #21322, (https://gna.org/bugs/?21322) - 5x Test suite fail for version 3.1.0, Reported for system CentOS 2.6.32-358.18.1.el6.x86_64.
        * Fix for optimisation of all the Korzhnev et al., 2005 CPMG data using the 'MMQ 2-site' model.  Fix for bug #21322, (https://gna.org/bugs/?21322) - 5x Test suite fail for version 3.1.0, Reported for system CentOS 2.6.32-358.18.1.el6.x86_64.
        * Fix for optimisation of Dr. Flemming Hansen's CPMG data to the 'NS CPMG 2-site star' dispersion model. Changed so assertAlmostEqual matches 2 digits.  Fix for bug #21322, (https://gna.org/bugs/?21322) - 5x Test suite fail for version 3.1.0, reported for system CentOS 2.6.32-358.18.1.el6.x86_64.
        * Bug fixes for the dispersion analysis when certain data sets are completely missing.
        * Fix for loading a seriesTab formatted intensity, and getting the ID for the following GUI elements.  Fix for bug #21076, (https://gna.org/bugs/?21076) - when loading a multi-spectra NMRPipe seriesTab file through the GUI, several Error messages occur.
        * Fix for the relax_disp.r2eff_read_spin user function.  The offsets are now converted to ppm prior to finding the R2eff/R1rho key.

    Changes:
        * Started to implement the framework for relaxation dispersion system tests.
        * Copied 'test_suite/system_tests/relax_fit.py' for relaxation dispersion.
        * Started to implement relaxation dispersion system tests.
        * Created the user_functions.relax_disp module by copying user_functions.relax_fit.  This file now needs to be modified to suit the needs of relaxation dispersion.
        * Manually created the relax_disp user functions.  This is equivalent to Seb's commit for the prompt.relax_disp module.  The equivalent changes to the user_functions.relax_disp were hand edited.  Added functions to select the experiment type and mathematical model used.  These functions allow the user to select the experiment type (cpmg or r1rho) as well as the mathematical model to fit the data (fast or slow).
        * Copied the 'relax_fit.py' script to 'relax_disp.py'.  This file, obviously, will need to be modified to suit the needs of the relaxation dispersion code.
        * Modified the script so it will test for fast-exchange curve fitting from CPMG data.  Data and functions to treat it are still missing.
        * Added a test for CPMG data in slow-exchange and changed the name of the test for fast-exchange.
        * Copied the 'relax_fit.py' specific functions to 'relax_disp.py'.  The code will now need many many many changes to suit the needs of relaxation dispersion.
        * Made a few changes towards a functional relaxation dispersion code.  This includes several modifications as well as the addition of the exp_type() function.
        * Moved the relax_time() function to cpmg_frq() and made other small changes.  Still much (!) work is needed for this code to be complete.
        * Renamed 'cdp.frq' to 'cdp.cpmg_frqs' so it is not confusing with the spectrometer frequency.  Indeed, 'cdp.cpmg_frqs' points to the CPMG pulse train frequency (nu_cpmg).
        * Changed all instances of 'relax_times' to 'cpmg_frqs' and made other small changes.
        * Changed 'relax_time' instances to 'cpmg_frq'.
        * Changed the index name and description.  The description might change later to be more appropriate when the code is more mature...
        * Included the setting of the spectrometer frequency and uncommented a few lines of code.  Of course, this won't work until the sample data has been introduced and the right names for the different files be input in the system test script...
        * Fixed many formatting errors and made the 'relax_disp' code accessible (pipes, interpreter, etc.).  These changes also include a coming back to using the C code 'math_fns/relax_fit.py' since there is still no such code associated to relaxation dispersion.  This will allow working in the code without relax crashing and complaining about the lack of a C module name 'relax_disp.py'.
        * Added the user function cpmg_delayT() which allows setting the CPMG constant time delay T used for the analysed dataset.  This follows a post at https://mail.gna.org/public/relax-devel/2009-01/msg00027.html.
        * Made a few changes so the cpmg_delayT() function now works.
        * Added the user function cpmg_frq() and added examples to the user function cpmg_delayT().
        * Corrected remaining frq instances to cpmg_frq when appropriate to avoid confusion and corrected a few related things in the system test script.
        * Made the cpmg_frq() function accept only None for the reference spectrum and corrected a typo.
        * Added the parameters for the slow- and fast-exchange regime.
        * Added the parameters for the slow- and fast-exchange regime in the function data_names().
        * Corrected a few formatting issues and still added parameters for the slow- and fast-exchange regime.
        * Corrected a few formatting issues and still added parameters for the slow- and fast-exchange regime.  Formatting issues corrected were spotted by Ed in a post at https://mail.gna.org/public/relax-devel/2009-01/msg00045.html.
        * A bit more changes to introduce parameters for CPMG relaxation dispersion.
        * Introduced CPMG parameters into the function return_grace_string() and corrected formatting issues.
        * Introduced relaxation dispersion parameters in the function return_data_name().
        * Changed the default cpmg_frq value in cpmg_frq() from 0 to None.
        * Added a relaxation dispersion dataset in the system-test.  This was kindly provided by Dr Flemming Hansen (flemming AT pound DOT med DOT utoronto DOT ca) and was previously published in Hansen, Vallurupalli & Kay (2008) J. Phys. Chem. B, 112, 5898-5904.  The original format was different and was modified to better suit the way relax handles datasets.  Finally, the information contained here were written in a 'readme' file placed in the same directory as the dataset itself to allow referencing and acknowledgments.
        * Added 'Sparky' formatted files to the system-test so the files can be input and development of the branch continued.
        * Changed the format of the CPMG frequency and corrected the names of some input files.
        * Added an unresolved file to meet the script requirements.
        * Copied the script for the fast-exchange regime to the slow-exchange regime.
        * Modified the newly copied script so it is effectively for the slow-exchange regime.
        * Added details to the readme file and changed the directory name where the sample data is located.  The directory is now named 'dataset_1-a'.  This contains data recorded at 500 MHz.  Data recorded at 800 MHz will be put in a directory called 'dataset_1-b'.
        * Created a directory for the data recorded at 800 MHz and put a readme file explaining its origin.
        * Added the relaxation dispersion dataset recorded at 800 MHz in the system-test.  This was kindly provided by Dr Flemming Hansen (flemming AT pound DOT med DOT utoronto DOT ca) and was previously published in Hansen, Vallurupalli & Kay (2008) J. Phys. Chem. B, 112, 5898-5904.  The original format was different and two formats were made ('generic' and 'sparky'), as for the dataset recorded at 500 MHz.
        * Renamed the directories containing the sample datasets provided by Flemming Hansen.  The names are now more obvious as to their content...  This was proposed by Ed in a post at https://mail.gna.org/public/relax-devel/2009-01/msg00056.html.
        * Added an 'unresolved' file to the 800 MHz data and moved (and modified) some files (sequence and readme) so there is only one copy for the 500 and 800 MHz data.  This prevents duplicated files.
        * Changed the object names so they are lower case as they should be, based on the rest of the code.  Made the equivalent change in the function assemble_param_vector() to allow the system-test to go further..  This was spotted by Ed in a post at https://mail.gna.org/public/relax-devel/2009-01/msg00058.html.
        * Corrected capitalisation issues for param names.  These were spotted by Ed in a thread starting at https://mail.gna.org/public/relax-devel/2009-01/msg00059.html.
        * Rearranged commands in the scripts.  The experiment type and exchange regime will have to be input before the cpmg pulse train delay T.
        * Introduced a RelaxError when chosing 'r1rho' as experiment type as this won't be implemented now.  Efforts will be concentrated on the CPMG code first, then on the R1rho code.
        * Added tests, print statements and other code to the relaxation dispersion specific functions.  Tests were proposed by Ed in a post at https://mail.gna.org/public/relax-devel/2009-01/msg00065.html.
        * Started to implement a function for calculating the effective transversal relaxation rate (R2eff).  This follows a thread at https://mail.gna.org/public/relax-devel/2009-01/msg00067.html.
        * Converted the function linear_constraints() for relaxation dispersion needs.
        * Started to implement the scaling matrix for scaling the 'R2eff' values.  This might change in the future as other possible curve fitting parameters ('R2', 'Rex', 'kex', 'R2A', 'kA', 'dw') might need some scaling.
        * Completed the scaling matrix code.  This follows a thread at https://mail.gna.org/public/relax-devel/2009-01/msg00073.html.
        * Imported relaxation dispersion in grace user functions.
        * Added a missing quote which prevented the user manual to be sconstructed.  This was discussed in a thread starting at https://mail.gna.org/public/relax-devel/2009-01/msg00082.html.
        * Started to implement a function for reading 'R2eff' values directly.  This is as proposed in a post at https://mail.gna.org/public/relax-devel/2009-01/msg00020.html.  The function does not contain code yet.
        * Started to put equations and references in the user function docstrings and also corrected a small typo.  This was proposed by Ed in a post at https://mail.gna.org/public/relax-devel/2009-01/msg00028.html.
        * Corrected the way the scaling matrix is assembled.  This is as proposed by Ed in a post at https://mail.gna.org/public/relax-devel/2009-01/msg00079.html.  The scaling values are now based on the default values for the different parameters which were slightly modified.  The only parameter for which the average is still used (as for intensities in the 'relax_fit.py' code) is 'R2eff'.
        * Continued to implement the user function calc_r2eff().  This follows a discussion at https://mail.gna.org/public/relax-devel/2009-01/msg00067.html.
        * Copied 'test_relax_fit.py' to 'test_relax_disp.py'.  This will allow the design of a few unit tests for the relaxation dispersion code.
        * Added two unit tests for the relaxation dispersion code and fixed errors in the corresponding code.  More unit tests will be added soon to help debugging and developing.
        * Added two more unit tests.
        * One more unit test.
        * One more unit test for the relaxation dispersion code.
        * Added more unit tests and tried to debug what was uncovered by these tests.  Still more work is needed for debugging...
        * A few fixes based on the unit tests problems.
        * Changed the default value for 'int_cpmg' to avoid an impossible mathematical situation: ln(0).
        * Fixed a bug where the 'id' argument was not set.  This was proposed by Ed in a post at https://mail.gna.org/public/relax-devel/2009-01/msg00127.html.
        * Started to make changes for multiple field relaxation dispersion analysis.  This seems necessary, so maybe we should not support single field analysis of relaxation dispersion at all.  -> Kovrigin et al. (2006) JMagRes, 180: 93-104.  The changes made here are only a first draft and may not work.  In particular, maybe the spectrum.read_intensities(), relax_disp.cpmg_frq(), spectrum.replicated(),  spectrum.error_analysis(), and deselect.read() functions will need to know the magnetic field to which the particular dataset is associated...  In fact, the different datasets should be input first and their R2eff calculated independently.  In a second step, the actual relaxation dispersion curve fitting should be made with all data.
        * Fixed a bug which prevented the manual pdf to be compiled.  The problem was caused by a ':' character in the references (after the volume number, as usual).  This was changed for a '.' character.  Equations were fine..  Moreover, a better formatting was done by adding ':' characters after the word 'are' before enumerations.
        * Fixed the unit tests.  This is as proposed by Ed in a post at https://mail.gna.org/public/relax-devel/2009-01/msg00132.html.
        * Started to implement the reading of 'r2eff' by relax_data.read() by first writing a system test.
        * Updated a few dosctrings and tried to improve the system test.
        * Removed the obsolete function 'relax_disp.r2eff_read()'.  R2eff values will be read directly by 'relax_data.read()'.
        * Reordered a few functions for alphabetical reasons.
        * A small fix to the system test.  However, is this fix the solution or is there something wrong with the reading of data (such as 'R2eff') by relax_data.read()?  Shouldn't the data, for example 'R2eff', be available in 'cdp.mol[0].res[0].spin[0].R2eff_val[0]' or 'cdp.mol[0].res[0].spin[0].R2eff[0]' for the 1st spin of the 1st residue in the 1st molecule?
        * Fixed an import (as well as a few comments).  This however introduces an error concerning the 'chi2' being undefined in the C module for relaxation dispersion...
        * Solved an issue created during the merge process concerning the 'return_data_name_doc' call.  The solution is based on the code in 'specific_fns/relax_fit.py'.
        * Brought the relaxation dispersion branch into sync with the 1.3 line.  There were many design changes within the 1.3 line that required that the old relaxation dispersion code be updated.
        * Fixes for the relaxation dispersion system tests.  The install path is now in the status object, and not in __main__.
        * GPLv3 license updates for all files not found in the trunk.
        * Import fixes for the specific_analyses.relax_disp due to the recent trunk package layout redesign.
        * Made the non-API methods of the specific_analyses.relax_disp.Relax_disp class private.
        * Improvements for the GUI representation of the relax_disp user functions.
        * More import fixes for the new package layout.
        * Fix for the relax_data.read user function call in the Relax_disp.test_read_r2eff system test.  The column numbers must be supplied.
        * Some more fixes to make the Relax_disp.test_read_r2eff system test pass.  These are again changes needed due to the trunk now being very different.
        * The cpmg_frq argument of the relax_disp.cpmg_frq user function can now be None.
        * The cpmg_frq argument of the relax_disp.cpmg_frq user function can now be an integer as well as a float.
        * Updates for the relaxation dispersion system test scripts for the newer design of relax.  A number of changes were required as the code was quite old.
        * Created the lib.dispersion.equations module.  This is a translation of Sebastien Morin's C code in the old relax_disp branch.
        * Created a very basic initial target function class for relaxation dispersion.  This code is a translation of Sebastien Morin's C code in the old relax_disp branch.
        * The relaxation dispersion specific analysis code now uses the Python target function rather than the C.
        * Fix for the Relax_disp.test_curve_fitting_cpmg_fast system test variable names.
        * Added the model argument to the dispersion target function class to select between different equations.
        * The relaxation dispersion target function class now imports the equations from lib.dispersion.equations.
        * The relaxation dispersion target function class raises a RelaxError when the model is not implemented.
        * Modified all the relaxation dispersion test data Sparky files at 800 MHz.  The last three lines of the files were not properly formatted.
        * Converted all of the raising of RelaxErrors in the specific_analyses.relax_disp to the new standard.  This is for Python 3 support.
        * Converted all print statements in specific_analyses.relax_disp to function calls.  This is for Python 3 compatibility.
        * Converted the prompt unit tests for relaxation dispersion to the current relax design.
        * Updated the target_functions package __all__ list for the relax_disp module.
        * Another fix for the prompt argument unit tests of the relax_disp user functions.
        * Big changes to the front end of the relax_disp.select_model user function.  The model strings have been changed and are now programmatically added to the user function documentation.  The main text has also been redesigned.  And the new model 'exp_fit' has been added which allows just the exponential curves to be fit.
        * Python 3 import fix for the specific_analyses.relax_disp module.
        * Updated the documentation in specific_analyses.relax_disp to use the user_functions package design.  The user_functions.objects.Desc_container and user_functions.data.Uf_tables objects are now used to construct the relaxation dispersion documentation.
        * The relax_disp.select_model backend now handles the 'exp_fit' model.
        * Removed all aliasing of the current data pipe in specific_analyses.relax_disp as this is in __builtin__.
        * The specific_analyses.relax_disp module now uses the parameter list object to define parameters.  This allows the now unused methods data_names(), default_value(), return_data_name(), and return_grace_string() to be deleted and their contents copied into the parameter definitions in the class __init__() method.
        * Alphabetical arrangement of methods in the specific_analyses.relax_disp module.
        * Docstring cleanups for the specific_analyses.relax_disp module.
        * The relaxation dispersion specific analysis now aliases API base methods for a number of methods.
        * Import cleanup in the specific_analyses.relax_disp module.
        * The relaxation dispersion specific analysis module is now using the base _data_init_spin() method.  This is aliased to data_init() and replaces the old non-functional method.
        * Created the relax_disp.spin_lock_field user function.  This is used to set the spin-lock field strength of a given R1rho spectrum.
        * Created the relax_disp.relax_time user function.  This is almost a direct copy of the relax_fit.relax_time user function, but has been modernised.
        * Fix for the printout from the relax_disp.relax_time user function - the time is no longer divided by 1k.
        * Expanded the dispersion model parameters to include the exponential curve parameters.
        * Clean up of some of the old relax_disp user functions - many argument types are now numbers rather than floats.
        * Unit test fixes for the prompt relax_disp user function argument checks.
        * Added the specific_analyses.relax_disp module to the unit test checking of the specific API.
        * Big cleanup of the relaxation dispersion code to match the analysis specific API.  All methods not belonging to the API have been made private.  The arguments and keyword arguments for the API methods now match the API.
        * Completely redesigned the minimisation parts of the specific_analyses.relax_disp module.  Instead of dealing with the optimisation of individual spins, groups of spins are now optimised together.  This allows for the clustering analysis of relaxation dispersion.  The method _block_loop() has been created to loop over spin blocks, but it currently only returns individual spins.  However with the rest of the code designed to handle this loop, only this function needs to be modified to enable clustering.  The method _param_num() has also been added to determine the total parameter number per spin block.  The data structures sent into the Dispersion target function class have also been redesigned to handle spin blocks instead of individual spins.
        * Modified the relax_disp.cpmg_frq user function to match relax_disp.spin_lock_field.  Both the front and back ends now use the same logic as the relax_disp.spin_lock_field user function and will allow some sanity to the analysis specific code.
        * The relax_disp.cpmg_frq and relax_disp.spin_lock_field user functions now create cdp.curve_count.  This is an integer which indicates the number of exponential curves which are to be optimised per spin block.
        * The relaxation dispersion analysis specific _param_num() method now takes the number of curves into account.
        * Better setup checking for the relaxation dispersion specific analysis minimise() method.
        * Renamed cdp.curve_type to cdp.model to better explain the variable.
        * Fixes for the dispersion specific analysis separating R2eff from R2.  There is one R2eff parameter per exponential curve, but only one R2 per model.  The code now better handles this.
        * The dispersion specific methods now handle one R2eff and I0 parameter per exponential curve.
        * Better management of the global relaxation dispersion data.  The user functions relax_disp.cpmg_frq, relax_disp.spin_lock_nu1, and relax_disp.relax_time now maintain data structures in the current data pipe of the unique frequencies, fields, and times (sorted) as well as the number of frequencies, fields, and times.  This data is used by the minimise user function back end to set up the target function, and will be required by many other parts of the analysis.
        * The dispersion specific _assemble_param_vector() method now handles multiple R2eff and I0 values.  These spin structures are dictionaries holding multiple values.
        * Created the dispersion specific _exp_curve_loop() method for looping over each exponential curve.  This yields the index and key for each curve, simplifying the handling of this data.
        * Expanded the relax_disp.select_model user function documentation to cover R2eff and I0.  These parameters and how they are optimised are now better described.
        * Updated the relaxation dispersion target function class to handle the recent changes.
        * First attempt at a target function for fitting exponential curves for relaxation dispersion.
        * Added some synthetic data to test the 'exp_fit' relaxation dispersion model fitting.  These are just basic synthetic exponential curves.  R2eff and I0 should be very easy to find.
        * The lib.software.sparky.read_list_intensity() function can now handle lowercase in the residue names.
        * Created the Relax_disp.test_exp_fit system test for checking the relaxation dispersion 'exp_fit' model.
        * The specific_analyses.relax_disp module is now using minfx correctly.  The minfx grid search is no longer part of generic_minimise() and must be called separately.
        * The relax_disp function _grid_search_setup() now operates in the same way as the relax_fit code.  This function originates from the 'relax_fit' specific analysis code, but that code has since evolved.  The 'relax_disp' code now mimics the new code, returning lists of grid search increments and upper and lower limits.
        * The scaling flag is now initialised in the relaxation dispersion target function class.
        * Created the lib.curve_fit package and associated unit tests.  This will be used for holding modules such as for exponential curve-fitting required for the relaxation dispersion analysis.
        * Created the new lib.curve_fit.exponential module for exponential curve-fitting.  This contains the single exponential_2param_neg() function which will be used for the relaxation dispersion target functions.  This is based on Sebastien Morin's function exp_2param_neg in maths_fns.exponential.c in his dormant inversion-recovery branch.
        * Typo fix for the new lib.curve_fit.exponential.exponential_2param_neg() function.
        * The relaxation dispersion func_exp_fit() target function now uses exponential_2param_neg().  This is from the lib.curve_fit.exponential module.
        * Fix for the relaxation dispersion specific _assemble_scaling_matrix() method.  The values were all inverted - the matrix should hold values on the same order as the parameter values.
        * Fix for the func_exp_fit() relaxation dispersion target function.  The parameter index was not correctly calculated.
        * The 'exp_fit' relaxation dispersion model now uses the minfx.grid sparseness argument.  This is used to skip all parts of the grid search belonging to a different exponential curve or different spin.  If the number of curves is N and the number of spins M, the grid size decreases from inc**(2*N*M) to (inc**2)*N*M.  For lots of spins and curves, this is a huge decrease.
        * The relaxation dispersion specific _disassemble_param_vector() method is now functional.  This should allow the minimise user function to complete.
        * Fixes for the dispersion specific _assemble_param_vector() method.  The R2eff and I0 spin dictionary structures are now checked for their keys before pulling the value out.
        * Fix for the relaxation dispersion grid search.  The lower and upper bounds are no longer continually scaled with each optimisation.
        * Increased the speed of the Relax_disp.test_exp_fit system test by using a smaller grid search.
        * The relaxation dispersion target function class back_calc variable now matches the values variable.  Instead of being a temporary structure which is overwritten for each spin and each exponential curve, the structure now matches the dimensions of the values variable and hence is persistent per function call.  This allows external code to access the structure - for example for data back calculation in the relaxation dispersion specific analysis module.
        * Fixes for the dispersion specific _back_calc() method.  This method still has a long way to go before it is of any use.
        * Created a custom base_data_loop() method for the relaxation dispersion analysis.  This defines the base data as the peak intensities of a single exponential curve and yields the spin container and exponential curve key identifying the individual curves.
        * Activated Monte Carlo simulations for the relaxation dispersion analysis.  This required a bit of work.  The key parts were renaming _block_loop() to the API method model_loop() as that is exactly what the model_loop() method is supposed to do, converting a bunch of API common spin-based methods to handle dispersion clustering, and to modify existing methods from Seb's original branch to handle the base_data_loop() method.  The following methods have been added or modified.  _back_calc():  This method has been modified to handle clustering and the returning of peak intensities from only one exponential curve.  _exp_curve_index_from_key():  This new method is used to convert exponential curve key into the corresponding index.  _intensity_key():  This new method is for converting an exponential curve key and relaxation time into the corresponding intensity key.  create_mc_data():  This method is now functional and handles the data from the base_data_loop() method.  return_error():  This method now handles the data from the base_data_loop() method.  set_selected_sim():  This new method has been modified from the common _set_selected_sim_spin() method but modified for the model_loop() method.  sim_pack_data():  This method now handles the data from the base_data_loop() method.  sim_return_param():  This new method has been modified from the common _sim_return_param_spin() method to suit the model_loop().  sim_return_selected():  This new method has been modified from the common _sim_return_selected_spin() method again to suit the model_loop().
        * Modified the Relax_disp.test_exp_fit system test to be faster and not create plots which it cannot.
        * The Relax_disp.test_exp_fit system test now checks some of the final results.
        * The relaxation dispersion parameter errors from Monte Carlo simulations are now stored.  Previously MC simulations could run, but the errors were not being calculated and stored.  The sim_return_param() method was empty.  This method is now complete.  In addition the set_error() method has been created for setting the parameter errors.  And the _exp_curve_key_from_index() and _param_index_to_param_info() auxiliary methods added to facilitate data access.
        * Expanded the checking in the Relax_disp.test_exp_fit system test.
        * Converted all relaxation dispersion parameters to lowercase.  This is so the variable names match the parameter names identically, avoiding problems with some of the shared methods of the specific analysis API.
        * The spin parameters are now set up last by the relax_disp.select_model user function back end.
        * Added 'spin_lock_nu1' as a dictionary type parameter of the relaxation dispersion specific analysis.
        * Rearrangements of the 2 system tests of Fleming Hansen's CPMG data.  The system tests are now called Relax_disp.test_hansen_cpmg_data_fast_2site and Relax_disp.test_hansen_cpmg_data_slow_2site, and the system test scripts are now all in test_suite/system_tests/scripts/relax_disp/.
        * Created a basic initial auto-analysis script for relaxation dispersion.  This currently only supports the optimisation of the 'exp_fit' diffusion model, but has all of the infrastructure set up to make it easy to add other models.
        * Added the relaxation dispersion module to the auto_analyses package __all__ list.
        * The relaxation dispersion system test class now imports the auto-analysis.  This fixes an import order error.
        * The Relax_disp.test_exp_fit system test now uses the auto_analyses.relax_disp analysis.
        * Fix for the relaxation dispersion auto-analysis.  The exponential fit model is now selected prior to optimisation.
        * Removed the relax_disp.select_model user function call from the exp_fit dispersion system test script.  This is performed by the auto-analysis and not during setup.
        * Added testing for spin clustering to the Relax_disp.test_exp_fit system test.  This includes calls to the new relax_disp.cluster user function and the checking of pipe variables holding the clustering information.
        * Fix for the spin ID string for the relax_disp.cluster user function.  This is for the exp_fit.py relaxation dispersion system test script.
        * Implemented the relax_disp.cluster user function.  This is for clustering spins together for a dispersion analysis.
        * Clustering is now enabled for relaxation dispersion.  The model_loop() analysis specific API method now loops over the spin clusterings, allowing a cluster of spins to be optimised simultaneously to one set of model parameters.
        * Fixes for the spin clustering for relaxation dispersion.  Both optimisation and Monte Carlo simulations were affected by these bugs.
        * Speed up of the Relax_disp.test_exp_fit system test by cutting the grid size down to 3 increments.
        * Expanded the write_results() method of the relaxation dispersion auto-analysis.  More Grace graphs are now being produced, and the Rex file creation is now model dependent.
        * Fix for the relax_disp.cluster user function.  The 'free spins' category is now not deleted when empty.
        * Created an icon set for relaxation dispersion.
        * Renamed the relaxation dispersion test suite data directory to 'dispersion'.
        * Changed the relax_disp.cpmg_frq user function id argument to spectrum_id.  All the relax_disp user functions now operate with the spectrum IDs instead of experiment IDs.
        * The relax_disp.cpmg_delayT user function backend now uses the spectrum ID rather than experiment ID.
        * Expanded the relax_disp.exp_type user function to include the fixed period CPMG experiments.
        * The relax_disp.cpmg_delayT backend can now handle the 'cpmg fixed' experiment type.
        * The relax_disp.cpmg_frq user function can now handle values of None.  The float function is no longer used if the value of None is encountered.
        * Updated the dispersion system test script for Flemming Hansen's data.  This script should now be close to the final form for a relaxation dispersion analysis of CPMG data with a fixed relaxation time period.
        * Combined all the system test scripts of Flemming Hansen's fixed time period CPMG data.  For details of this data, see http://thread.gmane.org/gmane.science.nmr.relax.devel/3790/focus=3827.
        * Fixes for the renaming of the relaxation dispersion test suite shared data directory.
        * Started to redesign how R2eff is handled in the relaxation dispersion analysis.  Instead of being part of the optimisation of the dispersion model, it will itself be the model named 'R2eff' (converted from the 'exp_fit' model).  This model will either use the calc user function to determine R2eff when the fixed relaxation period experiment is selected, or fit exponential curves using the relax_fit C module for the variable relaxation period experiments.  The R2eff values will then be copied over for each dispersion model in the auto-analysis using the value.copy user function.
        * Created the relax_disp.plot_exp_curves user function.  This is to be used to create 2D graphs of the exponential curves (relaxation time verses peak intensity) as the grace.write user function plots are not very nice - the curves from each spectrometer field strength and dispersion point are mixed into one curve.
        * The relaxation dispersion auto-analysis is now created plots of the exponential curves.
        * The R2eff model now works for the variable time relaxation period and exponential curve-fitting.
        * The relax_disp.select_model user function now checks for the compiled C module when required.
        * Expanded the new analysis wizard in the GUI to accommodate the relaxation dispersion auto-analysis.  Now the buttons are a matrix of 4x2 with the NOE, R1, R2, and model-free analyses at the top and two new blank buttons have been added to the bottom.  One will be used for the dispersion analysis.
        * Created some basic graphics for the relaxation dispersion analysis fur use in the GUI.
        * Added the correct sized graphic for the relaxation dispersion button in the new analysis wizard.
        * Created the relaxation dispersion button in the new analysis wizard.
        * Created the initial version of the relaxation dispersion auto-analysis GUI frame.  This is built from copying lots of code from the NOE, R1, and R2 analyses.  The dispersion specific parts will be added later.
        * The relaxation dispersion GUI analysis now has an element for selecting the models to be optimised.
        * Removed some unneeded checks in the relax_disp.exp_type user function.
        * Added a GUI element to the relaxation dispersion auto-analysis for selecting the experiment type.
        * The relax_disp.exp_type user function has been shifted to the new analysis wizard.  Instead of being one of the elements on the relaxation dispersion analysis frame, it is now placed between the analysis selection page and the data pipe page of the new analysis wizard.  The user function execution is delayed until the set up of the frame, just after the execution of the pipe.create user function.  This will allow the frame to be set up differently for each experiment type.
        * Extended the tooltip for the experiment type GUI element in the relaxation dispersion frame.
        * Improvements to the tooltips in the relaxation dispersion analysis frame of the GUI.
        * Changed the peak intensity wizard for the relaxation dispersion frame to match the other analyses.
        * Unused import removal from the gui.analyses.auto_relax_disp module.
        * Missing import in the gui.analyses.auto_relax_disp module.
        * Added support for all the relaxation dispersion user functions in the Peak_intensity_wizard object.
        * Modified how the fixed time period is specified in the Flemming Hansen data system test.  Instead of using relax_disp.cpmg_delayT user function, the relax_disp.relax_time user function will be used.  The functionality is duplicated and relax_disp.cpmg_delayT is not needed.
        * Modified the Spectra_list GUI element to handle relaxation dispersion data.
        * The relaxation dispersion GUI analysis now uses the dispersion parts of the peak intensity elements.  This includes activating the dispersion parts of the Spectra_list GUI element for displaying the spectrum ID with associated metadata and the dispersion parts of the Peak_intensity_wizard for loading the data.
        * The relaxation dispersion auto-analysis is now correctly executed from the GUI.  The GUI data gathering is also now complete in the assemble_data() method.
        * Added some more module variables to specific_analyses.relax_disp for the experiment types.
        * The relaxation dispersion auto-analysis now performs the peak intensity error analysis.  This is essential for when the GUI is used.
        * More Unicode characters are now used in the relaxation dispersion GUI analysis frame.  The model parameter lists have also been improved.
        * Removed the spectrum.error_analysis user function call in the exp_fit.py dispersion system test script.  This is now performed by the auto-analysis.
        * Fixed for the error_analysis() method of the relaxation dispersion auto-analysis.  The method can now handle missing spectrometer field strength data.
        * More fixed for the peak intensity error analysis method of the relaxation dispersion auto-analysis.  The fixed relaxation time period type experiments can now be handled.
        * Elimination of the relax_disp.cpmg_delayT user function.  This user function is not necessary as the relax_disp.relax_time user function serves the same purpose.  The use of relax_disp.relax_time instead allows for code sharing between the fixed and variable time period relaxation dispersion experiment types.
        * Elimination of the relax_disp.calc_r2eff user function.  This user function, which is non-functional anyway, is not needed.  The calculation of the R2eff values will occur with the optimisation of the 'R2eff' model (with a call to the calc user function for the fixed time period experiment types) so direct calculation through a specific user function is not needed.
        * Improvements to the GUI text subscripting in the relaxation dispersion analysis frame.
        * Removed the temporary relaxation dispersion SVG graphic for the GUI analysis.
        * Redesign of the graphic for the relaxation dispersion analysis.  This is a modification of the r1.svg graphic to show roughly the graphic as in "Protein NMR Spectroscopy, Principles and Practice" by Cavanagh, Fairbrother, Palmer and Skelton.
        * Editing of the relaxation dispersion analysis graphic.
        * Added the relaxation dispersion graphic to all of the dispersion GUI user functions missing a graphic.
        * Redesign of the relaxation dispersion models in the relax_disp.select_model user function front-end.  The models have been renamed and better defined based on the experiment type (CPMG or R1rho).
        * The relaxation dispersion scaling matrix assembly now uses lib.mathematics.round_to_next_order().  This allows the printed out I0 values for the optimisation of the exponential curves to be easier to scale back to the real value.
        * The Relax_disp.test_hansen_cpmg_data_fast_2site system test now uses the R2eff model.  The equivalent slow exchange system test also uses the model.  This model will be used to find the R2eff values from the fixed relaxation time period data.
        * Fix for some RelaxError printouts in the relaxation dispersion specific code.
        * The relaxation dispersion class variables for the experiment types are now used for all comparisons.  This should avoid random bugs.
        * Fix for the calculation part of the relaxation dispersion auto-analysis.  This is for the fixed relaxation period data types.
        * The 2D Grace plots of the exponential curves are now skipped for the fixed relaxation period data types.  This is in the relaxation dispersion auto-analysis.
        * Started to implement the relaxation dispersion analysis specific calculate() method.  This will be used to calculate the R2eff/R1rho values for the fixed relaxation time period data types and is equivalent to Sebastien Morin's relax_disp.calc_r2eff user function which was deleted (see http://thread.gmane.org/gmane.science.nmr.relax.scm/17336).
        * Converted the specific_analyses.relax_disp module into its own package.  This is to allow the code to be broken up into separate modules to simplify the analysis.
        * Shifted out all of the variables and dispersion data specific code into separate modules.  The dispersion data private methods have been converted into functions of the specific_analyses.relax_disp.disp_data module.  The package variables have also been shifted into the specific_analyses.relax_disp.variables module to avoid circular imports.
        * Alphabetical ordering of the functions of the specific_analyses.relax_disp.disp_data module.
        * Created the specific_analyses.relax_disp.disp_data.loop_all_data() function.  This is to loop over all possible base relaxation dispersion data (spectrometer frequencies then dispersion points).
        * Updates for the dispersion user functions for the changes in specific_fns.relax_disp.
        * Typo fix in the new loop_all_data() function.
        * Created the lib.dispersion.calc_two_point_r2eff() function.  This is for calculating the R2eff/R1rho value for the fixed relaxation time data.
        * Improvements to the specific_analysis.relax_disp.disp_data module.  The function loop_all_data() has been expanded to include the relaxation time period into the loop.  The functions return_intensity() and return_key() have been added to return peak intensities and the key corresponding to the data returned by loop_all_data().
        * Fixes for some latent bugs in the specific_analyses.relax_disp.disp_data module.  The checks for the CPMG-data type in a number of functions now uses the CPMG_EXP list instead of fixed strings.
        * Completed the relaxation dispersion calculate() method.  This allows the R2eff/R1rho values to be calculated for the fixed relaxation time period experiments through the calc user function.
        * Created a script for running a full relaxation dispersion analysis on Flemming Hansen's data.  This is located in the shared data directories and is not part of the test suite as a full analysis will take far too long.
        * Updated the models in the script for the full relaxation dispersion analysis of Hansen's data.
        * Updated the backend of the relax_disp.select_model to handle the new model names.
        * Spun out a number of dispersion methods into the new specific_analyses.relax_disp.parameters module.  This is a module of functions relating to the parameters of the relaxation dispersion models.
        * More spacing before the sectioning printouts in the relaxation dispersion auto-analysis.
        * Modified the printouts of the relax_disp.select_model user function.
        * Fix for the relaxation dispersion auto-analysis.  The data pipes created for each model optimised are now switched to prior to any operations on the pipe.
        * Changed the phi_ex parameter in the LM63 model back to rex.
        * Changed the Grace string for the rex parameter to be phi_ex.
        * Converted all of the specific_analyses.relax_disp.parameters module to handle different models.  The R2eff and I0 parameters are now only part of the 'R2eff' model and all other standard parameters belong to all of the other models.
        * Shifted all of the constant relaxation dispersion variables into the specific module.  All of the dispersion code now uses the variables of specific_analyses.relax_disp.variables.
        * Renamed the lib.dispersion.equations.fast_2site() function to r2eff_LM63().  The number of relaxation times has also been replaced by the number of dispersion points.
        * Added the return_cpmg_frqs() and return_spin_lock_nu1() functions to specific_analyses.relax_disp.disp_data.
        * Updates to the relaxation dispersion auto-analysis.  The Grace plots created are now more dependent on the current model, so that dispersion curves are only created for the 'R2eff' model.  The specific_analyses.relax_disp.variables module is now also being used.
        * Started to redesign the relaxation dispersion target function class.  The input data is now expected to be R2eff/R1rho data and all mentions of exponential curves have been eliminated.  The func_exp_fit() target function has been deleted as it is not used - as now the _minimise_r2eff() method in the dispersion specific analysis class is used instead.  And the func_fast_2site() target function has been renamed to func_LM63().
        * Redesigned the optimisation code of the dispersion analysis specific class for the new target functions.  This includes the assembling of R2eff/R1rho values instead of peak heights, and a number of small fixes.
        * Shifted the LM63 dispersion model functions into the new lib.dispersion.lm63 module.
        * The reference spectrum is now not included when counting the number of dispersion points.
        * Fix for the lib.dispersion.lm63 module and parameters of zero are now gracefully handled.
        * Fixes for the func_LM63() dispersion target function.
        * Shifted the R2eff/R1rho value and error assembly into specific_analyses.relax_disp.disp_data.  This is in the new return_r2eff_arrays() function.  The code has also been debugged and made functional.
        * Added support for handling missing data in the relaxation dispersion analysis.  This support was mentioned in the post http://thread.gmane.org/gmane.science.nmr.relax.devel/3835.
        * Added a FIXME to a comment about the hardcoded Bootstrap number for relaxation dispersion.
        * Started to add support for Monte Carlo simulations for the relaxation dispersion models.  This is for all models except 'R2eff'.  The changes are extensive but incomplete.  The new functions disp_point_key_from_index() and disp_point_index_from_key() have been added to the specific_analyses.relax_disp.disp_data module, but the disp_point_index_from_key() function still needs work.  The _back_calc() method of the specific_analyses.relax_disp.Relax_disp class has been redesigned, as well as base_data_loop() method and all methods which depend on it.
        * Updated the relaxation dispersion system tests of the Hansen CPMG data for the new models.  The models are now 'LM63' and 'CR72', and the tests have been renamed to Relax_disp.test_hansen_cpmg_data_LM63 and Relax_disp.test_hansen_cpmg_data_CR72.
        * Update of the specific_analyses.relax_disp package docstring.
        * Fix for the linear constraints setup of the 'R2eff' relaxation dispersion model.  There are no constraints, so the specific_analyses.relax_disp.parameters.linear_constraints() function now returns A and b values of None.
        * Basic fix for the _back_calc_r2eff() relaxation dispersion method.  A variable was misnamed.
        * Major redesign of the relaxation dispersion data model in the relax data store.  The data model now revolves around the three concepts of the spectrometer frequency, the dispersion points, and the relaxation times.  Peak intensity data is now handled through averaging using the new specific_analyses.relax_disp.disp_data.average_intensity() function.  R2eff/R1rho values are now referenced by a key generated from the spectrometer frequency and nu_CPMG frequency or nu1 spin-lock field strength.  All of the specific_analyses.relax_disp package has been standardised around these concepts.  This simplifies all of the modules of the package and removes a large number of latent bugs.
        * A number of fixes to partly enable Monte Carlo simulations for the non 'R2eff' dispersion models.
        * Finally Monte Carlo simulations for the relaxation dispersion models now work.  This was a simple fix for the specific_analyses.relax_disp.parameters.param_index_to_param_info() function.
        * Created truncated data files of the Hansen CPMG data.  This consists of residues 70 and 71 and will be used to massively speed up the system tests.
        * The truncated Hansen CPMG data is now in the form of Sparky peak lists.
        * Now all of the Hansen CPMG data is present as truncated Sparky peak lists.
        * Speedup for the relaxation dispersion system tests which use Flemming Hansen's CPMG data.  The system test script now reads the truncated data files (of only residues 70 and 71) to minimise the time required to read the data and store it in the relax data store.
        * Added a script to the test suite shared data for analysing the truncated Hansen CPMG data.
        * Fixes for the LM63 dispersion CPMG model.  The 'r2' model parameter is now an array as there is one R2 value per magnetic field strength.  And the 'rex' parameter has been renamed to 'phi_ex' and is scaled quadratically with the field strength within the optimisation target function.
        * Fix for the setup of the relaxation dispersion GUI analysis.  The base method add_execute_relax() has been renamed to add_execute_analysis().
        * Added support for interfacing with Art Palmer's CPMGFit program.  The two new user functions relax_disp.cpmgfit_input and relax_disp.cpmgfit_execute have been created to interface with CPMGFit.  The first creates the per spin system CPMGFit input files as well as a batch script for executing CPMGFit with all the input files.  The second bypasses the batch script and allows CPMGFit to be executed from within relax.  This mimics the palmer and dasha user functions.  The back end code is in the new specific_analyses.relax_disp.cpmgfit module.
        * Created the Relax_disp.test_hansen_cpmgfit_input system test.  This is for checking the operation of the relax_disp.cpmgfit_input user function conversion of Flemming Hansen's CPMG R2eff values into input files for CPMGFit.  A relax state file containing the results of an analysis of an 'R2eff' model analysis of the truncated data has been added to the test suite data to speed up the test and to check the loading of dispersion state files.
        * Created a directory for the results of the CPMGFit program using Hansen's truncated CPMG data.  The script 'cpmgfit.py' has been added to create the input files for CPMGFit and execute the program.  The input and batch files have been added to the repository as well.
        * Added the results from NESSY of the analysis of Flemming Hansen's truncated CPMG data.  This is only for the truncated data of residues 70 and 71.  All files, except for the PNG graphics, have been added to the repository.  The 'summary' file has been created to hold the data from NESSY's summary tab, as this is not stored in the NESSY saved state and is permanently lost after closing NESSY.
        * A dispersion saved state from the prompt or script UI can now be associated with a GUI analysis.
        * Created the Relax_disp.test_hansen_trunc_data GUI test for checking the GUI dispersion auto-analysis.  This checks the full operation of the relaxation dispersion GUI analysis, without checking the final results (to be added later).
        * Fixes for the change to the new spectrometer.frequency user function and associated data structures.
        * Removed the preview button from the file selection GUI element of the CPMGFit user functions.  These are the relax_disp.cpmgfit_execute and relax_disp.cpmgfit_input user functions.
        * The relaxation dispersion specific code now uses the changes of the spectrometer.frequency user function.  This simplifies the handling of magnetic field strength data.
        * More fixes to the relax_disp branch for the changes of the spectrometer.frequency user function.
        * Changes to the CPMGFit input files due to the new spectrometer.frequency user function.
        * The relax_disp.cpmgfit_execute user function now correctly calls CPMGFit.  The -grid command line option has been added and the output for each spin is sent to a special output file.
        * Updated the input files and added the output files for the CPMGFit program with Hansen's CPMG data.  This is for the data truncated to residues 70 and 71.
        * Fixes for the relax_disp branch for the spectrometer.frequency user function changes.
        * Fix for the Relax_disp.test_hansen_cpmgfit_input system test.  This is for the recent spectrometer.frequency user function changes.
        * The specific_analyses.relax_disp.disp_data.loop_frq() function can now handle missing data.  This allows the loop to yield a single value of None when the spectrometer information has not been loaded and enables R1rho analyses at a single field strength.
        * Fix for the LM63 dispersion model target function - the scaled Phi_ex value is now used for the R2.
        * Fixes for the relaxation dispersion auto-analysis for the LM63 model.  The Rex parameter is now the phi_ex parameter.
        * Added printouts of the optimised parameters to the Relax_disp.test_hansen_cpmg_data_LM63 system test.  This includes the conversion to the equivalent CPMGFit parameters.
        * Massively increased the precision of the R2eff error analysis.  The hard-coded simulation number variable is now set to 100000.  This appears to be necessary for reliably reproducing results in the subsequent dispersion models.
        * Created the specific_analyses.relax_disp.disp_data.spin_has_frq_data() function.  This is for determining if a spin has peak intensity for the given spectrometer field strength.
        * Updates some scripts for the spectrometer.frequency user function change.
        * Created a script to calculate the R2eff rate errors extremely precisely for Hansen's CPMG data.  This uses 1 million Bootstrap simulations for calculating the errors.  The 'r2eff_values.bz2' is saved after deleting the spin specific r2eff_sim structures so that the file drops from 388 Mb in size to 7.3 kb.
        * The CPMGFit script for Hansen's CPMG data now starts with the high precision error r2eff_values.bz2 file.  This ensures consistency between comparisons between relax, NESSY, CPMGFit, etc.
        * Removed the '_trunc' part of the nessy_results directory from the NESSY final save file.
        * The relaxation dispersion loop_point() function can now return the reference point.  This is enabled via the skip_ref argument.
        * Created the relax_disp.nessy_input user function front and backends.  This user function takes the data in the relax data store and creates a NESSY save file to be opened within NESSY.  The backend is the new specific_analyses.relax_disp.nessy module.  For the GUI frontend, graphics for icons and the wizard have been taken from the NESSY repository file pics/nessy_new.png@r1088 in the trunk.
        * A script has been added to create the NESSY input for Flemming Hansen's CPMG data.
        * Updated the NESSY results for Flemming Hansen's CPMG data for the R2eff values with high precision errors.  A file containing the log or printouts from NESSY has been added for reference.
        * Updated the NESSY log from the Hansen CPMG data of residue 70 to remove the NESSY errors.  These were removed with the commit r1090 to the NESSY trunk.
        * Split up the r2eff_values.bz2 save file into the results files for each data pipe.  This is for Flemming Hansen's CPMG data truncated to residues 70 and 71.  This is to simplify the system tests which use this data.
        * Large simplification of the Relax_disp system tests using Hansen's CPMG data.  Instead of calculating the R2eff values in the test, these are read from the high error precision results files in test_suite/shared_data/dispersion/Hansen.  This allows the model parameters to be consistently found and to be identical between different runs of the test.
        * Added a file which compares the results for the LM63 model with Hansen's CPMG data between all programs.  This currently includes relax, NESSY and CPMGFit.
        * Added a printout to the specific_analyses.relax_disp.cpmgfit.translate_model() function.
        * The dispersion system test script for Hansen's CPMG data can now run stand-alone.
        * The log barrier constraint algorithm is now used for the relaxation dispersion optimisation.  This is to allow constraints in the absence of gradient target functions.  The constraints have been turned on by default in the auto-analysis.
        * Changed the dispersion GUI tab to use the model names from specific_analyses.relax_disp.variables.
        * The spectrum wizard now uses the spectrometer.frequency user function rather than frq.set.  The frq.set user function is now called spectrometer.frequency.
        * An upper limit of 200 rad/s has been added to the linear constraints for the R2 dispersion parameters.
        * Fixes for the checking in the Relax_disp.test_hansen_cpmgfit_input system test.
        * The relaxation dispersion auto-analysis now calls the relax_disp.plot_disp_curves user function.  This user function is not implemented yet, but will be used to create plots of the dispersion curves.
        * Implemented a basic graph for the relax_disp.plot_disp_curves user function.  This simply plots out the nu_CPMG value or spin-lock field verses the R2eff/R1rho values from the experiment.  The graph of the back calculated R2eff/R1rho values from the model fit is still to be added.
        * Fix for the linear constraints for the 'R2eff' model.  The A and b matrices are no longer set to None, as this kills the auto-analysis or any analysis when constraints are turned on.  Now the constraints 0 <= R2eff <= 200 and I0 >= 0 are used.
        * Fixes for the peak intensity loading wizard for the frq.set to spectrometer.frequency user function change.
        * Fixes for the backend of the relax_disp.plot_exp_curves user function.  This code needed to be updated for the major changes in the relax_disp branch.
        * Fixes for the checks in the Relax_disp.test_exp_fit system test.  The r2eff and i0 spin data structure keys are now strings.
        * Two class variables have been added to the dispersion auto-analysis for fast optimisation.  This includes variables for the function tolerance and maximum number of iterations, and matches those of the model-free auto-analysis of the dauvergne_protocol module.  These will be used to speed up the test suite.
        * Speed up of the system tests using Flemming Hansen's CPMG data.  The grid search increments, function tolerance and maximum number of iterations have all been made looser.
        * Added parameter checks to the Relax_disp.test_hansen_cpmg_data_LM63 system test.
        * Fix for the phi_ex dispersion parameter scaling - the scaling was in the wrong direction.
        * Added a directory of relax results for the truncated high-precision Hansen CPMG R2eff values.  This uses the base_pipe.bz2 and r2eff_pipe.bz2 files with the high-precision R2eff errors, and hence can be compared to the NESSY and CPMGFit results.
        * Added the residue :71 results to the lm63_comparison file.  This is a summary of the optimisation results using the high-precision R2eff error results for the different dispersion softwares.
        * Changes to the dispersion auto-analysis write_results() method.  This is to output more of the dispersion parameters to text files and 2D grace plots.
        * Created a directory and script in preparation for the relax_disp.sherekhan_input user function.
        * Created the relax_disp.sherekhan_input user function.  This includes an icon for the GUI, and the full front and backends.
        * Added a wizard graphic for the relax_disp.sherekhan_input user function.
        * Shifted the core of the model_loop() dispersion method into its own function.  The new function specific_analyses.relax_disp.disp_data.loop_cluster() can now be used by other parts of relax.  The model_loop() method now yields the data that loop_cluster() yields.
        * Redesign of the relax_disp.sherekhan_input user function to handle spin clustering.
        * Added the ShereKhan results for the high-precision R2eff data for Hansen's CPMG data.
        * Converted the readme file for Flemming Hansen's CPMG data directory to uppercase.
        * Updated the LM63 model comparison table.
        * Modified the dispersion calculate() method for the R2eff values to use the analytic equation.  For the R2eff/R1rho values calculated for the fixed time period dispersion experiments via the calc user function, the very slow and tedious bootstrapping approach has been replaced by the very quick direct error calculation.  The two techniques produce the same results as the bootstrap simulation number approaches infinity.
        * Bug fix for the peak intensity error analysis in the dispersion auto-analysis.  Now the error analysis is split based on the magnetic field strength.  Previously the analysis was a mess with the split often being individual spectra.
        * The proper experiment type is now set for the Relax_disp.test_hansen_trunc_data GUI test.
        * Updated the relax_disp.exp_type user function to be more specific an include more experiment types.
        * Updated the specific_analyses.relax_disp.variables module for the relax_disp.exp_type changes.
        * The relax_disp.relax_time page is now always shown in the peak intensity wizard for the dispersion GUI.  This number is needed for the fixed time period experiments as well to calculated the R2eff/R1rho values and errors.
        * Fix for the dispersion auto-analysis write_results() method.  The i0 parameter text file and 2D Grace file are now only produced for the 'R2eff' model with the exponential curve base data types.
        * Simplified the Relax_disp.test_hansen_trunc_data GUI test.  The 'CR72' model is now deactivated and the grid search sized decreased from the default of 21 to 4.
        * Big speed ups of the Relax_disp.test_hansen_trunc_data GUI test.  The optimisation function tolerance and maximum number of iterations are now set to the same low precision as the system tests.  This involves adding hidden variables to the dispersion GUI analysis.
        * Removed the data pipe name check from the Relax_disp.test_hansen_trunc_data GUI test.  This makes no sense as this analysis generates a data pipe for each model (similar to the model-free analysis).
        * Fix for the relax_disp.exp_type call in the Relax_disp.test_exp_fit system test script.
        * Better formatting of the references for the dispersion analytic model equations.
        * Updated the relax_disp.select_model user function frontend for the CR72 dispersion model.  This includes fixing the parameter list and the equations presented to the user.
        * Removed the commented out junk model code from the relax_disp.select_model user function frontend.
        * Added the CR72 model equations to the relax library.  This is for the Carver and Richards 1972 2-site exchange model covering all time scales.
        * Initial implementation of the CR72 target function.
        * Import fix for the lib.dispersion.cr72 module.
        * Fixes to the specific_analyses.relax_disp modules to add support for the CR72 dispersion model.  The parameters for the CR72 model are now both correct and correctly handled.
        * Fix for the spin container list of parameters for the CR72 model.
        * The CR72 dispersion model equations are now more robust against math domain errors.  This is for the trigonometric functions which cannot handle certain input values.
        * Renamed the file for comparing different dispersion software with Flemming Hansen's CPMG data.
        * Added the initial results of the CR72 model in relax for Flemming Hansen's truncated CPMG data.
        * Simplified the pA >= pB constraint in the dispersion linear_constraints() function.
        * Fixes for the dispersion linear_constraints() function.  The indices were being incorrectly handled - the i and k index should be one and the same parameter index.
        * Added support for the 'CR72' or 'Full_CPMG' model to the relax_disp.cpmgfit_input user function.
        * Added the results for the CR72 model optimisation in CPMGFit using Flemming Hansen's truncated CPMG data.
        * Added the CR72 model results to the software comparison document for Hansen's CPMG data.
        * Improvements for the phi_ex and dw relaxation dispersion model parameters.  These are now stored with the units of ppm^2 and ppm respectively.  The conversion to (rad/s)^2 and rad/s units respectively now is spin specific, allowing mixed spin types (1H, 13C, 15N, etc.) to be analysed simultaneously.
        * Updated the relax results for Hansen's CPMG data for the recent phi_ex and dw changes.
        * Fixes for the CPMGFit results in the software comparison table for Hansen's CPMG data.
        * Fix for the grid search setup for the pA dispersion parameter.  As pA > pB, then the region from 0.0 to 0.5 does not need to be searched.
        * The back calculated R2eff values are now stored for dispersion analysis after minimisation.
        * Fix for the CR72 model equation in lib.dispersion.cr72.r2eff_CR72().  The eta scaling factor was incorrect.
        * Updated the relax results for the truncated CPMG data from Flemming Hansen.  This is for the recent fixes of the CR72 model equations.  Now relax produces identical results to ShereKhan for the LM63 and CR72 models.
        * Created a directory for holding relaxation dispersion sample scripts.
        * Added the model for no chemical exchange relaxation to the dispersion analysis.
        * Updated the NESSY log file for its improved printouts.  These printouts allow the R20 values to be accessed.
        * Another update of the NESSY log for the improved and more detailed printouts.
        * And again, another update of the NESSY log.
        * Added the relax results for the 'No Rex' model.
        * Updated the software comparison tables for the model of no exchange.  This is for Flemming Hansen's truncated CPMG data.
        * Fix for the Relax_disp system tests using Flemming Hansen's truncated CPMG data.  The nuclear isotope is now being set.
        * Increased the grid size for the hansen_data.py system test script.  This is needed to allow the parameters to be reliably found.
        * Fixes for the checks and printouts of the Relax_disp.test_hansen_cpmg_data_LM63 system test.
        * Updated some NESSY results in the software comparison document.
        * Fix for the CPMGFit batch file creation.  The command line options are now correct and output is redirected to output files.
        * Updated the CPMGFit batch file.
        * Created the Relax_disp.test_hansen_cpmg_data_auto_analysis system test.  This is designed to fully test the dispersion auto-analysis for CPMG-type data.
        * Fix for the Relax_disp.test_hansen_cpmgfit_input system test.  This is for the recent CPMGFit batch file changes.
        * Better checking of optimisation in the Relax_disp system tests.  This affects the Relax_disp.test_hansen_cpmg_data_LM63 and Relax_disp.test_hansen_cpmg_data_CR72 system tests.  Instead of using the auto-analysis, these tests now set the initial parameters close to the minimum, skip the grid search, and perform a low precision optimisation to reach the minimum.  This is important because the low quality grid search and optimisation can not always find the real minimum.
        * Created the lib.dispersion.equations.calc_two_point_r2eff_err() function.  This complements the lib.dispersion.equations.calc_two_point_r2eff() function and is used by the dispersion calculate() method to abstract the mathematics.
        * Updated the relax_disp.select_model user function docstring for the R2eff error analysis.  This properly describes how the R2eff/R1rho errors are calculated for the fixed relaxation time period experiments.
        * Docstring fixes for the lib.dispersion.equations module.
        * Expanded the number of model list variables in specific_analyses.relax_disp.variables.  This is to include lists which are specific to CPMG-type and R1rho-type experiments.
        * Added the new 'M61' model to the specific_analyses.relax_disp.variables module.  This is the Meiboom 1961 model for 2-site fast exchange for R1rho-type experiments.
        * Added the M61 model to the relax_disp.select_model user function frontend.  This is the Meiboom 1961 model for 2-site fast exchange for R1rho-type experiments.
        * Added the M61 model equations to the relax library.  This is for the Meiboom 1961 2-site fast exchange model for R1rho-type experiments.
        * Created the M61 2-site fast exchange dispersion model target function.  This is for the Meiboom 1961 model for 2-site fast exchange for R1rho-type experiments.  The code for the func_M61() method was copied without modification from the func_LM63() method.
        * Added support for the R1rho-type experiments to the relaxation dispersion analysis in the GUI.  This involves using a different model list for these experiments compared to the CPMG-type experiments.
        * Updated the relaxation dispersion GUI to handle the current set of experiment types.
        * Fix for the Relax_disp.test_hansen_cpmg_data_auto_analysis system test.  The correct model list is now being used - the R1rho-type experiments should not be included.
        * Fix for the missing import of the lib.dispersion.equations.calc_two_point_r2eff_err() function.
        * Added support for the M61 model to the relax_disp.select_model user function back end.  This is for the Meiboom 1961 2-site fast exchange model for R1rho-type experiments.
        * Another fix for the Relax_disp.test_hansen_cpmg_data_auto_analysis system test.  The correct model list is finally being used.
        * Fix for the lib.dispersion.equations.calc_two_point_r2eff_err() function.  The variables were incorrectly named.
        * Added support for setting the spin isotope information in the dispersion GUI.  A new Text_ctrl element has been added just after the spin system GUI element.  This displays a list of all the spin isotopes currently defined and is updated after every GUI user function call.  The button of the element launches the spin.isotope user function.  The spin isotope information is now checked for prior to executing the GUI analysis and added to the missing list to present to the user when blocking the execution of the analysis.  The dispersion GUI test has been updated to use this new element.
        * Added support for model selection to the relaxation dispersion specific analysis package.  This involved redesigning the model_loop() method.  Instead of yielding both the spin containers and the spin IDs, now only spin IDs are yielded.  This is important as the model loop is used independently of the data pipes.  Hence the spin containers cannot be yielded as multiple pipes are compared within the model loop.  The auxiliary method _spin_ids_to_containers(spin_ids) has been added to obtain the list of spin containers from the list of spin IDs.  To support model selection, the methods duplicate_data(), model_desc() and model_statistics() have been added, and model_type() aliased to the common _model_type_local() method.
        * Expanded the relaxation dispersion auto-analysis.  A final step of model selection has been added to select between the different models for each spin cluster.  This is stored in the 'final' data pipe, and its results output via the write_results() method.
        * The model selection technique can now be changed in the dispersion auto-analysis.
        * The error when selecting a non-existent model using relax_disp.select_model is now more informative.
        * Model selection in the dispersion auto-analysis is only performed if 2 or more models are present.  Excluding the 'R2eff' model, if only 0 or 1 models are optimised, then model selection is skipped and a warning is given.  This avoids tracebacks in the model_selection user function.
        * Added some synthetic on-resonance R1rho data to the test suite.  This is in the form of Sparky peak list files containing two spin systems.
        * Expanded the synthetic on-resonance R1rho test suite data.  The data now consists of a full set of dispersion curves for the M61 model.
        * Added a reference to the synthetic on-resonance R1rho test suite data.  The first ncyc1 data point now has a relaxation time period of zero, hence it can be used as the reference for a fixed time period experiment.
        * The reference spectra can now be set in the relax_disp.spin_lock_field user function.  By setting the field to None, the reference spectrum for a fixed relaxation time period experiment type can now be specified.  This mimics the behaviour of the relax_disp.cpmg_frq user function.
        * Added some error checking to the specific_analyses.relax_disp.disp_data.average_intensity() function.  This is for better feedback to the user in case they have not set up their data correctly.
        * The relax_disp.select_model user function now operates without the spectrometer frequency being set.  The special loop_frq() function is now used as this can handle missing spectrometer frequency information.
        * The find_intensity_keys() function can now handle the reference spectrum.  This function in the specific_analyses.relax_disp.disp_data module was failing if the relaxation time period for the reference spectrum was missing.  Time information shouldn't be needed for the reference, so is no longer checked.
        * The dispersion specific optimisation methods can now handle missing spectrometer information.
        * The return_index_from_frq() now handles missing frequency information.  This is in the specific_analyses.relax_disp.disp_data module.
        * Better support for missing frequency information in the specific_analyses.relax_disp.disp_data module.  This is in the return_index_from_frq() function which now returns an index of 0, and in return_r2eff_arrays() which skips calculating the frequency information.
        * The dispersion disassemble_param_vector() function now handles missing spectrometer information.  The loop_frq() function replaces direct looping over cdp.spectrometer_frq_count.
        * Variable renaming in the lib.dispersion.m61 module.  The variable names are now more suited to R1rho-type data, rather than CPMG-type data.
        * Fix for the M61 model target function.  The spin-lock fields need to be used, not the CPMG frequencies.
        * Created the Relax_disp.test_r1rho_on_res_fixed_time_m61 system test.  This checks the R1rho-type experiment with a fixed relaxation time period using the 'R2eff' and 'M61' models.  It uses the auto-analysis for this, and the 'r1rho_on_res' synthetic relaxation data.
        * Created the Relax_disp.test_r1rho_on_res_exponential_m61 system test.  This is identical to the Relax_disp.test_r1rho_on_res_fixed_time_m61 system test except that the full exponential curves are used rather than the 2-point fixed time approach.
        * Python 3 fixes for the relaxation dispersion parameter Grace strings.
        * Python 3 fixes for the modules of the specific_analyses.relax_disp package.
        * Fix for a bug preventing the optimisation of the dispersion models.
        * Fixes for the file permission setting on the CMPGFit batch script.  The correct file mode is now set for Unix-based systems.
        * Python 3 fixes for the relax_disp.cpmg_frq and relax_disp.spin_lock_field user functions.  The sorting of lists with None is not supported by Python 3, so this has to be carefully handled.
        * Removed the grid search size check from the dispersion _grid_search_setup() method.  This is performed by minfx anyway, and the code was incompatible with Python 3.
        * Fix for the Relax_disp.test_hansen_cpmgfit_input system test.  The frequencies for the CPMGFit input files now are only written to 10 places.  This is for Python 2 vs. 3 consistency.
        * Python 3 fix for the relax_disp.cluster user function.
        * Fix for the Grace plots created by the relax_disp.plot_disp_curves user function.  The data set from each frequency is now a separate set in the G0 graph.
        * Improvements to the relax_disp.plot_disp_curves user function.  The back-calculated R2eff/R1rho values are now included in the plot as separate sets.  In addition, the residuals have also been added to allow for a visual statistical comparison.
        * More improvements to the relax_disp.plot_disp_curves user function.  The data sets now have labels, and the residuals have errors set to those of the R2eff/R1rho data.
        * More improvements to the relax_disp.plot_disp_curves user function.  The graph axes maximum is now set to a reasonable value for the given data.
        * Added the 'No Rex' model to the relax script for optimising Flemming Hansen's CPMG data.
        * The isotope type is now set in the relax script for optimising Flemming Hansen's CPMG data.
        * Shifted the _spin_ids_to_containers() method to the disp_data.spin_ids_to_containers() function.
        * Fix for the relax_disp.sherekhan_input user function.  The loop_cluster() function no longer returns spin containers.
        * Fix for the r2eff_calc.py script for calculating R2eff values from Flemming Hansen's CPMG data.
        * Added a check to the dispersion specific minimise() function for the spectrometer field strength.  This is essential in all dispersion models to convert between ppm and rad/s units, or ppm^2 and (rad/s)^2 for the phi_ex parameter.
        * The r1rho_on_res_m61.py dispersion system test script now sets the spectrometer frequency information.
        * Removed cdp.model as this makes no sense - a different model can be used per spin cluster.  Now the variable cdp.model_type is used to identify the 'R2eff' model.  For all other dispersion models this variable is set to 'Disp'.
        * Added a log file for the data generation script for the r1rho_on_res dispersion data.
        * Fixes for the parameter checks in the system tests for the r1rho_on_res synthetic data.  This includes both the Relax_disp.test_r1rho_on_res_fixed_time_m61 and Relax_disp.test_r1rho_on_res_exponential_m61 tests.
        * Fixes for the lib.dispersion.m61.r2eff_M61() function.
        * Increased the precision of the Sparky peak lists for the r1rho_on_res dispersion test data.  All peak intensities are now 1000 bigger.  As the values are integers in the Sparky files, the previous values were too truncated for the system tests to properly optimise and find the original parameters.
        * Speed up of the r1rho_on_res_m61.py system test script.  The optimisation precision is now much lower.  And the peak intensity errors now have been scaled by 1000 just as the base data was in the previous commit.
        * Improvements for the parameter checks in the system tests for the r1rho_on_res synthetic data.  This includes both the Relax_disp.test_r1rho_on_res_fixed_time_m61 and Relax_disp.test_r1rho_on_res_exponential_m61 tests.
        * Clustering was accidentally turned off in the r1rho_on_res_m61.py system test script.
        * Created the specific_analyses.relax_disp.disp_data.count_frq() function.  This is for determining the number of spectrometer frequencies present, even if not data has been defined.
        * Loosened the checks for the Relax_disp.test_hansen_cpmg_data_CR72 system test.
        * Completely redesigned how parameters are handled in the relaxation dispersion analyses.  The key concept is that everything revolves around the new loop_parameter() function.  This is a generator function which loops over the parameters of a given cluster, yielding all the information required to access the parameter.  The other functions of the parameters module use loop_parameter() to sequentially handle each parameter.  This allows for huge simplifications of these functions.
        * Fixes for the Relax_disp.test_hansen_cpmg_data_auto_analysis system test.  One of the models for one spin now optimises completely and the checks have all been loosened.
        * Fixes for the dispersion specific model_statistics() method.  This now handles spin clustering correctly.
        * Updated the results of relax's analysis of the truncated CPMG data from Flemming Hansen.
        * Updates for the model variable docstrings.
        * Added the 'M61 skew' model to the specific_analyses.relax_disp.variables module.  This is the Meiboom 1961 model for skewed populations (pA >> pB).  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'M61 skew' model to the relax_disp.select_model user function frontend.  This is the Meiboom 1961 model for skewed populations (pA >> pB).  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Fixes for the spacing after some equations in the relax_disp.select_model docstring.
        * Simplifications and comment fixes in the lib.dispersion.m61.r2eff_m61() function.
        * Renamed the lib.dispersion.m61.r2eff_M61() function to r1rho_M61().
        * Added the M61 skew model equations to the relax library.  This is the Meiboom 1961 on-resonance 2-site model for skewed populations (pA >> pB).  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Created the M61 skew model target function.  This is the Meiboom 1961 on-resonance 2-site model for skewed populations (pA >> pB).  This commit follows step 4 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the skewed condition (pA >> pB) to the specific_analyses.relax_disp.parameters module.  This is currently done by constraining pA to be greater than 0.85.
        * Added support for the M61 skew model to the relax_disp.select_model user function back end.  This is the Meiboom 1961 on-resonance 2-site model for skewed populations (pA >> pB).  This commit follows step 6 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Big speeds ups of the lib.dispersion modules.  Many replicated calculations have been shifted outside of the dispersion point loop, as these only need to be calculated once per function call.  Some if statements have consequently been simplified.
        * Renamed the lib.dispersion.equations module to lib.dispersion.two_point.
        * Renamed the r1rho_on_res dispersion test suite data directory to r1rho_on_res_m61.
        * Created test data for the 'M61 skew' R1rho model.  This is the Meiboom 1961 on-resonance 2-site model for skewed populations (pA >> pB).  This commit follows step 7 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Created the Relax_disp.test_r1rho_on_res_fixed_time_m61b system test.  This is for the Meiboom 1961 on-resonance 2-site model for skewed populations (pA >> pB).  This commit follows step 7 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Small simplification of the lib.dispersion.m61b module.
        * Fix for the specific_analyses.relax_disp.disp_data.return_value_from_frq_index() function.  This cdp.spectrometer_frq_list list structure rather than the cdp.spectrometer_frq dictionary should be used.
        * Added a printout at the end of the optimisation of the final dispersion parameter values.
        * Modified the optimisation printout for better formatting.
        * Increased the precision of the hansen_data.py relaxation dispersion system test script.  This actually speeds up the test, as the Monte Carlo simulations are significantly speed up when the CR72 model optimises to the solution.
        * Updates for the pA dispersion parameter optimisation constraints.  The parameter is now limited to be between pB and 1.  In the case of the limit pA >> pB, then instead the constraint is between 0.85 and 1.
        * Updated the Relax_disp system tests.  This is for the recent precision change and constraint changes.
        * Fixes for the grid search for the 'M61 skew' dispersion model.  The pA parameter search is now between 0.85 and 1.
        * Fixes for the func_M61b() dispersion target function.  This is the Meiboom 1961 on-resonance 2-site model for skewed populations (pA >> pB).
        * Small changes to the r1rho_on_res_m61b dispersion test data.  One R20 rate has been increased.
        * Completed the lib.dispersion.m61.r1rho_M61() function.  Now the R1 relaxation rate and rotating frame tilt angle are correctly handled.  This is not used in the target functions as support for the R1 and offset is not yet implemented.
        * Added the 'DPL94' model to the specific_analyses.relax_disp.variables module.  This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'DPL94' model to the relax_disp.select_model user function frontend.  This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Updates to the Relax_disp.test_r1rho_on_res_fixed_time_m61b system test.
        * Added the DPL94 model equations to the relax library.  This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Created the DPL94 model target function.  This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.  This commit follows step 4 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the DPL94 model to the relax_disp.select_model user function back end.  This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.  This commit follows step 6 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Created the Relax_disp.test_r1rho_on_res_fixed_time_dpl94 system test.  This is the David, Perlman and London 1994 R1rho 2-site fast exchange model.  This commit follows step 7 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'IT99' model to the specific_analyses.relax_disp.variables module.  This is the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'IT99' model to the relax_disp.select_model user function frontend.  This is the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Updated the model lists of the dispersion analyses GUI element.  This adds the IT99 CPMG-type model and the DPL94 and M61B R1rho-type models.
        * Fixes for the IT99 model description in the relax_disp.select_model user function.  This is the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the IT99 model equations to the relax library.  This is the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the it99 module to the lib.dispersion package __all__ list.  This is the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Created the IT99 model target function.  This is the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 4 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Fix for the lib.dispersion.it99 module.  This is the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the support for the pA.dw^2 parameter 'padw2' to the dispersion specific analysis.  This is needed for the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 5 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the IT99 model to the relax_disp.select_model user function back end.  This is the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 6 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the support for the tex parameter (tex = 1/(2kex)) to the dispersion specific analysis.  This is needed for the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 5 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the IT99 model to the relax_disp.cpmgfit_input user function.  This is the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.
        * Fix for the relax_disp.cpmgfit_input user function for when no directory is given.  This was causing tracebacks.
        * Fix for the LM63 model for the relax_disp.cpmgfit_input user function.  The grid search was incorrectly set up - the parameter is Tau, not tex.
        * Fixes for the IT99 model for the relax_disp.cpmgfit_input user function.
        * Changed the CPMGFit grid search options for the IT99 model in the relax_disp.cpmgfit_input user function.
        * Fix for the setup of the relaxation dispersion target functions for the IT99 model.
        * Added the relax optimisation results for the IT99 model applied to Flemming Hansen's CPMG data.
        * Removed an unnecessary calculation from the lib.dispersion.it99.r2eff_IT99() function.
        * Added the IT99 model to the software comparison table for Hansen's CPMG data.  This includes only the results from relax (and possibly not fully debugged results at that).
        * Replaced '-' with 'N/A' if the software is missing the model.  This is for the software comparison table using Flemming Hansen's CPMG data.
        * Updated the CPMGFit results for the IT99 model using Flemming Hansen's CPMG data.
        * Fixed the scaling of the parameter tex.
        * Fixes for the lib.dispersion.it99 module.  This is mainly because the omega_1eff parameter was not being correctly converted from the nu_cpmg values.
        * Updated the relax results for Flemming Hansen's CPMG data for the IT99 model fixes.
        * Fixes for the relax_disp.cpmgfit_input user function for the IT99 model grid search options.
        * Updated the CPMGFit results for the IT99 grid search fixes of the last commit.
        * Basic fix for the checks of the Relax_disp.test_hansen_cpmgfit_input user function.  The 'tex' parameter is now set as 'Tau'.
        * Disabled the Relax_disp.test_r1rho_on_res_fixed_time_m61b system test as the 'M61b' model is rubbish.The model cannot be properly optimised as the parameters are not independent of each other.
        * Fixes for the dispersion specific code.  The Grace graph code of lib.software.grace no longer accepts the axis min and max arguments.
        * Created the Relax_disp.test_bug_20889_multi_col_peak_list system test to catch bug #20889.  The report is https://gna.org/bugs/?20889.
        * Fixes for the Relax_disp.test_bug_20889_multi_col_peak_list GUI test.
        * Fixes for the checks of the Relax_disp.test_bug_20889_multi_col_peak_list GUI test.  Intensity errors will not have been calculated yet, and the structure is called baseplane_rmsd anyway.
        * Fix for the Relax_disp.test_bug_20889_multi_col_peak_list GUI test.  The peak intensity wizard _ok() method is now called to terminate the wizard.  Otherwise this causes the subsequent GUI test which tries to access the peak intensity wizard to fail.
        * Created the Relax_disp.test_hansen_cpmg_data_IT99 system test.  This is for testing the Ishima and Torchia 1999 2-site model for all timescales with pA >> pB.  This commit follows step 7 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Initialised the relaxation dispersion chapter in the relax manual.
        * Added 600x600 pixel version of the relaxation dispersion analysis graphic.  This is for use in the relax manual.
        * Fix for the definition of the \Ronerho LaTeX command for the relax manual.
        * Added EPS versions of the nessy and relax_disp 128x128 icons for the relax manual.
        * Added icons of all the sizes for ShereKhan.
        * Updated the relaxation dispersion 128x128 EPS icons to be the correct size and colour.
        * Updated the relaxation dispersion analysis EPS graphic to be the correct size and colour.
        * Copied the tutorial for adding dispersion modes to relax into the manual.  This was copied from http://article.gmane.org/gmane.science.nmr.relax.devel/3907.
        * Editing of the tutorial for adding dispersion models in the relax manual.
        * Edits of the relax_disp.select_model user function docstring.
        * Added all of the contents of the relax_disp.select_model user function docstring to the manual.
        * The relaxation dispersion parameters are now defined in the main manual LaTeX file.
        * Added a couple of sentences about bit rot to the dispersion chapter of the relax manual.  This is to the test suite part of the tutorial on adding new dispersion models.
        * The dispersion auto-analysis now saves the final program state before terminating.
        * Shifted the dispersion specific Grace plotting code into specific_analyses.relax_disp.disp_data.  The private _plot_disp_curves() and _plot_exp_curves() methods of the analysis specific object are now public functions of the specific_analyses.relax_disp.disp_data module.
        * Removed the state.save user function calls from the relax scripts for Hansen's CPMG data.
        * Updated the model lists for the relax scripts for Flemming Hansen's CPMG data.
        * Added a sample script for the relaxation dispersion analysis of CPMG-type data.
        * Added a preliminary icon set for spin clustering.
        * The relax_disp.cluster user function GUI menu entry now uses the cluster icon.
        * Created a very basic GUI element for the dispersion analysis for clustering.  This is simply to make this feature more obvious.  The button just launches the relax_disp.cluster user function.
        * Modified the experiment type descriptions in the dispersion GUI.
        * Shifted the spin cluster GUI element to be just after the spin system GUI element.  This is simply a more logical placement.
        * Modified the title of the dispersion auto-analysis GUI element, removing the 'Setup for' text.
        * Removed some unused imports from the CPMG dispersion analysis sample script.
        * Added the CPMG dispersion analysis sample script to the relax manual.
        * Epydoc docstring fixes for all of the modules of the lib.dispersion package.
        * Alphabetical ordering of imports.
        * Shifted the core of the relaxation dispersion API object into its own api module.  This is to simplify the relax import cascade - by removing the code from the specific_analyses/relax_disp/__init__.py file, the import of the package no longer results in the imports of other relax modules and packages.
        * Expanded the modelling of dispersion data section of the relax user manual.
        * Expansion of the modelling of dispersion data section of the relax user manual.
        * The relaxation dispersion auto-analysis now outputs text and Grace files for all parameters.  This is in response to bug #20917 (https://gna.org/bugs/?20917) submitted by Troels Linnet (https://gna.org/users/tlinnet).
        * The Monte Carlo simulations now generate parameter errors for the relaxation dispersion analysis.  The simulation index was being ignored, hence the input data was never the randomised data and all errors were zero.
        * Removed many decimal points from the MHz value in the Grace plots from relax_disp.plot_disp_curves.
        * Added support for converting between kex and tex, and pA and pB for the dispersion analysis.  This is performed by the new specific_analyses.relax_disp.parameters.param_conversion() function.  For this, most of the code from the assemble_param_vector() function has been shifted into get_value(), and most of disassemble_param_vector() into set_value().  The dispersion analysis now also has a custom sim_init_values() method to handle these parameters.
        * Added support for calculating auxiliary parameter errors for the dispersion analysis.  This is via the monte_carlo.error_analysis user function.  The errors for the parameter pairs kex-tex and pA-pB for the non-model parameter are now calculated as well.
        * Fix for the dispersion auto-analysis - pA and pB parameters are no longer output for the IT99 model.  These are not parameters of this model.
        * Updated the relax results for Flemming Hansen's truncated CPMG data for all the recent changes.
        * Fix for bug #20916, (https://gna.org/bugs/?20916) - Suggestion for Python script for PNG/EPS/SVG conversion of grace files.  Troels Linnet provided this patch, and was discovered during work on a Windows 7 system.  This patch will provide a grace2images.py file in each folder where a call to specific_analyses/relax_disp/disp_data.py is called.  It is called in plot_disp_curves(dir=None, force=None) and call the function lib.software.grace.script_grace2images().  The conversion script can be executed in Linux and Windows, if the PATH to xmgrace has been specified.  It will look in a folder for grace files of ending *.agr and by default convert to PNG.  One can also convert to EPS and SVG.  Probably more options could be added, as PDF.  The conversion depends on xmgrace compilation, and so PNG conversion is for fast inspection of graphs in folder, and EPS for further external conversion to PDF etc.  The patch, the output file, and small script to test is attached.  I miss to make the file executable in relax, so the script can be executed directly in Linux.
        * Mac OS X bug fix for the new analysis GUI wizard.  The blank button is now using the blank_150x150.png file instead of no image, preventing nasty wxPython bugs from appearing on that system.
        * Fix for bug #20917 (https://gna.org/bugs/?20917).  The problem is that the Grace files for each spin system are not created by the relax_disp.plot_disp_curves user function as the ':' character cannot be placed in a file name in MS Windows.  All of the file name from the ':' onwards is lost.  The solution is to replace each of the characters '#:@' in the spin ID string with '_'.
        * Another update of the relax results for Flemming Hansen's truncated CPMG data.  This includes the grace2images.py script creation contributed by Troels Linnet (https://gna.org/users/tlinnet) and the change of the file name of the per-spin dispersion curves.
        * The value checks in the Relax_disp.test_hansen_cpmg_data_auto_analysis system test are now less precise.  This is to allow the tests to pass on certain MS Windows systems.
        * Fix for the setting of the execute permissions on the grace2images.py scripts.  The problem was identified in the post at http://thread.gmane.org/gmane.science.nmr.relax.devel/3953/focus=4000.  This is within the relax_disp.plot_disp_curves user function after the grace2images.py script has been created.  The commit matches the changes from trunk for the Modelfree4 batch script.
        * Shifted from argparse to optparse in the grace2images.py scripts from relax_disp.plot_disp_curves.  This is associated with bug #20916 (https://gna.org/bugs/?20916) and the change suggested in the post http://thread.gmane.org/gmane.science.nmr.relax.devel/3953/focus=4000.  The argparse module is only available from for Python 2.7.3 (the version with many Python 3 features backported) and Python >= 3.2.  The module has been replaced with the similar optparse module as used by relax, and which available in all Python version supported by relax.
        * Updated the grace2images.py scripts created by the relax_disp.plot_disp_curves user function.  This was discussed in bug #20916 (https://gna.org/bugs/?20916) and the change suggested in the post http://thread.gmane.org/gmane.science.nmr.relax.devel/3953/focus=4000.  Improved that both small and big letters for image types can be used on the command line.
        * Converted the relaxation dispersion chapter of the user manual to the lstlisting environment.  This matches the changes occurring within the trunk.
        * Added an EPS version of the 128x128 cluster icon for the user manual.
        * Renamed the LaTeX file for the relaxation dispersion chapter of the user manual.
        * Completed the script UI section of the relaxation dispersion chapter of the user manual.  The sample script is now fully explained.
        * Added a demonstration of why the Ishima and Torchia 2005 error formula is incorrect.  The script test_suite/shared_data/dispersion/error_testing/simulation.py has been added to simulate the fixed relaxation time period error propagation.  This produces the test_suite/shared_data/dispersion/error_testing/error_plot.agr Grace graph.  The formula, graph and a description has been added to the relax manual explaining everything.
        * Fix of the two-point dispersion error formula in the docs.  This includes the relax_disp.select_model user function docstring and the relax manual.
        * Loosened a parameter check in the Relax_disp.test_hansen_cpmg_data_IT99 system test to pass on certain Linux systems.
        * Small edit of the legend of the relaxation dispersion figure showing the Ishima & Torchia 2005 being wrong.
        * Added Paul Schanda's code for the numerical solution to the Bloch-McConnell equations for 2-sites.  This is specifically code which uses complex conjugate matrices.  The code was submitted at http://thread.gmane.org/gmane.science.nmr.relax.devel/4132.
        * Made the lib.dispersion.ns_2site_star module importable in the absence of Scipy.
        * Polished the lib.dispersion.ns_2site_star module docstring.
        * Added some code missing from the lib.dispersion.ns_2site_star module.  This code was accidentally not copied from http://thread.gmane.org/gmane.science.nmr.relax.devel/4132.
        * Significant speed ups of the lib.dispersion.ns_2site_star.r2eff_ns_2site_star() function.  Replicated calculations have been minimised.
        * Added the 'NS 2-site star' model to the specific_analyses.relax_disp.variables module.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex conjugate matrices.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the lib.dispersion.ns_2site_star module name to the package __all__ list.
        * Updated the lib.dispersion.ns_2site_star module with additional information from Paul Schanda.  The details come from http://thread.gmane.org/gmane.science.nmr.relax.devel/4132/focus=4135.  The exchange-free R2 value parameter names have been changed to match the convention of the other lib.dispersion modules.
        * Added the 'NS 2-site star' model to the relax_disp.select_model user function frontend.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex conjugate matrices.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Fix for the non-ASCII character '\xe2' in the lib.dispersion.ns_2site_star module.
        * Created the 'NS 2-site star' model target function.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex conjugate matrices.  This commit follows step 4 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the R2B parameter as required by the 'NS 2-site star' model.

This commit follows step 5 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the 'NS 2-site star' model to the relax_disp.select_model user function back end.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex conjugate matrices.  This commit follows step 6 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Better support for the R2A and R2B relaxation rate parameters in the relaxation dispersion analysis.  This includes a number of fixes to allow these two parameters to be handled correctly.
        * Added parameter conversions to go from pA and kex to kge and keg.  This is for the 'NS 2-site star' numerical model.  The conversions have been added to the start of the target function to minimise mathematical operations to speed up the code.
        * Added the missing mpower() function as lib.linear_algebra.matrix_power.square_matrix_power().  This is needed by the lib.dispersion.ns_2site_star module.  The function comes from the 'fitting_main_kex.py' file attached to comment 3 of task #7712 (https://gna.org/task/?7712#comment3, https://gna.org/support/download.php?file_id=18263).  The mpower() function was copied and modified to suite relax's coding conventions.
        * Added a module docstring to lib.linear_algebra.matrix_power.
        * Created the lib.dispersion.ns_matrices module.  This module contains a collection of functions for generating the relaxation matrices for the numerical solutions to the Bloch-McConnell equations for relaxation dispersion.  The code comes from the 'fitting_main_kex.py' file attached to https://gna.org/task/?7712#comment3(https://gna.org/support/download.php?file_id=18263).
        * Docstring fix for the lib.dispersion.ns_matrices.rcpmg_2d() function.
        * Added the functions for creating the X-axis pi-pulse rotation matrices in lib.dispersion.ns_matrices.  The code comes from the 'fitting_main_kex.py' file attached to https://gna.org/task/?7712#comment3(https://gna.org/support/download.php?file_id=18263).
        * Huge amounts of documentation added to the lib.dispersion.ns_2site_star module.  This comes from Paul Schanda's (https://gna.org/users/pasa) post at http://thread.gmane.org/gmane.science.nmr.relax.devel/4132/focus=4152
        * Spacing fixes for the lib.dispersion.ns_2site_star module as determined by the 2to3 program.  This is the Python 2 to 3 conversion program.
        * Docstring fix for the lib.dispersion.ns_2site_star.r2eff_ns_2site_star() function.
        * Comment updates in the lib.dispersion.ns_2site_star module.
        * Completed the conversion of the ground and excited states (G, E) to the A and B states.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4132/focus=4154.
        * Fixes for the construction of the complex conjugate matrix in lib.dispersion.ns_2site_star.
        * The chemical shift difference is now passed into lib.dispersion.ns_2site_star.  This is currently set to the fA parameter, though it is not yet clear if this is correct.
        * Basic fix for the lib.linear_algebra.matrix_power.square_matrix_power() function.
        * The fixed relaxation time period is now sent into the 'NS 2-site star' dispersion model.
        * Fix for the state G+E to A+B conversion in lib.dispersion.ns_2site_star.
        * The 'NS 2-site star' model is now more robust against math domain failures.  This includes the failure of the logarithmic of zero matrices.
        * Speed ups of the 'NS 2-site star' dispersion model optimisation.  The relaxation and magnitisation data structures are now initialised with the target function initialisation, rather than being created at each target function call.  The Rex and M0 matrices are now updated at the base of the target function rather than in the lib.dispersion.ns_2site_star module to minimise the number of mathematical operations per target function call.  And the M0 matrix has changed shape and a dot product is used in lib.dispersion.ns_2site_star to create Moft instead.
        * Shifted to using the faster numpy.linalg.matrix_power() function in lib.dispersion.ns_2site_star.  This was originally using the lib.linear_algebra.matrix_power.square_matrix_power() function, however the numpy equivalent is faster.
        * More speed ups of the 'NS 2-site star' dispersion model.  A number of calculations have been shifted to the target function initialisation code, avoiding unnecessary repetitive mathematical operations.
        * Improvement of the error handling in the 'NS 2-site star' model.  The fA and pB parameters are no longer being checked.  Instead a Mgx value of 0.0 is being checked for.  This catches additional problems.  And now instead of the R2eff value being set to zero, it is set to 1e99.  This is because log of zero is -inf, and then multiplied by a negative constant gives positive inf.
        * Docstring completion for lib.dispersion.ns_2site_star.r2eff_ns_2site_star().  Epydoc text was missing for some of the function arguments.
        * Changed 'numerical integration' to 'numerical solutions' in the dispersion chapter of the manual.
        * Reworked the dispersion chapter of the manual for the recent support of numerical models.  This includes better sectioning and section labelling and referencing, and the addition of the 'NS 2-site star' numerical model.  The model and parameter tables have been updated as well.
        * Added the 'NS 2-site star red' model to the specific_analyses.relax_disp.variables module.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex conjugate matrices, whereby the simplification R20A = R20B is assumed.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Rewrote the relax_disp.select_model user function documentation.  All of the detailed model information has been removed as it is now in the relax user manual.  The model lists have been modified to match the analytic-numeric sectioning of the manual.
        * Added the 'NS 2-site star red' model to the relax_disp.select_model user function frontend.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex conjugate matrices, whereby the simplification R20A = R20B is assumed.

        * Docstring fix for the lib.dispersion.ns_2site_star.r2eff_ns_2site_star() function.
        * Created the 'NS 2-site star red' model target function.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations using complex conjugate matrices, whereby the simplification R20A = R20B is assumed.  The code in common with the 'NS 2-site star' model has been shifted into the new calc_ns_2site_star_chi2() method.  This commit follows step 4 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Fix for the Monte Carlo simulations for the numeric dispersion models.  The back-calculation method was not correctly initialising the target function class.
        * Added the 'CR72 red' model to the specific_analyses.relax_disp.variables module.  This is the Carver and Richards 1972 analytic model with the simplification R20A = R20B.  The current 'CR72' makes the same assumption, but that model will be expanded to support R20A and R20B later.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'CR72 red' model to the relax_disp.select_model user function frontend.  This is the Carver and Richards 1972 analytic model with the simplification R20A = R20B.

        * Added the 'CR72 red' model to the relax user manual.  This is the Carver and Richards 1972 analytic model with the simplification R20A = R20B.  The current 'CR72' makes the same assumption, but that model will be expanded to support R20A and R20B later.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * LaTeX improvements for the 'NS 2-site star red model' section of the dispersion chapter of the manual.
        * Expanded the CR72 model to handle both the R20A and R20B parameters.  The 'CR72 red' model now functions as the old CR72 model where R20A = R20B = R20.  All parts of the code have been modified.  The lib.dispersion.cr72.r2eff_CR72() function has been expanded to support the full Carver and Richards 1972 equations, dropping back to the simplified form if R20A = R20B.
        * Fix for the dispersion specific loop_parameters() method for the R20A and R20B parameters.  The frequency index is now correctly returned for these and the R20 parameter.
        * Better printouts of the R20A and R20B parameters at the end of minimisation.
        * Documentation fix for the lib.dispersion.cr72 module.
        * Small speed up for the lib.dispersion.cr72 module for the R20A != R20B case.  Replicated calculations have been minimised.
        * Added support for model nesting in the relaxation dispersion auto-analysis.  This involves copying the parameters from the simpler nested model rather than performing a full grid search.  This is currently used to handle all models with R20A and R20B parameters where a simpler model with the single R20 parameter is optimised first.
        * Improvements for the write_results() method of the dispersion auto-analysis.  The parameter value and Grace files are now correctly created for all the recent models.
        * Fix for the Relax_disp.test_hansen_cpmg_data_auto_analysis system test for model name change.  This is for the change from the 'CR72' model to 'CR72 red' model.
        * Added the 'NS 2-site' model to the specific_analyses.relax_disp.variables module.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations.

This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'NS 2-site' R2eff calculating function to the relax library.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations.  It originates as optimization function number 1 from the fitting_main_kex.py script from Mathilde Lescanne, Paul Schanda, and Dominique Marion (see http://thread.gmane.org/gmane.science.nmr.relax.devel/4138, https://gna.org/task/?7712#comment2 and https://gna.org/support/download.php?file_id=18262).  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Updates and fixes for the lib.dispersion.ns_2site module.  The function has been renamed, and the R1 arguments default to 0.0.  The flip angle for the from the pulse.
        * Created the 'NS 2-site' model target function.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations.  It originates as optimization function number 1 from the fitting_main_kex.py script from Mathilde Lescanne, Paul Schanda, and Dominique Marion (see http://thread.gmane.org/gmane.science.nmr.relax.devel/4138, https://gna.org/task/?7712#comment2 and https://gna.org/support/download.php?file_id=18262).  This commit follows step 4 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Converted the 'NS 2-site' model to 'NS 2-site 3D' to be more specific.  This might change again in the future.
        * Added support for the 'NS 2-site 3D' model to the relax_disp.select_model user function back end.  This is the model of the numerical solution for the 2-site Bloch-McConnell equations.  It originates as optimization function number 1 from the fitting_main_kex.py script from Mathilde Lescanne, Paul Schanda, and Dominique Marion (see http://thread.gmane.org/gmane.science.nmr.relax.devel/4138, https://gna.org/task/?7712#comment2 and https://gna.org/support/download.php?file_id=18262).  This commit follows step 6 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Lots of fixes for the relaxation dispersion target function module for the 'NS 2-site 3D' model.
        * Improvements to the nesting() method of the relaxation dispersion auto-analysis.  The use of the parameters of the simpler model in a nested pair now only works if the simpler model is in the model list.
        * Converted the pi-pulse propagator matrices to numpy array format.  This is to enable the use of the much faster numpy.dot() function for performing the dot products.
        * Speed ups for the 'NS 2-site 3D' model.  The pi-pulse propagator is created only once upon target function initialisation rather than for each function call, each spin cluster, each magnetic field strength, each dispersion point, and each CPMG block.
        * Modified the df, fA, and fB parameters to match the relax omega conventions of dw, wA, and wB.  This follows from Paul Schanda's confirmation at http://thread.gmane.org/gmane.science.nmr.relax.devel/4132/focus=4159.
        * Speed up for the lib.dispersion.ns_matrices.rcpmg_3d() function.  The pA and pB parameters are now sent into the function rather than being recreated by the function.
        * More changes to the numerical solution dispersion code to match relax's conventions.  This includes the changes of df->dw, fA->wA, fB->wB, and Mgx->Mx.
        * Added the 'NS 2-site 3D red' model to the specific_analyses.relax_disp.variables module.  This is the 'NS 2-site 3D' model with R20A = R20B = R20.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).

        * Updated all of the numerical model sections of the dispersion chapter of the manual.  This includes additions for the 'NS 2-site 3D' and 'NS 2-site 3D red' models.
        * Updated the 'NS 2-site 3D' and 'NS 2-site 3D red' models in the dispersion chapter of the relax manual.  The models are now included in the tables and in the introduction.
        * Added support for nesting to the relaxation dispersion auto-analysis for the 'NS 2-site 3D*' models.
        * Added the 'NS 2-site expanded' model to the specific_analyses.relax_disp.variables module.  This is the numerical model for the 2-site Bloch-McConnell equations expanded using Maple by Nikolai Skrynnikov.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'NS 2-site expanded' model to the relax_disp.select_model user function frontend.

This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'NS 2-site expanded' R2eff calculating function to the relax library.  This is the numerical model for the 2-site Bloch-McConnell equations expanded using Maple by Nikolai Skrynnikov.  It originates as optimization function number 5 from the fitting_main_kex.py script from Mathilde Lescanne, Paul Schanda, and Dominique Marion (see http://thread.gmane.org/gmane.science.nmr.relax.devel/4138, https://gna.org/task/?7712#comment2 and https://gna.org/support/download.php?file_id=18262).  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Fix for the lib.dispersion.ns_2site_expanded.r2eff_ns_2site_expanded() function.  The pg variable should have been pA and it needs to be sent into the function.
        * Created the 'NS 2-site expanded' model target function.  This is the numerical model for the 2-site Bloch-McConnell equations expanded using Maple by Nikolai Skrynnikov.  It originates as optimization function number 5 from the fitting_main_kex.py script from Mathilde Lescanne, Paul Schanda, and Dominique Marion (see http://thread.gmane.org/gmane.science.nmr.relax.devel/4138, https://gna.org/task/?7712#comment2 and https://gna.org/support/download.php?file_id=18262).

This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Large renaming of the relaxation dispersion models.  This includes both the analytic and numerical models.  All of the models with separate R20A and R20B parameters now have ' full' added to the end of the model name.  And all of the corresponding reduced models whereby R20A = R20B = R20 have had the trailing ' red' removed.  All descriptions and variable names have been updated to match.
        * Updated the dispersion auto-analysis write_results() method for the recent model changes.
        * Import fix for the 'NS 2-site expanded' dispersion model target function.
        * Fix for the lib.dispersion.ns_2site_expanded module for the missing sqrt() function import.
        * Simplified the test_hansen_cpmg_data_*() system tests by shifting most shared code into setup_hansen_cpmg_data().
        * Created the Relax_disp.test_hansen_cpmg_data_CR72_full system test for checking the 'CR72 full' model.
        * Expanded the dispersion target function class docstring to include all current dispersion models.
        * Updated the parameter checks in the Relax_disp.test_hansen_cpmg_data_CR72_full system test.
        * Fixes for all of the definitions of the k_AB and k_BA exchange parameters.  These were inverted in all parts of relax.  The changes only affect the numerical dispersion models.
        * Created the Relax_disp.test_hansen_cpmg_data_ns_2site_3D system test.  This checks the 'NS 2-site 3D' numerical dispersion model against some truncated CPMG data from Flemming Hansen.
        * Created the Relax_disp.test_hansen_cpmg_data_ns_2site_3D_full system test.  This checks the 'NS 2-site 3D full' numerical dispersion model against some truncated CPMG data from Flemming Hansen.  The parameter checks have not been updated as there appears to be a bug.
        * Created system tests for the rest of the numerical dispersion models.  These include Relax_disp.test_hansen_cpmg_data_ns_2site_expanded, Relax_disp.test_hansen_cpmg_data_ns_2site_star and Relax_disp.test_hansen_cpmg_data_ns_2site_star_full.  This checks the 'NS 2-site expanded', 'NS 2-site star', and 'NS 2-site star full' numerical dispersion models against some truncated CPMG data from Flemming Hansen.  The parameter checks have not been updated for the 'NS 2-site expanded' and 'NS 2-site star full' models as there appears to be bugs.
        * Fixes for the Relax_disp.test_hansen_cpmg_data_auto_analysis system test.  The checks for the 'CR72 red' model are now against the 'CR72' model.  And the models optimised only now include 'No Rex', 'LM63', 'CR72', and 'IT99', massively speeding up the test.
        * Fixes for the lib.dispersion.ns_2site_expanded module.  These problems were identified using the Relax_disp.test_hansen_cpmg_data_ns_2site_expanded system test.  They correspond to the issues with the original fitting_main_kex.py program identified by Mathilde Lescanne in her post at http://thread.gmane.org/gmane.science.nmr.relax.devel/4144.
        * The Relax_disp.test_hansen_cpmg_data_ns_2site_expanded system test now passes.  The test has been set up to match Relax_disp.test_hansen_cpmg_data_CR72.  This allows the efficiency of each method to be compared by running the tests with the --time flag.
        * Fix for the model nesting method of the relaxation dispersion auto-analysis for deselected spins.
        * Added an upper constraint of 2e6 rad/s for the kex dispersion parameter.  This is to prevent slow optimisation to values in the order of 1e20 for models which fail.
        * Updated the model lists for the relax scripts for optimising Flemming Hansen's CPMG data.  The model lists now include the numeric models and the 'CR72 full' model.
        * The lib.software.grace.write_xy_header() can now set the legend fill pattern and font size.
        * The relax_disp.plot_disp_curves user function backend now sets clear legend boxes with smaller text.
        * Fix for the Grace string for the dw dispersion parameter.
        * Updated the parameter value checks in the Relax_disp.test_hansen_cpmg_data_CR72 system test.  The low precision parameters are slightly different because of the new upper constraint on kex, simply because optimisation is terminated early rather than optimisation giving different results.
        * Updated the rest of the dispersion system tests to check the correct parameter values.  It is currently assumed that the 'full' dispersion models are correct as there is currently no way of testing if they are not.  So the Relax_disp.test_hansen_cpmg_data_ns_2site_3D_full and Relax_disp.test_hansen_cpmg_data_ns_2site_star_full system tests have been updated to pass.
        * Modified how the relaxation dispersion auto-analysis handles Monte Carlo simulations.  Now there is a flag which allows per-model simulations to be enabled.  By default, simulations are now only performed at the end.  This is to allow for massive speed ups in the auto-analysis.
        * Modified the dispersion GUI analysis to not include all dispersion models.
        * Added Mathilde Lescanne to the copyright notices of the numeric dispersion code in the relax library.  The dates must still be checked and updated correctly.
        * Added support for the mc_sim_all_models flag for the dispersion auto-analysis in the GUI.  The new boolean auto-analysis GUI input element is being used for this purpose.
        * All of the numeric dispersion models are now much more robust.  The real part of the magnetization vector for the A state could, for some parameter combinations, be either negative or NaN.  These situations are now caught, and the R2eff value set to a very large number.
        * Sectioning improvements for the relaxation dispersion chapter of the relax user manual.
        * Added DOI numbers to a number of bibliography entries for quick links in the relax user manual.
        * Added the 'LM63 3-site' model to the specific_analyses.relax_disp.variables module.  This is the Luz and Meiboom 1963 analytic model for three exchanging sites.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'LM63 3-site' model to the relax_disp.select_model user function frontend.  This is the Luz and Meiboom 1963 analytic model for three exchanging sites.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'LM63 3-site' model to relaxation dispersion chapter of the relax user manual.  This is the Luz and Meiboom 1963 analytic model for three exchanging sites.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'LM63 3-site' R2eff calculating function to the relax library.  This is the Luz and Meiboom 1963 analytic model for three exchanging sites.  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Fixes for the 'LM63 3-site' model equations in the relaxation dispersion chapter of the user manual.
        * Created the 'LM63 3-site' model target function.  This is the Luz and Meiboom 1963 analytic model for three exchanging sites.  This commit follows step 4 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support to the relaxation dispersion analysis for the 'LM63 3-site' model parameters.  This is the Luz and Meiboom 1963 analytic model for three exchanging sites.  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the 'LM63 3-site' model to the relax_disp.select_model user function back end.  This is the Luz and Meiboom 1963 analytic model for three exchanging sites.  This commit follows step 6 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the 'LM63 3-site' parameters to the specific_analyses.relax_disp.parameters module.  This is the Luz and Meiboom 1963 analytic model for three exchanging sites.  This commit follows step 5 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'LM63 3-site' model to the dispersion scripts for Flemming Hansen's CPMG data.
        * The relaxation dispersion auto-analysis can now resume if it has been interrupted.
        * Some fixes for the 'LM63 3-site' dispersion model.  The library code was not accepting the correct arguments and it was referencing a non-existent parameter, and the grid search setup was failing.
        * Added support for optimising the 'LM63 3-site' dispersion model with Art Palmer's CPMGFit.  This is for the relax_disp.cpmgfit_input user function.  This model in CPMGFit is called '3-site_CPMG'.
        * Python 3 fixes for the specific_analyses.relax_disp.disp_data module.
        * Fixes for the relax_disp.cpmgfit_execute user function backend.  This would hang if CPMGFit produced error messages.  Hopefully this is now fixed.
        * Updated the CPMGFit results for the 'LM63 3-site' model.  This is for the truncated CPMG data from Flemming Hansen.
        * Speed ups for the 'LM63 3-site' target function.  Some mathematical operations have been shifted from the library code into the target function so that is only calculates once per function call.
        * Updated the relax results for Flemming Hansen's truncated CPMG data for the 'LM63 3-site' model.
        * The dispersion auto-analysis now outputs files for the kB, kC, phi_ex_B, and phi_ex_C parameters.  This is in the write_results() method and is for creating text files and Grace plots for the 'LM 3-site' model.
        * Created some synthetic test data for the 'LM63 3-site' dispersion model.  This will be used to test CPMGFit and relax's implementations.
        * Updated the 'LM63 3-site' dispersion model test data.  The CPMG frequencies are now more realistic.
        * Removed the old Sparky peak lists for the 'LM63 3-site' dispersion model test data.
        * Added the new Sparky peak lists for the 'LM63 3-site' dispersion model test data.
        * Updated the reference Sparky peak lists for the 'LM63 3-site' dispersion model test data.
        * Missing import of the specific_analyses.relax_disp.variables.MODEL_LM63_3SITE variable.
        * Added scripts for calculating the R2eff values for the 'LM63 3-site' dispersion model test data.
        * Created the Relax_disp.test_r2eff_fit_fixed_time system test to show a failure in the auto-analysis.  This shows a failure of the R2eff fitting in the dispersion auto-analysis due to Monte Carlo simulations being run when the calc() function should be called.
        * Removed some parts of the Relax_disp.test_r2eff_fit_fixed_time system test.  The last lines were non-functional.
        * Fix for the dispersion auto-analysis if not enough models have been input for a final run.  The final model selection, Monte Carlo simulation, and results writing stage of the auto-analysis now only occurs when enough models are present for model selection.
        * Fix for the dispersion auto-analysis for when only the single R2eff model is optimised.  This is for the case of exponential curve fitting, and allows Monte Carlo simulations to proceed even when the mc_sim_all_models flag is False.
        * Removed some unused parts of the r2eff_calc.py script and added the results file.
        * Made the 'LM63 3-site' dispersion model test data more realistic.  Previously all the rates were within a few decimal places of the R20 values.  Now the dispersion is much more significant.
        * Modified the 'LM63 3-site' dispersion model test data again.  This time the data has been changed to be that of two residues rather than two spins.
        * Another update of the 'LM63 3-site' dispersion model test data.  This data now makes CPMGFit happy.
        * Added the CPMGFit results for the 'LM63 3-site' dispersion model test data.
        * Added the relax results for the 'LM63 3-site' dispersion model test data.
        * Added a warning not to use the 'LM63 3-site' model to the dispersion chapter of the user manual.
        * Added the 'LM63 3-site' dispersion model to the model list in the GUI.  It is not selected by default.
        * Updated the Noe.test_noe_analysis system test.  These were the changes to the lib.software.grace.write_xy_header() function.
        * Fix for the model equivalence setup in the nesting() method of the dispersion auto-analysis.  This is the use of the analytic CR72 model parameters for the numeric models to avoid the grid search.
        * Removed a double full stop in the relax_disp.select_model docstring.
        * Updates for the test suite data script for optimising Flemming Hansen's CPMG data.  The model list has been shorted to the useful models, and the grid search size is now reasonable.
        * Updated the software_comparison file for the numeric model results from relax.  This is the file comparing the results for residues 70 and 71 from Flemming Hansen's CPMG data.
        * Updated the numeric model results for the software_comparison file.
        * Updated the relax results for Flemming Hansen's truncated CPMG data.  This includes the 'CR72 full' model and all the numeric models (excluding the *full models).
        * Added Dominique Marion to the copyright notices of all the lib/dispersion/ns_*.py files.  This is in response to Paul Schanda's message at http://thread.gmane.org/gmane.science.nmr.relax.devel/4225/focus=4226.
        * Small fix for the relax_disp.cluster documentation.
        * Added the new pre_run_dir argument to the relaxation dispersion auto-analysis.  This is to enable clustered optimisation.  This specifies a directory containing a completed analysis.  The parameters from this previous run will be used as the starting point for optimisation of the clustered analysis.
        * Fix for the Monte Carlo simulations for the dispersion auto-analysis failing under certain conditions.  The wrong variable was being checked to see if more than two models were being optimised.
        * The dispersion minimisation() method now skipped deselected spin clusters.  This is defined as all spins of the cluster being deselected.
        * Implemented the new relax_disp.parameter_copy user function.  This is used to copy relaxation dispersion parameters from one data pipe to another, taking cluster averaging into account.  It is used by the dispersion auto-analysis to handle clustering.
        * Added an element to the dispersion GUI analysis for specifying the directory of previous results.  This is used for the pre_run_dir argument for the dispersion auto-analysis.
        * Reactivated Monte Carlo simulations for the 'R2eff' model for exponential data curves.  This is within the optimise() method of the dispersion auto-analysis.
        * Updated the intro chapter of the user manual for the now supported dispersion analysis.  This is no longer listed as a future to be implemented feature.
        * Updated the screenshot of the analysis selection wizard to include the dispersion analysis.  This new figure has been updated in the intro chapter of the relax user manual as well.
        * Renamed an instance of 'numerical simulation' in the dispersion chapter of the manual.
        * Fix for the final data pipe in the dispersion auto-analysis.  The final data pipe is now placed in the data pipe bundle.  This is needed to allow the final state file to be opened in the GUI with an associated GUI analysis tab.
        * Fixes for the clustering display in the GUI.  This is for the relaxation dispersion GUI analysis tab.
        * Updated the README file for Dr. Flemming Hansen's CPMG data in the test suite.
        * Added Martin Tollinger to the copyright of the lib.dispersion.ns_2site_expanded module.  This follows Martin's post at http://article.gmane.org/gmane.science.nmr.relax.devel/4276.
        * Added links to all of the copyright licensing agreements for the lib.dispersion.ns_2site_expanded module.
        * Added Nikolai Skrynnikov to the copyright notice of the lib.dispersion.ns_2site_expanded module.
        * Added the 'TP02' model to the specific_analyses.relax_disp.variables module.  This is the Trott and Palmer 2002 R1rho analytic model for 2-site exchange.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'TP02' model to the relax_disp.select_model user function frontend.  This is the Trott and Palmer 2002 R1rho analytic model for 2-site exchange.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'TP02' model to relaxation dispersion chapter of the relax user manual.  This is the Trott and Palmer 2002 R1rho analytic model for 2-site exchange.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'TP02' R1rho' calculating function to the relax library.  This is the Trott and Palmer 2002 R1rho analytic model for 2-site exchange.  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).  The Matlab code from Skrynnikov and Tollinger has not been converted to Python code yet.  This is to allow the Matlab->Python conversion to be followed.
        * Fix for the 'M61 skew' dispersion model indexing in the user manual.
        * Added the 'NS 2-site expanded' model to the CPMG dispersion sample script.
        * Added the 'NS 2-site expanded' and 'TP02' models to the script in the manual.  This is in the script section of the dispersion chapter of the user manual.
        * Converted the lib.dispersion.tp02 module from Matlab code to Python.  The code has also been made fail-safe and repetitive calculations have been shifted outside of the loop to speed things up.
        * Fixes for the TP02 model section of the dispersion chapter of the manual.
        * Created the 'TP02' model target function.  This is the Trott and Palmer 2002 R1rho analytic model for 2-site exchange.  This commit follows step 4 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the 'TP02' model to the relax_disp.select_model user function back end.  This is the Trott and Palmer 2002 R1rho analytic model for 2-site exchange.  This commit follows step 6 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * The spectrometer frequency information is now checked for the TP02 model.
        * Started to create a script to create synthetic data for the TP02 dispersion model.  This still needs a lot of work.
        * Added the tp02 module to the lib.dispersion package __all__ list.
        * Created the synthetic data for the TP02 dispersion model.  The Sparky peak lists have been created and added to the repository.
        * Modified the synthetic data for the TP02 dispersion model.  The data is more closely mimics that from the paper, and should now be in the slow exchange regime.
        * Updated the M61 R1rho model conditions in the table in the user manual.
        * Updated the TP02 R1rho model conditions in the table in the manual.  This cannot be fast exchange.
        * Started to create the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.
        * A fix for older numpy versions, as the numpy.add() function argument 'out' is relatively new.
        * Added the new 'TSMFK01' model to the specific_analyses\relax_disp\variables.py module.  This is the Tollinger/Kay model for the 2-site very-slow exchange model for CPMG-type experiments, which cover the range of microsecond to second time scale.  Paper by M. Tollinger, N.R. Skrynnikov, F.A.A. Mulder, J.D.F. Kay and L.E. Kay (2001).  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * lib/dispersion/lm63.py is copied to tsmfk01.py as part of the implementation of the TSMFK01 model equation.

Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Created the TSMFK01 model target function for 2-site very-slow exchange model, range of microsecond to second time scale.

Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * The chemical shift of each spin is now taken into account for the synthetic data for the TP02 dispersion model.  The data now properly reflects the spin lock offset.
        * Updated all of the dispersion system tests for the spectrum.read_intensities user function changes.  The arguments heteronuc and proton have been replaced with 'dim'.
        * Improved the error message for when peak intensity data cannot be found in a dispersion analysis.  This is to better aid the user to track down what they did wrong.
        * More error message improvements for when peak intensity data cannot be found in a dispersion analysis.
        * Created the relax script for the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.
        * Changed the synthetic data file names for the TP02 dispersion model.
        * Updated the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test script for the new file names.
        * Added a new user function to the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.  This is the chemical_shift.read user function which currently does not exist.  Chemical shifts are needed to interpret off-resonance R1rho data.
        * Copyright of Sebastien Morin and Edward d'Auvergne re-inserted, since tsmfk01 is an alteration of lm63.py and m61.py in same directory.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix for converting dw from ppm to rad/s.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added support for the TSMFK01 model to the relax_disp.select_model user function back end.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix for the reading of chemical shifts in the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.
        * Added the Trott and Palmer, 2002 bibtex reference for the user manual.
        * Added preliminary support for chemical shifts to the dispersion target functions.
        * Modified the GUI behaviour for a dispersion analysis when the C modules are not compiled.  Previously a user was blocked from performing any dispersion analysis in the GUI is the modules were not compiled.  Now instead, although an error is still thrown, the analysis will be initialised.
        * A new check blocking exponential curve fitting in the dispersion analysis when the C modules are not compiled.
        * Changed how chemical shifts are handled in the dispersion target function class.  The chemical shifts in ppm are accepted and they are converted to rad/s inside the __init__() method.  A structure for rotating frame tilt angles is now also accepted.
        * Added a relax_disp.spin_lock_offset user function call to Relax_disp.test_r1rho_off_res_tp02.  This is the Relax_disp.test_r1rho_off_res_tp02 system test and the user function does not exist yet.
        * Implemented the relax_disp.spin_lock_offset user function.  This includes both the front end and the back end specific_analyses.relax_disp.disp_data.spin_lock_offset() function.
        * The offset is now set for all spectra in the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.  Previously only the reference was set.
        * Fixed a typo in the dispersion chapter of the user manual.  This was identified by Troels Linnet at http://thread.gmane.org/gmane.science.nmr.relax.devel/4410.
        * Fix for the relax_disp.spin_lock_offset user function.  The cdp.dispersion_points structure was being updated when it should not be touched - a remnant of the relax_disp.spin_lock_field backend which this code was copied from.
        * Added some more arguments to the dispersion target function class for off-resonance R1rho models.  This is the structure for the spin-lock offsets and the tilt angles for each spin.
        * Fix for the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.  The correct spectrum ID is now used for the relax_disp.spin_lock_offset user function calls in the script.
        * The dispersion specific optimisation code is now assembling chemical shift related data.  The specific_analyses.relax_disp.disp_data.return_offset_data() function has been written to return structures for the chemical shifts, offsets, and tilt angles.  These are then used by the optimisation functions by passing them into the target function code.
        * The TP02 model code is now in a semi functional state.  The lib.dispersion code has been fixed to properly handle the data it receives and the target function code has been updated to pass in the correct data.
        * The TP02 model R1rho off-resonance test data creation script now creates files of the R1 relaxation data.  These files are needed for the system tests, as R1 data needs to be read.
        * The dispersion target function class now handles R1 relaxation data.  This data is essential for the off-resonance R1rho models.
        * The Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test script now reads the R1 relaxation data.  This data is essential for the model optimisation.
        * The dispersion specific code is now assembling the R1 data and passing it to the target function.  The new specific_analyses.relax_disp.disp_data.return_r1_data() function creates a data structure holding all the R1 data.  This is used in the off-resonance R1rho experiments.
        * Added checks to the specific_analyses.relax_disp.disp_data.return_r1_data() function.  This is to help indicate to the user when data is missing.
        * Fix for the Relax_disp.test_bug_20889_multi_col_peak_list GUI test.  The spectrum.read_intensities user function no longer has 'heteronuc' and 'proton' arguments.
        * Fix to allow R1 data to be randomised for Monte Carlo simulations for off-resonance R1rho data.  This is a temporary kludge for the dispersion analysis and needs to be replaced by a cleaner solution via the base_data_loop() method.
        * Fix for the synthetic data for the TP02 dispersion model.  The nitrogen chemical shift was not converted from ppm to rad/s before being used to calculate the offsets.
        * Fixes for the parameter checks in the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.  The parameter values had not been updated from when the test was copied from one of the other tests.
        * Turned off clustering in the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.  This speeds the test up by more than half.
        * Fix for the TP02 dispersion model.  The rotating frame tilt angle for this model is calculated from the population averaged chemical shift and not the equal weighted average.
        * Attempt at fixing bug #21080 (https://gna.org/bugs/?21080).  This was reported by Troels Linnet.  The problem is a standard GUI problem.  The text from a wxPython GUI is a Unicode string.  But relax requires standard strings.  Therefore the gui.string_conv.gui_to_str() function needs to be used on the return value of the GUI element GetValue() method, but this call was forgotten.
        * Fix for the synthetic data for the TP02 dispersion model.  The chemical shift is being set to that of state A, the major species, rather than the non-weighted chemical shift average.  This could also have been set to the population weighted average.
        * The TP02 dispersion model now assumes the chemical shift is that of the major population A.  Previously the linear chemical shift average was assumed.
        * Increased the grid search size in the Relax_disp.test_r1rho_off_res_fixed_time_tp02 system test.
        * The self.field_pre_run_dir GUI element is now deactivated with the execution lock.
        * Many fixes and improvements for all of the R1rho dispersion models in the user manual.  The equations are now correct and the parameter table updated with new parameters and equations.
        * Removed the unused theta and R1 arguments for the lib.dispersion.m61.r1rho_M61() function.  These off-resonance parameters are not used in the on-resonance model.
        * Updated the r1rho_on_res_m61 dispersion on-resonance data for off-resonance models.  The chemical shifts are now the same for all spins, to force perfect on-resonance, and the two spins are now different residues.
        * Added an R1 data file to r1rho_on_res_m61, by copying from the r1rho_off_res_tp02 test suite data.
        * Updated the Relax_disp.test_r1rho_on_res_fixed_time_dpl94 system test for off-resonance data.  The offsets, R1 data, and chemical shifts are now setup or read by the script.
        * Fixes for the DPL94 model to make it truly off-resonance.  The tilt angles and R1 data are now used by the target function.
        * Fixes for the r1rho_on_res_m61.py system test script.  The spins are now different residues.  This fixes two system tests.
        * Renamed all of the current numeric dispersion models in relax to be specific to CPMG-type data.  This is in preparation for adding R1rho numeric models.  It was proposed at http://thread.gmane.org/gmane.science.nmr.relax.devel/4461.
        * Added the 'NS R1rho 2-site' model to the specific_analyses.relax_disp.variables module.  This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.  This commit follows step 1 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'NS R1rho 2-site' model to the relax_disp.select_model user function frontend.  This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'NS R1rho 2-site' R1rho calculating function to the relax library.  This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.  This code originates from the Skrynikov & Tollinger code (the sim_all.tar file https://gna.org/support/download.php?file_id=18404 attached to https://gna.org/task/?7712#comment5).  Specifically the funNumrho.m file.  This commit follows step 3 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Fix for the function name in the lib.dispersion.ns_r1rho_2site module and removed misplaced copyrights.
        * Created the 'NS R1rho 2-site' model target function.  This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.  The code originates from the funNumrho.m file from the Skrynikov & Tollinger code (the sim_all.tar file https://gna.org/support/download.php?file_id=18404 attached to https://gna.org/task/?7712#comment5).  This commit follows step 4 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added support for the 'NS R1rho 2-site' model to the relax_disp.select_model user function back end.  This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.  The code originates from the funNumrho.m file from the Skrynikov & Tollinger code (the sim_all.tar file https://gna.org/support/download.php?file_id=18404 attached to https://gna.org/task/?7712#comment5).  This commit follows step 6 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Added the 'NS R1rho 2-site' model to the relax user manual.  This is the numerical model for the 2-site Bloch-McConnell equations for R1rho data.  The code originates from the funNumrho.m file from the Skrynikov & Tollinger code (the sim_all.tar file https://gna.org/support/download.php?file_id=18404 attached to https://gna.org/task/?7712#comment5).  This commit follows step 2 of the relaxation dispersion model addition tutorial (http://thread.gmane.org/gmane.science.nmr.relax.devel/3907).
        * Rearrangement of the model sections in the dispersion chapter of the user manual.  These are now better separated into different categories.
        * Created a save file for the r1rho_off_res_tp02 dispersion data optimised to the R2eff model.  This will be used for faster system tests.
        * Created the Relax_disp.test_r1rho_ns_r1rho_2site_to_tp02 system test for the new 'NS R1rho 2-site' model.  This tests the 'NS R1rho 2-site' model against the R1rho off-resonance test data from the 'TP02' model.
        * A number of fixes for the 'NS R1rho 2-site' dispersion model.  The model should now be fully functional.  The chemical shift and R1 related data are now assembled for this model, and the data correctly passed from the target function to the lib.dispersion module.
        * The Relax_disp.test_r1rho_ns_r1rho_2site_to_tp02 system test now passes.  The optimised values have been hard-coded into the system test.  They do not match the TP02 results, but are close.
        * Renamed many of the Relax_disp system tests to bring some order to the naming.
        * Alphabetical ordering of all of the Relax_disp system tests.
        * Created a system test to catch bug #21081 (https://gna.org/bugs/?21081).  This uses a truncated version of Troel Linnet's save state attached to the bug report (the data pipes not used in the model selection have been manually deleted as well as all by the first 3 spins in the remaining 2 data pipes).
        * Fix for bug #21081 (https://gna.org/bugs/?21081) - the failure of a dispersion cluster analysis.  The problem was that the specific_analyses.relax_disp.disp_data.loop_cluster() generator method was not taking the spin.select flag into account.  Now all deselected spins are excluded from the spin clusters and the free spins.
        * Better support for off-resonance R1rho data in the dispersion GUI.  A new row of buttons has been added to the dispersion GUI, just above the Peak list GUI element.  The first button is for the spin.isotope user function and replaces the old GUI element.  Two new buttons for loading R1 data and chemical shifts have also been added, as required for off-resonance R1rho data.
        * Changed the chemical shift icon to that of the chemical shift in ppm units - the delta symbol.
        * The chemical shift icon now has a transparent background.
        * Small changes to the tooltips of the R1 and chemical shift buttons.
        * Used far more Unicode for superscript, subscript and Greek letters for the model parameters.  This is for the model list elements in the dispersion GUI tab.
        * Added the 'TP02' and 'NS R1rho 2-site' models to the R1rho model list in the dispersion GUI.  These models were missing from the list.
        * Fix for the 'NS R1rho 2-site' model description in the relax_disp.select_model user function.
        * The relax_disp.select_model GUI wizard combo element now uses Unicode for the dispersion parameters.  This is for all the models.  The 'LM63 3-site' model parameter list has also been fixed to match the current set.
        * The CPMGFit input and output file names for relaxation dispersion are now MS Windows compatible.  This is needed to allow the files in the test suite to exist on Windows systems, as the '#:@'symbols cause problems.  The same logic as used for the relax_disp.plot_disp_curves is used to replace these characters with an underscore.
        * CPMGFit file name fixes for MS Windows.  The '#:@' characters have all been replaced by underscores.
        * Fix for the Relax_disp.test_hansen_cpmgfit_input system test.  The '#:@' characters are no longer used in the file names.
        * Updates to the Relax_disp system tests for the lower precision of MS Windows.  These fixes allow the tests to pass on MS Windows.
        * Renamed ka parameter to kA, to be consistent with naming conventions.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix for r20 should be called r20a.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix for unpacking the parameters correctly.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added the k_AB and k_BA parameters to the table of all dispersion parameters.
        * Proper ordering of all the dispersion models.  See the thread at http://thread.gmane.org/gmane.science.nmr.relax.devel/4498 for details.
        * Added the 'NS R1rho 2-site' model to the dispersion auto-analysis.
        * Added the 'TP02' model to the dispersion auto-analysis.
        * The tutorial for adding dispersion models in the user manual has been simplified.  Most of the text from the dispersion model addition tutorial in the dispersion chapter of the manual has been removed.  Instead a link to the tutorial on the wiki is given as this is a much better place for such information (http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax).
        * Moved the ordering of the model TSMF.  Ordering conventions mentioned in this post http://article.gmane.org/gmane.science.nmr.relax.devel/4500.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added the relax_disp.spin_lock_offset user function to the peak intensity wizard of the GUI.  This is only for R1rho-type data and allows off-resonance data to be analysed in the GUI.
        * Data provided for the implementation of the slow-exchange analytic model of the Tollinger/Kay (2001).  This model were used for fitting in the paper http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1458987.
        * Created the Relax_disp.test_tp02_data_to_tp02 GUI test.  This is based on the system test of the same name.  This GUI test checks that an off-resonance R1rho analysis is functional in the GUI.
        * Python 3 space fixes for the lib.software.grace.script_grace2images() function.  As the script is encoded by strings, the 2to3 program cannot fix this script.  Therefore the changes were made by hand.
        * Unicode strings in the dispersion GUI elements is now set up with the compat.u() function.
        * Fix for the y-axis in the per spin dispersion curve plots.  This fix follows from the thread http://thread.gmane.org/gmane.science.nmr.relax.devel/4512.  The test for CPMG-type data was incorrect and should use the CPMG_EXP variable.
        * Added setup function for the system test of KTeilum_FMPoulsen_MAkke_2006 data.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fixed a spelling mistake in a number of file names.  This is for the test suite data located at test_suite/shared_data/dispersion/KTeilum_FMPoulsen_MAkke_2006.
        * Fixes for the units in the dispersion parameter table in the user manual.  The units for dw are rad.s^-1 when used in the equations, but it is stored internally as ppm.
        * Truncated the dataset to only one residue L61.  The truncated dataset will be expanded later.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Modified the script file for saving of a truncated base_pipe state file.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added script files for generating a saved state file with R2eff values.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added the first system test for model CR72 for the kteilum_fmpoulsen_makke_cpmg_data.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix trailing spaces.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix epydoc HTML markup code.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added some MQ dispersion data taken from the GUARDD program.
        * Modified the Relax_disp.test_dpl94_data_to_dpl94 system test for a relax_disp.exp_type change.  This is so that the relax_disp.exp_type user function associates the experiment types with a spectrum ID.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530.
        * Clean up and expansion of the dispersion experiment type variables.
        * Another change to the dispersion experiment type variables.
        * Fixes for the changes to the dispersion experiment type variables throughout the dispersion code.
        * Redesigned the relax_disp.exp_type user function to be associated with spectrum IDs.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.  The user function backend has been moved from specific_analyses.relax_disp.api to specific_analyses.relax_disp.disp_data.  A few temporary code additions have been made to keep the user function functional with the current dispersion code.
        * Fixes for the relaxation dispersion system tests for the relax_disp.exp_type changes.
        * The relaxation dispersion system tests requiring the compiled C modules are now skipped when not compiled.
        * Created the specific_analyses.relax_disp.disp_data.loop_exp*() functions.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.  The methods added are loop_exp(), loop_exp_frq(), loop_exp_frq_point() and loop_exp_frq_point_time().
        * Removed the relax_disp.exp_type user function page from the new analysis wizard.
        * Modified the dispersion GUI analysis to handle the relax_disp.exp_type user function changes.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.  The experiment type GUI element has been removed, the CPMG and R1rho model lists merged into one, and much code for the experiment type removed.  The peak analysis wizard will need to be heavily modified for the changes.
        * Added the relax_disp.exp_type user function to the peak intensity loading wizard.
        * Added the experiment type to the spectrum list GUI element.  This is only activated if the exp_type_flag argument is True.
        * The CPMG frequency and spin-lock field strength columns are merged in the spectrum list GUI element.  The column is now for the dispersion point data, and allows different experiment types to be mixed.
        * The spectra list GUI element in the dispersion auto-analysis now shows all columns.
        * Removed the temporary FIXMEs from the relax_disp.exp_type user function backend.  This is needed to enable the mixed experiment type code to be developed further, but means that the relax_disp branch will be broken for a while.
        * The specific_analyses.relax_disp.disp_data.loop_point() function now requires the exp_type argument.  The exp_type can no longer be determined within the loop_point() function.  Therefore it must be specified using a function argument.  The rest of the module has been updated for this change.
        * Updated specific_analyses.relax_disp.parameters.param_num() for the relax_disp.exp_type changes.
        * Fix for the Relax_disp.test_dpl94_data_to_dpl94 system test.  The experiment type is now set for the reference spectrum.
        * Created the new specific_analyses.relax_disp.checks module.  This contains many check_*() functions for raising RelaxErrors to tell the user when something is wrong.  This will be used to simplify, make more consistent, and fix cdp.exp_type errors in the dispersion code.
        * Added a number of auxiliary functions to specific_analyses.relax_disp.disp_data.  These are get_curve_type(), has_exponential_exp_type(), and has_fixed_time_exp_type() and will be used to simplify the dispersion code.
        * Fixes for the specific_analyses.relax_disp.api module for the relax_disp.exp_type change.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.  The loop_exp*() functions are now being used throughout the module.  The specific_analyses.relax_disp.checks.check_*() functions are also used to simplify the code and fix changes to cdp.exp_type.  And some auxiliary functions from specific_analyses.relax_disp.disp_data are being used as well.
        * Added some functions to specific_analyses.relax_disp.disp_data for checking if certain experiments exist.  These are the has_cpmg_exp_type() and has_r1rho_exp_type() functions.
        * The dispersion auto-analysis no longer references cdp.exp_type.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.
        * Fix for the new loop_exp_frq() dispersion function.
        * A few fixes for the relax_disp.exp_type user function changes.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.
        * Fixes for the specific_analyses.relax_disp.disp_data.find_intensity_keys() function.  This is for the cdp.exp_type changes.
        * Fixes for the relax_disp.plot_disp_curves user function backend for the cdp.exp_type changes.
        * A number of fixes for the relax_disp.exp_type user function changes.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.
        * Updated the Hansen CPMG data relax save files for the cdp.exp_type changes.
        * Fix for the Relax_disp.test_hansen_cpmgfit_input system test for a new set of errors.  The Hansen R2eff values have been recalculated and the errors are now slightly different.
        * More fixes due to the cdp.exp_type change.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.
        * Updated the r1rho_off_res_tp02 dispersion system test data for the cdp.exp_type changes.
        * Some more fixes for the cdp.exp_type now being dependent on the spectrum ID.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.
        * Changes so that the target function will handle multiple experiment types.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.  The data structures from return_r2eff_arrays() now have an additional dimension.  The new first dimension is that of the experiment type.  This affects the values, errors, and missing data structures.  This dimension is stripped in the dispersion target function class for the single experiment type models, but will be preserved for the combined models to be added in the future.
        * The spectrum list GUI element is now more robust to missing data.  The cdp.spectrum_ids data structure no longer needs to exist.
        * The peak intensity wizard requires more than 10 pages.  The hardcoded limit of a maximum of 10 wizard pages has been increased to 15.  Due to the non-linearity for the wizard pages, not all are seen, but many pages are required.
        * The spectrum list GUI element can now handle the cdp.exp_type data structure not existing.
        * Fixes for all of the specific_analyses.relax_disp.disp_data.has_*_exp_type() functions.  They now operate when no experiment types have been specified.
        * Redesigned the peak intensity loading GUI wizard for handling multiple experiment types.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.  The logic for the page ordering needed to be changed to be more dynamic.  The CPMG and R1rho pages need to be shown only if the corresponding experiment type exists in the current data pipe.  Hence the has_cpmg_exp_type() and has_r1rho_exp_type() dispersion functions are now used by the new methods wizard_page_after_relax_time() and wizard_page_after_cpmg_frq().  A number of now useless flags have also been removed.
        * Added some sanity checks to the dispersion target function class.  R1rho models cannot be used with CPMG-type experiments, and CPMG models cannot be used with R1rho-type experiments.
        * Fixes for all of the GUI dispersion tests for the changes to cdp.exp_type.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.
        * Large speed up of the Relax_disp.test_tp02_data_to_tp02 GUI test.  By minimising the number of times the peak intensity wizard pages are regenerated, the test time decreased on one system from ~32s to ~12s.
        * Simplified the code of the Relax_disp.test_hansen_trunc_data GUI test.
        * The GUI now warns if the user choses inappropriate models.  When clicking on 'Execute', an error message appears if R1rho models are selected for CPMG data and vice versa.  This is simply for more intuitive user feedback.
        * Fix for the relax_disp.exp_type pop up menu entry in the spectrum list GUI element.  This was calling relax_fit.exp_type rather than relax_disp.exp_type.
        * Fix for the relax_disp.cpmg_frq pop up menu entry in the spectrum list GUI element.  The method associated with the menu entry action_relax_disp_cpmg_frq() was buggy.
        * Fix for the relax_disp.spin_lock_field pop up menu entry in the spectrum list GUI element.  Another action method bug - the same as in the last commit.
        * Added two functions for determining if a spectrum ID corresponds to a CPMG or R1rho experiment.  These are functions in specific_analyses.relax_disp.disp_data and they are called is_cpmg_exp_type() and is_r1rho_exp_type().
        * Big redesign of the spectrum list GUI element for the dispersion analysis.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/4530, the thread about supporting multiple data types such as SQ+MQ data simultaneously.  The popup menu must be generated on the fly, as the CPMG frequency and spin-lock field strength menu entries should only be shown for the appropriate experiment type.  Therefore the new generate_popup_menu() method has been added to the gui.components.base_list GUI element.  The flags sent into the spectrum list GUI element have also been completely changed to now indicate the analysis type directly.
        * Expanded the Relax_disp.test_hansen_trunc_data GUI test to check the spectrum list GUI element.  The popup menu is now tested with the Fake_right_click() trick.  And the actions of a number of the menu items, the action*() methods, are tested to see if the user functions are correctly called.
        * Modified many of the spectrum list GUI element action_*() methods for the GUI tests.  These now take the 'item' keyword argument which overrides the ListCtrl.GetFirstSelected() call.  This ListCtrl call cannot be reliably simulated on all operating systems, so the item keyword argument can be used to explicitly select list items.
        * Fix for setting the relaxation time in the spectrum list GUI element for the dispersion analysis.  The popup menu item was calling the relax_fit.relax_time user function and not relax_disp.relax_time.
        * Fix for the action_relax_disp_cpmg_frq() method of the spectrum list GUI element.  The relax_disp.cpmg_frq user function was being incorrectly called.  This was identified via the Relax_disp.test_hansen_trunc_data system test.
        * Modified the Relax_disp.test_tp02_data_to_tp02 GUI test to check the spectrum list GUI element.  The popup menu is now tested in the same way as in the Relax_disp.test_hansen_trunc_data GUI test.
        * Modified the spectrum list GUI element action_relax_disp_spin_lock_field() method for the GUI tests.  This now accepts the optional 'item' keyword argument like the other action_*() methods.
        * Bug fix for the spectrum list GUI element popup menu relax_disp.spin_lock_field entry.  This was calling the relax_disp.spin_lock_field user function incorrectly.  The bug was identified by the Relax_disp.test_tp02_data_to_tp02 system test.
        * Fix for the Mf.test_auto_analysis GUI test due to the spectrum list GUI element changes.  The Fake_right_click() class now needs a GetPosition() method.
        * Moved the experiment type setting into per spectra settings.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fixed typo.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added the truncated test data for system test: relax -s Relax_disp.test_kteilum_fmpoulsen_makke_cpmg_data_to_cr72.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Created a relax save file with just R2eff values for the r1rho_on_res_m61 dispersion system tests data.
        * Created 3 new dispersion system tests.  These are for checking a new function that doesn't exist yet.  The get_curve_type() function will be used to determine if the experiment corresponding to the given ID consists of exponential curves or of fixed time data.
        * Fixed values for system test: relax -s Relax_disp.test_kteilum_fmpoulsen_makke_cpmg_data_to_cr72.  The test now passes.  The values are compared to a relax run with 500 Monte Carlo simulations.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added "CR72 full" test suite for kteilum_fmpoulsen_makke_cpmg_data.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added file which setup a truncated spin system.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Changed the initialization script to use the truncated spin system.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Changed the saved states to the truncated spin system.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix for the residue index in the test suite when using the truncated spin system.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * The R2eff result save file for the r1rho_on_res_m61 dispersion data now contains the full data set.  The previous file did not contain the full exponential curves.
        * The get_curve_type() function now works with the spectrum ID.  This specific_analyses.relax_disp.disp_data.get_curve_type() function already existed but it operated on all the loaded data.  Now it can handle a single spectrum ID.  The count_relax_times() function has been added to aid get_curve_type().
        * The get_curve_type() function is now imported into the dispersion system test module.
        * Modified the Relax_disp.test_dpl94_data_to_dpl94 system test.  This is in preparation for another relax_disp.exp_type change - the fixed and exponential parts will be dropped as this can be determined automatically by relax.
        * Changed the relax_disp.exp_type user function front end.  The supported types will now be 'CPMG' and 'R1rho', as the fixed time verses full exponential curve can be automatically determined by relax from what the user inputs.
        * Started a system test for model TSMFK01.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Modified the script for the full analysis of all models of CPMG type.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Simplified the dispersion experiment type classes.  The supported types will now be 'CPMG' and 'R1rho', as the fixed time verses full exponential curve can be automatically determined by relax from what the user inputs.  The EXP_TYPE_* dispersion variables have all changed and many have now been lost.  To support the changes, the new specific_analyses.relax_disp.disp_data.loop_spectrum_ids() function has been created.  This is a loop over all spectrum IDs whereby the experiment type, magnetic field strength, dispersion point, or relaxation time can be specified to isolate ID subsets.  Many of the specific_analyses.relax_disp.checks.check_*() has also been modified as their logic no longer works.  The auxiliary get_times() function has been added to create a per-experiment dictionary of relaxation times so that the checks can be independent of the other dispersion modules.
        * Updated much of the dispersion test data.  The experiment type has been changed in all the scripts and the relax save files updated.
        * Fixed expydoc formatting.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Created some more specific_analyses.relax_disp.checks.check_*() functions.  This is for better checking of the dispersion data.  The check_spectra_id_setup() is useful for checking that all of the spectrum information is set up.
        * The checks prior to minimisation of the dispersion models is now more comprehensive.
        * Bug fixes for the specific_analyses.relax_disp.checks.get_times() function.  The function is now more tolerant if certain data has now been set up yet.
        * Fixes for some of the R1rho dispersion system test scripts.  The relaxation time must be set for the reference spectrum.
        * Fixes for the Relax_disp.test_exp_fit system test - the spectrometer frequency is now set.  This information is now compulsory.
        * Converted references of ka and kA to k_AB.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Updated the CPMG dispersion analysis sample script for the relax_disp.exp_type user function changes.
        * Updated the user manual for the relax_disp.exp_type user function changes.  The script in the prompt/script UI section of the dispersion chapter needed to be updated.
        * Referencing fixes for the dispersion chapter of the user manual.
        * Updated the scripts and save files for the KTeilum_FMPoulsen_MAkke_2006 dispersion data.  This is for the recent relax_disp.exp_type user function changes and this allows the tests to pass.  Information on how to run the scripts and tee the output to logs has been added, and the logs added to the repository.
        * Added k_AB to parameters.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * More fixes for the relax_disp.exp_type user function changes.
        * The relaxation dispersion GUI elements now use the lib.text.gui module for Unicode strings.
        * Some Unicode text fixes in the dispersion GUI analysis for older MS Windows versions.
        * Updated the Grace string for the k_AB parameter - it was being shown as kA.
        * Fix for the model list in the GUI - the TSMFK01 model entry was broken.
        * Increased the size of the dispersion model list GUI window so that all models fit without scrolling.
        * Refinement of the dispersion model list in the GUI.  Descriptions have been added and the fixed window size adjusted to the best fit.
        * Modified system test after inclusion of 1M GuHCl dataset.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Moved files into folder which is specific for the experiment.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Changed scripts after moving data.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Re-run of data after movement of scripts.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added dataset experiment in 1.01 M GuHCl (guanidine hydrochloride).  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added to the README file for the 1.01 M GuHCL experiment.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Modified doc string for the script analysing all models for residue L61.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added the output from relax after analysis of all models.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Removed the size variable from the dispersion model list GUI window as it is no longer used.
        * Added the k_AB and k_BA conversion equations to the dispersion parameter table in the user manual.
        * Changed reference to Tollinger et al. instead of Tollinger/Kay.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fixes for the dispersion GUI tests for the changes to the model list GUI element.
        * Added the button for the interatom.define user function in preparation for the MQ dispersion data.  This is in the dispersion tab of the GUI.
        * The return_cpmg_frqs() and return_spin_lock_nu1() functions now return numpy arrays.  These are functions from specific_analyses.relax_disp.disp_data.
        * Speed ups for the optimisation of all of the R1rho dispersion models.  The spin-lock field strength data structure is now converted from Hz to rad.s^-1 in the dispersion target function initialisation.  Previously the conversion was happening multiple times per target function call.  This has a noticeable effect on the test suite timings.
        * Some small speed ups for the TP02 R1rho dispersion model optimisation.  Some unneeded calculations and aliases were removed.
        * Added the write-out of 'dw' and 'k_AB' for model TSMFK01, when performing auto-analysis.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added to calculate the tau_cpmg times when model is TSMFK01.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Optimized the target function for model TSMFK.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added the conversion to k_AB from kex and pA.  k_AB = kex * (1.0 - pA).  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Some more speed ups for the R1rho dispersion models.  For many models, the square of the spin-lock field strength is a part of the equations.  Therefore this is now pre-calculated when the target function is initialised.
        * Added the relaxation dispersion documentation to all of the value user function documentation.
        * Fix for the CPMG dispersion sample script - the numeric solution model name was not correct.
        * Fix for the dispersion model list in the GUI - the R1rho models were mixed up.
        * Added a sample script for an off-resonance R1rho dispersion analysis.
        * Created the empty specific_analyses.relax_disp.optimisation module.  This will contain functions and other objects relating to the optimisation of the dispersion models.
        * Fixed bug, where kex to k_AB where not possible if the model does not contain parameter 'pA'.  The conversion is now skipped.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added the conversion to k_BA from kex and pA.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added system test for testing conversion to k_BA from kex and pA.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix for passing system test on Windows with Python 32.  Precision lowered by 2 decimals.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added system tests for conversion of kex to k_AB/k_BA for models where kex and pA is present.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Modified headers for scripts producing analysis for data which is full or truncated.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Created the dispersion default_value_doc object.  This table is needed for the value.set user function.
        * Huge speed win for the relaxation dispersion analysis - optimisation now uses the multi-processor.  The relaxation dispersion optimisation has been parallelised at the level of the spin clustering.  It uses Gary Thompson's multi-processor framework.  This allows the code to run on multi-core, multi-processor systems, clusters, grids, and anywhere the OpenMPI protocol is available.  Because the parallelisation is at the cluster level there are some situations, whereby instead of optimisation being faster when running on multiple slaves, the optimisation will be slower.  This is the case when all spins being studied in clustered into a small number of clusters.  It is also likely to be slower for the minimise user function when no clustering is defined, due to the overhead costs of data transfer (but for the numeric models, in this case there will be a clear win).  The two situations where there will be a huge performance win is the grid_search user function when no clustering is defined and the Monte Carlo simulations for error analysis.
        * Decreased the number of grid increments in the dispersion sample scripts from 21 to 11.  This is a much easier optimisation problem than the other analyses in relax, so 21 increments is an overkill.  It also takes far too long for some of the models due to the high number of parameters.
        * Removed a tonne of unused imports from the modules of the specific_analyses.relax_disp package.
        * Deselected most of the default dispersion models from the dispersion GUI model list.  Now only one analytic and numeric model is selected per experiment type.  This is to hint to the user that maybe they shouldn't just use all models.
        * Added desc. item for model TSMFK01.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added TSMFK01 to model overview table.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.

        * Updated the relax_disp_trunc.py script for Flemming Hansen's CMPG test data.
        * Started to create the relax_disp.catia_input user function.  The frontend has been written and a stub of a function for the backend.  The new specific_analyses.relax_disp.catia module has been created for this.
        * Created the Relax_disp.test_hansen_catia_input system test.  This is to check the output of the relax_disp.catia_input user function.
        * The relax_disp.catia_input user function now creates the main CATIA input file and all R2eff data files.
        * Created a script for converting Flemming Hansen's data into CATIA input files.  This is for checking the relax_disp.catia_input and relax_disp.catia_execute user functions.
        * Fix for the CATIA main execution file created by relax_disp.catia_input.  The CATIA DataDirectory needs a '/' at the end.
        * Improvements to the relax_disp.catia_input user function.  On top of general improvements, the global parameter and parameter set files are now created.
        * More improvements for the relax_disp.catia_input user function.  The output directory for CATIA results is now an argument for the main backend function.  This directory is now also created, as required by CATIA.
        * Implemented the relax_disp.catia_execute user function.  This is modelled on the palmer.execute user function.
        * The relax_disp.catia_input user function now has a GUI icon associated with it.
        * Added the CATIA input files generated by relax for Flemming Hansen's truncated CPMG data set.
        * Rearranged the numeric CPMG models in the dispersion model list in the GUI.
        * The main CATIA input file requires the chemical shifts and R1 values to be fixed, even when missing.  This is for the relax_disp.catia_input user function.
        * Added Tollinger reference.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Added Tollinger model TSMFK01 to sample scripts.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fixed several typo errors of "Is it selected"->"It is selected".  A copy-paste error which has spread.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Spacing fixes for the Tollinger01 Bibtex entry for the author initials.
        * Removed some strange characters from the Tollinger01 Bibtex abstract.
        * Fix for some inline references in the dispersion chapter of the user manual.
        * Enabled the parallelisation of Monte Carlo simulations for the relaxation dispersion analysis.
        * Created a set of scripts for testing out the multi-processor abilities of the dispersion analysis.
        * Added Remco Sprangers' truncated ClpP data to test_suite/shared_data/dispersion/Spranger_ClpP.  This is the data attached to https://gna.org/task/?7712#comment6, and it will be used for testing the implementation of the 'MQ NS 2-site' model, when added to relax.
        * Concatenated the peak intensity files.
        * Created a relax script for analysing Remco Sprangers' ClpP data with the 'MQ NS 2-site' model.  This currently does not work, as the model is absent.
        * Modified the dispersion auto-analysis to check if peak intensity errors have been pre-calculated.  This allows the user to perform custom analyses and the auto-analysis will then not overwrite these values.
        * Bug fixes for the averaging of peak intensity errors in the dispersion analysis.  This is in the specific_analysis.relax_disp.disp_data.average_intensity() function.
        * Fix for the docstring formula in lib.dispersion.two_point.calc_two_point_r2eff_err().
        * Updated the relax script for analysing Remco Sprangers' ClpP data with the 'MQ NS 2-site' model.  The error analysis has been removed as it is identical to what the auto-analysis does.
        * Renamed the directory of Remco Sprangers' CPMG dispersion data to correctly spell his name.
        * Updated the script for Remco Sprangers' MQ CPMG data.
        * Created the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test.  This checks the 'MQ NS 2-site' model against Remco Sprangers' MQ CPMG data using the auto-analysis.
        * Fixes for the checks of the new Relax_disp.test_sprangers_cpmg_data_auto_analysis system test.  The 'MQ NS 2-site' model checks were still set up to those of the Relax_disp.test_hansen_cpmg_data_auto_analysis system test.
        * Added the 'MQ NQ CPMG 2-site' model to the dispersion variables.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Adding_the_model_to_the_list The new dispersion variable MODEL_MQ_NS_CPMG_2SITE has been added.  As this is a new data type, multi-quantum CPMG, the new MODEL_LIST_MQ_CPMG and MODEL_LIST_MQ_CPMG_FULL lists have been created.
        * Rearranged the documentation for the relax_disp.select_model user function to simplify the text.
        * Created the lib.text.gui.dwH Unicode string for use with the 'MQ NS 2-site' dispersion model.
        * Added the 'MQ NS CPMG 2-site' model to the relax_disp.select_model user function frontend.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_front_end Two new sections were added to the user function docstring for the MQ CPMG and MQ R1rho experiment types.
        * Added support for the 'MQ NS CPMG 2-site' model to the relax_disp.select_model user function back end.  This is the numeric solution for 2-site exchange for multi-quantum CPMG-type data.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_back_end.
        * Added support for the new 'dwH' dispersion parameter.  This is needed for the 'MQ NS CPMG 2-site' model support.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Adding_support_for_the_parameters.
        * Improved the RelaxError from the relax_disp.exp_type user function when an invalid experiment type is set.
        * Added the multi-quantum CPMG and R1rho experiment types to the dispersion variables.  This is needed for the 'MQ NS CPMG 2-site' model.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Creating_a_new_experiment_type.
        * Added relaxation dispersion model lists for the MQ R1rho models.  These are stubs as no MQ R1rho models are yet supported by relax.
        * Added support for the MQ dispersion data type to the specific_analyses.relax_disp.disp_data module.  This is needed for the 'MQ NS CPMG 2-site' model.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Creating_a_new_experiment_type.
        * Added support for the MQ dispersion data types to the rest of relax.  This is needed for the 'MQ NS CPMG 2-site' model, and the changes affect the dispersion data checks and the dispersion target functions.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Creating_a_new_experiment_type.
        * Updated the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test for 'MQ CPMG' data.  This also affects the script in the shared_data test suite directory.  The relax_disp.exp_type user function exp_type argument has been changed from 'CPMG' to 'MQ CPMG'.
        * Updated the relax_disp.exp_type user function for the new 'MQ CPMG' and 'MQ R1rho' experiment types.  This is needed for the 'MQ NS CPMG 2-site' model.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Creating_a_new_experiment_type.
        * Created the 'MQ NS CPMG 2-site' model target function.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_target_function.
        * Added the 'MQ NS CPMG 2-site' R1rho calculating function to the relax library.  This is the 2-site numeric solution for multi-quantum CPMG-type data.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_library.
        * Updated the 'MQ NS CPMG 2-site' model target function to match the function in the relax library.
        * Decreased the grid increments in the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test.  This is to speed up this test.
        * Some small changes for the script for optimising Sprangers' ClpP MQ CPMG data.
        * Added the 'MQ NS CPMG 2-site' model to the dispersion auto-analysis.  This is the 2-site numeric solution for multi-quantum CPMG-type data.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_auto-analysis.
        * Added the 'MQ NS CPMG 2-site' model to the GUI model list.  This is the 2-site numeric solution for multi-quantum CPMG-type data.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_GUI.
        * Rearranged the 'Implemented models' subsection of the dispersion chapter of the manual.
        * Fixed the 'MQ NS CPMG 2-site' model description in the relax_disp.select_model user function.  The magnitisation vector is 2D, not 3D.
        * Added a latex definition for the dwH dispersion parameter and added the 'MQ' abbreviation.
        * Added the 'MQ NS CPMG 2-site' model to the relax user manual.  This is the 2-site numeric solution for multi-quantum CPMG-type data.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_manual.
        * Simplified the 'MQ NS CPMG 2-site' model code in lib.dispersion.
        * Fixes for the 'MQ NS CPMG 2-site' model equations in the user manual.
        * Rearrangements of the tables in the dispersion chapter of the user manual.  The tables have been shifted out into their own LaTeX files, and all dispersion model tables have been concatenated into one.
        * Edited the MQ abbreviation in the user manual.
        * Fixed some bad referencing in the dispersion chapter of the manual.
        * Docstring fix for the lib.dispersion.mq_ns_cpmg_2site.populate_matrix() function.
        * Fix for a bug in the specific_analyses.relax_disp.disp_data.loop_point() function introduced at r21060.
        * Speed ups for the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test.  This test does not pass yet, but this should allow the test to complete in under an hour.
        * Added some value.set user function calls to the script for Sprangers' ClpP data.
        * Added some value.set calls to the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test.  These user function calls will be used to test a new concept of fixing parameters in the grid search.  The dw and dwH parameters are fixed to the experimental values, as described in the README file from Remco Sprangers (in test_suite/shared_data/dispersion/Sprangers_ClpP).
        * Changed the operation of the grid search for the relaxation dispersion analysis.  If a parameter is a simple floating number type and it already has a value, then the grid search over that dimension is fixed.  The grid increments are set to 1, and the upper and lower bounds set to the parameter value.  This allows parameters to be pre-set, if known from experiment.  They will nevertheless be optimised via the minimise user function.
        * Added a printout for the pre-set dispersion parameter skipping in grid search.
        * Updated the dispersion grid search function to user the loop_parameters() function.  This is an important fix as the specific_analyses.relax_disp.optimisation.grid_search_setup() function was not matching the rest of the dispersion code, hence the parameters of the grid increments and bounds were not matching the parameter vector, scaling matrix, target function parameter depacking, etc.
        * A bit of help for some of the R1rho dispersion model system tests.  These now fail after a fundamental fix.  The problem is only due to the very coarse grid search size - a finer grid search allows the solution to be correctly found.  However as this is far too slow, instead the kex parameter is set to be close to the solution to skip a grid search dimension.
        * Some basic fixes for the Relax_disp.test_hansen_catia_input system test.  The relax_disp.catia_input user function is not complete, but this allows the Relax_disp system tests to pass.
        * The dispersion multi-processor optimisation code now prints out its own simulation messages.  This is to fix bug #21190 (https://gna.org/bugs/?21190).  The memo object now is feed in the spin IDs of the cluster and stores this as the cluster_name variable.  This is used by the results object run() method, which is run on the master at the end, to print out a message along the lines of "Simulation X, cluster yyy".  Therefore the message is only printed out once the calculation of that slave command is complete and returned to the master.
        * Replaced all usage of scipy.linalg.expm() with lib.linear_algebra.matrix_exponential.matrix_exponential().  This is for the functions of the lib.dispersion package used for the relaxation dispersion numeric solution models.  The change eliminates a bug in the scipy function which uses the Pade approximation which fails horribly for the complex part of the matrix.  The real part looks good, but the complex part looks to have nasty truncation artefacts which is propagated and amplified through the Bloch-McConnell equations.
        * Modified the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test so the models are programatically changed.
        * Changes to the Sprangers ClpP data analysis script.
        * Simplified the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test script.  The pA and kex parameters are now also pre-set to speed things up.
        * Added a script and results files for the base 'R2eff' model for Remco Sprangers' ClpP data.
        * Fixes for the R2eff data files for Sprangers ClpP data.
        * Artificially increased the errors in Sprangers ClpP data to match the publication.  The R2eff errors are simply multiplied by 5, as the errors from the paper cannot be replicated.
        * Converted the Relax_disp.test_sprangers_cpmg_data_auto_analysis system test to not use the auto-analysis.  The test has been renamed to Relax_disp.test_sprangers_data_to_mq_ns_cpmg_2site.  The optimisation is now for the cluster and has been severely cut back.  The 'MQ NS CPMG 2-site' model appears to be rubbish anyway - it looks to be indeterminate with multiple solutions, and possibly infinite lines of solutions.  The test now passes, and quickly.
        * Created the Relax_disp.test_sprangers_data_to_mq_cr72 system test.  This was copied from the Relax_disp.test_sprangers_data_to_mq_ns_cpmg_2site system test and the model changed to 'MQ CR72'.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_test_suite.
        * Added the 'MQ CR72' model to the dispersion variables.  This is the Carver and Richards (1972) 2-site model expanded for MQ CPMG data by Korzhnev et al., 2004.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Adding_the_model_to_the_list.
        * Added the 'MQ CR72' model to the relax_disp.select_model user function frontend.  This is the Carver and Richards (1972) 2-site model expanded for MQ CPMG data by Korzhnev et al., 2004.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_front_end.
        * Added support for the 'MQ CR72' model to the relax_disp.select_model user function back end.  This is the Carver and Richards (1972) 2-site model expanded for MQ CPMG data by Korzhnev et al., 2004.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_back_end.
        * Created the 'MQ NS CPMG 2-site' model target function.  This is the Carver and Richards (1972) 2-site model expanded for MQ CPMG data by Korzhnev et al., 2004.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_target_function.
        * Added the 'MQ CR72' R2eff calculating function to the relax library.  This is the Carver and Richards (1972) 2-site model expanded for MQ CPMG data by Korzhnev et al., 2004.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_library.  The corresponding target function was updated to input the correct arguments.
        * Added the 'MQ CR72' model to the dispersion auto-analysis.  This is the Carver and Richards (1972) 2-site model expanded for MQ CPMG data by Korzhnev et al., 2004.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_auto-analysis.
        * Added the 'MQ CR72' model to the GUI model list.  This is the Carver and Richards (1972) 2-site model expanded for MQ CPMG data by Korzhnev et al., 2004.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_GUI.
        * A number of fixes for the lib.dispersion.mq_cr72 module.
        * The lib.dispersion.mq_cr72 module now more closely resembles the cr72 module in syntax.
        * Added a relax script for the 'MQ CR72' model optimised using Flemming Hansen's CPMG data.  This is to demonstrate, though not exactly successfully, that the 'MQ CR72' model can collapse to the 'CR72' model.  The imperfection might be due to truncation artefacts in the sin ratio in the mD and mZ factors.  The results files and output log file from the script have been added to the repository as well.
        * Updates for the script and results for the 'MQ CR72' model optimised using Flemming Hansen's CPMG data.
        * Added a script and results files for optimising Sprangers' ClpP MQ CPMG data to the 'MQ CR72' model.
        * Bug fix for the dispersion specific loop_parameters() function for the multiple quantum models.  The dw and dwH parameters were being interleaved rather than all dw for all spins first and then all dwH.  The result was that these parameters were being mixed up in the MQ model target functions when clustering was activated, causing total failure of the MQ models.
        * Added a script and results files for optimising Sprangers' ClpP MQ CPMG data to the 'MQ CR72' model.  This is with all spins clustered.  It complements the files which are used for the pre-run results of the auto-analysis.
        * Better spacing in the model table of the relaxation dispersion chapter of the relax manual.
        * Added the Tollinger et al., 2001 reference for the 'NS CPMG 2-site expanded' model.  This reference was communicated in a private email.
        * Improvements for the LaTeX maths commands used in the dispersion chapter of the user manual.
        * Added Skrynnikov and Tollinger to the copyright notice in lib/dispersion/ns_cpmg_2site_star.py.  I can now see that the code derives from the funNumcpmg.m of the sim_all.tar file (https://gna.org/support/download.php?file_id=18404) attached to https://gna.org/task/?7712#comment5.  This sim_all.tar file is the original code of Nikolai and Martin.
        * Modified the relaxation dispersion auto-analysis to take nesting of MQ models.  This is specifically the nesting of the analytic 'MQ CR72' model and the 'MQ NS CPMG 2-site' models.  The analytic solution is now used as the optimisation starting point for the numeric model.
        * Used the \imath LaTeX symbol for complex numbers in the dispersion chapter of the manual.
        * Added scripts and results for optimising Sprangers' ClpP MQ CPMG data to the 'MQ NS CPMG 2-site' model.  This includes two scripts for non-clustered followed by clustered analysis using the 'MQ CR72' model in the auto-analysis so its parameters will be used as the optimisation starting point for the 'MQ NS CPMG 2-site' model.  The results files for both scripts have been added to the repository.
        * Added the 'MQ CR72' model to the relax user manual.  This is the Carver and Richards (1972) 2-site model expanded for MQ CPMG data by Korzhnev et al., 2004.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_manual.
        * Modified the dwH symbol in the relax user manual.
        * Created a 'TODO' section in the dispersion chapter of the relax user manual.  This lists all of the features and models currently missing from the dispersion analysis in relax.
        * Added the original Maple script to the lib.dispersionns_cpmg_2site_expanded module docstring for reference.  This was sent by Nikolai in a private communication.
        * More expansion of the lib.dispersionns_cpmg_2site_expanded module docstring for reference.  The link https://gna.org/task/?7712#comment8 to the p3.analytical script in the Gna! tasks has been added and the contents of the sim_all.tar file funNikolai.m has been copied into the docstring as well.
        * Epydoc docstring fixes to allow the API documentation to be properly compiled.
        * Python 3 fix for the lib.dispersion.mq_ns_cpmg_2site module.  The numpy.linalg.matrix_power requires an integer power, but Python 3 was creating a floating point number for the 'fact' variable.
        * Updated the Relax_disp.test_sprangers_data_to_mq_cr72 system test so it passes.  The parameters found in the analysis located in the directory test_suite/shared_data/dispersion/Sprangers_ClpP/mq_cr72_analysis_clustered have been used as the starting point.
        * A number of Python 3 fixes.
        * Python 3 fixes for the dispersion data key generation and the data assembly.  The specific_analyses.relax_disp.disp_data.return_param_key_from_data() function was generating different keys for Python 2 and 3.  This has been fixed.  The return_r2eff_arrays() function has also been modified to correctly check for these keys.
        * Removed an insanely large log file from the Flemming Hansen dispersion data directories.  This is the log file for the CPMGFit analysis.
        * A large number of fixes for the relaxation dispersion system tested needed for the fix which changed the format of the keys by which the R2eff/R1rho data is accessed.
        * Updated the Relax_disp.test_sprangers_data_to_mq_ns_cpmg_2site system test to allow it to pass.
        * Created the new Relax_disp.test_hansen_cpmg_data_auto_analysis_numeric system test.  This will be used to test a new feature whereby pure numeric models will be used in the auto-analysis.
        * Added the model_class variable to the relaxation dispersion auto-analysis class.
        * Changed the new dispersion auto-analysis class variable model_class to the numeric_only flag.
        * Created list variables of all analytic and numeric dispersion models.  These are the MODEL_LIST_ANALYTIC and MODEL_LIST_NUMERIC lists in the module specific_analyses.relax_disp.variables.
        * Fix for the hansen_data.py dispersion auto-analysis script used for a number of system tests.  The numeric_only flag was not being handled correctly.
        * Implemented the numeric only option for the dispersion auto-analysis.  If the numeric_only flag is set to True, then no analytic models will be used in the final model selection.
        * Completed the Relax_disp.test_hansen_cpmg_data_auto_analysis_numeric system test.  This now checks all the optimised parameter values and makes sure that no 'CR72' model was selected.
        * Added a new button to the button bar in the relaxation dispersion GUI analysis tab.  This is a button used to launch the value.set user function to allow the user to pre-set certain parameters so that they are not used in the grid search.
        * Created a GUI element for the numeric_only flag of the auto-analysis for the dispersion GUI tab.  This defaults to false to allow all model types to be used.
        * Loosened the Relax_disp.test_sprangers_data_to_mq_ns_cpmg_2site system test to allow it to pass on Mac OS X.
        * Fixes to allow the Mf.test_mf_auto_analysis system test to pass on Mac OS X.  The simulated event.GetPosition() method in the Fake_right_click class the file test_suite/gui_tests/model_free.py must return a wx.Point object and not a Python tuple.  The gui.components.base_list.Base_list.on_right_click() method has also been modified with a wx.Yield() call to allow the test to pass.
        * Loosened some of the relaxation dispersion system tests to allow them to pass on MS Windows.
        * Commented out some checks of the Relax_disp.test_hansen_cpmg_data_auto_analysis_numeric system test.  This is to allow this test to pass on 32-bit GNU/Linux systems.  The numeric model optimisation is incomplete but different between the 32-bit and 64-bit systems.
        * Fix for the relaxation dispersion system test tearDown() method.  The rmtree function is no longer user, rather the test_suite.clean_up.deletion() function is being used to handle the issue of MS Windows not releasing the file in time.
        * Fix for the test_suite.clean_up.deletion() method for another MS Windows problem.  Sometimes the failed rmtree() call actually deletes the files and throws the WindowsError error.  Therefore the second rmtree() call will throw another WindowsError for the missing files.  This is now caught.
        * Elimination of the relaxation dispersion system test tearDown() method.  The functionality is fully covered by the base system test method.
        * Shifted all of the numerical dispersion code to use the internal matrix power function.  Instead of using the numpy.linalg.matrix_power() function, the relax lib.linear_algebra.square_matrix_power() function is being used instead.  This allows the code to run on many older systems, as the numpy function is relatively new.
        * Updated the Relax_disp.test_hansen_cpmg_data_to_ns_cpmg_2site_star_full system test.
        * Fix for the lib.dispersion.cr72 module for early Python versions.  For Python 2.5 and earlier, the math.acosh() function does not exist.  Therefore the numpy equivalents are now being used.
        * Loosened the checks for the Relax_disp.test_hansen_cpmg_data_to_ns_cpmg_2site_star_full system test.  This is to allow the test to pass on 32-bit Linux systems.
        * Caught a divide by zero in the specific_analyses.relax_disp.disp_data.return_offset_data() function.  This was identified by turning all numpy warnings to errors.
        * More loosening of the Relax_disp.test_hansen_cpmg_data_to_ns_cpmg_2site_star_full system test.  This is now for 64-bit Mac OS X to pass.
        * The dispersion GUI analysis cluster_update() method is now thread safe.  This removes many error messages when running the dispersion analysis in the GUI, especially for Mac OS X systems.
        * The dispersion data return_cpmg_frqs() and return_spin_lock_nu1() functions are now safer.  These specific_analyses.relax_disp.disp_data module functions can now be called when no data is present.
        * Fixes for the calc user function for the dispersion analysis.  This now does something logical for the non-R2eff models.  The chi-squared value is now being calculated and stored.  Previously this was only calculating the R2eff/R1rho values for fixed relaxation time period data for the 'R2eff' model and failing for all others.  Now the pre-existing _back_calc_r2eff() method is used to back-calculate and store the chi-squared value.
        * Redesigned the Relax_disp.test_hansen_cpmg_data_to_ns_cpmg_2site_star_full system test.  The R2A and R2B rates cannot be distinguished for this data, therefore there was no unique solution.  This resulted in too much variability between 32 and 64-bit systems as well as different operating systems.  Instead a single calc user function call is used to determine the chi-squared value for a fixed set of parameters.
        * Loosened the test_hansen_cpmg_data_to_ns_cpmg_2site_star_full system test for Mac OS X.  Even the calc user function does not help, the results are quite different between different systems.
        * The specific API calculate_r2eff() method for the dispersion analysis is now private.  This is not part of the API, so it must be made private for the test suite to pass.
        * Fix for the Mf.test_mf_auto_analysis system test on MS Windows.  The Fake_right_click.GetPosition() method now returns a valid position.  This is the original (10, 10) position.
        * Fix for a bug introduced earlier - the call to the calculate_r2eff() must also be made private.
        * Fixes for 2 Relax_disp GUI tests to match the previous model-free fixes.  The Fake_right_click.GetPosition() method now returns a wx.Point object.
        * Added test data where both the spin-lock time, the spin lock offset and the spin lock field is varied.  The data is published in "Kjaergaard, M., Andersen, L., Nielsen, L.D. & Teilum, K. (2013).  A Folded Excited State of Ligand-Free Nuclear Coactivator Binding Domain (NCBD) Underlies Plasticity in Ligand Recognition.  Biochemistry, 52, 1686-1693" with experimental conditions that "off-resonance R1rho relaxation dispersion experiments on 15N were recorded at 18.8 T and 31 C." and "using the pulse sequence of Mulder et al. with spin-lock field strengths from 431 to 1649 Hz and offsets ranging from 0 to 10000 Hz."
        * Shifted the 'NS CPMG 2-site expanded' model to the top of the CPMG numerical solutions in the manual.  This is because this is the default model which should be used in most cases.
        * A 20-25% speed increase for the 'NS CPMG 2-site expanded' dispersion model.  Many repetitive mathematical operations have been eliminated and the equations have been changed to optimise the calculation speed.
        * Modified settings script for R1rho test dataset.
        * Fix for the amsmath LaTeX package in the user manual.  It needs to be after the hyperref package, as hyperref clobbers a number of amsmath features.
        * Added all of the equations for the 'NS CPMG 2-site expanded' dispersion model to the relax manual.  These are essentially the source code modified to look good in LaTeX.
        * Fix for the 'NS CPMG 2-site expanded' model equations in the manual.
        * Better section spacing in the dispersion chapter of the manual.  Each model section is now on a new page.
        * Fix for the display of the spin-lock nu1 values in the dispersion GUI tab.  This was reported by Troels at http://thread.gmane.org/gmane.science.nmr.relax.devel/4708.  The GUI spectrum element at gui.components.spectrum was at fault, the add_disp_point() method was buggy.
        * Fix for the right click pop up menu entry "Set the spin-lock field" in the dispersion GUI tab.  This is for the spectra list relax_disp.spin_lock_field user function call.  The reference spectra are now detected and the field value set to None.  This fix has been propagated to the relax_disp.cpmg_frq user function menu entry as well.
        * Correcting the R1rho settings script for the right calculation of the spin-lock offset, omega_rf, in ppm when offset values are provided in Hz.
        * Added ZQ and DQ data to the TODO list in the dispersion chapter of the manual.
        * Fix for the relaxation dispersion specific private _cluster_ids() method.  This was identified at http://thread.gmane.org/gmane.science.nmr.relax.devel/4716.  The cluster data structure was not being referenced correctly.
        * Added some lines to the end of the script UI section of the dispersion chapter about custom protocols.
        * Added a new section to the dispersion chapter of the manual for comparing different dispersion software.  This is an expansion of the table in the paper draft.
        * Updates for the dispersion software comparison section of the user manual.
        * Bug fix for the 'MQ NS CPMG 2-site' model.  This was found with the aid of private feedback from Dmitry Korzhnev and him emailing his cpmg_fitd9 program.  The problem is that he defines the 'n' parameter as half of a CPMG block.  The code was however assuming that 'n' is a full CPMG block.
        * Added ZZ exchange as a missing feature to the dispersion chapter of the manual.
        * Added Dmitry Korzhnev's Fyn SH3 domain data for Asp 9 to the repository.  This is from Dmitry M. Korzhnev, Philipp Neudecker, Anthony Mittermaier, Vladislav Yu. Orekhov, and Lewis E. Kay (2005)  Multiple-site exchange in proteins studied with a suite of six NMR relaxation dispersion experiments: An application to the folding of a Fyn SH3 domain mutant.  127, 15602-15611 (doi: http://dx.doi.org/10.1021/ja054550e).  It consists of the 1H SQ, 15N SQ, ZQ, DQ, 1H MQ and 15N MQ data for residue Asp 9 of the Fyn SH3 domain mutant.
        * Added the results from Korzhnev's cpmg_fit program for the Asp9 Fyn SH3 dispersion data.
        * Created a relax state for the R2eff SQ data of Korzhnev et al., 2005.
        * Added printouts for the overfit_deselect() specific API method for the dispersion analysis.  This is to inform the user whenever spins are deselected and why.  This is to help avoid user confusion.
        * Started to add some preliminary dispersion results for the Korzhnev data.
        * Started the conversion of the 'MQ NS CPMG 2-site' model to 'MMQ 2-site'.  This follows from the post at http://article.gmane.org/gmane.science.nmr.relax.devel/4734.
        * Renamed all of the 'MQ NS CPMG 2-site' modules and functions for the change to 'MMQ 2-site'.  This follows from the post at http://article.gmane.org/gmane.science.nmr.relax.devel/4734.
        * Added the ZQ and DQ CPMG experiment types to the dispersion variables.  This is needed for the 'MQ NS CPMG 2-site' model change to 'MMQ 2-site' and follows from the post at http://article.gmane.org/gmane.science.nmr.relax.devel/4734.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Creating_a_new_experiment_type.
        * Created two new dispersion variables - EXP_TYPE_LIST_CPMG and EXP_TYPE_LIST_R1RHO.  This will be used to simplify identifying CPMG vs. R1rho data types.
        * Added support for the ZQ and DQ CPMG data type to the specific_analyses.relax_disp.disp_data module.  This is needed for the 'MQ NS CPMG 2-site' model change to 'MMQ 2-site' and follows from the post at http://article.gmane.org/gmane.science.nmr.relax.devel/4734.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Creating_a_new_experiment_type.
        * Completed the support for ZQ and DQ CPMG experiment types in relax.  This is needed for the 'MQ NS CPMG 2-site' model change to 'MMQ 2-site' and follows from the post at http://article.gmane.org/gmane.science.nmr.relax.devel/4734.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Creating_a_new_experiment_type.
        * The 'MMQ 2-site' model target function can now handle multiple CPMG data types.
        * Added dispersion curve plotting to the relax script for Korzhnev et al., 2005 MMQ data.
        * Turned off the dw, dwH > 0 constraint for the 'MMQ 2-site' model.
        * Added a page reference back to the intro chapter in the scripting section of the dispersion chapter.  This is to help the user work out how to run a relax script.
        * Fix for the sqrt() function in the dispersion parameter table.
        * Added a section to the dispersion chapter about spin clustering.
        * Removed most of the \clearpage commands in the dispersion chapter of the manual.  There was far too much whitespace.
        * Added a 600x600 pixel graphic for the spin cluster for use in the user manual.
        * Added the cluster graphic to the cluster section of the dispersion chapter and improved the text.
        * Proper handling of the back-calculated dispersion data for the new 'MMQ 2-site' model.
        * Shifted the optimisation printouts for the dispersion analysis out of the memo.  This improved the ordering of the printed out messages when running on a cluster.  Instead of having multiple optimisation printouts followed by a list of the corresponding optimised values, now they are interleaved as they should be.
        * Changed the definition of tex thanks to feedback from Nikolai Skrynnikov.  This was previously defined as tex = 1/(2kex) to be compatible with CPMGFit, but has now been changed to tex = 1/kex.
        * Converted the 'IT99' dispersion model parameters to pA and dw.  This is thanks to feedback from Nikolai Skrynnikov.  I have no idea why the phi_ex and pA.dw^2 parameters were being used in the first place.  The model results after the change are identical.
        * Fix for the optimised parameter printout - the parameters are now scaled.  This problem was only recently introduced.
        * The dispersion sample scripts now have the NUMERIC_ONLY boolean variable defined.
        * Decreased the number of models presented to the user in the dispersion sample scripts.
        * The model type is now being written to file for the final run of the dispersion auto-analysis.
        * Added the model_type spin variable to the dispersion analysis specific PARAMS data object.
        * Updated the text and Grace files output for the 'IT99' model in the dispersion auto-analysis.
        * Fixes for the output of the selected mode in the dispersion auto-analysis.  The correct variable is now used.
        * Proper fix for the printout of the optimised dispersion parameters.  The loop_parameters() dispersion function is no longer used, avoiding all requirements on the current data pipe existing.  This allows for proper printouts on a MPI cluster.
        * Added a page reference to the multi-processor section in the script section of the dispersion chapter.
        * Added residue 4 to the truncated CPMG data from Flemming Hansen for another test system.
        * Updated the CPMGFit results for Flemming Hansen's CPMG data truncated to 3 spins.
        * Updated the README file explaining how to convert the CPMGFit parameters to those of other software.
        * Updated the relax results for Flemming Hansen's CPMG data for the recent changes.
        * Updated the NESSY results for Flemming Hansen's data.  A number of improvements have been added to NESSY including being able top optimise residues with missing data sets.  A number of bugs have also been eliminated.
        * Updated the NESSY log for the bug fix of r1105 (in the NESSY repository).
        * Updated the ShereKhan results to include residue :4 and the ShereKhan numeric results.  The numeric model in ShereKhan was previously buggy and did not return results.  This has been fixed after I sent feedback to the authors.
        * Updated the software comparison document for a subset of Flemming Hansen's CPMG data.  This now includes residue 4, the changes in results for all software, new NESSY results due to fixes I made in NESSY, and the new results for numeric model in ShereKhan.
        * Added all of the new NESSY plots for the truncated Hansen CPMG data.
        * Fixes for all of the system tests using Flemming Hansen's CPMG data subset.  The errors are now different and the new residue 4 has to be deselected and ignored.
        * Created the new relax_disp.insignificance user function.  This will be used to deselect all spins whereby the maximum difference in all its dispersion curves is below a certain cutoff.
        * Improvements for the relax_disp.insignificance user function.  Text is now printed out when a spin is deselected.  And all spins set to the 'R2eff' model are skipped.
        * The relaxation dispersion auto-analysis now accepts the 'insignificance' argument.  This is then used in the relax_disp.insignificance user function prior to the optimisation of each model, so that spins with insignificant dispersion curves are not optimised.  The 'R2eff' and 'No Rex' models are skipped for obvious reasons.
        * Created an INSIGNIFICANCE variable for the relaxation dispersion sample scripts.  This is to allow the user to eliminate insignificant models.
        * Added the insignificance dispersion auto-analysis argument to the Hansen CPMG data optimisation script.
        * Updated script UI section of the dispersion chapter of the user manual.  This is for the recent changes to the sample scripts including the addition of the RESULTS_DIR and INSIGNIFICANCE variables.
        * Added the 'No Rex' model to the R1rho_analysis.py sample script.
        * A number of fixes for the script UI section of the dispersion chapter of the manual.  The NUMERIC_ONLY variable is now explained and the R1rho MODEL list has been changed to a set of reasonable models.
        * A GUI element for the insignificance level for the dispersion auto-analysis has been added.  This defaults to 1.0.  The user can input any number they wish.  Checks were added for non-numerical input.
        * Updated the insignificance argument docstring for the dispersion auto-analysis.
        * The dispersion analysis GUI element now uses the float GUI element for the insignificance level.  This makes sure that the user can only enter a number.
        * Created the Relax_disp.test_r2eff_read and Relax_disp.test_r2eff_read_spin system tests.  These check the operation of the currently non-existent relax_disp.r2eff_read and relax_disp.r2eff_read_spin user functions.
        * Modified the Relax_disp.test_r2eff_read system test.  A new disp_frq argument has been added for the relax_disp.r2eff_read user function.
        * Renamed specific_analyses.relax_disp.disp_data.exp_type() to set_exp_type().  This is to avoid classes with the 'exp_type' function arguments.
        * Small fix for the printout from specific_analyses.relax_disp.disp_data.set_exp_type().
        * Improved printout from the specific_analyses.relax_disp.disp_data.set_exp_type() function.
        * Improved printout for the relax_disp.cpmg_frq user function.
        * Improved printout for the relax_disp.spin_lock_field user function.
        * Implemented the relax_disp.r2eff_read user function.  Bot the frontend and backend have been implemented and are functional.
        * Created the Relax_disp.test_hansen_cpmg_data_auto_analysis_r2eff system test.  This is to test the full dispersion auto-analysis on Flemming Hansen's CPMG data using the original R2eff data rather than the derived peak heights.
        * Changes for the Relax_disp.test_hansen_cpmg_data_auto_analysis_r2eff system test.  The file paths have been changed.
        * Created files of R2eff values and errors for Flemming Hansen's CPMG data.
        * File path fixes for the script of the Relax_disp.test_hansen_cpmg_data_auto_analysis_r2eff system test.
        * The error analysis is now skipped in the dispersion auto-analysis if the 'R2eff' model is not given.  It is then assumed that R2eff/R1rho data has already been loaded into the base data pipe and hence the error analysis is not needed.  This avoids fatal errors.
        * The specific_analyses.relax_disp.disp_data.loop_time() function can now handle no relaxation times being set.
        * The relax_disp.r2eff_read user function now prints out all the data which has been read.  This feedback is useful for the user to know what has or has not been read into relax.
        * Fix for the dispersion auto-analysis if R2eff data already exists.  The data is no longer copied from the non-existent 'R2eff' data pipe.
        * Fixes for the dispersion specific overfit_deselect() method for when R2eff data is read.  This now no longer checks for intensity data but rather R2eff data, as intensity data will not be present if R2eff data is directly read rather than peak intensities.
        * Fixes for the Relax_disp.test_hansen_cpmg_data_auto_analysis system test.  The setup of the auto-analysis could be simplified as the base data pipe can now contain R2eff data.  The R2eff data in the 'R2eff' data pipe was no longer being read.
        * Some small fixes to allow the optimisation of dispersion models when no peak intensity data has been read.  This is for when R2eff data has been read instead.
        * The relax_disp.insignificance user function can now handle selected spins with no R2eff/R1rho data.
        * Fixes for the Monte Carlo simulations in the dispersion analysis when R2eff data has been read.  As peak intensity data has not been read, the relaxation time period will not have been set.  The _back_calc_r2eff() method can now handle this.
        * Improved the R2eff errors for Flemming Hansen's CPMG data.  The errors are now calculated using the data from all spins rather than a truncated subset.  The errors will therefore be much more accurate.
        * Fix for return_index_from_disp_point() for when R2eff/R1rho data is loaded rather than intensities.  This specific_analyses.relax_disp.disp_data.return_index_from_disp_point() function was always subtracting 1 from the dispersion point index to take the reference spectrum into account.  This however fails if R2eff/R1rho data is loaded instead.
        * Fixes for the Relax_disp.test_hansen_cpmg_data_auto_analysis* system tests.  The Relax_disp.test_hansen_cpmg_data_auto_analysis system test needed updating due to the more accurate R2eff errors.  The Relax_disp.test_hansen_cpmg_data_auto_analysis_r2eff system test also needed this change.  It also no longer has a spin system for residue 4.
        * Fixes for all of the Relax_disp system tests which use Flemming Hansen's CPMG data.  These are needed due to the improved error estimates in the data files.
        * Fix for a duplicated line typo in the Relax_disp.test_hansen_cpmgfit_input system test.
        * Fixed a typo in the user function name in the Relax_disp.test_r2eff_read_spin system test.
        * Fixes for the Relax_disp.test_r2eff_read_spin system test.
        * Implemented the relax_disp.r2eff_read_spin user function.  This allows R2eff/R1rho files for each spin to be read.
        * Fixed a docstring talking about RDC data in the dispersion analysis.
        * Fix for the Relax_disp.test_hansen_cpmg_data_auto_analysis_numeric system test for 32-bit Linux.  The 'NS CPMG 2-site expanded' model checks have been turned off again for residue 71 as these results are far to variable.
        * Another fix for the Relax_disp.test_hansen_cpmg_data_auto_analysis_numeric system test.  The selected model is no longer checked for residue 71.
        * Loosened the checks for a number of Relax_disp system tests to allow them to pass on 32-bit Linux.
        * Loosened a check for the Relax_disp.test_hansen_cpmg_data_to_ns_cpmg_2site_star system test for Mac OS X.
        * Loosened a check for the test_hansen_cpmg_data_to_ns_cpmg_2site_star system test for MS Windows.
        * Added some polish to the relax_disp.exp_type user function frontend.
        * Created the MODEL_LIST_CPMG_NUM dispersion list variable.  This is for defining in one place the list of models which require the number of CPMG blocks.
        * The dispersion optimisation code now checks for the relaxation time period being set for certain models.  This is for the models which require the number of CPMG blocks, calculated via the relaxation time and nu_CPMG.
        * The dispersion target function setup now uses the new MODEL_LIST_CPMG_NUM variable.
        * The dispersion specific check_exp_type() function now accepts the id argument to check individual IDs.
        * Redesigned the relax_disp.r2eff_read and relax_disp.r2eff_read_spin user functions.  These now no longer set the metadata (spectrometer frequency and experiment type) themselves.  Instead an experiment ID string must be supplied.  The spectrometer.frequency and relax_disp.exp_type user functions will therefore need to be called before these R2eff functions.
        * Fixes for the Relax_disp.test_hansen_cpmg_data_auto_analysis_r2eff system test.  This is for the changes in the relax_disp.r2eff_read user function.
        * Fixes and completion of the Relax_disp.test_r2eff_read and Relax_disp.test_r2eff_read_spin system tests.  These now handle the new user function design and now also check all of the global and spin data.
        * A number of fixes for the dispersion analysis for all the recent changes.
        * Better MMQ data support for the dispersion specific loop_cluster() function.  For the models using proton-heteronuclear multi-multiple quantum data, proton spin containers are now skipped as all the data will be analysed from the perspective of the heteronucleus.
        * Conversion of the format of the relaxation dispersion R2eff/R1rho data structures.  These are now lists of lists of lists of numpy arrays instead of pure numpy rank-4 arrays.  This only affects a number of related data structures in the dispersion target function class.  The main purpose is to prepare to have a different number of dispersion points per experiment, per spin, and per spectrometer frequency.
        * The return_cpmg_frqs() and return_spin_lock_nu1() dispersion functions now return lists of lists of arrays.  The dispersion data structures are now experiment and spectrometer frequency dependent.  Therefore the number of dispersion points can now be different for each.
        * The dispersion target function num_disp_points structure is now variable.  The number of points can now be different for each experiment type and each magnetic field strength.
        * Added a header comment to the grace2images.py script to explain its dependence on Grace.  This is thanks to feedback from Nikolai Skrynnikov.
        * Better organisation of the models by data type in the dispersion software comparison table in the manual.
        * Added Dmitry Korzhnev's cpmg_fit software to the dispersion chapter of the manual.  This is in the last section of that chapter and in the software comparison table.
        * Added the chemex software to the dispersion chapter of the user manual.
        * Updated the GLOVE details in the dispersion software comparison table in the manual.
        * Updates for the TODO section of the dispersion chapter of the user manual.  Some of the entries were rubbish.
        * Readded the accidentally deleted \clearpage command to keep the dispersion software table nicely formatted.
        * Added the scripting interface for cpmg_fit to the dispersion software comparison table in the manual.
        * Added constrained optimisation and Monte Carlo simulations to the dispersion software comparison table.  This is for the user manual.
        * Added a section on open source licencing to the dispersion software comparison table.  This is for the dispersion chapter of the user manual.
        * Updated the GUARDD details in the dispersion software comparison table of the manual.
        * Added a section about programming language to the dispersion software comparison table of the manual.
        * Added a page break for better formatting of the dispersion software comparison table of the manual.
        * Removed a now unneeded midrule from the dispersion software comparison table.
        * Editing and expansion of the dispersion software comparison table in the manual.  The optimisation algorithms are now listed, where known.  A number of entries and sections have also been rearranged.
        * More updates for the dispersion software comparison in the manual.
        * Updates for the grid search and GLOVE in the dispersion software comparison table in the manual.
        * More updates for the dispersion software comparison table in the manual.
        * Updated the dispersion software comparison table in the manual for GUARDD.  This is based on feedback from Ian Kleckner.
        * A bit more editing of the dispersion software comparison table of the manual.
        * Expanded the abbreviations of the user manual for many relaxation dispersion terms.
        * Update for NESSY in the dispersion software comparison table of the manual.
        * Added more R1rho model references to the bibliography file for the manual.  This includes the Trott and Palmer 2004 N-site and the Miloushev and Palmer 2005 2-site models.  The Trott and Palmer 2002 R1rho model reference has been expanded to include all details.
        * Added the TP04 and MP05 R1rho dispersion models to the manual.  These are not implemented in relax, or any of the software in the software comparison section, but are included for completeness.  This was pointed out by Art Palmer.
        * Added the Korzhnev et al., 2005 reference to the bibliography file for the manual.
        * Fixes for a number of page numbers in the bibtex file for the user manual.
        * Expanded the numeric dispersion models to include the linear and branched 3-site models in the manual.
        * Removed a typo from the dispersion model table.
        * Rearranged the sections of the dispersion chapter of the manual.
        * Improvements for the supported dispersion model table in the manual.  Footnotes have been added to indicate which models are not implemented yet.
        * Updated the TODO section of the dispersion chapter of the manual for the newly listed models.
        * Fix for the figure labelling in the dispersion chapter of the manual.
        * Small LaTeX layout changes to the dispersion chapter file.
        * Updated the dispersion software comparison table for the optimisation in GUARDD.  I have added the 'MATLAB interior-point black magic' algorithm as MATLAB is not kind enough to explain what algorithm it is really using.
        * The Arrhenius analysis is also performed by cpmg_fit.  This is for the dispersion software comparison table in the manual.
        * Added the TAP03 model to the dispersion chapter of the user manual.
        * Updated some ShereKhan language details in the dispersion software comparison table of the manual.
        * The dispersion GUI analysis now uses graphics.fetch_icon() for all icons.  The gui.paths module no longer exists.
        * Created the Relax_disp.test_tp02_data_to_mp05 system test.  This was copied from the Relax_disp.test_tp02_data_to_tp02 system test.  The r1rho_off_res_tp02.py system test script was modified to handle both tests by allowing the list of models to optimise to be set via the ds.models variable.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_test_suite
        * Added the 'MP05' model to the dispersion variables.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Adding_the_model_to_the_list
        * Added the 'MP05' model to the relax_disp.select_model user function frontend.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_front_end
        * Added support for the 'MP05' model to the relax_disp.select_model user function back end.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_back_end
        * Created the 'MP05' model target function.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_target_function
        * Added the 'MP05' R2eff calculating function to the relax library.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_library.  Just in case git-svn does not preserve the file copying history, the lib/dispersion/mp05.py file was copied from the tp02.py file.
        * Debugging of the 'MP05' dispersion model - optimisation is now setup correctly.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.html#Debugging
        * Fixes and improvements to the Relax_disp.test_tp02_data_to_mp05 system test.  The MP05 model values, which are almost the same as the TP02 model parameters, are now being checked.  The optimised parameters are now being printed out to aid in debugging.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.html#Debugging
        * Speed ups of the Relax_disp.test_tp02_data_to_tp02 and Relax_disp.test_tp02_data_to_mp05 system tests.  The optimisation precision and number of Monte Carlo simulations have both been dropped.
        * Added the 'MP05' model to the GUI model list.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_GUI.
        * Added the 'MP05' model to the dispersion auto-analysis.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_auto-analysis.
        * Added the 'MP05' model to the relax user manual.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_manual.  The 'MP05' model was already partly in the manual, however it was listed as unimplemented.  All of the tables and the dispersion chapter text has been updated for the model.
        * Modified the R1rho_analysis.py sample script to use the 'MP05' model.  This is the Miloushev and Palmer 2005 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_sample_scripts
        * The limitations of the 'TP03' dispersion model are now listed in the user manual.
        * The 'MP05' and 'NS R1rho 2-site' are now nested in the dispersion auto-analysis.  As the 'MP05' model is valid across all times scales and does not require skewed populations, its optimised parameters can be used as the starting point of optimisation of the 'NS R1rho 2-site' numeric model.  This results in huge speed ups of the numeric model as previously a grid search was being performed.
        * Removed all remnants of the MQ R1rho data type.  This data type does not exist and was mostly removed, but some small bits remained.
        * Created the Relax_disp.test_tp02_data_to_tap03 system test.  This is the Trott et al, 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_test_suite This was copied from the Relax_disp.test_tp02_data_to_mp05 system test.
        * Added the 'TAP03' model to the dispersion variables.  This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#Adding_the_model_to_the_list.
        * Added the 'TAP03' model to the relax_disp.select_model user function frontend.  This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_front_end.
        * Added support for the 'TAP03' model to the relax_disp.select_model user function back end.  This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_disp.select_model_user_function_back_end.
        * Created the 'TAP03' model target function.  This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_target_function.
        * Added the 'TAP03' R2eff calculating function to the relax library.  This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_library.
        * Debugging of the 'TAP03' dispersion model - optimisation is now setup correctly.  This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.html#Debugging.
        * Debugging of the 'TAP03' dispersion model.  Removed a Unicode character from the lib.dispersion.tap03 module docstring to allow it to be used in Python 2.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.html#Debugging.
        * The lib.dispersion.tap03 module can now handle negative gamma values.  This avoids fatal errors during optimisation.
        * Many fixes for the lib.dispersion.tap03 module to match the original equations.  The 'TAP03' model solution is now similar to those of 'TP02' and 'MP05'.
        * Updated the Relax_disp.test_tp02_data_to_tap03 system test numbers to match the optimised values.  These were so close to the MP05 model values that the test was passing anyway.
        * Added the 'TAP03' model to the GUI model list.  This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_GUI.
        * Added the 'TAP03' model to the dispersion auto-analysis.  This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_auto-analysis.
        * Added the 'TAP03' model to the relax user manual.  This is the Trott, Abergel and Palmer 2003 R1rho analytic model for 2-site off-resonance exchange.  This follows the tutorial for adding relaxation dispersion models at http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax#The_relax_manual.  The 'TAP03' model was already partly in the manual, however it was listed as unimplemented.  All of the tables and the dispersion chapter text has been updated for the model.
        * Added the 'TAP03' and 'MP05' models to the abbreviations in the user manual.
        * Improvements to all of the R1rho model descriptions in the dispersion chapter of the manual.
        * Added a placeholder for the relaxation dispersion citation to the citation chapter of the manual.  The bibtex entry for this will need to be updated later once the citation is published.
        * Added support for 1H SQ CPMG data for the MMQ-type dispersion models.  The key is to skip the protons in the spin cluster loops and to instead find the proton spin containers attached to the heteronuclei of the spins of the cluster.  The EXP_TYPE_PROTON_SQ_CPMG and EXP_TYPE_PROTON_MQ_CPMG experiment type variables have been created to aid this.  The MODEL_LIST_MMQ list variable has also been created to more consistently identify the MMQ-type dispersion models.  The has_disp_data() function has been created to simplify the finding of dispersion data for a given cluster, experiment type, spectrometer frequency and dispersion point.  The has_proton_sq_cpmg() and has_proton_mq_cpmg() are used to determine if there is proton dispersion data for the given heteronucleus.  The loop_exp() function has been modified to yield the proton SQ and MQ data if present.  Similarly the num_exp_types() and return_index_from_exp_type() functions exhibit different behaviour if this data is present.  The return_r2eff_arrays() function now assembles all of the proton data on top of the heteronuclear data by fetching the protons attached to the heteronuclei and aliasing the correct spin for the given experiment type.
        * Updated the relaxation dispersion target functions.  The input data structures have changed type.
        * Implemented the 'MMQ 2-site' CPMG model equations from the Korzhnev et al., 2005 reference.  The paper reference is "Dmitry M. Korzhnev, Philipp Neudecker, Anthony Mittermaier, Vladislav Yu. Orekhov, and Lewis E. Kay (2005).  Multiple-site exchange in proteins studied with a suite of six NMR relaxation dispersion experiments: An application to the folding of a Fyn SH3 domain mutant.  J. Am. Chem. Soc., 127, 15602-15611.  (doi:  http://dx.doi.org/10.1021/ja054550e)".  The original code from Mathilde Lescanne and Dominique Marion has only slightly been modified for this change as the MQ data treatment in the Korzhnev et al., 2004 reference is the same as in the 2005 reference, but using a different notation.  This has been renamed to r2eff_mmq_2site_mq().  The new r2eff_mmq_2site_sq_dq_zq() function has been added to the lib.dispersion.mmq_2site module to allows the SQ, DQ, and ZQ R2eff data to be calculated.  This function follows the notation of the 2005 paper.  The populate_matrix() function has been modified to only accept one combined chemical shift difference value.  It can now also accept different values for R20A and R20B, though the mmq_2site module defaults to R20A=R20B.
        * The r2eff_mmq_*() functions of lib.dispersion.mmq_2site now accept different R20A and R20B arguments.  These are set to the same thing within the dispersion target function.
        * Converted the spin specific 'r2', 'r2a', and 'r2b' dispersion parameters from lists to dictionaries.  The new parameter keys are based on the experiment type and the spectrometer frequency.  These keys are supported by the generate_r20_key() and decompose_r20_key() pair of functions in the specific_analyses.relax_disp.disp_data module.  This enables support for different R20 parameters for each experiment type - a key piece of infrastructure for the MMQ models.  The relax_disp.select_model user function backend was modified so the parameter list only contains one instance for each of the 'r2', 'r2a', or 'r2b' strings.  The specific_analyses.relax_disp.parameters.loop_parameters() function was modified so that the R20key rather than frequency index is returned for the R20 parameters.  Many other code changes were required.
        * The R20 values are now correctly handled in the dispersion target function for MMQ-type data.
        * Simplified the 'MMQ 2-site' dispersion model target function.  The r2eff_mmq_2site_sq_dq_zq() and r2eff_mmq_2site_mq() functions from lib.dispersion.mmq_2site are now aliased by the experiment_type_setup() target function method.  Both functions now have matching arguments.
        * Change of the base relaxation dispersion experiment types.  The base CPMG-type experiment has been changed from "CPMG" to "SQ CPMG".  This is for better combined proton-heteronuclear SQ, ZQ, DQ, and MQ (MMQ) data support.  The relax_disp.exp_type user function now also as the proton SQ and MQ CPMG-types available to select from rather than the previous behaviour of relax automatically determining the type from the spin type.  All of the CPMG experiment type variables in specific_analyses.relax_disp.variables have been renamed for better ordering.  Many changes were therefore required.
        * Fix for the specific_analyses.relax_disp.disp_data.num_exp_types() function.  This needed updating after the change in the relaxation dispersion experiment type variables.
        * Different relaxation time periods for each experiment is now taken into account in the dispersion code.  Previously only the first relaxation time period was being used.  This was fine for single data type models, but was preventing the MMQ-type models from working.  Now the return_r2eff_data() function of the specific_analyses.relax_disp.disp_data module assembles and returns the relax_times data structure which has two dimensions - the experiment type and the magnetic field strength.
        * Added a relax script to optimise just the 15N SQ CPMG data from Korzhnev et al., 2005.  The corresponding log file has also been added to the repository.
        * Created the Relax_disp.test_korzhnev_2005_15N_sq_data system test.  This is used to check the optimisation of the 15N SQ CPMG data using the 'MMQ 2-site' model.
        * Fixes for the dispersion optimisation Disp_result_command.run() method.  The dispersion point loop is fixed over all dispersion points, but the 'missing' data structure has a variable length.
        * Big redesign of the dispersion point returning and loop_*() functions.  These are the functions in the specific_analyses.relax_disp.disp_data module.  The return_cpmg_frqs() and return_spin_lock_nu1() functions now no longer take the spins and spin_ids arguments.  Instead they determine if a dispersion point exists for the given experiment and spectrometer frequency using the intensity keys and data in the base of the data pipe.  The specific_analyses.relax_disp.disp_data.loop_*() functions now accept the return_indices argument which if True will cause all of the relevant experiment type, spectrometer frequency, dispersion point, and relaxation time indices to be returned.  The behaviour of the loop_point() method is now different.  Instead of looping over all possible dispersion points, it only loops over those points present for the given experiment and spectrometer frequency.  This change allows for many simplifications and latent bug fixes in the dispersion analysis.
        * Added cmpg_fit input and results files for the 15N SQ CPMG data from Korzhnev et al., 2005.
        * Added cmpg_fit input and results files for all single CPMG data combinations from Korzhnev et al., 2005.
        * Updated the cpmg_fit results for the Korzhnev et al., 2005 single data sets.  The starting point for optimisation is now the solution for using all data together.  This allows a much better solution to be found for each script.
        * Created 5 more system tests for checking the optimisation of single sets of Korzhnev et al., 2005 data.  These are Relax_disp.test_korzhnev_2005_15n_dq_data, Relax_disp.test_korzhnev_2005_15n_mq_data, Relax_disp.test_korzhnev_2005_15n_zq_data, Relax_disp.test_korzhnev_2005_1h_mq_data, and Relax_disp.test_korzhnev_2005_1h_sq_data.  These should individually test out all parts of the 'MMQ 2-site' dispersion model.
        * The cpmg_fit script for the Korzhnev et al., 2005 15N ZQ CPMG data now starts at the relax solution.  This is to try to find better solutions for dw and dwH, thought it was not so successful.
        * Updated the Relax_disp.test_korzhnev_2005_15n_zq_data system test.  It now starts at the relax solution and the test passes as it seems to reasonably match the cpmg_fit results.
        * Reintroduced the F vector into r2eff_mmq_2site_mq() to calculate the magnetisation.
        * Added the cpmg_fit results for optimisation all of the Korzhnev et al., 2005 CPMG data.  This is for the 2-site model.  It includes all proton-nitrogen SQ, ZQ, DQ, and MQ data.
        * Updated the cpmg_fit results for all Korzhnev et al., 2005 data.
        * Shifted the relax results for the 15N SQ Korzhnev 2005 CPMG data to its own directory.  The relax save state and grace curve have been added to the repository as well.
        * Created a Grace plot of the failed cpmg_fit results.  This is for the Korzhnev et al., 2005 data, using all data sets.
        * Fixes for the cpmg_fit results for all of the data from Korzhnev et al., 2005.  The dwH value must start negative, otherwise optimisation will fail to find the correct minimum.
        * Created a Grace graph for the 1H SQ data fitting of cpmg_fit.
        * The dispersion specific overfit_deselect() method now handles the MMQ-type models better.
        * The 'MMQ 2-site' dispersion model can now be optimised if no heteronuclear R2eff data is loaded.
        * Many more fixes for the MMQ-type dispersion models for the proton spin data.
        * Added many new relax results for the CPMG data form Korzhnev et al., 2005.
        * The R2eff data key has been changed in the dispersion analysis.  The experiment type has been added to the key so that R2eff data is not mixed up when data from multiple experiments is present.
        * Updated the synthetic 'TP02' model data for the recent changes.
        * Fix for the dispersion base_data_loop() method for deselected spins.  A recent change broke this function when spins were deselected.
        * Updated the truncated CPMG data set from Flemming Hansen to include residue :4.  This is deselected in the test suite, but allows the comparison in the shared_data directory to use all four spins (:4, :70, :71).
        * Changed the current data pipe in the relax saved states for Flemming Hansen's truncated CPMG data.
        * Another change of the base relax files of the truncated CPMG data.
        * Bug fix for the relax_disp.cpmgfit_input user function.  The nu_CPMG values need to be doubled and then divided by 1e3 to obtain the 1/tau_CPMG values in ms.
        * Fix for the relax_disp.sherekhan_input user function for the recent changes.
        * Updated all of the results for the truncated CPMG data from Flemming Hansen in the test suite.  The results are now different as the errors are now much more precise as they come from all spin systems rather than just the truncated set of :4, :70, and :71.
        * Bug fix for the Ishima and Torchia 1999 dispersion model.  Their value of omega_1eff is defined in terms of nu_CPMG, hence it is missing the radian unit.  This is clearly a mistake, but is probably compensated by their stated rather than derived definitions.
        * Updated all of the relax results for the IT99 model fix.
        * Added the new relax IT99 model results to the software_comparison file.  This is for the truncated CPMG data from Flemming Hansen.
        * Fix for the LM63 dispersion model equation in the manual.
        * The CR72 dispersion model descriptions now emphasise the fact that it is not accurate on all time scales.  This is for the dispersion chapter of the user manual.
        * Modified the relax_disp.select_model user function CR72 model descriptions.  Instead of saying all time scales, the 'CR72', 'CR72 full', and 'MQ CR72' model descriptions instead now say most time scales.
        * Minor equation improvement in the dispersion chapter of the manual.
        * Fix for the relax_disp.plot_disp_curves user function in the GUI.  The directory argument was incorrectly set to the 'dir' type rather than 'dir sel' type so it was not shown in the GUI.
        * Created the relax_disp.write_disp_curves user function.  This is based on feedback from Nikolai Skrynnikov.  The user function will generate one file per spin system and dump all of the R2eff values (measured, back calculated, and errors) into the file.
        * The relax_disp.write_disp_curves user function is now called from the dispersion auto-analysis.
        * Another bug fix for the IT99 model.  This was pointed out by Nikolai Skrynnikov that the omega_1eff definition is incorrect and instead it should be omega_1eff = 4 * sqrt(3) * nu_CPMG.
        * Updated the Relax_disp.test_hansen_cpmg_data_to_it99 system test for the IT99 model fixes.
        * Updated the relax results for the truncated CPMG data from Flemming Hansen.  This is needed as the IT99 model has been fixed and the new relax_disp.write_disp_curves user function introduced.
        * Fix for the relax_disp.write_disp_data user function.  The spectrometer frequency in the output files is now in MHz.
        * A small output formatting change for the relax_disp.write_disp_curves user function.
        * The relax_disp.write_disp_curves user function is now more robust for when data is missing.
        * Fix for the setup of the Relax_disp.test_korzhnev_2005_1h_mq_data system test.
        * Fixes for the Relax_disp.test_hansen_cpmgfit_input system test.  These are needed as the relax_disp.cpmgfit_input user function has been fixed resulting in different files being produced.
        * Bug fix for the relaxation dispersion model selection.  Deselected spins in the current pipe were being skipped, so for model selection between different data pipes that results in spins not being used when they should be.
        * Bug fix for the dispersion specific model_information() method.  This can now handle deselected spins with no data.
        * Bug fixes for the model_loop() method no longer skipping deselected spins.  This is needed for model selection when the spins from all data pipes are deselected.
        * One last fix for the dispersion analysis for the changes of the model_loop() method.
        * Updated the relax script for optimising Flemming Hansen's CPMG data.
        * Better support for the MMQ-type data dispersion models for the end of the optimisation.  The back calculated R2eff values are now handled correctly for the attached proton in the spin system.
        * Updated the Relax_disp.test_korzhnev_2005_15n_dq_data system test so it passes.  The optimised values are very similar to that from cpmg_fit, so the code must be functioning correctly.
        * Improvement for the file names in the relax_disp.plot_disp_curves user function.  The '_' character is now used between the experiment name and the rest of the file name.
        * Bug fix for the specific_analyses.relax_disp.disp_data.find_intensity_keys() function.  This function was not handling multiple experiment types correctly.
        * Created the Relax_disp.test_korzhnev_2005_all_data system test for checking the 'MMQ 2-site' model.  This checks against all six data types, 1H SQ, 15N SQ, DQ, ZQ, 1H MQ, and 15N MQ.  This is currently set to the values found by cpmg_fit.  As this is the true solution, relax should find similar parameter values.
        * Created a Grace plot of the 15N MQ CPMG data fitting from cpmg_fit.
        * Bug fix for the multiple quantum relaxation dispersion models.  These require both the heteronuclear and proton chemical shift differences.  But the proton difference was being scaled by the heteronuclear Larmor frequency and not the proton frequency.
        * The relaxation dispersion calculate user function now stores the back calculated R2eff values.  A number of changes were required for this.  The code from the end of the Disp_result_command.run() method was converted to the function specific_analyses.relax_disp.disp_data.pack_back_calc_r2eff().  This allows the back calculation R2eff unpacking code to be shared.  The new has_proton_mmq_cpmg() function has also been created to simplify the code.
        * Bug fix for the dispersion calculate user function.
        * Created a script to compare the cpmg_fit and relax solutions for the 'MMQ 2-site' dispersion model.
        * Clean ups and speed ups of the 1H MMQ flag calls.
        * Large improvements to the relax_disp.plot_disp_curves user function including MMQ model support.  This user function now handles multiple dispersion data sets better by placing each into a new graph.  All graphs have also been improved by matching the colours of the sets for each field strength and using different symbols and line styles to emphasize the data.
        * Fixes for the relax_disp.plot_exp_curves user function for the lib.software.grace changes.
        * The relax_disp.plot_disp_curves now shows the experiment type as part of the Y-axis label.  This is to allow for easy identification of the experiment when more than one is present.
        * Bug fix for the 'MMQ 2-site' dispersion model target function.  The relaxation time was being taken as that of the first experiment for all experiments.  This is a relic from the code being copied from a single experiment type model.
        * Converted the 'MQ CR72' dispersion model to handle MMQ data.  This model can now handle proton-heteronuclear SQ, ZQ, DQ, and MQ CPMG-type data.  Some debugging might still be required.
        * Fix for the 'MQ CR72' model for MQ-type data.  The check to prevent acos of a number less than 1 has been changed to switch the sign rather than to set the back calculated R2eff to 1e99.
        * Another bug fix for the 'MQ CR72' dispersion model.  The nu_CPMG value rather than the relaxation time was being used to calculate the R2eff values as the division by 'n' was missing.
        * The relax_disp.plot_disp_curves user function can now handle values of NaN.  These are simply replaced by 0.0 to allow Grace to open the file.
        * Fixes for the 'MQ CR72' dispersion model target function.
        * Removed a latent bug in the 'MMQ 2-site' dispersion model.  This was not being seen but might have caused problems in the future.
        * Fix for the 'MQ CR72' dispersion model target function.  The correct R20 values are now extracted from the parameter vector.
        * Improvements for the 'CR72' and 'MQ CR72' dispersion model R2eff calculating functions.  The numpy.arccosh() function can handle all input values when complex, therefore the checks for the real part being above 1 are not necessary.
        * General improvement for the optimisation of many target functions.  For those models which use the tau_CPMG value, this is now recalculated.  This means that if a user inputs truncated nu_CPMG values, these are corrected when calculating tau_CPMG so that full precision values will be used for the optimisation.
        * Changed the sign of the delta_omega frequency for the ZQ data in the 'CR72' and 'MQ CR72' models.
        * Last fix for the 'MQ CR72' dispersion model.  The wrong value was being subtracted from the first eigenvalue - the value of log(Q)/relax_T should not be divided by the number of CPMG blocks.
        * Simplified the first 'MQ CR72' dispersion model formula in the manual.
        * Created a relax script to compare the 'MQ CR72' dispersion model results to cpmg_fit.  The cpmg_fit solution is used as the input parameters for relax, and then a calc user function call is used to back calculate the R2eff values.  These values are then plotted to show the perfect match.
        * Bug fixes for the 'MMQ 2-site' dispersion model.  The matrix power factor must be found with the Python math.floor() function and not int() as the later will sometimes round up.
        * Updated all of the relax vs. cpmg_fit comparison files in the shared data directory.  These now show the perfect match between the programs.  The cpmg_fit source code was modified to improve the accuracy of the gyromagnetic ratio values.
        * Updated the cpmg_fit results for the CPMG data of Korzhnev et al., 2005.  This is using a modified binary wherein the gyromagnetic ratio and optimisation tolerances and maximum number of iterations are far more accurate (to the same level as relax).  The cpmg_fit output has also been made more accurate by writing out the values to much higher precision.
        * Fixes for the relaxation dispersion system tests for the changed behaviour of the 'CR72' model.  The optimisation is slightly different as values are now always passed into the numpy.arccosh() function.
        * Eliminated the MODEL_LIST_CPMG_NUM variable.  This was far too specific and its misuse caused a bug in the target function of a number of dispersion models.
        * Fixes for a number of dispersion system tests due to the higher accuracy of the tau_CPMG values.  This is required as the tau_CPMG values have been corrected to eliminate user input truncation artifacts.
        * The Relax_disp.test_korzhnev_2005_all_data system test no longer dumps files in the current directory.
        * Updated all of the cpmg_fit results to use the numeric 2-site CPMG model.  This also uses the modified cpmg_fit binary with higher accuracy.
        * Updated the Relax_disp.test_sprangers_data_to_mq_cr72 system test to pass.  The 'MQ CR72' model is now much more accurate due to a number of recent bug fixes.
        * Fixes for all of the Relax_disp.test_korzhnev_2005_*_data system tests.  These now start optimising at the solution found by cpmg_fit.  All tests now pass.
        * Fix for the legends in the Grace graphs produced by the relax_disp.plot_disp_curves user function.
        * The grid search for the MMQ-type models now looks for negative chemical shift differences.
        * Converted the dispersion api method _back_calc_r2eff() into a function of the optimisation module.
        * Updated the spin-lock field strength data structures to be experiment and field specific.  This allows different spin-locks to be used as different field strengths, or different experiments.  It brings the structures in line with those for CPMG-type experiments.
        * Updates for the dispersion auto-analysis system tests using Flemming Hansen's data.  The grid search increments have been increased by one to make sure the solution is always found.
        * Increased the range of chemical shift differences in the grid search for the dispersion models.  The range was too narrow.
        * Fix for the Relax_disp.test_hansen_cpmg_data_auto_analysis system test.  The kex value check needed to be scaled back.
        * The relax_disp.plot_disp_curves user function now produces interpolated dispersion curves.  For this the new 'num_points' and 'extend' arguments have been added to the user function to give the user better control of this plotting.  The interpolated curve is disabled from the numeric CPMG models as these do not support interpolation, and the 'R2eff' model as interpolation is not needed.  To support this, the specific_analyses.relax_disp.optimisation.back_calc_r2eff() function has been extended to support the CPMG frequencies or spin-lock field strengths been supplied instead of retrieved.  This allows a set of custom dispersion points to be used in the back calculation.  The dispersion target function setup was modified to prevent the recalculation of tau_CPMG values when asked, as interpolation is not compatible with this.
        * The relax_disp.plot_disp_curves user function now places the X-axis at zero.  This is for better visualisation of the residuals.
        * Interpolated curves are now produced for the numeric CPMG-type models.  This if for the relax_disp.plot_disp_curves user function.  The resolution of these are limited to the frequency of a single CPMG block in the relaxation time period.  Therefore the plots are produced slightly differently.  To enable this functionality, the new count_exp() and return_relax_times() functions have been added to the specific_analyses.relax_disp.disp_data module.
        * Improved the text for the relax_disp.plot_disp_curves user function.
        * Fix for the interpolation for the numeric CPMG-type models in relax_disp.plot_disp_curves.
        * Updated the relax results files for the CPMG data from Korzhnev et al., 2005.
        * Improvements to the data-type labelling in the dispersion chapter of the user manual.
        * The dispersion model GUI window is now set to a reasonable size for most screens.  The scrolled panel now allows all contents to be shown while having the window smaller than its contents.  The height of 750 pixels should be visible on the majority of computer monitors.  According to Google Analytics, ~13% of visits to http://www.nmr-relax.com have screen resolutions of 1366x768, therefore the dispersion model list window should now not be bigger than their screens.
        * Merged the 'MQ CR72' dispersion model into the MMQ data type sections in the tables of the manual.
        * Implemented model elimination for the relaxation dispersion analysis.  This currently uses the pA limits of 0.501 < pA < 0.999 to determine if a model has failed.  To implement this, the dispersion API methods deselect(), eliminate(), get_param_names() and get_param_values() were written.  These were copied from the model-free analysis and modified as needed.
        * Model elimination is now activated in the dispersion auto-analysis.
        * The relaxation dispersion target function class can now handle cpmg_frqs arguments of None.  This is useful for R1rho models.
        * Bug fix for the recently added dispersion API eliminate method.  This was accidentally always eliminating the model.
        * Created a new section in the dispersion chapter of the manual covering optimisation.  This describes the auto-analysis, the chi-squared function, the grid search values, how optimisation is implemented, the linear constraints used, the diagonal scaling, model elimination, and the use of OpenMPI.  It absorbs the clustering section. 
        * Improvements for the dispersion API eliminate() method.
        * Added text about the relax_disp.insignificance user function to the dispersion chapter of the manual.
        * Updates for the 'MMQ 2-site' model equations in the manual.
        * Added the tex > 1.0 model elimination rule for the dispersion analysis.
        * Updated the description of the dispersion auto-analysis in the manual.
        * Added a MC simulation elimination section to the dispersion chapter of the manual.
        * Fix for the new analysis GUI wizard - two model-free analysis buttons were present.  This is due to an imperfect merge of the relax_disp branch back to trunk.
        * Fixes for the lib.software.grace for an imperfect merger of the relax_disp branch.
        * Fix for the Noe.test_noe_analysis system test.  The old Grace file was turning the legend first off and then on, but now this is fixed.
        * Fixes for the Relax_disp.test_tp02_data_to_tp02 GUI test.  This should have been fixed in the relax_disp branch.
        * Fix for the Wiz_window.setup_page() method.  The user function SetValue() methods are no longer called but instead the Uf_page.SetValue() method is used to set up user function arguments.  This is important as this later method can properly handle the free file format arguments and other special arguments whereas the former cannot.
        * Attempts at fixing and improving the Relax_disp.test_hansen_trunc_data GUI test.  These changes have uncovered a spin ID updating problem in the relax data store after calling the residue.delete user function.
        * Fix for two system tests to prevent relax save files from being dumped in the installation directory.  This would have been fatal for the tests suite on systems with relax installed as root.
        * Fix for the GUI tests for a wxPython 2.9 ListCtrl.HitTest() bug.  This only affects the relax test suite.  The suite should now pass on all systems.
        * Shifted the dispersion chapter of the user manual to its correct position.  Somehow during the relax_disp branch merger, this chapter was shifted into the "Advanced Topics" partition of the manual.
        * API documentation fix for test_suite.system_tests.relax_disp.Relax_disp.setup_korzhnev_2005_data().
        * Limited the optimisation time in the N_state_model.test_populations system test.  This test can take a huge amount of time on Mac OS X and MS Windows (~6 seconds on Linux, ~360 seconds on Mac OS X, and ~120 seconds on MS Windows, all on similar hardware).  Now the minimise user function max_iter argument is set to 2000 to speed the test up.
        * Increased the speed of the N_state_model.test_populations system test again.  The maximum number of iterations for the minimise user function is now set to 500.
        * Fix for the N_state_model.test_populations system test on Mac OS X.  The optimisation on Macs is not as precise as on Linux, so the test was loosened.
        * Fix for the Relax_disp.test_m61_exp_data_to_m61 system test on 32-bit Mac OS X.  The optimisation precision was not great enough to find the minimum, so the grid search increments have been increased from 3 to 4.
        * Loosened all of the Relax_disp.test_korzhnev_2005_*_data system tests to pass on Mac OS X.  This should hopefully fix the tests for MS Windows as well.
        * More loosening of the Relax_disp.test_korzhnev_2005_*_data system tests to pass on Mac OS X.  These problems were identified on a different test machine.
        * Loosened all checks of the N_state_model.test_populations system test.  This is needed for the woeful optimisation capabilities of Mac OS X (and partly MS Windows as well).
        * Avoided some wxPython 2.9.4.1 in the Relax_disp GUI tests.  wxPython is quite buggy, so certain checks and tests cannot be performed.
        * Fix for the specific_analyses.relax_disp.optimisation.back_calc_r2eff() function.  The R2eff error data structure when the cpmg_frqs or spin_lock_nu1 argument is supplied was all zeros, whereas it should all be ones.  This was causing many divide by zero numpy warnings to appear on certain operating systems (Mac OS X).
        * The relax system test base tearDown() method should now be fail proof.  Most code is now warped in a 'try: except: pass' block to catch all failures.
        * Improvements in the test_suite.clean_up.deletion() function.  It is now more fail safe on Python 3 by completely avoiding the WindowsError checking.


    Bugfixes:
        * Bug fixes for a number of broken Oxygen icon lookups in the GUI.
        * Bug fixes for the molecule.delete, residue.delete and spin.delete user functions.  The molecule, residue, and spin metadata in the relax data store was not being updated correctly after these user function calls so that any subsequent operations on this data was failing.  This metadata problem was not noticed before as it disappears if the state is saved and reloaded into relax after a restart.



Version 3.0.2
(26 November 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/3.0.2

    Features:
        * Much better pseudo-atom support, including not requiring tetrahedral geometry.
        * The value.write user function can now create files with non-numeric data, such as the models for each spin.
        * Improvements to the 2D Grace plotting from the grace.write user function including full support for multiple graphs and the setting of the axes to the zero point.


    Changes:
        * Updated the Release Checklist document rsync instructions to allow resumed uploads.  This is needed if the internet connection has been cut, as uploading can take a long time.
        * The test_suite.clean_up.deletion() function can now handle the case of missing files and directories.  This problem was occurring in the relax_disp branch for some of the system tests.
        * Created the is_int() and is_num() functions for the lib.check_types module.
        * The value.write user function can now properly handle non-numeric data types.  This allows the spin specific model name to be written to file, or any other string defined in the specific analysis PARAMS data object.
        * The multi-processor section of the manual is now labelled in the correct position.
        * Created a special GUI analysis element for floating point numbers.  This allows for user input of floating point numbers into one of the GUI analysis tabs.  If the input is not a number, the original value will be restored.
        * Created the new pipe_control.spectrum.add_spectrum_id() function.  This is used to handle the creation of spectrum ID strings in the data store.  This way new spectrum IDs can be created from different parts of relax in a controlled way.
        * Created the pipe_control.spectrometer.check_frequency() function to standardise this check.
        * Created the pipe_control.spectrometer.get_frequency() function for returning the frequency for a given ID.
        * The pipe_control.spectrum.add_spectrum_id() function now returns silently if the ID already exists.
        * Improvements to the pymol.view and molmol.view user functions for finding the PDB files.  Now the possibility that this is being run from a results subdirectory is taken into consideration.  If the file cannot be found, the os.pardir parent directory is added to the start of the relative path and the file checked for.
        * The rdc.read user function will now skip all lines of the RDC file starting with '#'.  To include molecule identifiers at the start of the line will now require quotation marks.
        * Shifted the RDC and PCS assembly methods from the main class to the data module for the N-state analysis.
        * Created the pipe_control.mol_res_spin.is_pseudoatom() function to simplify pseudo-atom handling.
        * Created the pipe_control.mol_res_spin.pseudoatom_loop() function.  This is used to loop over the spin containers corresponding to a given pseudo-atom.
        * Added a PDB file and RDC values (and absolute J+D and J) for propylene carbonate.  This will be used for testing of pseudo-atoms in the N-state model analysis.
        * Renamed the propylene carbonate files to the correct name of pyrotartaric anhydride.
        * Created two new system tests based on the new pyrotarctic anhydride long range (1J, 2J & 3J) RDC data.  The first (N_state_model.test_pyrotartaric_anhydride_rdcs) optimises an alignment tensor using long range signed RDC data.  The second (N_state_model.test_pyrotartaric_anhydride_absT) optimises an alignment tensor using long range absolute T (J+D) data.  Both test long range data together with methyl group pseudo-atom data.
        * Added all of the pyrotartaric anhydride RDC generation scripts and files.  This is simply for reference and reproducibility.
        * Modifications for the pyrotartaric anhydride system test script.  The grid search now is much quicker, and the RDC correlation plots are now sent to DEVNULL.
        * Added the return_id argument to the pipe_control.mol_res_spin.pseudoatom_loop() function.  This will then yield both the spin container and spin ID string.  This mimics the spin_loop()function.
        * Added proper pseudo-atom support for the RDCs in the N-state model analysis.  This involves a number of changes.  The pseudo-atom specific functions ave_rdc_tensor_pseudoatom() and ave_rdc_tensor_pseudoatom_dDij_dAmn() have been added to the lib.alignment.rdc module.  These simply average the values from the equivalent non-pseudo-atom functions.  The return_rdc_data()function in the specific_analyses.n_state_model.data module has been modified to assemble the RDC constants and unit vectors for all members of the pseudo-atom and add these to the returned structures, as well as a new list of flags specifying if the interatom pair contains pseudo-atoms.  The N-state model target function and gradient have been updated to send the pseudo-atom data to the new lib.alignment.rdc module functions.
        * J couplings for the N-state analysis are now properly handled for pseudo-atoms.  The measured J couplings for the members of the pseudo-atom should not be used, but rather that of the pseudo-atom spin itself (as the former does not exist).
        * Eliminated the old pseudo-atom handling in the N-state model specific return_rdc_data() function.  This was multiplying the RDCs by -3 to handle the tetrahedral geometry of the 1J methyl RDCs.  However this approach is not valid for non-methyl pseudo-atoms or for 2J, 3J, etc. data.
        * A RelaxError is now raised for the N-state model optimisation with gradients when T = J+D data is used.  The gradients for this data type are not implemented yet, so it is better to prevent the user from using this.
        * The N_state_model.test_pyrotartaric_anhydride_absT system test now uses simplex optimisation to pass.  The Newton algorithm cannot be used as the gradients for T = J+D type data have not been implemented.
        * An RDC error of 0.0 will now deselect the corresponding interatomic data container.  This can be used for simpler pseudo-atom handling.
        * Updated the menthol long range RDC data file to include pseudo-atom member distances.
        * Renamed the interatomic_loop() function 'selected' argument to 'skip_desel'.  This is to match the spin_loop() function arguments.
        * The interatom.unit_vectors user function now calculates the unit vectors for deselected containers.  This is useful for pseudo-atom handling where the interatomic containers to the pseudo-atom members have already been deselected.
        * Updated the value checking for the N_state_model.test_absolute_rdc_menthol system test.  The pseudo-atoms are now properly handled so the result is now much better.
        * The stereochemistry auto-analysis can now accept a file of interatomic distances.  This is for better pseudo-atom support.
        * The N-state model specific check_rdcs() function now properly handles pseudo-atoms.
        * The pipe_control.rdc.q_factors() function now properly handles pseudo-atoms.  If pseudo-atoms are present, then 2Da^2(4 + 3R)/5 normalised Q factor is skipped.
        * Created the N_state_model.test_pyrotartaric_anhydride_mix system test.  This is used to demonstrate a bug in the N-state analysis using mixed RDC and long range absolute J+D data.
        * Movement of N-state model specific code to the analysis neutral pipe_control package.  Many of the functions of the specific_analyses.n_state_model.data module relating to alignment tensors, RDC data and PCS data have been shifted in to the pipe_control package modules align_tensor, rdc, and pcs respectively.  This allows these functions to be made more general and allow the code to be shared with the frame order analysis or any future analysis using such data, and hence remove some code duplication.
        * Create two new warnings RelaxNucleusWarning and RelaxSpinTypeWarning to match the equivalent errors.
        * Added some RDC data checks to the N_state_model.test_pyrotartaric_anhydride_rdcs system test.  This is to demonstrate a problem with the data assembly function pipe_control.rdc.return_rdc_data().
        * Clean ups and improvements for the pipe_control.rdc.check_rdcs() function.  Pseudo-atoms are now handled much better and correctly in all cases.  And many RelaxErrors have been converted to RelaxWarnings followed by a 'return False' statement.
        * Created the pipe_control.rdc.setup_pseudoatom_rdcs() function.  This is used to make sure that the pseudo-atom interatomic systems (the containers from heternucleus to pseudo-atom and heteronucleus to pseudo-atom members) are properly set up.  It will deselect the interatomic containers if incorrectly set up or if they are not part of the main pair.
        * Added quotation marks around a number of spin IDs with molecule names in some RDC data files.  This is for the N-state model population model data used in the test suite.
        * The rdc.read and j_coupling.read user functions now ignore all lines starting with the # character.  This is to remove all comment lines silently.  Therefore if spin IDs are used which contain the molecule name, then they should be wrapped in quotation marks.
        * Updated a number of RDC test suite data files to have quotation marks around the spin IDs.  This is to allow the molecule identifier to be present while not being mistaken for a comment line.
        * Updated some of the RDC data files used in the frame order system tests.  The spin IDs are now in quotation marks as the molecule name is included.  This is to prevent the line being removed as a comment.
        * Changes to the setup_pseudoatom_rdcs() function and renamed it to setup_pseudoatom_rdc().  The interatomic loop is now within the function to make sure that all is completed before the containers are accessed.
        * Started to add better pseudo-atom support for the PCS.  The new pipe_control.pcs.setup_pseudoatom_pcs() function has been added to deselect the spins which are members of a pseudo-atom.  The return_pcs_data() function in the same module now calls this function and builds a list of pseudo-atom flags for use in the target function (though it is still unused).
        * Finally eliminated the gui.paths module, replacing it with graphics.fetch_icon() calls.  The GUI was using a mix of the old gui.paths module and the fetch_icon() function.
        * Created the pipe_control.sequence.return_attached_protons() function.  This is used to return a list of proton spin containers attached to the given spin.
        * Improved Grace graph scaling and arrangement when multiple graphs are present.  The lib.software.grace.write_xy_data() function now executes the 'autoscale' command for each graph and executes the 'arrange' to layout the graphs automatically.
        * The Grace plotting (via lib.software.grace) now fully supports the plotting of multiple graphs.
        * Improvements to the lib.software.grace module.  The set colours are now applied to all set objects.  And the axis label and tick sizes are now much smaller.
        * Created the --numpy-raise command line option.  When this is set, all numpy warnings will be converted to errors.  This is to aid in debugging to locate where the warning messages are coming from.  These appear as RelaxWarnings, but there is no indication as to where the problem is.
        * The lib.software.grace module now supports setting the X and Y axes at zero.
        * Modified the model list GUI window.  This can now be resized and it uses a scrolled panel to allow the contents of the window to be bigger than the window size.


    Bugfixes:
        * Fix for bug #21233 (https://gna.org/bugs/?21233) - the missing mpi4py multi-processor messages.  When multiple commands were being sent to one slave, the captured IO was being overwritten by each executed command.  Therefore the slave would only return the printouts from the last command.
        * Fix for a fatal bug in the rarely used structure.add_atom user function.  The position argument in the user function definitions was incorrectly defined causing the user function to be non-functional.  The 'float_object' argument type is now supported in the GUI.
        * Fix for the N-state model _target_fn_setup() method for when no PCS data is present.
        * Bug fix for the lib.structure.mass.centre_of_mass() function warning when the element is not known.  This warning was buggy and resulted tracebacks.



Version 3.0.1
(17 October 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/3.0.1

    Features:
        * Improved handling of peak lists.
        * Simplification of the user function GUI elements for those associated with the free file format.
        * Support for the reading of chemical shifts into the relax data store with the new  chemical_shift.read user function.
        * Improvements to the appearance of the GUI by using more unicode.
        * Redesign of the model list GUI element used in the model-free analysis.


    Changes:
        * The font size is no longer set for the latex2html compiled user manual.
        * A number of updates and improvements to the document explaining how to setup a Mac OS X framework.  This Framework Python setup is used to build the binary distribution files.
        * Updated the Mac Framework testing script to handled 4-way binaries (ppc74 included).
        * Better support for 4-way binaries in the Mac OS X Framework detection script.
        * Added support for the 'current ar archive random library' file type in the Mac OS X Framework testing script.
        * Added py2app to the Mac OS X Framework setup instructions.
        * Shifted code from pipe_control.spectrum to the new lib.spectrum.peak_list relax library module.  This follows from http://thread.gmane.org/gmane.science.nmr.relax.devel/3972/focus=4347.
        * Added a special script for locating all Python versions and printing out the installed modules.
        * Large change to the free file format GUI element for the user functions.  The GUI element used in the user function wizard windows has been modified to have both a 'default' form, which is the previous design, and a 'mini' form which is now used for the user functions.  This mini form only uses 1 row, rather than the default of 6 or 8.  It is a read only text element with a button that launches the free file format window.  The amount of space saved is huge.
        * Improved the text for the mini free file format GUI element.
        * Updated all of the user function GUI window sizes for the 'mini' free file format GUI element.  This allows much more text of the description to be displayed.
        * Updated the Mac Framework setup document to help with scipy compilation problems.
        * Improved the Python seeking and module version print out script for symlinks.  This should now be much more capable of finding all Python versions on a system.
        * Added support for the Mac OS X Modelfree4 binary results to the Palmer.* system tests.  The Mac OS X Modelfree 4.20 binary produces different results than the Linux binaries, mainly due to a compilation problem.  In the Linux binaries, the results are written out to 4 decimal places.  In the Mac binaries, the results are instead written out to 4 significant figures.  Therefore the number of decimal places are much less than the Linux results.
        * Syntax error fix for one of the unused scripts in the relax test suite shared data directories.  This problem was encountered by Jack Howarth <howarth att bromo dott med dott uc dott edu> and communicated in a private message.  The issue was found by fink.  This script is never used and will never be used again - it is only there for reference.
        * Modification of the spectrum.read_intensities user function front end.  The heteronuc and proton arguments have been eliminated.  Instead the new dim argument is used to associate the data with the spins of any dimension in the peak list.
        * Replaced the 'heteronuc' and 'proton' arguments of the spectrum.read_intensities user function backend with 'dim'.
        * Created the new lib.spectrum.objects module.  This will hold temporary data structures for representing peak lists and other spectral data.  The module currently contains the Peak_list class which is used to hold peak list data.
        * Started to shift the spectrum.read_intensities user function backend to use lib.spectrum.peak_list.
        * The pipe_control.spectrum.read_intensities() function now works with the Peak_list object.
        * The Peak_list object is now used by the lib.spectrum.peak_list.read_peak_list() function.
        * The lib.software.sparky.read_list_intensity() function now operates on the Peak_list object.
        * Changed the spectrum.read_intensities dim argument default to w2 and improved the long description.
        * Fix for the assignment handling in the lib.software.sparky.read_peak_list() function.  The first element is usually the indirect dimension or w2.
        * Fix for many of the Peak_list system tests for the user function argument changes.  The heteronuc and proton arguments have been replaced by the dim argument.
        * The lib.software.xeasy.read_list_intensity() function now operates on the Peak_list object.
        * The lib.software.nmrview.read_list_intensity() function now operates on the Peak_list object.
        * The lib.spectrum.peak_list.intensity_generic() function now operates on the Peak_list object.
        * Fixes for the pipe_control.spectrum.read() function.  An error was referencing a now non-existent variable and the docstring has been fixed.
        * The Peak_list object can now store peak intensity names.  This is for peak lists such as from NMRPipe seriersTab files where the peak list covers multiple spectra.
        * The NMRPipe seriesTab peak lists are now supported through the Peak_list object.
        * Unit test fixes for the spectrum.read_intensities user function argument changes.
        * Fixes for a few system tests for the spectrum.read_intensities user function argument changes.
        * Fixes for a few GUI tests for the spectrum.read_intensities user function argument changes.
        * Changes for the spectrum.read_intensities user function dim argument.  The default is now w1, the indirect dimension in a 2D experiment.  The description has also been fixed.
        * Fixes for all of the peak intensity reading functions - the w1 and w2 dimensions were swapped.
        * Updates to the sample scripts for the spectrum.read_intensities user function argument changes.
        * Updates to the user manual for the spectrum.read_intensities user function argument changes.
        * Created the Chemical_shift.test_read_sparky system test for the reading of chemical shifts.  This is for the reading of shifts from a Sparky peak list.  It tests the currently non-existent chemical_shift.read user function.
        * Created some incredibly basic icons for the chemical shift user functions.  These are simply an omega symbol and will need to be replaced by something better in the future.
        * Created the chemical_shift.read user function.  This includes both the front and back end code.
        * Shifted all the modules from lib.software to do with peak lists to lib.spectrum.  This is for a more logical organisation, as these modules are solely used by the lib.spectrum.peak_list module.
        * Renamed all of read_*() functions of the lib.spectrum modules for consistency.  These functions will now be used to read all types of data from a peak list, from the assignments to chemical shifts to peak intensities, and everything in between.
        * Modified the peak list object.  The peak list dimensionality variable is no longer private, and many values of None are now converted to lists of None so that the peak list data is easier to handle.
        * Fix for the proton name in the new Chemical_shift.test_read_sparky system test.
        * Expanded the functionality of the lib.spectrum.sparky.read_list() function.  Now the dimensionality of the peak list is automatically determined, and all peak lists from 1D to 4D are supported.  The chemical shifts are also automatically detected and extracted from the list and placed into the peak list object.  The peak intensity data is also automatically detected,therefore the int_col argument is no longer used.
        * The lib.spectrum.sparky.read_list() function can now auto-detect the peak volume column and use it for intensities.
        * Created the Chemical_shift.test_read_xeasy system test.  This is for checking the reading of chemical shifts from a 2D XEasy peak list.
        * Implemented the reading of chemical shifts in the lib.spectrum.xeasy.read_list() function.
        * Created the Chemical_shift.test_read_nmrview system test.  This, if not obvious from the name, is for checking the reading of chemical shifts from an NMRView peak list.
        * Implemented the reading of chemical shifts in the lib.spectrum.nmrview.read_list() function.
        * Assignments can now contain lowercase letters in Sparky and NMRPipe seriesTab peak lists.
        * Fix for the unit test for the reading of intensities from Sparky peak lists.
        * Updated the nmrPipe processing script in the relax user manual.  This is in response to the post by Troels Linnet at http://thread.gmane.org/gmane.science.nmr.relax.user/1520.  The text has also been expanded to better explain spectral processing.
        * Improvements for the description of the NMRPipe processing script in the R1/R2 chapter of the user manual.
        * LaTeX fix for the curvefit chapter of the user manual.
        * The isInf() and isNan() functions of lib.float can now handle values of None.  If None is encountered, the functions simply return False.
        * The model-free optimisation code now handles minfx returning nothing.  This is due to the fix of bug #21001 (https://gna.org/bugs/?21001) in relax, which is really a fix for an upstream minfx (https://gna.org/projects/minfx/) bug (bug #21090 at https://gna.org/bugs/?21090).
        * Created the Mf.test_bug_21079_local_tm_global_selection system test.  This is to catch bug #21079 (https://gna.org/bugs/?21079).
        * Extended the Mf.bug_21079_local_tm_global_selection system test for all Monte Carlo simulation steps.
        * The model_free.select_model user function GUI element now uses unicode for the model parameters.  The tau character is now used for the tm, te, tf, and ts parameters.  And a superscript 2 is used for the order parameters.
        * The model lists in the model-free GUI auto-analysis now use unicode for the S2 parameters.
        * The peak intensity wizard in the GUI is now more robust.  The wizard_update_ids() method can now better handle missing data.  This is encountered if a user skips the first elements of the wizard.
        * Created Wiz_window.setup_page() for user function wizard pages to allow for simpler GUI tests.  This method can be used to setup any user function wizard page with all its arguments set.  It accepts all keyword arguments and sets these for the wizard page, translating to GUI strings as needed.  This should save a lot of lines in the GUI tests.
        * Simplified the Noe.test_noe_analysis GUI test by using the new Wiz_window.setup_page() method.
        * Python 3 fixes for all of the unicode strings in relax.  Instead of using the u"xyz" notation, now unicode("xyz") is being used.  This works as the relax compat module sets the builtin unicode() function to str() for Python 3, as all strings in Python 3 are unicode and hence both the Python 2 u"xyz" and unicode() code are undefined in Python 3.
        * Defined two new functions called u() in the compat module for better unicode string support.  The two functions are defined differently for Python2 and Python3.  The Python3 function simply returns the text unmodified, as all strings are unicode.  The Python2 function converts the str type to a unicode type.
        * The new compat.u() function is now being used for all unicode strings.
        * All "local tm" text in the GUI now uses a subscript m unicode character as well as the tau character.
        * Created the pipe_control.spectrum.test_spectrum_id() function for checking if a spectrum ID exists.
        * Renamed pipe_control.spectrum.test_spectrum_id() to check_spectrum_id().  A bug in the function was also removed, and the other code in the module now uses this function.
        * Created the pipe_control.mol_res_spin.check_mol_res_spin_data() function.  This will check for the existence of molecule, residue and spin data and raise a RelaxError if none exists.
        * Simplification of the data checks in the pipe_control.spectrum module.  This is using the new pipe_control.*.check*() functions.
        * Huge speed up of the GUI tests by the removal of the N_state_model.test_populations test.  This problem was identified by running the GUI tests with the '--time' flag.  One one test machine, this single test took ~142 seconds to complete when the entire GUI tests took ~242 seconds (i.e. this one test took up to 60% of the whole test suite).  This test comes directly from a system test, but the equivalent system test only takes about 6 seconds to complete.  The difference is due to the slow generation of the user function GUI pages.
        * Created the new RelaxNoPeakIntensityError error object.
        * The compat.SYSTEM variable is now set to 'Windows' when 'Microsoft' is detected.  This is for easier identification of MS Windows systems, as either string could be used.
        * Created the new gui.text module for holding all of the unicode text for the GUI.  This module contains unicode strings for the various analysis types, which are then all defined in one location.  This is for consistency.
        * Converted the model-free user function definitions to use the new gui.text module strings.
        * Shifted the gui.text module to lib.text.gui to avoid a fatal circular import in the GUI.
        * MS Windows fixes for the GUI for missing unicode font glyphs.
        * Added some Mac OS X GUI string fixes for missing unicode characters to lib.text.gui.
        * The size of the model list GUI window can now be changed.
        * Redesign of the model list GUI element.  The wx.ListCtrl element has been replaced by a wx.FlexGridSizer combined with wx.CheckBox and wx.StaticText.  The result is a much nicer formatting of the element.  The checkboxes in the old element displayed slight rendering problems on all operating systems and did not look neat.  The new design is also more flexible in that models of None are now treated as separators in the window.
        * The model list GUI element can now display an optional model description column.
        * Added model descriptions and adjusted the size of the model-free model list GUI elements.
        * Refinements for the model list GUI window.  The font for all text elements is now set.  And the elements of the wx.FlexGridSizer are now vertically centred so that the text of the checkboxes and text elements line up perfectly.
        * The size of the model list GUI window is now automatically set to the best fit.
        * The model list GUI element is now centred after the autosizing.
        * The titles in the model list GUI window now use a smaller font size.
        * Update of the description of the interatom.define user function.
        * Added multi-processor support for Monte Carlo simulations.  This simply involves accessing the multi-processor box singleton and running the processor.run_queue() method within the pipe_control.minimise.minimise() function.  This currently does nothing as the processor queue is always empty.  But if the code in the specific_analyses package is modified to add slave commands to the processor but not execute the run_queue() method, then the Monte Carlo simulations will be automatically parallelised.
        * Updated the spectrum.error_analysis user function backend to use the lib.statistics.std() function.  This simplifies the code.  It affects only the peak intensity error analysis when spectra have been replicated.
        * Created the Structure.test_bug_21187_corrupted_pdb system test to catch bug #21187.  The bug at https://gna.org/bugs/?21187 was reported by Martin Ballaschk (https://gna.org/users/mab).
        * Bug fix for the specific analysis API _data_init_spin() method.  This is used for the API init_spin() method.  This is a latent bug which does not affect any of the current analyses in relax.  It was discovered in the relaxation dispersion branch.
        * Addded a new is_queued() method to the Processor object of the multi package.  This allows the Processor object for the uni and mpi4py multi-processor to be queried to see if any slave commands have been queued.
        * Created a unit test for the lib.linear_algebra.matrix_exponential module.  This module does not exist yet, but it will be used to replace the scipy.linalg.expm() function use in the relaxation dispersion branch.
        * Loosened the lib.linear_algebra.matrix_exponential.matrix_exponential() unit test checks.
        * Implemented the lib.linear_algebra.matrix_exponential.matrix_exponential() function.  This handles square matrices in either complex or real form.
        * Created the lib.check_types.is_complex() function.  This is used to determine if a number is a Python or numpy complex type.
        * The lib.linear_algebra.matrix_exponential.matrix_exponential() function now uses lib.check_types.is_complex().  This fixes the function for complex matrices.
        * Created a new unit test for lib.linear_algebra.matrix_exponential.matrix_exponential() for complex matrices.
        * Fix for the new lib.linear_algebra.matrix_exponential.matrix_exponential() function.  This function now returns a numpy array type rather than matrix type.


    Bugfixes:
        * Bibtex fixes required for proper latex2html compilation.
        * Fix for the Palmer.test_palmer_omp for the different Modelfree4 binaries.  The gcc and pdf binaries are now properly detected and the slightly different results are now correctly checked for.
        * The graphics.fetch_icon() function can now return either the absolute or relative path to the icon.  This is a partial solution for bug #21042 (https://gna.org/bugs/?21042).
        * Fix for bug #21042 (https://gna.org/bugs/?21042).  The docs/latex/fetch_docstrings.py now asks the graphics.fetch_icon() function for the relative path to the icon rather than the absolute path.
        * The fetch_docstrings.py script now asks for the Unix '/' separator through graphics.fetch_icon().  This is a final fix for bug 21042 (https://gna.org/bugs/?21042).  The graphics.fetch_icon() function now accepts the 'sep' argument.  This defaults to os.sep.  But the docs/latex/fetch_docstrings.py script uses the Unix '/' separator to obtain a LaTeX correct path on MS Windows.
        * Modified the create_mc_data() method to partly fix bug #21079 (https://gna.org/bugs/?21079).  Some spins with local tm models remain selected despite not containing any data.  These are handled explicitly.  Instead of a RelaxNoModelError being raised, the method returns None to indicate that something went wrong.
        * Final fix for bug #21079 (https://gna.org/bugs/?21079).  This is the failure of the dauvergne_protocol auto-analysis when the "local tm" global model is selected.  The Monte Carlo create_data() method not skips data from the base_data_loop() if the create_mc_data() method returns None.
        * Fix for bug #21097 (https://gna.org/bugs/?21097).  This was a simple typo.  It has not been encountered before because it is in a rarely encountered RelaxError.
        * Fix for bibtex warning 'Warning--string name "mb" is undefined'.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix for latex bibtex string 'cp' instead of 'cj'.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Another fix for bibtex string 'cp' instead of 'cj'.  Progress sr #3071: https://gna.org/support/index.php?3071 - Implementation of Tollinger/Kay dispersion model (2001).  Following the guide at: http://wiki.nmr-relax.com/Tutorial_for_adding_relaxation_dispersion_models_to_relax.
        * Fix for bug #21187 - the corrupted PDB issue with protons atom numbers of zero.  The bug at https://gna.org/bugs/?21187 was reported by Martin Ballaschk (https://gna.org/users/mab).  The fix was to allow for spin containers in the relax data store to have the same atom number, as long as the atom names are different.
        * Modified the Monte Carlo simulation printout behaviour for the minimisation related user functions.  This is to help in fixing bug #21190 (https://gna.org/bugs/?21190).  This includes the calculate, grid_search, and minimise user functions.  The new multi-processor is_queued() method is used to determine if the optimisation code of the specific analysis has queued rather than run the calculations.  If queued, the 'Simulation X' text will not be printed out.  This avoids printing out all the text at the start before anything has happened.  The specific multi-processor optimisation code must provide it's own printouts when each calculation is complete.

    Changes:
        * Some small clarifications and reordering of the release checklist document.
        * Shifted the pipe_control.structure.superimpose module to lib.structure.superimpose.
        * Shifted the pipe_control.structure.statistics module to lib.structure.statistics.
        * Created the unit test infrastructure for the lib.structure package.
        * Shifted the pipe_control.structure.pdb_read and pipe_control.structure.pdb_write modules to lib.structure.
        * Shifted the pipe_control.structure.cones module to lib.structure.cones.
        * Split the pipe_control.structure.mass module into two with the CoM code going to lib.structure.mass.
        * Removed the data pipe checks from the internal structural object.  This decoupling from the relax data store is in preparation for moving into the lib.structure package.
        * More decoupling of the internal structural object from the relax data store.  Removed the ability of the internal structural object to determine if two atoms are connected by consulting the relax data store.
        * Created the empty lib.structure.internal package for holding the internal structural object.
        * Shifted part of the internal structural object into the lib.structure.internal.models module.  This contains the two classes ModelList and ModelContainer from the pipe_control.structure.api_base module.
        * Shifted part of the internal structural object into the lib.structure.internal.molecules module.  This contains the class MolList from the pipe_control.structure.api_base module.
        * Shifted the MolContainer class from pipe_control.structure.internal into lib.structure.internal.molecules.  This is in preparation for shifting the internal structural object to lib.structure.internal and for the elimination of the unused and no longer useful ScientificPython structural object.
        * Created the empty lib.structure.represent package.  This will be used to hold modules which generate 3D structures as geometric representations of abstract ideas such as tensors, cones, frames, etc.
        * Shifted the lib.structure.rotor module to lib.structure.represent.rotor.
        * Total elimination of the ScientificPython PDB object.  Maintaining this reader was too much effort and the internal structural object has now surpassed the capabilities of the ScientificPython PDB object (for example the internal object is not PDB specific).  And ScientificPython is very much a dead project, largely replaced by the more successful scipy.
        * Merged the structural API base module api_base into pipe_control.structure.internal.  The API base class is no longer needed as the ScientificPython PDB reader has been eliminated.
        * Deleted the unit tests of the structural API base class.
        * Moved the residual pipe_control.structure.api_base module to lib.structure.internal.displacements.  This is because the base module still contained the Displacements class.
        * Docstring consistency in the internal structural object.
        * Shifted the pipe_control.structure.internal module to lib.structure.internal.object.  This is the new location of the internal structural object.
        * Shifted the selection object out of pipe_control.mol_res_spin and into the new lib.selection module.  The dependence on the MoleculeContainer, ResidueContainer and SpinContainer objects have been removed, as this is part of the relax data store.  Therefore all of the private methods (__contains__, __contains_mol_res_spin_containers, and __contains_spin_id) have been deleted.  The contains_*() will need to be used instead.
        * The pipe_control.mol_res_spin functions no longer use the selection object __contains__() method.  All functions now use the contains_*() methods of the lib.selection.Selection object.
        * Shifted parse_token() and tokenise() from pipe_control.mol_res_spin to lib.selection.
        * The lib.selection.parse_token() function is using the new Python way of splitting strings.  This is via the string's split() method.
        * Removed the no longer used parser argument for reading PDB files from some unit tests.
        * Removed the unit test of the parser argument of the structure.read_pdb user function.  The argument no longer exists.
        * Shifted the cone geometric object representation functions to lib.structure.represent.cone.  The structure.create_cone_pdb user function first calls pipe_control.structure.main.create_cone_pdb() which then calls lib.structure.represent.cone.cone().  This allows the pipe_control function to write out the file and add it to the data pipe's results file list.
        * Fixed some name classes in the namespace of pipe_control.structure.mass.
        * Shifted the diffusion tensor structural object code to lib.structure.represent.diffusion_tensor.  The user function routes to pipe_control.structure.main.create_diff_tensor_pdb(), which pulls the tensor info out of the data store, and then calls the diffusion_tensor() function of lib.structure.represent.diffusion_tensor to create the representation, writes out a PDB file, and finally adds the file to the data pipe's results file list.
        * More removals of the now dead parser argument for the structure.read_pdb user function.
        * Removed the parser argument from structure.read_pdb in the stereochemistry auto-analysis.
        * Restored the selection object __contains_spin_id() method as contains_spin_id().  This will allow for faster checks for matches to spin ID strings.
        * Speed ups for the interatom_loop() by restoring some of the code previously deleted.  This spin ID lookup table is being used again, as this is much faster than the string parsing of spin IDs.
        * The frame order analysis is now using the correct centre of mass function.
        * Shifted calc_chi_tensor() and kappa() from pipe_control.align_tensor to lib.alignment.alignment_tensor.
        * Shifted some of the pipe_control.diffusion_tensor functions to lib.diffusion.main.
        * Created the empty lib.software package.  This will be for functions which create input, read output, or control external programs.
        * Shifted and decoupled some of the grace code into lib.software.grace.  This includes most of the write_xy_header() and write_xy_data() functions.  The data store specific part of write_xy_header() has been shifted into pipe_control.grace.axis_setup().
        * Missing import fix for the lib.alignment.alignment_tensor module.
        * Shifted the lib.opendx package to lib.software.opendx.
        * Shifted the lib.xplor module into the lib.software package.
        * Shifted the Bruker Dynamics Centre parsing code into the new lib.software.bruker_dc module.
        * Deleted the completely unused pipe_control.spectrum.Bruker_import class.  This was added by Michael Bieri in Oct 2011, but the code has never been used.  Other, simpler code has replaced its functionality.
        * Created the Ct.test_bug_20674_ct_analysis_failure system test for catching bug #20674.  This was reported by Mengjun Xue <mengjun dott xue att mailbox dott tu-berlin dot de> at https://gna.org/bugs/?20674.
        * Decreased the number of Monte Carlo simulations in the Ct.test_bug_20674_ct_analysis_failure system test.
        * Created the Jw.bug_20674_jw_mapping system test.  This is a modification of the Ct.test_bug_20674_ct_analysis_failure system test for catching bug #20674 (https://gna.org/bugs/?20674).  The test script was duplicated and the small modifications made to convert it into the J(w) mapping analysis.  This now reveals the same bug but for the J(w) mapping analysis.
        * System test speed ups - decreased the number of Monte Carlo simulations in many tests.  Running 500 simulation optimisations in a system test is a total waste of time!
        * Converted the bug_20674_jw_mapping.py system test script to use the self._execute_uf() interface.  This allows the script to be used in the GUI.
        * Created the Mf.test_bug_20683_bdc_inf_values system test.  This is for catching bug #20683 (https://gna.org/bugs/?20683) reported by Mengjun Xue <mengjun dott xue att mailbox dott tu-berlin dot de>.  The problem is due to infinite and NaN values in the Bruker Dynamics Centre file.
        * Ported the changes of r19302 to the consistency testing and J(w) mapping analyses.  This is the code for checking for infinite relaxation rates imported from Bruker Dynamics Centre files.
        * Missing imports of the lib.float.isInf() function.
        * Modified the bug_20674_ct_analysis_failure.py system test script to use self._execute_uf().  This allows the test to operate as a GUI test, which was failing.
        * Created the specific API common method _data_init_spin().  This will be used as a general method for aliasing to data_init() for initialising spin parameters.
        * Added printouts for the select.read and deselect.read user functions to identify the spins affected.
        * Created the new lib.list module with the function count_unique_elements().  This function will be used to determine the unique number of elements in a list.
        * Shifted the Sparky peak intensity reading code to lib.software.sparky.read_list_intensity().  This new function comes from the old pipe_control.spectrum.intensity_sparky() function, but with the spin ID code removed.
        * Shifted the XEasy peak intensity reading code to lib.software.xeasy.read_list_intensity().  This new function comes from the old pipe_control.spectrum.intensity_xeasy() function, but with the spin ID code removed.
        * Docstring fix for the lib.software.xeasy.read_list_intensity() function.
        * Shifted the NMRView peak intensity reading code to lib.software.nmrview.read_list_intensity().  This new function comes from the old pipe_control.spectrum.intensity_nmrview() function, but with the spin ID code removed.
        * Created the lib.software.sparky.write_list() function and associated unit test.  This will be used to create simple Sparky .list files.
        * The relaxation curve-fitting analysis parameters are now all lowercase.  This is to match the other analysis types so that the parameter names are identical to the corresponding variable name.  This is assumed by some of the specific analysis API methods.
        * Removal of junk code in the _assemble_scaling_matrix() relaxation curve-fitting method.
        * Parameter scaling is now functional in the target_function.relax_fit.c code.  Previously the scaling was not being used and the Python to C conversion was broken.
        * The scaling matrix is now converted into a usable list of diagonal elements for the relax_fit C module.
        * Simplified the code of the relax_fit C module.
        * The common spin methods of the specific analysis API now ignore parameters not in the model.  This affects the _data_init_spin(), _sim_init_values_spin(), and _sim_return_param_spin() methods.  The result is that the spin containers no longer hold parameter variables set to None for non-model parameters.
        * Created the pipe_control.plotting module.  This will be used as a base for the plotting of all types of data.  This includes the current OpenDX and Grace modules, as well as future modules.  The determine_functions() function has been added and is used to simplify the pipe_control.grace.get_data() function.
        * The grace.write user function data type argument sequence values have changed.  Instead of 'spin', this can now be 'res_num' or 'spin_num' to specify that either the residue number or spin number should be plotted on the desired axis.  The x_data_type now defaults to 'res_num'.
        * Created the pipe_control.mol_res_spin.count_max_spins_per_residue() function.  This will be used by the plotting module to determine if more than one spin per residue exists.
        * Fixes for the change of the grace.write user function data type 'spin' to 'res_num'.
        * Updated the pipe_control.plotting.determine_functions() function.
        * Added the skip_desel flag to the important pipe_control.mol_res_spin.spin_loop() generator function.  This is used to skip deselected spins within the loop.  As must of the code in relax using the spin_loop() does this anyway, this can be used to simplify many of the spin looping elements in relax.
        * Expanded the relax_fit system test script to produce all types of currently supported Grace graphs.  This is to more extensively test the grace.write user function.
        * Large redesign of the 2D graphing code in relax.  This currently affects only the grace.write user function, but the new infrastructure will make it much easier to expand the graphing abilities and to support other 2D graphing software.  The plotting code has also been significantly simplified.  The pipe_control.grace.get_data() function has been shifted into the pipe_control.plotting module.  It has been split up into the base assemble_data() function with the data assembly shifted to assemble_data_scatter(), assemble_data_seq_value() and assemble_data_series_series().  This split massively simplifies the code by not packing all different graph and set combinations into one.  In addition the auxiliary functions classify_graph_2D(), fetch_1D_data(), get_functions(), and get_data_type() have been created to maximise code sharing between the different assemble_*() functions.
        * Modified the relax_fit system test script to generate a new type of graph.  This is the residue number sequence verses the peak intensity series data (and vice versa) via the grace.write user function.  This is to help in the implementation of this graph type.
        * Created the pipe_control.plotting.assemble_data_seq_series() function.  This is to allow the residue or spin numbering to be plotted against any series type data (lists or dictionaries), or vice versa.
        * Added a link to the PDF user manual from the HTML user manual.  This will affect all pages at http://www.nmr-relax.com/manual/ by adding an icon to the navigation bar pointing to the PDF manual at http://download.gna.org/relax/manual/relax.pdf.
        * The plotting of residue or spin numbers verses values now handles multiple spin types properly.  This is in the pipe_control.plotting.assemble_data_seq_value() function.  The spin name is being used to identify different spin types for the graph sets.
        * The pipe_control.mol_res_spin.count_max_spins_per_residue() function now accepts a spin ID argument.  This can be used to restrict the spins to count.
        * The spin ID string is now being used by the plotting functions.  The spin ID was not being passed into the assemble_data_*() functions.
        * Changed how pipe_control.plotting.assemble_data_seq_value() determines the number of graph sets.  Instead of counting the maximum number of spins per residue, different spin names are now checked across the sequence.  This is needed as a single residue could have a different type of spin.  This was caught by the Mf.test_dauvergne_protocol system test.
        * Modified pipe_control.plotting.assemble_data_series_series() to handle dictionaries with keys as values.  This will be useful in, for example, relaxation dispersion for plotting the dispersion curves.  In this case, the R2eff values are in a dictionary where the keys are the values to plot against.  This is different from the current case where the X and Y data dictionaries are required to have the same keys.  These changes expand the capabilities of the grace.write user function.
        * Formatting change for the auto_analyses __all__ package list.
        * Removed the import of the auto-analysis modules into the auto_analyses package __init__ module.  This import is not needed.
        * The N-state model system test module now imports the auto-analysis to fix an import order error.
        * Added a warning for the spectrum.read user function if a peak intensity of zero is encountered.  This value can cause singular matrix failures in certain optimisation algorithms.
        * The spectrum.error_analysis user function can now be performed on a subset of all spectra.  The subset argument has been added to allow the error analysis to be restricted to a subset of all loaded spectral data.
        * Created the lib.list.unique_elements() function for returning a list with duplicates removed.
        * Shifted the standard deviation code from the Monte Carlo error_analysis() function to the lib package.  The new function lib.stats.std() is now used to simplify the error_analysis() function and allow the code to be reused.  This will be useful for expanding the pipe_control.monte_carlo.error_analysis() function to handle parameters which are dictionaries, for example as in the relax_disp branch.
        * The Monte Carlo error_analysis() function now handles dictionary type parameters.
        * Renamed the new lib.stats module to lib.statistics.
        * Spun out the model list GUI element from the model-free auto-analysis into its own module.  This GUI element is now the gui.analyses.model_list.Model_list class.  This code has been spun out as the GUI element will be used by the relaxation dispersion branch.
        * The gui.analyses.model_list.Model_list GUI element now can have tooltips via the tooltip class variable.
        * Rearrangements of the gui.analyses package.  The new gui.analyses.elements package has been created and the model list and text and spin GUI elements have all been shifted into the package.
        * Spun out the Spin_ctrl analysis GUI element into its own module in gui.analyses.elements.
        * The relaxation time part of the spectra list GUI element can now be turned on or off.
        * The execution of the user function GUI pages can now be delayed.  The create_page() execute flag has been added to disable execution.  This can be later forced with the new on_execute() force_execute flag.
        * Modified the GUI new analysis wizard to return a list of user function on_execute methods.  This will be used in the relax_disp branch and in the future for when a special user function page is added to the new analysis wizard.  This allows the use of user function pages with execution delayed until the analysis __init__() method is being run.
        * Standardisation of the text of the GUI elements of the analysis frames and expansion of the tooltips.  All the text parts of the Spin_ctrl and Text_ctrl elements now end in a colon.  Tooltips are now present on all elements and have been expanded and improved.
        * The Text_ctrl analysis frame GUI elements  now have separate tooltips for the buttons.  This is to give a hint to the user as to what the button does.
        * The model selection GUI analysis element can now have a different tooltip for the button.
        * Added tooltips to the model-free model list GUI elements in the model-free analysis frame.
        * Created the gui.wizards package for holding all of the relax wizards.  The gui.wizard module is now called gui.wizards.wiz_objects.
        * Shifted and merged the NOE and Rx peak intensity wizards into a new module.  The wizards were separate and a part of the analysis frame class objects.  The two wizards have been merged into the gui.wizards.peak_intensity.Peak_intensity_wizard class as most of the code is shared.  This one wizard class will be useful for reusing in the relaxation dispersion branch.
        * The peak intensity wizard class now inherits from Wiz_window.  This allows the class to be a wizard window instead of launching a wizard window from within the class.
        * Small rearrangements in the gui.wizards.peak_intensity module.
        * Alphabetical ordering of the methods in the gui.wizards.peak_intensity module.
        * Simplified all of the peak analysis wizard wizard_update_*() methods.  They now all defer to the wizard_update_ids() method which updates the spectrum ID fields.
        * Simplified the wizard_update_noe_spectrum_type() method as in the previous commit.
        * Fixes for the frq.set user function in the GUI.  The ID list is now set to the spectrum IDs, and the frequency units are no longer all fused into one string.
        * Unicode is now used for the tau symbol in the model-free model parameter lists in the GUI.  This is only when modifying the models to optimise, which shouldn't be changed anyway.
        * Removed the 'string' from 'Spectrum ID string' in the spectrum list GUI element.  This is a GUI - the word string is meaningless here!
        * The delay times column string now specifies seconds in the spectrum list GUI element.
        * Formatting improvements for the relaxation data list GUI element.  The data type column entries are now descriptive and use subscript.
        * More unicode strings are used for the GUI for subscripts and Greek letters.
        * Fixes for the R1 and R2 GUI analyses for the recently introduced unicode subscript characters.  There is now self.label for a pure string version and self.gui_label for the fancier unicode version.
        * The frq.set user function 'id' argument is no longer read only - this was causing test suite failures.
        * Removed a nasty kludge for releasing the execution lock on failure.  This kludge, after the bug fix for https://gna.org/bugs/?20756, was causing failures in the test suite.
        * Changed the 'Execute relax' button in all analyses in the GUI to 'Execute analysis'.  It makes no sense to execute relax as relax has been executing during the analysis initialisation and the user setting up all the data for the analysis.  This is a remnant of ancient design of Michael Bieri's GUI being a separate program to relax, which would execute relax with the click of this button.
        * Restored the Py_INCREF() function call in the relaxation curve-fitting C module.  This was deleted at r12632 along with Py_XDECREF() and Py_DECREF() calls.  The absence of a Py_INCREF() function call causes the module to crash the Python interpreter under certain conditions.  The problem was found in the relax_disp branch.
        * Clean up of unused headers and declarations in the exponential curve C module.
        * The relax_fit C module setup() function now uses the Py_RETURN_NONE macro to terminate.  This macro does exactly what the old code does anyway.
        * Removed an unused declaration in the relax_fit C module setup() function.
        * Increased the maximum number of relaxation times for the relax_fit C module to 50.
        * Shifted the C array creation to the relax_fit C module header.  The params, values, sd, relax_times, and scaling_matrix C arrays are now declared and allocated in the header file rather than using malloc() calls in the setup() function.  This is to attempt to remove a memory leak.  The arrays are now of fixed length and reused for each setup() call.  These, as well as the other variables declared in the header, are no longer declared in the functions.
        * Improved the Python and C documentation of the functions of the relax_fit C module.
        * Converted the Py_BuildValue() calls to PyFloat_FromDouble() in the relax_fit C module.  This doesn't change much.
        * Documentation improvements for the back_calc_I() function of the relax_fit C module.
        * The exponential C file now uses the exp() function from math.h rather than Python.h.  This file is independent from Python.
        * The numpy include is no longer used for the compilation of the C modules.  Numpy is not used at all in the C modules, so this just adds an annoying dependency for those who need to compile the module themselves.
        * Removed some bad calls to status.exec_lock.release().  This commit may have to be reverted in the future.  The problem is that the execution lock is not being held when these calls are made.  The calls were added as a kludge to handle certain situations where the execution lock was not released.  There may be cases were this behaviour is still needed.
        * Added a developer script for testing of memory leaks in the relax_fit C modules.
        * Removed the numpy dependence from the manual C module compilation script.
        * Created the lib.mathematics relax library module.  This currently contains two functions, order_of_magnitude() and round_to_next_order().
        * Added unit tests for the lib.mathematics module.
        * The relax_fit analysis now uses lib.mathematics.round_to_next_order() for the scaling matrix.  This allows the optimised I0 value to be better understandable in the printouts.
        * Created the new Value system test class with the first test Value.test_value_copy.  This test demonstrates some pretty large bugs in the value.copy user function.
        * Modified the Value.test_value_copy system test to check the copying of errors as well.
        * Added the error flag argument to all of the specific analysis API set_param_values() methods.  This will allow parameter errors as well as values to be set.
        * The Value.test_value_copy system test now checks all of the values and errors.
        * Added the error flag argument to the value.set user function.  This will allow for parameter errors to be set by the user.
        * The specific analysis API _return_value_general() method now returns errors even when values are missing.
        * The internal structural object PDF file creation now writes out http://www.nmr-relax.com.  Previously the link http://nmr-relax.com was written out.
        * Diffusion tensor PDB file fixes for the internal structural object changes.  This is because the relax website link is now written into the PDB file as http://www.nmr-relax.com rather than http://nmr-relax.com.  This fixes the diffusion tensor system tests.
        * Converted all of the specific analysis modules into packages.  The model-free and steady-state NOE analyses were already packages, and this now brings all other analyses in line with the package design of specific_analyses.  The only change is that the files specific_analyses/x.py have been shifted to specific_analyses/x/__init__.py and the __all__ package variable added.
        * Epydoc docstring fixes for the compat module.
        * The peak intensity wizard can now function remotely when the spins are not named.  This will be needed for the GUI tests to allow the Question() call to be bypassed and still adding the spin.name user function as the first page of the wizard.  The key for spin.name page has also been fixed so that the page can be accessed.
        * The timing of individual tests in the relax test suite can now be printed out.  The new command line argument --time has been added which, when supplied with one of the test suite arguments, will cause the time required to complete each individual test to be displayed.  Instead of just printing the characters '.', 'F', and 'E' for each test, now these characters are postfixed with the time in seconds, the name of the test and ending in a newline character.
        * Big speed up of the test suite by skipping a large number of redundant Frame Order system tests.  These are tests of using only PCS or only RDC data.  These tests are still active for the pseudo-ellipse just to make sure that a whole missing data type can be handled.
        * Suppressed the reporting of skipped tests in the test suite if the module is set to None.
        * The preview button in the file selection elements of the user function windows can now be disabled.  This is via the new wiz_filesel_preview argument being set to False.
        * Merged the frq.set and temperature user functions into the new spectrometer user function class.  The frq.set user function is now called spectrometer.frequency and temperature is now spectrometer.temperature.  To match these changes, the cdp.frq variable is now called cdp.spectrometer_frq.
        * Modified the spectrometer.frequency user function so that a frequency list and count is stored.  These are the new cdp.spectrometer_frq_list and cdp.spectrometer_frq_count variables.  This will allow various parts of relax which assemble frequency information to be simplified and made more consistent.
        * Created basic SVG and PNG graphics for the spectrometer user function class.  The spectrometer is black so as not to offend Bruker, Varian, or Jeol users by avoiding a colour from one of these companies.
        * The pipe_control.spectrometer.get_frequencies() function can now return MHz or Tesla units.
        * Renamed the functions of the pipe_control.spectrometer module.  The frequency() and temperature() functions are now called set_frequency() and set_temperature().
        * Added backwards compatibility support for the spectrometer frequency list and count.  This is needed for old relax state files.
        * A whitelist is now being used to limit the number of frame order GUI tests to 1.
        * Shifted all frequency data handling associated with relaxation data to pipe_control.spectrometer.  This includes the deletion of the relax_data.frq user function as this replicates the behaviour of spectrometer.frequency.  A number of functions from the pipe_control.relax_data module have changed:  frq() has been deleted as it is replaced by pipe_control.spectrometer.set_frequencies(); frq_checks() has been shifted to pipe_control.spectrometer.frequency_checks(); frq_loop() has been shifted to pipe_control.spectrometer.loop_frequencies(); num_frq() has been deleted as the new variable cdp.spectrometer_frq_count contains this info.  Two new functions in the pipe_control.spectrometer module have been added to remove the functionality from pipe_control.relax_data.  These are copy_frequencies() and delete_frequencies().
        * The molmol.macro_run user function file argument now has a description.
        * Huge speed up of the system tests for the loading and creation of model-free saved states.  The OMP files used for the system test have been truncated from 134 to 7 spins, changing the timing of 6 system tests from 11-13 seconds to less than 0.5 seconds each.
        * All of the binary file arguments for the user functions now are file selection GUI elements.  The GUI user function wizard pages now have file selection buttons for selecting the executable to run.  These all have the preview button disabled.  The results.read and state.load GUI elements also have the preview button disabled.
        * The user function 'prompt' description elements as now displayed in the GUI wizard page.
        * The monte_carlo.error_analysis user function can now handle parameters which are lists.
        * Added the ability for specific analyses to override the optimisation constraint algorithm.  The default is still the 'Method of Multipliers', but if the constraint_algorithm() method returns a different string, then that will be used to select the algorithm.  This allows the 'Log Barrier' method in minfx to be used.
        * The value.display and value.write user functions can now handle list and dictionary type parameters.
        * Added two methods to the specific analysis common API class.  These are the _model_type_global() and _model_type_local() methods for always specifying that the model type is global (i.e. at the level of the data pipe) or local (i.e. there can be multiple clusters of models).
        * Added some more functions to the lib.statistics module.  These include the bucket() function for creating a discrete distribution from a list of floating point numbers, and the gaussian() function for calculating the probability of a point on a Gaussian distribution.
        * Added a directory and files for testing the white noise in relaxation data.  This includes scripts and graphs.
        * The initial parameters are now the real parameter rather than the optimised ones.  This is for the script for testing white noise in relaxation data.
        * The spectrum.peak_intensities is now more robust when reading in a generic formatted file.  Firstly there is a check that the intensity column number has been supplied.  And then there is a checks that all relevant data could be extracted from each row of the file.  This replaces traceback errors with RelaxErrors explaining the problem if the user inputs bad data or forgets the intensity column argument.
        * Changed the "Execute analysis" button text back to the original "Execute" text of the old relax GUI.
        * Added the 'test.seq' file from bug report #20873 (http://gna.org/bugs/?20873).  This is from Troels E. Linnet (http://gna.org/users/tlinnet).  The bug report and link to http://thread.gmane.org/gmane.science.nmr.relax.user/1452 explains the contents.  The file will be used to construct a system test to catch the bug.
        * Created the Peak_lists.test_bug_20873_peak_lists system test to catch bug #20873.  This was reported by Troels E. Linnet (http://gna.org/users/tlinnet) at https://gna.org/bugs/?20873.  The test has been created by copying the user function calls from the original bug report and slightly modifying them to suite a 'relax_fit' analysis type.
        * Fix for the Peak_lists.test_bug_20873_peak_lists system test.  The spectrum IDs are now strings.
        * Added checks of the peak intensities to the Peak_lists.test_bug_20873_peak_lists system test.
        * The spectrum.integration_points page in the peak analysis GUI wizard has been fixed.  It is only shown when volume integration is selected with no replicated spectra.
        * Removed a debugging printout which is killing the relax unit tests in Python 3.
        * Added an EPS version of the 128x128 pixel spectrometer icon.  This is for use in the relax manual.
        * Added a README file for the relax 128x128 icons describing how the EPS files should be created.
        * Updated the spectrometer 128x128 icon to be of the correct size and colour.
        * Added a README file to the graphic/analyses directory describing how to create the EPS files.
        * Merger of the dipole_pair and interatomic user function classes.  The functionality of these two classes overlaps significantly.  And the dipole_pair user functions are not related to magnetic dipole-dipole interactions.  Therefore all the user functions from both classes were shifted into the new interatom user function class.  This change will affect almost all relax scripts but, as this will form part of the relax 3 release, script breakage should be expected anyway.
        * Removed the pipe_control.dipole_pair module as its contents is now in pipe_control.interatomic.
        * Removed the dipole_pair module from the pipe_control package __all__ list.
        * Merged the interatom.create user function into interatom.define.  These user functions had overlapping functionality which would be confusing for a user.
        * Added polish to all of the interatom user function docstrings.
        * Improved the functionality of the interatom.read_dist user function.  The file data is now stripped using lib.io.strip to remove comments and blank lines.  And now if the iteratomic data container cannot be found, it is created instead of raising a RelaxError.
        * Improvements to the RelaxZeroVectorWarning - the warning message was terribly out of date.
        * Polish for the rdc.read user function.  Comment lines and blank lines are now removed to suppress useless warning messages about these lines containing no valid data.
        * Added some basic initial relax icons for J couplings.
        * Created some basic initial GUI wizard graphics for J couplings.
        * Modified the titles of all the auto-analysis GUI elements.  The text 'Setup for' has been removed as it is meaningless.
        * Added more emphasis on the titles of the auto-analysis GUI elements.  There is now more space below the title, and a different font (16pt roman italic) is being used.
        * Removed some now irrelevant information from the rdc.read user function docstring.
        * Removed a false prompt example from the rdc.read user function docstring.
        * Created an entire new user function class for handling J couplings in the relax data store.  This derives from the RDC user function modules.  The following functions have been created:  j_coupling.copy, j_coupling.delete, j_coupling.display, j_coupling.read, and j_coupling.write.
        * Added a check for the RDC data type to the rdc.read user function.
        * The rdc.read user function can now handle T = J+D type data.  Support for this in the specific analyses is yet to be added.
        * Fixed for the rdc.read, j_coupling.read and interatomic.read_dist user functions.  Comment lines are no longer removed, as it is impossible to tell a comment line from a spin ID string.
        * Split up the specific_analyses.n_state_model package into modules.  The new data and parameter modules have been created by shifting out method from the __init__ module and converting them into functions of the two new modules.  This is to simplify the package.
        * Shifted another method from the N_state_model class to the specific_analyses.n_state_model.data module.
        * Added support for the T = J+D RDC data type to the N-state model target function.  The J couplings are sent into the target function class when the 'T' RDC data type is encountered.  These measured values are then added to the back-calculated RDC values to produced T(theta) which is then compared to T via the chi-squared function.
        * Fix for the new specific_analyses.n_state_model.data.opt_uses_j_couplings() function.  The cdp.rdc_data_types appears not to have all alignments IDs within it.
        * Removed the check for Numeric Python in the dep_check module.  This Python module not been used within relax for the better part of a decade.  This check is not needed.
        * Added the j_coupling module to the pipe_control __all__ list.
        * Fix for the pipe_control.rdc.q_factors() for T = J+D type data.  The Q factor normalisation was incorrect, as the J coupling should be subtracted from T first.
        * Unit test fixes for the N-state model.  This is needed due to the recent package rearrangements.
        * Removed the absolute argument for all of the lib.alignment.rdc functions.  This should be performed at the level of the target function, as mathematical operations may be required prior to taking the absolute value.
        * Fixes for the N-state model target functions for the lib.alignment.rdc changes.  The absolute value is now calculated within the target function rather than when back calculating the RDCs.
        * Errors are now handled correctly for the N-state model when T = J+D values are used for the RDCs.  The error is the square root of the average variance of the RDC error and J coupling error.
        * The RDC back-calculation function now supports T = J+D values.
        * Created the N_state_model.test_absolute_T system test.  This is for checking the optimisation of absolute T=J+D values to find alignment tensors.
        * Epydoc docstring fix for the RelaxTestResult.write_time() method.
        * Created a script to look through the entire relax source tree for unused imports.
        * Removed a large amount of unused imports throughout the relax code base.  These were identified by the new ./devel_scripts/find_unused_imports.py script together with pylint.
        * Fixes for the pipe_control.rdc module for when the structure cdp.rdc_data_types is missing.
        * Improvements to the devel_scripts/find_unused_imports.py script.
        * More cleanups of unused imports throughout relax.
        * Fixes for how the devel_scripts/find_unused_imports.py script runs pylint.
        * More cleanups of unused imports throughout relax.
        * Fixes and expansion of the test_suite.unit_tests._lib package __all__ list.
        * Fixes and improvements to Gary Thompson's unit_test_runner.py script.  The printouts have been improved and the script can now handle more than 3 levels of directories for a package.
        * The unit_test_runner.py script now defaults to verbose mode.
        * More cleanups of the unit_test_runner.py script.
        * Added a printout to the unit_test_runner.py if the TestCase class cannot be found.  This normally continued the test loading silently without warning that the TestCase class name is missing or incorrect.
        * Missing import in the unit test module for the lib.frame_order.matrix_ops module.
        * Shifted the spin_id_to_data_list() function from pipe_control.selection to lib.selection.  This is because the selection object requires this function, and the function has nothing to do with the relax data store.
        * Lots of import cleanups including removal of '*' imports, missing imports, and unused imports.
        * Small change to the find_unused_imports.py printouts.
        * Large removal of unused imports throughout relax found using the devel_scripts/find_unused_imports.py script.
        * Clean up of all the imports in the relax code base.  This is mainly alphabetical reordering of the imports required due to the huge layout changes in the trunk.
        * Shifted the user function initalisation.  This is from the import of the user_functions package to the package initialise() function.  This is for saner importing dependencies in the relax sources.
        * The lib.io.open_write_file() function now catches file names of None and raises a RelaxError.  This is useful for the GUI if the user forgets to select a file name.
        * The rdc.corr_plot user function can now handled T=J+D type data.
        * The N-state model analysis can now handle RDC data of mixed D and T=J+D.
        * Added support for mixed RDC data types per alignment.  This is to allow, for example, one bond RDC values of the 'D' data type and two bond RDC values of the T = J+D data type to be loaded for the same alignment ID.  This is now handled in the N-state or ensemble analysis by handling a different RDC data type per RDC value.
        * The Peak_lists.test_bug_20873_peak_lists system test is now skipped if the C modules are not compiled.  This test requires the presence of the C modules.
        * Added a completely empty PNG image to use in the new analysis GUI wizard for blank buttons.  This will be used in the relax_disp branch to eliminate a Mac OS X only bug.
        * Added the scripts for backing up the relax SVN repository and mailing lists to the repository.  This is to make it easier for others to set up the backups on their systems.
        * Added comments to the backup scripts to make it easier to use them.
        * Added the listings package to the relax user manual LaTeX file.  This will be used to improve the formatting and look of relax scripts in the manual.
        * Started to convert the relax user manual to use the lstlisting environment for scripts.  This is to prettify the scripts in the manual.
        * Improvements to the script UI section of the NOE chapter of the user manual.  The lstlisting environments now have the correct numbering to match the script at the start,comments have been copied into the split up script elements, and a few comments improved.
        * The NMRPipe script in the relaxation curve-fitting chapter of the manual now uses lstlisting.  The language has been explicitly set to csh to override the global default of Python.
        * Converted all of the relaxation curve-fitting chapter of the user manual to the lstlisting environment.  This is for all parts of the script UI section of the chapter.
        * Converted all of the model-free chapter of the user manual to the lstlisting environment.  This is for all parts of the script UI section of the chapter.
        * Converted all of the J(w) mapping chapter of the user manual to the lstlisting environment.  This is for all parts of the script UI section of the chapter.
        * Converted all of the Consistency testing chapter of the user manual to the lstlisting environment.  This is for all parts of the script UI section of the chapter.
        * Created a new listings language definition for relax for the user manual.  This is for better highlighting of relax scripts and code in the relax manual.
        * Added an EPS version of the 128x128 J coupling icon for use in the relax user manual.
        * Removed some junk text from the relax script text in section 6.3.8 of the user manual.
        * The relax language definition is now auto-generated by the fetch_docstrings.py script.  This is for use in the relax user manual using the listings package.  The fetch_docstrings.py script now creates the docs/latex/script_definition.tex file.  This is used by the relax.tex file via an \include{} statement.  This setup allows all of the relax user functions to be dynamically set as keywords for the relax language definition.
        * Converted all of the Development chapter of the user manual to use the listing package.  This is for all of the code examples, which are now much more colourful.
        * Small typo fix for the relaxation curve-fitting chapter of the user manual.
        * Fixed some out of date script code for the relaxation curve-fitting chapter of the user manual.
        * Added a section label to the relaxation curve-fitting chapter of the user manual.
        * Adding a test data file in NMRPipe SeriesTab format.  Progress sr #3043: (https://gna.org/support/index.php?3043) - Support for NMRPipe seriesTab format *.ser.  A file in NMRPipe SeriesTab format is added to the test-suite for further development.
        * Test function for NMRPipe SeriesTab format implemented.  Progress sr #3043: (https://gna.org/support/index.php?3043) - Support for NMRPipe seriesTab format *.ser.  An assertEqual test is implemented for the reading of NMRPipe SeriesTab format.  The standalone call is: relax -s Peak_lists.test_read_peak_list_NMRPipe_seriesTab
        * Adding a NMRPipe function file in the folder lib\software\nmrpipe.py.  Progress sr #3043: (https://gna.org/support/index.php?3043) - Support for NMRPipe seriesTab format *.ser.  Initial file for: lib\software\nmrpipe.py.  This file will hold the function calls handling NMRPipe SeriesTab format.
        * Fix for commit (http://article.gmane.org/gmane.science.nmr.relax.scm/18004).  The spin naming was wrong.  Progress sr #3043: (https://gna.org/support/index.php?3043) - Support for NMRPipe seriesTab format *.ser.  'spin_id' keywords should be supplied different.  Ex: spin.name(name='NE1', spin_id=':62').
        * Autodetect format implemented for NMRPipe SeriesTab format implemented.  Progress sr #3043: (https://gna.org/support/index.php?3043) - Support for NMRPipe seriesTab format *.ser.  The file is determined a NMRPipe SeriesTab if the first two words of the first line is: REMARK SeriesTab.
        * Update of the rotation matrix example in the intro chapter of the user manual.  The function is now in lib.geometry.rotations.euler_to_R_zyz().  The example has also been converted to the lstlisting environment for better formatting.
        * The relax prompt strings and help system are now keywords for the relax listings package definition.  The prompt strings "relax>" and "relax|" are now recognised as keywords and are coloured blue.  The help system has been added as a normal Python keyword for highlighting.
        * Converted all relax prompt examples in the intro chapter of the manual to the lstlisting environment.  This is simply for a more colourful representation.
        * The prompt examples in the user function chapter of the manual now use the listing environment.  This is via the fetch_docstrings.py script and results in much better formatting of these subsections.
        * Added function destination for auto-detected NMRPipe SeriesTab format.  Progress sr #3043: (https://gna.org/support/index.php?3043) - Support for NMRPipe seriesTab format *.ser.  Auto-detected NMRPipe SeriesTab format make function calls to the file: lib\software\nmrpipe.py in function nmrpipe.read_list_intensity_seriestab().
        * Imported the missing lib.software.nmrpipe module into pipe_control.spectrum.  Progress sr #3043: (https://gna.org/support/index.php?3043) - Support for NMRPipe seriesTab format *.ser.  Expected modules for use in lib\software\nmrpipe.py is imported.
        * Release checklist minfx and bmrblib version update to the newest versions.
        * Spacing fix in an import statement (found using the 2to3 conversion program).
        * Added the relax wiki backup script for dumping the MySQL database contents locally.  This is from http://article.gmane.org/gmane.science.nmr.relax.devel/4163.
        * Added the script from Troels Linnet for backing up the relax wiki via FTP.  This is from the post http://article.gmane.org/gmane.science.nmr.relax.devel/4168.
        * Added a link to Troels' post to the relax-devel mailing list to the relax wiki FTP backup script.  The link is http://article.gmane.org/gmane.science.nmr.relax.devel/4168
        * The relax info printout now works in the absence of the bmrblib module.
        * Added some Oxygen icons for a boolean GUI input element.  The media-record-relax-green.png files are the media-record.png files with the hue set to 117.
        * Created a boolean input element for the auto-analyses of the GUI.  This simply turns on and off.
        * The boolean GUI auto-analysis input element now has a SetValue() method.
        * Completed NMRPipe SeriesTab reader.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.  Completed NMRPipe SeriesTab reader for assignment according to SPARKY format.  Changes implemented according to: http://article.gmane.org/gmane.science.nmr.relax.devel/4120.
        * Extraction of NMRPipe SeriesTab changed.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.  The Extraction of NMRPipe SeriesTab data is changed in pipe_control/spectrum.py in the read() function.
        * Added flag for single or multiple extraction of spectrum.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Flag change added to reading of NMRPipe SeriesTab.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Some small edits to the intro chapter of the relax user manual.
        * Many improvements to the indexing in the relax user manual.
        * Removed the flag for single_spectrum.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Fixed wrong reference to Sparky format.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Modfied the intensity list to handle intensities for all spectra per spin.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Fixed the extraction of NMRPipe seriestab data in pipe_control.spectrum.read().  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Fix for handling reading spin of type heteronuc='NE1' and proton='HE1'.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Adding NMR seriesTab data file for a multiple column / multiple spectrum formatted file.  This file is from https://gna.org/support/download.php?file_id=18618 attached to the support request https://gna.org/support/?3043 by Troels Linnet.  This is if the command "seriesTab -in ../../peaks.dat -out seriesTab_multi.ser -list nmrfiles.list -sum -dx 1 -dy 1" where nmrfiles.list contains file reference to 10 .ft2 files.
        * Fix for unit test of nmrpipe.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Replacing a pointer-reference structure to an empty creation of list of lists.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * The ID of spins in seriesTab_multi.ser was not formatted correctly to SPARKY format.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Added system test for reading of a multi column formatted NMRPipe seriesTab file.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.  Generated the reference data in Excel, for the system test.  The spectrum ID's are auto generated by supplying the keyword spectrum_id='auto'.  The first few tests was matched against integers rather than floats. Adding '.0' to the end of each number.  Spaces added after the commas in the self.assertAlmostEqual() calls.  The 2to3 conversion program (for Python 2 to Python 3 conversion) highlights this issue.
        * Added check for number of supplied spectra ID's and the number of returned intensity columns.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Made it possible to autogenerate spectrum ID's, if spectrum_id='auto'.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Remove from datalist where empty list starts. These are created where spins are skipped for ID = '?-?'.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Moved checks for matching length of spectrum IDs and intensities columns.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Moved the adding function of adding the spectrum id (and ncproc) to the relax data store.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.  Shifting it to later will prevent the cdp.spectrum_ids list to be populated after the user calls the user function incorrectly.
        * Added epydoc documentation in pipe_controlspectrum.read() when supplying keyword 'auto'.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Added GUI description for when supplying 'auto' to the spectrum_id.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Added a stub GUI describtion in the File formats, for NMRPipe seriesTab.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.
        * Fix for two spaces are used after a period in documentation.  Progress sr #3043: (https://gna.org/support/index.php?3043) - support for NMRPipe seriesTab format *.ser.  relax uses the double space for easier for the eyes to pick up the sentence structure.
        * The relax user manual is now broken into parts.  The higher level LaTeX part command is now used to group related chapters.  This should make it easier for users to navigate this huge thing.
        * Creation of the optimisation chapter of the relax user manual.  The main text of this chapter originates as part of the model-free chapter.  As this most of this text was not model-free specific, it has been spun out as its own chapter.  Text has also been taken from the "Optimisation of relaxation data – values, gradients, and Hessians" chapter.  The indexing for the optimisation topics has also been improved.
        * Changed the chapter layout of the relax user manual.  The development chapter has been moved forwards.
        * Fix for the spectrum.read_intensities user function docstring.  Grammatically, the text "spectrum ID's" should be "spectrum IDs".  The problem though was that this text was strangely causing the user manual compilation to fail.
        * Added subsubindexing for the optimisation algorithm index entries.
        * Added extensive cross-referencing to the index of the relax user manual.
        * Added some hyphenation rules for better formatting in the user manual.  For this, the external hyphenation.tex has been created.
        * Better indexing in the relax user manual.  The imakeidx LaTeX package is now used instead of makeidx, and the hyphenation has been improved.
        * Lots of spelling fixes for the relax user manual.
        * Updated the minimum Python version from 2.3 to 2.5 in the user manual.
        * Epydoc docstring fix for the pipe_control.spectrum.read() function.  The text "Z_A{i}" causes problems when compiling the API documentation, so it has been changed to "Z_Ai".
        * Python 3 fix for the new test_suite.clean_up module.  The exceptions Python module does not exist in Python 3, so instead the relax compat.builtins object is being used to store the WindowsError variable of None.
        * Added a paragraph to the installation chapter of the manual about not supporting the EPD.


    Bugfixes:
        * Fix for bug #20674 (https://gna.org/bugs/?20674) - the failure of the consistency testing analysis.  This was reported by Mengjun Xue <mengjun dott xue att mailbox dott tu-berlin dot de>.  The problem was that the first residue did not have a single proton 'H' in the PDB file, and therefore the dipolar relaxation interaction was not set up.  The overfit_deselect() method of the consistency testing specific API was not checking for this.  The method is now much more like that of the model-free specific analysis.
        * Fix for the model-free analysis specific overfit_deselect() method.  The tests for the presence of dipolar relaxation was not correct and was non-functional.
        * Fix for the J(w) mapping analysis matching that for the consistency testing.  The overfit_deselect() method is now identical to that of the consistency testing analysis.
        * Fix for bug #20683 (https://gna.org/bugs/?20683) - the infinite and NaN data in Bruker DC files.  This was reported by Mengjun Xue <mengjun dott xue att mailbox dott tu-berlin dot de>.  The model-free specific overfit_deselect() method now checks for infinite relaxation data and deselects the spin if such data is encountered.
        * Fix for the analysis specific API common method _data_init_spin().  The data types are now correctly checked - they are not strings but types.
        * Fix for the relaxation curve-fitting _assemble_scaling_matrix() method.  The intensity scaling was never activated before due to a lower vs. uppercase parameter name mismatch.  This scaling is now correctly set up as the previous code assumed cdp.relax_times was a list whereas it has been a dictionary since the early 1.3 releases.
        * The grid search bounds for the relaxation curve-fitting are no longer affected by scaling.  The parameter scaling recently activated revealed a bug in the lower and upper data structures for the grid search in that these were continuously scaled down.
        * Fix for the target_functions.relax_fit C module - the scaling was incorrectly performed.
        * Fix for the relaxation curve-fitting _back_calc() method for the changes to the C module.  The setup() method requires that the scaling matrix is converted to a list of the diagonal elements.
        * Fix for the analysis specific API common _return_value_general() method.  The value of None is now handled properly when a simulation value is asked for.
        * Restored the default behaviour of the spin_loop().  The skip_desel flag is now functional and defaults to False.
        * Fix for the relax_times and intensities parameter definitions for specific_analyses.relax_fit.  These are dictionaries, not lists.
        * Fix for the spectrum.error_analysis user function for replicated spectra and subsets.  A second call to spectrum.error_analysis was removing the results from the first call.  This is now avoided.
        * Bug fix for the right click popup menu in the spectra list GUI element.  This affects the NOE, R1, and R2 analyses.  The actions of the menu items were all mixed up.
        * Fix for the nasty bug #20756 (https://gna.org/bugs/?20756).  The problem was that the global execution lock was not always released by a relax script when certain errors are raised during the script execution.  This does not occur for all types of error though.  Now the release of the lock has been shifted into the 'finally' statement to absolutely force lock release.
        * Big bug fix for a memory leak in the relaxation curve-fitting C module.  Proper reference counting is used for the temporary 'element' Python objects used in the conversion between Python and C objects.  The use of the Py_CLEAR() macro removes the memory leak.  However the number of references as seen by sys.gettotalrefcount() in a debugging Python version keeps rising and might be a problem in the future.
        * Big bug fix for the value.copy user function - it is now functional again.
        * Bug fix for the value.copy user function.  The user function can now handle parameter errors, and the values are set in the correct data pipe.
        * Bug fix for an incorrect print statement in the N_state_model.test_paramag_centre_fit system test.  This is in the script, and was uncovered using WinPython by Troels E. Linnet (http://gna.org/users/tlinnet) via the relax system tests at http://thread.gmane.org/gmane.science.nmr.relax.devel/3863.  The Python bug was detailed at http://thread.gmane.org/gmane.science.nmr.relax.devel/3863/focus=3867.
        * Fix for the package checking as part of the unit tests.  This was identified from the bug report #20820 (https://gna.org/bugs/?20820) submitted by Troels E.  Linnet (https://gna.org/users/tlinnet).  The problem was that on some systems, the full path is required for checking the presence of the directories which are the sub-packages of the main package being checked.  The result was that checking for the package in the __all__ list was skipped.  Note that this change does not fix the bug reported.
        * Fixes for the Jw.test_calc system test - the spectral density value comparison is now significant.
        * Bug fix for the pipe_control.spectrometer.get_frequencies() function.  The units argument was incorrectly referenced.
        * Fix for bug #20820 (https://gna.org/bugs/?20820).  Solution found - 'software' was not mentioned in __init__.py, and failed at import.
        * Partial fix for bug #20873 (https://gna.org/bugs/?20873).  The spectrum_id argument for the spectrum.read_intensities user function can now be both a string and a list of strings.
        * Fix for bug #20873 (http://gna.org/bugs/?20873).  This was reported by Troels E. Linnet (http://gna.org/users/tlinnet).  The ability to load multiple peak intensities from a single generic formatted file has been correctly implemented.  This involves added checks to make sure that the user supplies reasonable arguments and to then loop over the intensity column argument.
        * Python 3 fixes via the 2to3 program.
        * Bug fix for the value.write user function for list or dictionary type data.  This is for the case where the variable of one spin is set to None rather than a list or dictionary type.
        * Bug fix for the Sequence GUI input element.  This complete the removal of bug #20873 (https://gna.org/bugs/?20873).  The problem was that the gui_to_str() function was not failing to convert the string into a string list, so the list was deemed as a single string.  Now the first character of '[' or '(' for lists or tuples are now searched for instead of relying on the conversion to trigger an error.
        * Fixes for the value.write user function for simple parameter values of None.  This is a recently introduced bug which causes a complete failure of the user function is the parameter for any spin is None.
        * Fix for bug #20888 (https://gna.org/bugs/?20888), the autoscaling of Grace graphs.  This solution was mentioned in the post at http://thread.gmane.org/gmane.science.nmr.relax.devel/3920/focus=3930.  Instead of using minimum and maximum values for the axes in the Grace graphs produced by the lib.software.grace module, which was the old solution for having the graphs scaled to reasonable values, instead the '@autoscale' command is appended to the end of all graphs.  This is performed by the write_xy_data() function.
        * Bug fix for the running of the test suite in the relax GUI.  The fix of r19727 was extended to apply to the GUI as well.  Too many arguments were being sent into TextTestRunner Python class on certain Python versions (3.1 and <= 2.6).
        * Big bug fix - the relax execution lock now truly supports nesting.  This fixes bug #20891 (https://gna.org/bugs/?20891) reported by Troels Linnet (https://gna.org/users/tlinnet).  Scripts can now be executed from the GUI.  Note that this is a very dangerous fix.
        * Completed the fix for bug #20889 (https://gna.org/bugs/?20889).  The problem was that the spectrum.read_intensities user function was incorrectly updating the cdp.spectrum_ids list when the spectrum_id argument is set to a list.  The list of IDs was being set as a single element of cdp.spectrum_ids, causing problems with the GUI when updating the ComboBox choices and then subsequent setting of the spectrum IDs.  This bug and fix is independent of the relax_disp branch, despite being uncovered there and being caught by the Relax_disp.test_bug_20889_multi_col_peak_list GUI test in that branch.
        * Bug fix for the GUI element for the interatom.define user function.  The special spin ID GUI elements can not be set to the get_spin_ids() function as then SetValue can no longer work for IDs not in the list.
        * Fixes for the TestCase class names for a number of lib package modules.  As the test class name was incorrect, previously the test suite was skipping these silently.  This was dangerous.
        * Fixes for the unit tests of the lib.selection module.  The contains_*() methods now should be used.  And the test_Selection_ful_spin_id() unit test has been completely deleted as this way of checking the selection object is no longer valid.
        * Fix for bug #20910 (https://gna.org/bugs/?20910) - the broken grace.write GUI interface.  The problem was that the Value GUI input element was not detecting list-type data returned by the wiz_combo_iter method.
        * Fix for bug #20915, (https://gna.org/bugs/?20915) - Failure of Grace opening in MS Windows Troels E. Linnet provided this patch, and was discovered during work on a Windows 7 system: telinnet aaattt bio_dot_ku_dot_dk.  This is a small fix for a wrong call to "raise RelaxMissingBinaryError(binary)", when issuing an external call to xmgrace.  The "path_sep" would be equal = [\/], and the RE search would not find(True) the full path specified for the xmgrace file.  This is now shifted to python: os.path.isfile http://docs.python.org/2/library/os.path.html.  Another fix, is that as a standard the command "xmgrace" is provided.  This will work fine through windows cmd, but the true name for program in windows is "xmgrace.exe", and so an additional search for +".exe" is also performed.
        * Fix for the N_state_model.test_absolute_T system test for Mac OS X.  The precision of the check needed to be decreased.
        * Fix for bug #20918 (https://gna.org/bugs/?20918), the hanging of the data pipe editor.  This was reported by Troels Linnet (https://gna.org/users/tlinnet) and is an MS Windows only problem.  The problem is in the wxMSW part of wxPython, and it may be fixed in newer wxPython versions.  The issue is nevertheless now avoided by calling the GUI user function store objects with the arguments wx_wizard_sync=True and wx_wizard_modal=True.  This appears to solve the problem.
        * Decreased the precision of the check in the Frame_order.test_rigid_data_to_rigid_model system test.  This is to allow the test to pass on a MS Windows 7 test machine.
        * More MS Windows fixes, this time a nasty kludge, for the relax system tests.  This is strangely needed for the relax_disp branch and not the trunk for a 64-bit MS Windows 7 test system.  The reason why this WindowsError is triggered by the base tearDown() method in the relax_disp branch and not trunk is a total mystery.  Actually why Windows refuses to complete the file close() operations of the results.write and state.save user functions before calling the tearDown() method is the greater mystery.
        * Bug fix for the batch file permissions for executing Art Palmer's Modelfree4 program.  This was identified in the post http://thread.gmane.org/gmane.science.nmr.relax.devel/3953/focus=4000.  The file was set to be executable, but on Unix systems it would end up with the permissions "---x------".
        * Small comment fix in the sample_scripts/consistency_tests.py script.
        * Fix for the scons fetch_docstrings target.  The user functions need to be explicitly initialised in the fetch_docstrings script as this is not running through relax.
        * Fix for bug #20921 (https://gna.org/bugs/?20921), the GUI tests freezing in MS Windows.  The problem was that the dipolar interaction wizard in the model-free auto-analysis GUI element was calling its user functions asynchronously.  This can lead to racing conditions.  The commit r80084 (http://article.gmane.org/gmane.science.nmr.relax.scm/17840) somehow randomly triggers this racing on MS Windows systems only together with the Mf.test_mf_auto_analysis GUI test.  Now all user functions are called synchronously.
        * Fix for the relax GUI splash screen.  On certain systems, the GUI was failing due to the splash screen.  It is now shown after the main wxPython window has been created.
        * Fix for the new analysis wizard when running the GUI tests.  If the create_button() method is called without a function argument, the wizard is still created.  This is triggered in the relax_disp branch on certain systems.
        * Bug fix for the spin parameter array always being converted to lowercase.  The is in the data_store.mol_res_spin.SpinContainer._back_compat_hook() method.  It always calls the _back_compat_hook_mf_data() method which converts the spin 'params' list all to lowercase.  Now the _back_compat_hook() method first checks that the data pipe is that of a model-free analysis.
        * Proper bug fix for the spin parameter array always being converted to lowercase.  The previous fix was causing failures in certain cases.  One system test and one GUI test were failing.  Now the spin container is checked for the presence 'equation' variable to determine if this is a model free data pipe.
        * Fix for the relax version file for the relax user manual construction.  This was causing 'scons user_manual_pdf' and related targets to fail when a local git repository is used (via git-svn).
        * Bug fix for the page numbers in the index - these were often out by a few pages.  The makeindex command was being run too early in the repetitive LaTeX compilation chain, causing the page numbers to be incorrect.  It is now run twice to fix the problem.
        * Fix for the spectrum.read_intensities user function in the GUI.  The menu string was truncated to spectrum.read.
        * Python 3 fix for the lib.software.nmrpipe.read_list_intensity_seriestab() function.  The inbuilt Python filter() function does not return a list in Python 3, as previously, but rather a filter object.  Therefore a call to list() is required to properly convert the data.
        * An attempt at better handling MS Windows not releasing the file handle on time in the test suite.  The system and unit tests tearDown() method should now be resilient to the strange MS Windows behaviour of not releasing the relax state files.  The tearDown() method should now complete even when this error occurs.  A delay of 3 seconds has been added when the WindowsError occurs to give the OS some time before attempting to delete the file again.  If this fails, then the file deletion operation is skipped.
        * Better handling of temporary file and directory removal in the relax test suite.  The new test_suite.clean_up.deletion() function has been created from the recent method of the same name.  This is used by the tearDown() method of the system, unit, and GUI tests.  It should prevent rare MS Windows errors from appearing due to the OS not releasing a temporary file after a close() call.



Version 2.2.5
(24 March 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/2.2.5

    Features:
        * The files created by the value.write user function now include a header describing the parameter.
        * The relax internal structural object now supports the merger of molecules.  This can be useful if different domains of one system are in two PDB files or are split in the one file.
        * The structure.delete user function can now be used to delete parts of molecules down to the level of individual atoms.
        * Helix and sheet information from PDB files are now stored in the internal structural object as metadata.  The structure.read_pdb and structure.write_pdb user functions will preserve this information.
        * The numbers output by the value.display and value.write user functions can now be scaled.
        * The model-free auto-analysis now generates field strength dependent Rex files for each field present.


    Changes:
        * Added a comment to the output from value.display and value.write to describe the parameter.  This idea is discussed at http://thread.gmane.org/gmane.science.nmr.relax.user/1428.  The idea is to take the parameter description from the specific analysis API and add it to the top of the file or output.  This is to help understand what the Rex value are.  For example for the Rex parameter the first line would be: "# Parameter description:  Chemical exchange relaxation (sigma_ex = Rex / omega**2)."
        * Created the Structure.test_read_merge system test to test a new concept - merging of structures.  The idea is to add the merge argument to the structure.read_pdb user function to allow two different structures in two PDB files to be merged.  This is useful if structures of individual domains have have been solved separately and are located in two PDB files.  Then with the merge flag, you will not need to use and external program or hand edit PDB files to join them.
        * Added the merge flag to the structure.read_pdb user function.  This currently does nothing.
        * The merge flag for the structure.read_pdb user function is now propagated to the pack_structs() method.  This structure API method calls the ModelList.merge_item() method which is yet to be implemented.
        * The MolList.add_item() structural API method now returns the added molecule container.  This is used by the pack_structs() method to alias the molecule, and will be required when structure merging is implemented.
        * Whitespace fixes - replaced many instances of the tab character '\t' with 4 spaces.
        * Implemented the merging of structural objects.  This allows the merge flag of the structure.read_pdb user function to work.
        * The printouts from the structure.read_pdb user function are now different with the merge flag set.  The text now says that the molecules are being merged rather than added.
        * Sections of molecules can now be deleted using the structure.delete user function.  The atom ID argument has been added and this is now propagated into the internal structural object.  This ID string can be used to delete subsets of the 3D structural data in the relax data store.
        * Created the Structure.test_read_write_pdb_1UBQ system test.  This is for checking the use of the structure.delete user function with the atom ID argument.
        * The Structure.test_read_write_pdb_1UBQ system test now checks for HELIX and SHEET records.  This is not implemented yet, but the idea is that the structure.read_pdb and structure.write_pdb should preserve the helix and sheet information present in the original PDB and that the internal structural object should store this information.
        * Created the internal structural object _pdb_chain_id_to_mol_index() method.  This will be used to convert PDB chain IDs, which are used to indicate different molecules in the PDB, into molecule indices for the internal structural object.
        * HELIX PDB records are now read, stored, and written out by the internal structural object.  This affects the structure.read_pdb and structure.write_pdb user functions.  The helix is stored as a metadata type object - its elements do not correspond to the atoms in the structural object.
        * SHEET PDB records are now read, stored, and written out by the internal structural object.  This affects the structure.read_pdb and structure.write_pdb user functions.  The sheet is stored as a metadata type object - its elements do not correspond to the atoms in the structural object.
        * Created 13 unit tests of the Internal._trim_helix() internal structural object method.
        * Added the index_flag argument to all structural API atom_loop() methods.
        * Implemented the internal structural object _trim_helix() method.  This is used when the structure.delete user function is called to trim and remove the helix metadata.  For this to work, the additional method _residue_data() was written to create a dictionary with residue numbers as keys and the residue names as numbers.  This dictionary is used by _trim_helix() to change the residue names in the helix metadata.
        * Created 13 unit tests of the Internal._trim_sheet() internal structural object method.  These are mirror the 13 unit tests of Internal._trim_helix().
        * Implemented the Internal._trim_sheet() internal structural object method.  This is also now used by the structure.delete user function to remove sheet metadata for residues which no longer exist.
        * Modified the ScientificPython structural object atom_loop() method to match the internal object.  If only one element is returned from the atom_loop(), then this is returned as a single item rather than a tuple of length 1.
        * Lots of fixes for the change to the structural API atom_loop() method.  This method when returning a single item now returns a single item rather than a tuple of length 1.
        * The index_flag argument to the ScientificPython structural object atom_loop() method is now used.
        * Created the Structure.test_metadata_xml system test.  This is used to check that the structural metadata (currently helices and sheets) are stored in the relax XML save files and then can be read back into relax again.
        * The helix and sheet metadata is now stored in and read from relax XML state files.
        * Added the scaling argument to the value.display and value.write user functions.  The idea comes from a suggestion by Angelo Figueiredo <am dott figueiredo att fct dott unl dott pt> and was discussed at http://thread.gmane.org/gmane.science.nmr.relax.user/1428/focus=1430.  This allows the user to scale parameters to any value, for example scaling the Rex value to the field strength dependent value.
        * The model-free auto-analysis (the dauvergne_protocol) now generates field strength dependent Rex files.  The idea comes from a suggestion by Angelo Figueiredo <am dott figueiredo att fct dott unl dott pt> and was discussed at http://thread.gmane.org/gmane.science.nmr.relax.user/1428/focus=1430.  One file per field strength is generated and named 'rex_600' for 600 MHz, for example.  The new scaling argument of the value.write user function is being used to scale the tiny field strength independent value used internally in relax to the Rex value in rad.s^-1 that you would see in an R2 data set.
        * Added the new 'comment' argument to the value.write user function.  This is used to add user comments to the top of the file.
        * The model-free auto-analysis (the dauvergne_protocol module) now adds comments to the Rex files.  This is through the new comment argument of the value.write user function.  These comments explain that the Rex values are scaled to the stated field strength.
        * Modified the Mf.test_dauvergne_protocol system test to check for all the files and directories created.
        * Created the new lib.text.sectioning module for formatting titles, subtitles and other sectioning text.  The two functions title() and subtitle() have been implemented.
        * Created unit tests for the title() and subtitle() functions of the lib.text.sectioning module.
        * Expansion of the lib.text.sectioning module.  The following new functions have been added:  box(), section(), subsection(), subsubsection(),subtitle(), subsubtitle(), underline().
        * Expanded the unit testing of the lib.text.sectioning module to cover all title and section functions.
        * Added prespace and postspace arguments to the *section() and *title() functions of lib.text.sectioning.  Through these arguments, the amount of spacing above and below the section text can be controlled.
        * Split the generic_fns.structure.geometric.create_rotor_pdb() function.  The non-relax specific code has been shifted into the rotor_pdb() function.
        * Initialised the lib.structure package - this is currently empty.
        * Shifted the rotor creation components from generic_fns.structure.geometric to lib.structure.rotor.  The create_rotor_pdb() function remains in place as this is the user function backend which checks for data pipes and updates the status object, but the rotor_pdb() and create_rotor_propellers() functions have been moved into the relax library.  The create_rotor_propellers() function has been renamed to lib.structure.rotor.rotor_propellers().
        * Converted links in all docstrings to use the Epydoc hyperlink notation.  This will allow links to be clickable for the API documentation (http://www.nmr-relax.com/api/).
        * Added Epydoc hyperlink markup for the bug tracker in the system test docstring where missing.  This is for a better API documentation (http://www.nmr-relax.com/api/).
        * The lib.structure.rotor.rotor_pdb() rotor_angle argument should now be in radians.  This does not affect the structure.create_rotor_pdb() user function as the generic_fns.structure.geometric.create_rotor_pdb() function converts the value to radians prior to calling the rotor_pdb() function.
        * The lib.structure.rotor.rotor_pdb() function can now handle structural models.  The model number argument has been added to allow the rotor structure to be added to a single model, or to all models if not supplied.


    Bugfixes:
        * Fix for a copy and paste error in the Structure.test_read_merge system test.
        * Fixes for all the Ap4Aase truncated PDB files.  The atom numbers are now sequential, as defined by the PDB standard.
        * Bug fix for the structural data consistency test in the pack_structs() structural API method.  The index was not correct causing failures in certain rare cases.
        * Python 3 fix for an import into the generic_fns.structure.internal module.
        * Python 3 fixes for the relax version information for code checked out from the relax repository.  The subversion version.revision() and version.url() functions now handle the Python 3 issue of Popen working with byte arrays instead of normal strings.



Version 2.2.4
(17 March 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/2.2.4

    Features:
        * Creation of the structure.create_rotor_pdb user function for creating representations of the rotor frame order model.


    Changes:
        * Updated the release checklist document to include the correct instructions for minfx and bmrblib.  These are the packages bundled with relax (http://gna.org/projects/minfx/ and http://gna.org/projects/bmrblib/)
        * Improvements for Python 2 and 3 compatibility.  Much of the Python 2 verses 3 compatibility, as well as different Python 2 version compatibility and different Python 3 version compatibility, code has been shifted into the compat module.  The different parts of relax now import from the compat module for modules/packages with different import semantics for different Python versions.  In addition the different handling of the bz2 and gzip module for reading and writing files has been shifted from 'relax_io' into 'compat'.
        * Updated the 2to3 checklist document to include multiple threads for faster operation.
        * Eliminated the os.devnull import flag dep_check.devnull_import.  This is not needed as the compat relax module defines os.devnull for Python <= 2.3.  The devnull module is no longer part of the relax information printout.
        * Added a more informative error message if the platform module is missing.  This is for Python <= 2.2.  The file from http://hg.python.org/cpython/file/2.3/Lib/platform.py can simply be copied into the lib/pythonX.X/ directory to fix this.
        * Slight change to the message printed if the platform module is missing.
        * Modified the script for running the relax test-suite on multiple Python versions.  The pre-2.2 Python versions are now commented out as well as the abortive Python 3.0.
        * Created the Mf.test_bug_20613_auto_mf_diff_tensor_pdb system test to catch bug #20613.  This was reported by Angelo Miguel Figueiredo <am dott figueiredo att fct dot unl dot pt> at https://gna.org/bugs/?20613.  This test is a direct copy of the Mf.test_bug_20563_missing_ri_error system test.  The only change is that the local tm global model results file (in the local_tm/aic/ directory) has been modified.  This results were read into relax, the file test_suite/shared_data/structures/Ap4Aase_res1-12.pdb loaded into the data pipe, and the results saved again.  This triggers the bug as the problem is the presence of structural data with the local tm global model being selected in the auto-analysis.
        * Shifted all of the model-free specific analysis class documentation variables to the top.  This is simply for better organisation of the code.
        * Created the model-free write_doc class variable talking about the field strength independent Rex value.  This has been added to the value.display and value.write user functions to explain that Rex values are very small and that the user needs to scale them up.
        * Shifted all of the documentation variables to the top of the specific API_base class.  This is for better organisation.
        * Added the write_doc class variable to the specific analysis API class as a empty string.  This is to fix the unit tests.
        * Created the front end for the new structure.create_rotor_pdb user function.  This will be used to create a PDB representation of a rotor motional model.
        * Added file, directory and overwrite force arguments to the structure.create_rotor_pdb user function.
        * Started to implement the backend of the structure.create_rotor_pdb user function.
        * The internal structural object MolContainer.add_atom() method now returns the index of the new atom.
        * Created the internal structural object MolContainer.last_residue() method.
        * Fully implemented the structure.create_rotor_pdb user function.  For this, the generic_fns.structure.geometric.create_rotor_propellers() function was created.


    Bugfixes:
        * Fix for the system tests in the Mac OS X application binary.  The Mf.test_bug_20563_missing_ri_error system test fails in the Mac OS X application binary.  The problem is that the py2app extension used to build the Mac application decides that empty directories are not to be included in the app, so naturally the test fails when checking for these.  Now empty results files have been added to these directories to trick py2app to include them.
        * Fixes for the unit test package __all__ list checking.  Now only *.py files and directories are checked.  In some cases other files could be present in the packages, for example the object files when compiling the C modules.  These would cause the unit tests to fail unnecessarily.
        * Fixes for the unit test __all__ list checking for the lib package for the Mac OS X application.  For some reason the py2app extension which creates the app merges the Python installation directory Resources/lib/python2.7 and the relax lib package into Resources/lib.  Now 'python2.7' is blacklisted when checking the lib package so that the parasitic Python install location is ignored.
        * Bug fix for the structure RMSD function for when old numpy versions are present.  Older numpy versions do not have the ddof argument for the std() standard deviation function,therefore relax now catches this, calculates the biased standard deviation formula, and then multiplies the value by a correction factor to obtain the non-biased estimator.
        * Bug fix for the info relax system information module for when spaces are present in the relax path.  If relax is placed into a directory containing spaces, then the determination of the architecture of the compiled C modules fails.
        * Python 3 fixes for the model-free analysis specific code.  This was causing errors "AttributeError: 'dict_values' object has no attribute 'sort'".
        * Python 3 updates and fixes using the 2to3 program.
        * Bug fix for the external Scientific Python Geometry package.  This is a strange Python 3 issue only triggered when the epydoc Python package is installed.
        * Fix for bug #20613 (https://gna.org/bugs/?20613), the failure of the diffusion tensor PDB creation.  This was reported by Angelo Miguel Figueiredo <am dott figueiredo att fct dot unl dot pt>.  The problem was that the diffusion tensor PDB representation structure.create_diff_tensor_pdb user function was being called even when the local tm global model was selected.  This naturally failed as there is no global diffusion tensor.  Now this user function is avoided for the local tm global model.
        * Fix for the value.write user function for very small parameter values (Rex for example).  This was reported by Martin Ballaschk <ballaschk att fmp-berlin dott de> in the thread http://thread.gmane.org/gmane.science.nmr.relax.user/1397/focus=1402 and by by Angelo Miguel Figueiredo <am dott figueiredo att fct dot unl dot pt> in the unrelated bug report at https://gna.org/bugs/?20613.  The formatting string "20.15f" has been changed to "20.15g" to allow Python to decide if the normal decimal or exponential form of the number should be printed.
        * Fix for a strange and extremely rare typo bug in the model-free specific analysis code.  This was identified by Manish Chaubey <manish dott chaubey att tuebingen dott mpg dott de> in the message at http://thread.gmane.org/gmane.science.nmr.relax.user/1422.  This only occurs if a relaxation data error of zero is encountered and is a bug in the RelaxError message explaining the problem with the data.



Version 2.2.3
(11 March 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/2.2.3

    Features:
        * Added the mol_name_target argument to the structure.load_spins user function.  This allows spins from different molecules to be placed together in the same molecule container in the relax data store.
        * Addition of two new user functions - structure.add_model and structure.rmsd.
        * Created the structure.web_of_motion user function.  This is used to create a special PDB file which represents the atomic motions between different structural models.  Identical atoms of the selected models are concatenated into one model, within a temporary internal structural object, and linked together using PDB CONECT records.
        * Better PDB support in the internal structural object with:  Improvements and fixes in reading/writing, an update of the format to version 3.30, and faster PDB parsing.
        * Creation of two new modules for better PDB support - generic_fns.structure.pdb_read and generic_fns.structure.pdb_write.
        * Improvements to the structure.find_pivot user function including the addition of the func_tol argument to better control the simplex optimisation and the use of the logarithmic barrier function to prevent the pivot from heading to infinity when the solution is a line.
        * Initialised a new package called 'lib' - this will in the future be an extensive collection of functions, methods, classes, objects, etc. useful for the study of all types of molecular dynamics.
        * Line wrapping has been turned on in the relax controller in the GUI so that all text is visible.


    Changes:
        * The relax intro text now includes the repository URL for checked out code.  This is for preserving better debugging and logging information, so that it is clear where the code comes from.
        * Created the Structure.test_load_spins_mol_cat system test.  This will be used to test a new 'mol_name_target' argument to the structure.load_spins user function.
        * Created the Structure.test_delete_multi_pipe system test.  This is to check that the structure.delete user function is operating on a single data pipe.
        * Updated the Freecode instructions in the release checklist document.
        * Created the simple Structure.test_delete_empty system test.  This is to demonstrate a failure of the structure.delete user function when no structural data is present.
        * Added a printout to structure.delete for when no structures are present.
        * Created the Structure.test_rmsd system test.  This test checks the currently unimplemented structure.add_model and structure.rmsd user functions.
        * The structural API num_molecules() method can now handle no data being present.
        * Implemented the structure.add_model user function.
        * Added some more checks to the Structure.test_rmsd system test.
        * Modified the structure.add_model calls in the Structure.test_rmsd system test to include model nums.
        * Added the 'model_num' argument to the structure.add_model user function.
        * Modified the structure.add_atom user function to allow the position argument to be a rank-2 array.  This allows a different coordinate for each model to be specified.
        * Spun out the atomic_rmsd() and calc_mean_structure() functions into their own module.  They were previously in the generic_fns.structure.superimpose module but are now in the new generic_fns.structure.statistics module.
        * Added checks for the atomic information to the Structure.test_rmsd system test.  This demonstrates a failure of structure.add_atom user function when specifying different positions for the different models.
        * Docstring addition for the generic_fns.structure.statistics.atomic_rmsd() function.
        * Implemented the structure.rmsd user function.
        * Fixes for the Structure.test_rmsd system test - it now passes.
        * Created a new float_object argument type which is used by the 'pos' argument of structure.add_atom.  A new arg_check.float_object() function has been created to handle any float object greater than rank-0.
        * Created the Structure.test_rmsd_ubi system test to better check the structure.rmsd user function.  This uses the truncated ubiquitin ensemble in the test suite shared data directories.  The RMSD matches the VMD 1.9.1 output.
        * Added a new module generic_fns.structure.pdb_write for generating the PDB records.  This decouples the formatting code from the internal structural obect.  The PDB format has been updated to version 3.30.  There is one function for each PDB record, allowing this to be easily extended and kept up to date.
        * Created the generic_fns.structure.pdb_read module.  This replaces the internal structural object _parse_pdb_record() method which was handling both ATOM+HETATM and CONECT records.  It should allow greater flexibility in reading data out of other PDB records in the future.  There is one function per PDB record type in this module.
        * Added the full 1UBQ PDB structure to the relax test-suite shared data directories.  This is a small, very quick to read structure which will be used for validating the reading and writing of different PDB record types.
        * Changes to the internal structural object.  The _parse_models_pdb() method has been renamed to _parse_pdb_coord() and the opening of the PDB file shifted into the base load_pdb() method.  This is in preparation for better parsing of PDB files to match the main sections of the PDB format, see http://www.wwpdb.org/documentation/format33/v3.3.html.
        * Created the Structure.test_read_pdb_1UBQ to check the complete parsing of the complex PDB file.  The test is currently quite basic and needs to check more of the internal structural object.
        * Better checks for the atomic data in the Structure.test_read_pdb_1UBQ system test.
        * Added a series of _parse_pdb_*() methods to the internal structural object.  These correspond to each section of the PDB format version 3.30 http://www.wwpdb.org/documentation/format33/v3.3.html.  The currently loop over the records of their section, returning the remaining PDB records.  The aim is for fast parsing and breaking into sections.
        * Faster PDB parsing by the removal of the use of the re.search() function.  Now line slices are directly compared instead.
        * Added some more unit tests for the generic_fns.structure.pdb_read module.  These tests are not yet complete, as it is unknown what these unimplemented functions will return.
        * Completed the unit test of the generic_fns.structure.pdb_read.helix() function.
        * Implemented the generic_fns.structure.pdb_read.helix() function.
        * Created the Mf.test_bug_20531_molmol_macro_write_relaxfault system test.  This is an attempt at catching bug #20531.  It creates all of the m0-m9 and tm0-tm9 models, sets some parameter values, and then attempts to create all of the Molmol macros, PyMOL macros, Grace plots and parameter text files as present in the auto_analysis.dauvergne_protocol module.
        * The spectrometer frequency is now set in the Mf.test_bug_20531_molmol_macro_write_relaxfault system test.  This is needed for the Rex scaling.
        * The spin name, element and isotope is now set in Mf.test_bug_20531_molmol_macro_write_relaxfault.  This is required in this system test so that the marco creation is not skipped.
        * Added some work-arounds for the model-free specific code for when no relaxation data is present.  This is needed for the Rex scaling, as the ID of the first relaxation data set was being used to select the first frequency.  As caught by the Mf.test_bug_20531_molmol_macro_write_relaxfault system test, this fails if no relaxation data is present.
        * Expanded the unit test of the generic_fns.structure.pdb_read.sheet() function.
        * Implemented the PDB SHEET record parsing function generic_fns.structure.pdb_read.sheet().
        * Extended the PDB ATOM record reading unit test to be of 80 characters in length, as per the PDB definition.
        * Created unit tests for the generic_fns.structure.pdb_write module.  This currently covers the atom(), helix() and sheet() functions (the last 2 are not yet implemented).
        * Implemented the PDB HELIX record writing function generic_fns.structure.pdb_write.helix().
        * Improved PDB writing capabilities.  The functions of the generic_fns.structure.pdb_write module now all use the _handle_none() function to avoid the text "None" from appearing in the PDB file and _record_validate() to be sure the record has not been corrupted with bad input causing it to be either less or greater than 80 characters.
        * The Mf.test_bug_20531_molmol_macro_write_relaxfault system test now catches bug #20531.  This now uses the results file attached to the bug report https://gna.org/bugs/?20531.
        * Implemented the PDB SHEET record writing function generic_fns.structure.pdb_write.sheet().
        * Created a unit test for the generic_fns.structure.pdb_write.het() function.
        * Created the generic_fns.structure.pdb_write._handle_text() function.  This private function is used to convert text into PDB suitable format (uppercase and values of None converted to empty strings).
        * The diffusion tensor PDB files are now conform better to the PDB standard.  The HET records are now correct, only capitalised text is present in the files, and trailing whitespace to character 80 has been added.
        * Epydoc docstring formatting for the generic_fns.structure.pdb_write modules.  These large changes improve the API documentation at http://www.nmr-relax.com/api/.
        * Created a unit test for the generic_fns.structure.pdb_write.model() function.
        * Added a new PDB file with 3 models and a few atoms for testing of the structure.web_of_motion user function.
        * Created the Structure.test_web_of_motion_all system test.  This is to check the new structure.web_of_motion user function.
        * The structure.web_of_motion user function can now handle file objects as well as file names as input.
        * Small fixes for the Structure.test_web_of_motion_all system test.
        * Created the Structure.test_web_of_motion_12 system test to show how model sets are currently ignored.
        * Implemented the models argument for the structure.web_of_motion user function.  This was previously not being used and was caught by the Structure.test_web_of_motion_12 system test.
        * Created the Structure.test_web_of_motion_13 system test.  This was just to be sure that the models argument was correctly handled by the structure.web_of_motion user function.
        * The structure.find_pivot user function now accepts the func_tol argument.  This is used to terminate the simplex optimisation when this function tolerance value is reached.
        * Shifted the ensemble pivot finding target function into the maths_fns package.
        * Added a sentence to the README file about the sample_scripts directory.
        * Added a document detailing the possible future layout of relax's packages.
        * The structure.find_pivot user function now uses the logarithmic barrier function.  This is for constrained optimisation and requires the newest minfx code.  The pivot position is constrained within a box of +/- 1000 Angstroms from zero.  This is needed for when the solution is an infinite line - i.e. a rotation axis and not a pivot point.  Previously the simplex optimisation would head toward + or - infinity.  But now with a logarithmic barrier, the simplex algorithm can stabilise and find a point on the axis very quickly, long before reaching the edges of the box.
        * The structure.find_pivot user function now accepts the func_tol and box_limit arguments.  This allows the function tolerance for the simplex optimisation to be specified, as well as the size of the box to constrain the pivot to be within.
        * Initialised the lib.geometry package.  This will be a library of all mathematics functions relating to geometry.
        * Added empty packages to the unit tests for the lib and lib.geometry packages.
        * Updated the maths_fns package __all__ list.
        * Updated the test_suite.unit_tests package __all__ list to be more modern.
        * The n_state_model.number_of_states user function no longer requires the N-state model to be defined.  This was only needed to update the model information, and is skipped if not set.
        * The generic_fns.structure.superimpose.find_centroid() function now prints out Euler angles as well.
        * Large improvements to the checking for all the rdc and pcs user functions.  The new methods check_pipe_setup() have been added to replace all other checking.  This standardises all error checking and provides much better coverage.  The results is that you will be much less likely to encounter a Python traceback when something is forgotten, and will be told via a RelaxError what is missing.
        * The rdc.back_calc and pcs.back_calc user functions now warn if no data was calculated.  This is to inform the user about problems at the place that they occur instead of later on with, for example, the creation of empty data files.
        * Updated the float module to handle numpy floats.  This makes the floatToBinaryString() function compatible with the numpy.float16 type.
        * Removed the prune parameter from the backend of the monte_carlo.error_analysis user function.  This was a dangerous parameter used to mimic the 'Trim' parameter from the Modelfree4 program.  The result is bad statistics.  The probable reason for the 'Trim' parameter was the failure of model-free models in the simulations, but this issue was solved using model elimination (see http://www.nmr-relax.com/refs.html#dAuvergneGooley06).
        * Created the Structure.test_read_xyz_strychnine system test to demonstrate a bug in the XYZ parser.  This is for the reading of XYZ structure files.
        * Created the lib.text package for text manipulation.  The first module will be the text formatting of tables.
        * Created the lib.geometry.lines module for performing geometric operations with lines.  This has one stub of a function lib.geometry.lines.closest_point() which will be used to find the closest point on a line to a given point.
        * Added the package checking unit tests for the lib package.
        * Improved the base class unit test for the package __all__ list.  Subpackages are now also checked.
        * Blacklisted a number of files in the maths_fns package for the package __all__ list unit test.
        * Added a unit test for the lib.geometry package __all__ list.
        * Created a unit test for the lib.geometry.lines.closest_point() function.
        * Created the lib.text.table module.  This originates from the prompt.uf_docstring module as most of that module is functions for creating formatted text tables.
        * Updated the lib package __all__ list for the lib.text package.
        * Implemented the closest_point() and closest_point_ax() functions of lib.geometry.lines.  These two functions do the same thing - find the closest point on a line to any given point - but take different arguments to define the line.
        * Improved the package __all__ list base unit test by skipping all hidden files and directories.
        * Refactored the lib.text.table module.  The create_table() function is now called format_table() and the table_line() function has been made private.  All references to the user function tables and the relax status object have been removed and replaced by arguments to format_table().
        * The prompt.uf_docstring module now uses lib.text.table.format_table().  This significantly simplifies the module.
        * Removed a number of unused imports in prompt.uf_docstring.
        * Deleted prompt.uf_docstring.table_line() as this is now a private function of lib.text.table.
        * Fix for lib.text.table.format_table() as table_line() is now private.
        * Added the spacing argument to lib.text.table.format_table().  This removes the reference to the user function table spacing variable from this function and shifts it to the prompt.uf_docstring.create_table() function.
        * Created the framework for the unit tests of the lib.text package.
        * Created two unit tests for the lib.text.table.format_table() function.
        * Updates to the unit tests of the lib.text.table.format_table() function.
        * Many improvements to the lib.text.table module.  The format_table() function now accepts arguments for text to prefix and postfix to each line,the text padding to the left and right inside the table, and the text used to separate the columns.  The _blank() and _rule() private functions have been added to create distinct table elements.
        * Created the lib.text.table.MULTI_COL constant for defining cells spanning multiple columns.  This is not used yet.
        * Modified the Mf.test_mf_auto_analysis GUI test to catch bug #20603 (https://gna.org/bugs/?20603).
        * Created a unit test for the lib.text.table.format_table() function to test multiple column support.  Support for content spanning multiple cells is yet to be implemented.
        * Implemented multi-column support in lib.text.table.format_table().
        * Spacing between heading rows is now functional in lib.text.table.format_table().
        * Created a new unit test of lib.text.table.format_table() to check for non-string type data.
        * The table contents are now all converted to strings in lib.text.table.format_table().  This uses the _convert_to_string() private function.
        * Converted the test_format_table4() unit test of lib.text.table.format_table() to check justification.  The right justification of cells with numbers will be implemented to match these changes.
        * Numbers are now right justified in cells in the lib.text.table.format_table() function.
        * Modified the test_format_table4() unit test of lib.text.table.format_table().  This change is to test the currently unimplemented custom_format argument.  This will be used to allow special formatting in the table.  For example using '%.3f' for a float.
        * Implemented the custom_format argument for lib.text.table.format_table().  This allows cell contents to be formatted as the user asks.  It defaults to standard string conversion is the custom conversion fails.
        * Rounding error fix for the test_format_table4() unit test of lib.text.table.format_table().
        * Python 3 fix for the test_format_table4() unit test of lib.text.table.format_table().  The string representation of the builtin list object is different in Python 2 vs. 3.
        * Created the test_format_table5() unit test for lib.text.table.format_table().  This test checks what happens if no header is given to format_table().  This currently fails.
        * The lib.text.table.format_table() function can now create a table without headers.
        * Added column number checks for the data input into lib.text.table.format_table().
        * Created the test_format_table6() unit test for lib.text.table.format_table().  This test shows a problem with more than one multi-column cells defined, as well as problems when a multi-column cell is wider than the sum of the widths of the columns it spans.
        * Fix for lib.text.table.format_table() when more than one multi-column cell per row is encountered.  The algorithm for determining the total width of the multi-column cell in _table_line() was not checking if the end of the span was being reached.
        * The lib.text.table.format_table() function now handles overfull multi-column cells.  The _determine_widths() private function has been created to better handle the determination of the table column widths.  It will now extend the width of the last column to allow overfull multi-column cells to fit.
        * Modified the test_format_table5() unit test of lib.text.table.format_table() to check bool types.
        * The lib.text.table.format_table() function now handles boolean types.
        * Booleans are not numbers, so do not right justify them in lib.text.table.format_table().
        * The minfx.__version__ value is now read for the version in the relax information printout.
        * The bmrblib.__version__ value is now read for the version in the relax information printout.
        * All of the specific API data and error returning common methods can now handle missing data/errors.  This affects the _return_data_relax_data() and _return_value_general() methods.
        * Updated the release checklist to include information about updating the FSF directory.
        * Modified the release checklist document to use the stable release tags of minfx and bmrblib.  This is instead of the code in trunk which may not always be in a stable state.
        * Redesign of the generic_fns.mol_res_spin.generate_spin_id() function.  The function now tries to generate a unique ID based on the spin information in the specified data pipe.  This is to attempt to fix a bug uncovered by the Structure.test_read_xyz_internal2 system test.  Defaulting in all cases to the spin name rather than spin number will often fail for a small organic molecule, as the name in XYZ files is the atomic symbol and hence will almost never be unique.
        * Created the generic_fns.mol_res_spin.return_molecule_by_name() function.  This will be used in the future as it is much faster than generic_fns.mol_res_spin.return_molecule()if the molecule name is already known.
        * Missing import affecting the generic_fns.interatomic.create_interatom() function.
        * Reverted the last revision (r18737) as it was not correct and RelaxErrors should be used instead.  The command used was:svn merge -r18737:18736 .
        * Fix for the generic_fns.interatomic.create_interatom() function.  RelaxNoSpinWarning has been replaced with RelaxNoSpinError.
        * Fixes for the metadata update of the residue and spin name and number counts.
        * Created the generic_fns.mol_res_spin.generate_spin_id_unique() function.  This will return a truly unique spin ID string based on the current molecule, residue, and spin data structure.
        * The spin_loop() function now uses generate_spin_id_unique() when the return_id flag is set.  This ensures that the caller received a unique spin ID which can be used to retrieve the corresponding spin container.
        * Improved the generic_fns.mol_res_spin.generate_spin_id_unique() function.  This can now work with molecule, residue, and spin names and numbers alternatively to the containers supplied as arguments.  For this to work, the return_molecule_by_name() function has been improved and the functions return_residue_by_info() and return_spin_by_info() have been added.
        * The pcs.read user function backend now uses generic_fns.mol_res_spin.generate_spin_id_unique().  This allows the matching spin container to always be returned for storing the data.
        * Large speed ups of the Bmrb system tests by the deletion of most of the residues.  On one system, this cuts the time for all 3 Bmrb tests from 70 to ~12 seconds.
        * Added the profile flag keyword argument to the relax startup script for Unix-like systems.  This is to simplify the switching on of profiling.
        * Large cleanup and bugfixes for the molecule, residue, and spin data structure metadata maintenance.  The bugs fixed are important for non-protein molecules.  For example is the spin name is not unique per residue, or per molecule if no residues are defined, many parts of relax would fail.  All of the metadata_*() and spin_id_variants*() functions have been redesigned.  It was also identified that metadata_prune() was being used by different parts of relax for two different purposes - the removal or pruning of metadata prior to the deletion of a data structure and the clean up of no longer valid metadata.  These two goals conflicted resulting in unpredictable behaviour.  Therefore the new metadata_cleanup() and spin_id_variants_cleanup() functions have been created and the two behaviours separated.
        * Fix for the bmrb.read user function for the recent molecule, residue and spin metadata improvements.  The generic_fns.bmrb.generate_sequence() function now calls generic_fns.mol_res_spin.metadata_clean()to be sure that the metadata is correct.  The problem is the structure of the BMRB file with no spin information in the entity record, hence the residues are created first and the spins much later in generate_sequence().
        * Removed unused imports in the generic_fns.rdc module.
        * The generic_fns.mol_res_spin.generate_spin_id_unique() function now handles missing spin containers.  Previously if this function was used to generate a spin ID string of a spin not in the data store,it would fail.  Now it generates an ID by defaulting to generate_spin_id().
        * Converted many calls to generic_fns.mol_res_spin.generate_spin_id() to generate_spin_id_unique().  This will allow many future bugs to be avoided, as the spin ID string is most often used to retrieve spin containers.  By using the generate_spin_id_unique() function, the returning of spin containers will always be correct.
        * Created the Mf.test_bug_20563_missing_ri_error system test to catch bug #20563.  The bug report is at https://gna.org/bugs/?20563.  The data added to the test suite is a highly truncated data set of a analysis completed using the data attached to the bug report.
        * Modified the dauvergne_protocol model-free auto-analysis to aid in debugging.  The write_results_dir argument has been added to allow the test suite to read from one directory in test suite shared data directories and redirect output to a temporary directory.
        * The files from the Mf.test_bug_20563_missing_ri_error system test are now placed in a temporary directory.  This is essential for the test suite to prevent files from going everywhere.
        * The frq.seq user function units argument is no longer read-only.  This is needed for some of the GUI tests in the frame_order_testing branch.


    Bugfixes:
        * Fixes for the structure.delete user function.  This can now handle no data being present, the spin and interatomic data containers are now have their structural data properly deleted, and printouts have been added so the user knows what has happened.
        * Bug fix for the arg_check.is_float_matrix() function for when the dimensions are not given.
        * Fix for the structure.add_atom user function for the internal structural object.  The atomic positions for each model are now correctly set.
        * Formatting fixes for the generic_fns.structure.pdb_write module.
        * Fix for the classic_style() method of the model-free specific Macro class.  This was identified by the new Mf.test_bug_20531_molmol_macro_write_relaxfault system test, but would probably never be encountered by relax users.  It is not related to the bug this test is trying to catch.  The problem is if spins have model-free parameters set up but there is no model-free model initialised - then the Molmol and PyMOL macro creation would fail.
        * Fix for bug #20531 (https://gna.org/bugs/?20531).  This is the bug of the RelaxFault during the final stages of the auto_analysis.dauvergne_protocol model-free analysis when the Molmol and PyMOL macros are being created.  The problem was caused by model m9 (just the Rex parameter) when trying to determine what the order parameter for fast (< 200ps) motions is.  The code was assuming that the model-free model would always contain an order parameter.
        * Fix for the generic_fns.structure.pdb_write.het() function - the record now has trailing whitespace.  The PDB records require trailing whitespace to the 80th character position.
        * Fixes for many of the generic_fns.structure.pdb_write functions.  The PDB records are now all filled with whitespace up to the 80th character.
        * Fix for the creation of HET PDB records in the internal structural object.  The residue name and chain ID were mixed up.
        * Fix for the generic_fns.structure.pdb_write.ter() function.  Whitespace to character 80 is now being added to the TER PDB records.
        * Fix for the creation of the FORMUL PDB records by the internal structural object.  The component number is now set to the index of the hetrogen plus one.  This number should have been a sequential number starting at 1 and is not related to the residue number in any way.
        * Fix for the generic_fns.structure.pdb_write.model() function.  The correct amount of whitespace is now added to the end of the record.
        * Fix for the internal PDB reading - the MASTER record was being marked as a molecule.  Now this record is checked for and the molecule loop terminated.
        * Bug fix for the XYZ 3D structure file reader.  The atom name is now correctly set up for each atom in the file.  The element type setting has also been simplified.
        * Fix for bug 20603 (https://gna.org/bugs/?20603), the relaxation data right click menu failure.  The problem was that there was that the last menu item specified had no contents.  This item has been removed.
        * Fix for bug #20563 (https://gna.org/bugs/?20563), the end failure of the model-free auto-analysis.  This was reported by Stanislava Panova (https://gna.org/users/stacy).  The problem was related to the Monte Carlo simulations.  The generic_fns.monte_carlo.create_data() function is now asking for the errors associated with a certain data point, even if that data point does not exist.  The solution was to check if the relaxation data ID string is present in spin.ri_data_err before accessing the key-value pair (in the specific API _return_error_relax_data() common method).
        * Bug fix for the maintenance of the spin ID lookup table metadata.  This is important for small molecules.  Non-unique IDs were being placed into the lookup table,resulting in incorrect spin containers being sometimes used.  Now the molecule container has the _res_name_count and _res_num_count metadata and the residue container the _spin_name_count and _spin_num_count structures.  These are updated via metadata_update() and are used by the spin_id_variants() function to create a list of purely unique spin IDs.
        * The spin_id argument to the residue.delete user function is no longer read-only.  This allows spin ranges or other complicated IDs to be specified.  This is needed for the Bmrb GUI tests to pass.
        * Fix for the package __all__ list checking unit tests - *.pyc files are now skipped.
        * Fix for one of the RelaxError messages from the SpinList.add_item() method.



Version 2.2.2
(12 February 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/2.2.2

    Features:
        * Improvements to the relax API documentation (http://www.nmr-relax.com/api/).


    Changes:
        * Updated the release checklist to include the devel_scripts/log_converter.py script usage.
        * Modified the relax manual subtitle as this is no longer only for relaxation analysis.
        * Docstring fix for the maths_fns.vectors.random_unit_vector() function (this is for the API documentation at http://www.nmr-relax.com/api/).
        * Epydoc docstring fix for the dfunc_standard() N-state model target function (this is for the API documentation at http://www.nmr-relax.com/api/).
        * Epydoc docstring fixes for the diffusion tensor objects of the relax data store.
        * Added and edited a number of module docstrings.
        * Module and package docstrings additions/improvements for the SCons scripts.
        * Lots of module and package docstring updates for the analysis specific code.
        * Module docstring additions and improvements for the relax data store modules.
        * Addition of the generic_fns package docstring.
        * Added a module docstring for the main relax module.
        * Created the State.test_bug_20480 system test to catch bug #20480, the failure to load a saved relax model-free state in the GUI (https://gna.org/bugs/?20480).  This bug was reported by Stanislava Panova (https://gna.org/users/stacy).
        * Created the Mf.test_bug_20479_gui_final_pipe GUI test to catch bug #20479, the model-free analysis failure in the GUI after setting the protocol mode to local tm. (https://gna.org/bugs/?20479).  This bug was reported by Stanislava Panova (https://gna.org/users/stacy).
        * Added a printout to the GUI test case base check_exceptions() method to explain what is happening.
        * Large expansion of the Mf.test_bug_20479_gui_final_pipe GUI test.  Instead of loading the bug #20480 state file, now the entire GUI analysis starting from scratch and using the relaxation data files is performed remotely by the test.  This is necessary because the result of the bug is present in the state file.
        * Added spherical diffusion to the optimisation in the Mf.test_bug_20479_gui_final_pipe GUI test.
        * Added a global model print out to the Mf.test_bug_20479_gui_final_pipe GUI test.  This is to help identify where failures occur.
        * Proper handling of the dipole interaction wizard in the Mf.test_bug_20479_gui_final_pipe GUI test.  This was causing the subsequent GUI tests to fail as the observer objects from the wizard were not all being unregistered.
        * Added skips for some GUI tests when wxPython version '2.9.4.1 gtk2 (classic)' is used.  There are a number of bugs in this version which cannot be worked around in certain GUI tests, so they must be skipped.
        * More wxPython version '2.9.4.1 gtk2 (classic)' bug avoidances in the GUI tests.  Now the auto-analyses do not check the gauges in the relax controller at the end of the auto NOE, Rx, and model-free analyses, as reading gauge values is faulty in this version.  The Rx test is no longer skipped for this wxPython version.
        * Improved the printout from the align_tensor.matrix_angles user function.  The relax_io.write_data() function is being used and the tensors are now identified by name rather than index.
        * Improved the printouts from the align_tensor.svd user function.
        * The relax program introduction now includes the revision number for subversion checked out copied.  This allows for better identification of the code base being used.
        * Fixes for the Pcs.test_structural_noise system test.  As this is based on random functions, sometimes, though rarely, the test fails.  Now the simulation accuracy has been increased and the tests are less rigorous.
        * Spacing fixes as identified by the Python 2to3 conversion program.


    Bugfixes:
        * Epydoc documentation fix - a circular import in the GUI code paths has been broken.  This affects the API documentation at http://www.nmr-relax.com/api/.
        * Fix for the failed loading of states in the GUI.  This problem was caught by the State.test_bug_20480 GUI test.  If the loading of a state file fails,sometimes the relax data store can contain partial information from that file.  Now if the loading fails in the GUI, relax is reset.
        * Fix for bug #20480, the failure to load a saved relax model-free state in the GUI (https://gna.org/bugs/?20480).  This was reported by Stanislava Panova (https://gna.org/users/stacy).  The problem was that the state file was saved after a RelaxError occurred during the model-free analysis.  The GUI data store information states that the active data pipe is called 'final'.  But an error occurred prior to the 'final' data pipe being created.  The fix was to allow the state to be loaded even if the GUI data store information has been corrupted.
        * Fix for bug #20479 - the failure of non-fully automated model-free analyses in the GUI.  This bug was reported by Stanislava Panova (https://gna.org/users/stacy) at https://gna.org/bugs/?20479.  The problem is GUI specific and was when running each diffusion model one after the other.  The GUI was setting the base data pipe to the 'final' data pipe, which is a clear error.
        * Fix for bug #20481 (https://gna.org/bugs/?20481).  This is the bug where the dauvergne_protocol model-free auto-analysis expects the prolate and oblate spheroids and ellipsoid to be optimised.  It was caught by the Mf.test_bug_20479_gui_final_pipe GUI test.
        * Bug fix for the diffusion tensor PDB creation in the dauvergne_protocol model-free auto-analysis.  The call to the structure.create_diff_tensor_pdb user function now only occurs if structural data is present.



Version 2.2.1
(01 February 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/2.2.1

    Changes:
        * Replaced a reference to freshmeat with Freecode in the Release checklist document.  Freshmeat no longer exists and is now called Freecode (http://freecode.com/projects/nmr-relax).
        * Created the Mf.test_bug_20464_missing_ri_data system test to catch bug #20464.  The data comes from the bug report submitted by Stanislava Panova (stpanova att gmail dot com) at https://gna.org/bugs/?20464.
        * Created the Structure.test_bug_sr_2998_broken_conect_records system test.  This is to catch the bug reported as service request #2998 (https://gna.org/support/?2998) and is for corrupted PDB files with broken CONECT records.
        * Created the Structure.test_bug_20469_scientific_parser_xray_records system test.  This is to catch bug #20469 (https://gna.org/bugs/?20469).
        * Created the Structure.test_bug_20470_alternate_location_indicator system test to catch bug #20470.  This report is at https://gna.org/bugs/?20470.
        * Created the Structure.test_alt_loc_missing system test.  This is to test that the internal relax PDB reader raises an error when a PDB file is encountered with alternate location indicators but the alt_loc argument has not been specified.
        * Created the Bmrb.test_bug_20471_structure_present to catch bug #20471 (https://gna.org/bugs/?20471).
        * Modified the bmrb.read documentation to make it clearer that the data pipe must be empty.


    Bugfixes:
        * Python 3 fix for a print statement in the metal_pos_opt.py N-state model system test script.
        * Python 3 fix for the part of ScientificPython distributed with relax (for the PDB parser).
        * Python 3 import fixes for the GUI.
        * Python 3 fixes for the list sort() method - this has been replaced by the builtin sorted() function.
        * Fix for bug #20464 (https://gna.org/bugs/?20464) - the model-free analysis failure with missing relaxation data.  The problem was the previously missing data had a value of None whereas now the dictionary element can be missing.  Checks have been added to make sure the spin specific relaxation data structures have the key corresponding to the data.
        * Fix for the N_state_model.test_monte_carlo_sims system test.  On certain systems, the chi2 check is too stringent.
        * Fix for the bug reported as the support request #2998 (https://gna.org/support/?2998).  CONECT records pointing to non-existent atoms can now be handled.
        * Fix for bug #20469 (https://gna.org/bugs/?20469).  This is the Failure in reading X-ray PDB files using the ScientificPython parser.  The ScientificPython Geometry.Transformation module is now distributed with relax.  Some linear algebra imports in the Geometry.TensorModule in newly used code paths have been fixed as well.
        * Fix for bug #20470 (https://gna.org/bugs/?20470).  The structure.read_pdb user function now accepts the alt_loc argument for specifying the alternate location indicator to read.  This is used by the internal PDB reader.  The bug was caught by the Structure.test_bug_20470_alternate_location_indicator system test.
        * Fix for bug #20471 (https://gna.org/bugs/?20471) - the is_empty() AttributeError when reading BMRB files.  The problem was that the data pipe is_empty() method was not handling structural data correctly.  The is_empty() method now belongs to the MolContainer objects rather than cdp.structure, and the object cdp.structure is not always present.



Version 2.2.0
(27 January 2013, from /trunk)
http://svn.gna.org/svn/relax/tags/2.2.0

    Features:
        * Implementation of the rdc.copy and pcs.copy user functions.
        * Improved printouts from the model_selection, pipe.display, rdc.read user functions.
        * Implemented the interatomic.copy and interatomic.create user functions
        * Added the 'units' argument to the frq.set user function to allow values other than Hz to be input.
        * Added the 'empty' flag to the sequence.copy user function to allow all the spin contents to be copied.
        * Implemented the pcs.structural_noise user function.  This is used to determine the PCS error due to structural noise via simulation, and adds the error via variance addition to the experimental PCS error.
        * The N-state model grid search optimises each tensor separately when only tensors are optimised.  This massively collapses the grid search size from inc**(5*N) to N*inc**5, where inc are the number of increments per dimension and N is the number of alignments, making a grid search possible.
        * Implemented the rdc.set_errors and pcs.set_errors user functions.
        * Added Monte Carlo simulation support for the paramagnetic centre for PCSs in the N-state model.
        * The paramagnetic centre position for the PCS can now be optimised using algorithms other than simplex, such as BFGS, as the gradients of the PCS equations have been implemented.  This allows for huge speedups as the simplex optimiser is not suited to such a problem.
        * The probabilities and paramagnetic position can now be simultaneously optimised in the N-state model.  Such a combination would have previously failed to unpack the parameters correctly.
        * Constraints are now allowed for the paramagnetic position optimisation in the N-state model.  This is because the gradients are implemented and functional.


    Changes:
        * The relax HTML user manual footer has been modified to remove the name of the person who compiled it.  This is for http://www.nmr-relax.com/manual/index.html, and now contains links for relax (http://www.nmr-relax.com), the manual (http://www.nmr-relax.com/manual) and the PDF version of the manual (http://download.gna.org/relax/manual/relax.pdf).
        * Small syntax fix in the release checklist document.
        * Added the MARC archive links to the development chapter of the relax user manual.  These links are:  http://marc.info/?l=relax-announce&r=1&w=2, http://marc.info/?l=relax-users&r=1&w=2, http://marc.info/?l=relax-devel&r=1&w=2, and http://marc.info/?l=relax-commits&r=1&w=2.
        * The model-free overfit deselection algorithm now fails with a RelaxError when no spins are selected.  This is to avoid situations such as bug #20277 (https://gna.org/bugs/?20277).
        * The pipe.display user function now uses relax_io.write_data() for better output formatting.
        * Created the N_state_model.test_data_copying system test for the rdc.copy and pcs.copy user functions.  These user functions do not exist yet, but this test will be used to implement them.
        * Reactivated the rdc.copy and pcs.copy user function front-ends.  The backends are missing, so relax is currently broken.
        * Created the RelaxNoAlignError error class for use by rdc.copy and pcs.copy.
        * Created the RelaxAlignError error class for use by the rdc.copy and pcs.copy user functions.
        * Implemented the rdc.copy and pcs.copy user function backends.  This code is copied from the relax_data.copy user function and has been tailored to the different data types.
        * Modified the RDC and PCS data copying system test script to check overwriting.  The rdc.copy and pcs.copy user function should support the overwriting of existent values.
        * The rdc.copy and pcs.copy user functions now support overwriting pre-existing data.
        * Removed some debugging printouts.
        * The N_state_model.test_data_copying system test now checks the spin RDC and PCS data.
        * The model_selection user function is now using relax_io.write_data() for its printouts.  This allows for clean formatting when data pipes have long names.
        * The rdc.write and pcs.write user functions now skip deselected spins.
        * The axis for PDB geometric cone can now be turned off in the create_cone_pdb() function.  The axis_flag keyword argument is now accepted and if False will cause the axis to be excluded.  This is useful for the frame order cones for example as its own {x,y,z}-axis system is created.
        * Many docstring fixes for the functions of the generic_fns.structure.geometric module.
        * Created the N_state_model.test_absolute_rdc_menthol system test to demonstrate a pseudo-atom failure.  This is a test of the long range, absolute RDCs for menthol.
        * Added a check for the second Q factor in the N_state_model.test_absolute_rdc_menthol system test.
        * Modified the N_state_model.test_populations system test to catch bug #20335.  This simply adds calls to the rdc.delete and pcs.delete user functions, and then reloads the RDC and PCS data.
        * Modified the temperature user function - the value can be set twice if it is the same value.
        * Modified the frq.set user function - the value can be set twice if it is the same value.
        * The rdc.back_calc user function now handles absolute RDCs.
        * Created the Align_tensor.test_copy system test to catch bug #20338 (https://gna.org/bugs/?20338).
        * The spin.create_pseudo user function 'members' argument is no longer read only in the GUI.  This allows the user to type in shorter spin IDs rather than selecting them from the list.
        * Shifted and renamed the arg_check.check_float() function to check_types.is_float().
        * The relax_io.write_spin_data() function now formats floating point numbers better.  This affects the printouts of many data loading user functions.
        * Better printouts from the rdc.read user function - the numbers are now formatted.
        * Created the interatomic.copy and interatomic.create user functions.  This is simply new front ends for the user for the functions of generic_fns.interatomic.
        * The generic_fns.interatomic.copy() function now accepts spin IDs as arguments to partially copy the data.
        * Expanded the RelaxNoSpinError class to accept the data pipe name for the error printout.
        * Created the Interatomic.test_copy system test to check the interatomic.copy user function.
        * Expanded the Interatomic.test_copy system test to check interatomic.copy without spin IDs.
        * Added a test for the presence of target sequence data in generic_fns.interatomic.copy().
        * Spun out code from generic_fns.pipes.create() into the new check_type() function.  This code will be reused in a new pipe user function.
        * Created the Pipes.test_change_type system test to check the non-existent pipe.change_type user function.
        * Implemented the pipe.change_type user function front and back ends.
        * Created the Align_tensor.test_fix() system test to check the operation of align_tensor.fix.
        * Created some synthetic paramagnetically aligned RDC and PCS data to the test suite.  This will be used in later system tests.
        * Fixes for the PCS values of the paramagnetic alignment test suite data.  The data generation script output and results file have been added to the repository as well.
        * Created the N_state_model.test_paramag_align_fit system test to check the paramagnetic data.  This test check the alignment tensor optimisation of the RDC and PCS data in test_suite/shared_data/align_data/paramagnetic/, loading both alignment data sets but only optimising one tensor.
        * The RelaxErrors when calling user functions in the prompt/script interface are now more informative.  The user function is now stated.  This is to better help the user work out where the problem is.
        * Created the Rdc.test_rdc_copy system test to demonstrate the failure of the rdc.copy user function.
        * Created the Pcs.test_pcs_load and Pcs.test_pcs_copy system tests to check some of the PCS user functions.  The Pcs system test class is new, and these tests check untested areas of relax.
        * Created RelaxInteratomInconsistentError for when the data is inconsistent between two data pipes.
        * Created the generic_fns.interatomic.consistent_interatomic_data() function for checking data consistency.
        * The rdc.copy user function now uses the new consistent_interatomic_data() function prior to copying.  To copy the RDC data, the interatomic data containers must be identical between the two data pipes.
        * Fix for the N_state_model.test_data_copying system test.  The interatomic data is now copied prior to copying the RDC data.
        * Created 4 unit tests to demonstrate the failure of the selection object with spin IDs.
        * The molecule, residue and spin selection object now works with spin IDs.
        * Docstring consistency editing for all parts of the generic_fns.mol_res_spin module.
        * Created the Selection system test class.  This currently has the test Selection.test_deselect_all for checking the deselect.all user function.  The number of tests will be expanded in the future to cover interatomic data containers and the operation of all the select and deselect user functions.
        * Shifted the boolean selection operations of the generic_fns.selection module into two new functions.  These are the boolean_select() and boolean_deselect() functions.  The change removes much duplicated code which could be a source of bugs in the future.
        * The frq.set user function now warns if the frequency is lower than 100 MHz or higher than 2 GHz.
        * Updated the diffusion tensor minimisation sample script as the code is very old and useless.
        * Created the State.test_align_tensor_with_mc_sims system test to catch bug #20414.  The report is at http://gna.org/bugs/?20414.
        * Modified the align_tensor_mc.bz2 save file to catch a strange and rare bug.  This is caught by the State.test_align_tensor_with_mc_sims system test.
        * Spun out the maths_fns.rotation_matrix.random_rot_axis() function into its own module.  The function is now called maths_fns.vectors.random_unit_vector().
        * Added a second data pipe with data to the 'align_tensor_mc.bz2' saved state to catch a bug.  This bug was recently introduced.
        * Added checks for the RDC data in the State.test_align_tensor_with_mc_sims system test.  This is to be sure that the data is properly converted from the old design.
        * Added the 'empty' flag to the sequence.copy user function to allow all the spin contents to be copied.  The user function was only copying the basic empty molecule, residue and spin containers, in contrast to the interatomic.copy user function which copies all of the container contents as well.  This new flag is for backwards compatibility - it allows old scripts to operate as before while enabling the new functionality.
        * Removed the check for the 3D structural data in the paramag.centre user function.  This check is not needed.
        * Created the Pcs.test_structural_noise system test for the new pcs.structural_noise user function.
        * Created the N_state_model.test_mc_sim_failure system test to demonstrate a bug in the N-state model.  This appears to be a problem with Monte Carlo simulations when data is missing.
        * Modified the N_state_model.test_mc_sim_failure system test to include missing PCS data.  This is to catch another bug.
        * Modified the missing data system test script to include Monte Carlo simulations.  This is to cover untested code paths.
        * Added calls to rdc.set_errors and pcs.set_errors in the missing data N-state model system test script.  These user functions currently do not exist, but are needed as the data files contain no errors.
        * Modified all generic_fns.mol_res_spin.get_*() functions to handle no data pipes being present.  These functions were previously raising RelaxErrors as no pipes were present.  They now return empty lists instead.  This allows many of the GUI user functions to open in the GUI when no data is present, allowing better debugging and less confusion for the user.
        * The Pipes.test_change_type system test is skipped if the required scipy module is not installed.
        * Python 3 fix for the new pcs.structural_noise user function.  There was a string/unicode problem in the Grace plot creation code.
        * Created the Pcs.test_load_multi_col_data system test to demonstrate a failure of PCS data loading.  This is a problem when 15N data is in one column and 1H data is in another, and the spin_id argument is used to specify which is which.
        * Added some printouts to the Pcs.test_load_multi_col_data system test.
        * Created the Pcs.test_grace_plot system test to check the pcs.corr_plot user function.
        * Created the Pcs.test_load_multi_col_data2 system test to catch a bug with the molecule name.  This is the same as the Pcs.test_load_multi_col_data system test but the spins have the molecule name set.
        * Created the Mol_res_spin.test_prune_metadata system test to catch a bug in the spin ID lookup table.  Spin IDs appear not to be correctly removed from the lookup table.
        * Added some more checks to the Mol_res_spin.test_prune_metadata system test to demonstrate more bugs.
        * Activated the Monte Carlo simulations in the metal_pos_opt.py system test script.  This is to test the combination of Monte Carlo simulations and paramagnetic centre position optimisation.
        * Added Monte Carlo simulations to the N_state_model.test_paramag_centre_fit system test.  This is to better test the code paths.
        * Modified the N_state_model.test_mc_sim_failure to demonstrate a failure in paramagnetic centre code.  The failure is for the combination of paramagnetic centre optimisation and Monte Carlo simulations.
        * Modified the paramag.centre user function printouts for the 'fix' flag.
        * The alignment tensor objects in the relax data store now support sequential Monte Carlo analyses.  The AlignTensorData.set_sim_num() method was preventing a second Monte Carlo error analysis from being performed by throwing a RelaxError.  The check for previous simulations has been killed.
        * Added checks to the N-state model for the paramagnetic centre optimisation.  Only simplex optimisation without constraints is allowed for the paramagnetic centre position as the PCS gradients and Hessians are not yet implemented for the coordinate parameters.
        * Improved the RDC and PCS Q factor calculation warnings to be more informative.  These warnings sometimes appear at the end of the N-state model optimisation, but it is not clear where they come from.
        * Clean up of some of the logic in N-state model analysis specific code.  The following methods have been added: _opt_tensor(), _opt_uses_align_data(), _opt_uses_pcs(), and _opt_uses_rdc().  These are used through the class to determine what is needed for or used during optimisation,making a lot of checking code more consistent (hence removing latent bugs).
        * Added some more checks to the metal_pos_opt.py N-state model system test script.
        * First attempt at implementing the paramagnetic centre position gradient in the N-state model.  This will be used for faster optimisation of the lanthanide position.  Two new functions have been added:  maths_fns.pcs.ave_pcs_tensor_ddeltaij_dc() and maths_fns.pcs.pcs_constant_grad().  These are used by the dfunc_*() methods of the N-state model target function class.
        * Major code simplification of the N-state model target functions.  The func_tensor_opt(), dfunc_tensor_opt(), and d2func_tensor_opt() methods have been merged with the func_population(), dfunc_population(), and d2func_population() methods into the new func_standard(),dfunc_standard(), and d2func_standard() methods.  This halves the amount of code required to be maintained and debugged.  For the merger, the new probs_fixed class instance variable has been created to determine when the probabilities need to be unpacked from the parameter vector.
        * Removed the unused parameter scaling in the N-state model gradient and Hessian target functions.
        * Added a RelaxError to the N-state model Hessian for the optimisation of the paramagnetic position.  This is because these equations are not derived or coded yet.
        * Expanded the N-state model target function func_standard() docstring to include the xi derivative.  This is the partial derivative with respect to the paramagnetic centre position.
        * Comment fixes in the ave_pcs_tensor_ddeltaij_dc() and pcs_constant_grad() functions.
        * Modified the N-state model metal_pos_opt.py system test script.  This is to test optimisation with the new paramagnetic position gradients.
        * BFGS optimisation is now being used for the N_state_model.test_mc_sim_failure system test.  This is to have better test coverage of the paramagnetic centre position optimisation gradient code paths.
        * Simplified the parameter unpacking in the func_standard() N-state model target function.
        * Improved the comments in the _disassemble_param_vector() N-state model method.
        * Modified the populations.py N-state model system test script to better test optimisation.  The probability of the 2nd state has been slightly shifted to make sure the original value can be found.
        * Modified the metal_pos_opt.py N-state model system test script to demonstrate some failures.
        * Improved the checks of the metal_pos_opt.py N-state model system test script.
        * Modified the metal_pos_opt.py N-state model system test script to catch yet another bug.
        * Added Monte Carlo simulations to the align_fit.py N-state model system test script.  This is to increase the very low coverage of Monte Carlo simulation testing for the N-state model.
        * Modified the metal_pos_opt.py N-state model system test script to test the bootstrapping code path.  This converts the Monte Carlo simulations into bootstrapping to make sure this method also functions correctly.
        * Implemented the N-state model specific return_data() method.  This is needed for bootstrapping.
        * Fixes for the N-state model return_data() method.
        * Modified the RelaxNoRDCError and RelaxNoPCSError to accept no alignment ID.  This is then used to indicate the complete absence of data.
        * Modified the initial testing of the rdc.set_errors and pcs.set_errors user functions.  This is to better indicate to the user what the problem is and why the user function cannot operate.
        * Fixes for the align_fit.py N-state model system test script.  The recently introduced Monte Carlo simulations and associated RDC and PCS error setting was failing when RDC or PCS data was missing.  The script now checks the mode of operation and only sets errors if the corresponding data is present.
        * The N_state_model.test_align_fit system test now checks the simulation PCS values.
        * Fix for the metal_pos_opt.py N-state model system test script.  The moving interatomic data containers are now also deselected.
        * Added extensive data checks to the N_state_model.test_metal_pos_opt system test script.
        * Added new checks in the N_state_model.test_metal_pos_opt system test.  These are for structures which should not be in the deselected spins and interatomic containers
        * The N-state model _check_rdcs() method now skips deselected interatomic data containers.  A FIXME comment has also been added to highlight a possible future problem.
        * Added some consistency to the specific analysis API base class.  The return_data() method argument has been changed from 'spin' to 'data_id', as the data from the base_data_loop() methods are often not spin containers.
        * Made the chi2 value check less stringent in the N_state_model.test_metal_pos_opt system test.  For some bizarre reason, the calc() call in the GUI is less precise.
        * The N_state_model.test_populations system test has been made less stringent to allow MS Windows to pass.


    Bugfixes:
        * Scons fix for MS Windows.  A bug was introduced in the previous version which causes scons to fail on MS Windows.  This has to do with the ctypes.Structure object but strangely led to a AttributeError importing scipy when initialising scons.
        * Another attempt at fixing the scons failure in MS Windows due to scipy and ctypes killing each other.
        * Work around for a numpy bug triggered by scons and the import of Scientific.Visualization.VMD.  For details, see the thread started by Jack Howarth (howarth att bromo dot med dot uc dot edu) started at http://thread.gmane.org/gmane.science.nmr.relax.devel/3663 (Message ID:<20121019140023.GA26861@bromo.med.uc.edu>).
        * Fix for a fatal bug in the multi-processor code (https://gna.org/bugs/?20253).  The Queue module is now imported as 'queue' for Python 3 support, so the code was referring to the wrong object name.
        * Bugfix for the grid_search user function.  The elements of the list of integers can be None to indicate that no grid search in that dimension is to be performed.
        * Fix for model elimination in the modsel.py model-free sample script.  The eliminate user function should be applied to each data pipe separately.
        * Fix for the relax_io.write_data() function - it can now handle no data being sent in.
        * Bugfix for the use of pseudo-atoms for RDCs in the N-state model analysis.  If the second atom of the pair in the intermolecular data container holding the RDC data was a pseudo-atom, then the N-state model optimisation setup would fail.  Now both the first and second atoms being pseudo-atoms is supported.
        * Fix for bug #20335 (https://gna.org/bugs/?20335).  The global alignment ID data structure now has the RDC or PCS ID string correctly removed.
        * Fix for bug #20338 (https://gna.org/bugs/?20338), the new tensor name is now set.
        * Bugfix for the catching of errors in the GUI user functions - the sys module import was missing.
        * Bugfix for the GUI combo_list input element SetValue() method.  Values not belonging to the combo lists can now be set.  This fixes the spin.create_pseudo user function in the test suite, a bug triggered by the N_state_model.test_absolute_rdc_menthol GUI test.
        * Fixes for the align_tensor.copy user function for when the tensor_to argument is not supplied.  Now it is assumed that the new tensor will have the same name as the old.  The new tensor is also properly initialised.
        * Bugfix for the N-state model with PCSs and the temperature or spectrometer frequency are not set.  Previously the missing value was set to 0 K or 1e-10 Hz, but this was causing optimisation to fail.  Now a RelaxError is produced if the value is missing and optimisation is attempted.
        * Fixes for the calculation of RDC and PCS Q factors for when fixed alignment tensors are present.  If a tensor is fixed, then there will be no back-calculated data.  Therefore instead of returning from the function, a continue statement is used to skip just that alignment.
        * Bugfix for the RelaxNoAlignError error class - the printout statement was broken.
        * Bugfix for the rdc.copy user function - it is now functional.  The code was old and untested, and still assumed that the RDC values were held in spin containers rather than the interatomic data containers.
        * Partial fix for bug #20378 (https://gna.org/bugs/index.php?20378).  The gui_raise() function was operating differently under the command line run test suite and the GUI run test suite.  The operation of the function is now consistent, and no RelaxError is raised (unless the raise_flag argument is set).
        * Full fix for bug #20378 (https://gna.org/bugs/index.php?20378).  As no RelaxError is no longer raised in this Bruker.test_bug_20152_read_dc_file GUI test (well only in the command line operation of the GUI tests), instead the current data pipe is checked to make sure no relaxation data was loaded.
        * Fix for bug #20414 (http://gna.org/bugs/?20414).  The variable for the number of simulations in the AlignmentTensorList object is now set prior to setting the simulation parameter values.
        * Fix for bug #20417 (https://gna.org/bugs/?20417).  The backwards compatibility hook for the loading of old relax state and results files can now handle the presence of proton spins.  The data structures are now correctly converted to the current data pipe design.  This is only the case for old files containing PCS data.
        * Fix for bug #20420 (https://gna.org/bugs/?20420).  The problem was in the generic_fns.mol_res_spin.create_spin() function.  The index_molecule() and index_residue() functions where not taking alternative, non-current data pipes into account.
        * Fix for bug #20421 (https://gna.org/bugs/?20421).  The loading of relax state files was only updating the spin ID metadata structures for the current data pipe.  Now all loaded data pipes are updated.
        * RDC data fix for the _back_compat_hook() method for converting old relax state and results files.  The RDC data was not being shifted into the corresponding interatomic data container and remained in the spin containers.
        * Fix for the bug caught by the N_state_model.test_mc_sim_failure system test.  If no RDC error is present, then the returned error from the N-state model analysis specific method return_error() is None.
        * Fix for the missing PCS data in the N-state model Monte Carlo simulations.  This was caught by the N_state_model.test_mc_sim_failure system test.
        * Fix for the N_state_model.test_mc_sim_failure GUI test - the relax data store was not empty at the start.
        * Bugfix for the loading of PCS data from a file with different spin types in different columns.  This was caught by the Pcs.test_load_multi_col_data system test which now passes.
        * Bugfix for generic_fns.mol_res_spin.metadata_prune().  Non-unique molecules and residues are now removed from the spin ID lookup table.
        * Proper bugfix for the spin ID metadata lookup table pruning.  The Mol_res_spin.test_prune_metadata system test now passes.  The previous fix was not complete, and it should have been in the spin_id_variants_elim() function rather than metadata_prune().
        * Python 3 fix for the Pcs.test_grace_plot system test.
        * Fix for the N-state model _minimise_setup_atomic_pos() method for the paramagnetic centre.  The cdp.paramagnetic_centre_sim may not exist prior to Monte Carlo simulations.
        * Fix for the Monte Carlo initialisation of the paramagnetic centre position in the N-state model.  The simulation positions are now initialised to the optimised position.
        * Fix for the N-state model Monte Carlo simulations for when the paramagnetic centre is fixed.
        * Bugfix for the N-state model optimisation of populations and paramagnetic position.  The gradient from dfunc_standard() is now correctly calculated when both are optimised.
        * Fix for the assembly of the N-state model linear constraints.  These were not set up correctly when the populations and paramagnetic position are optimised together.
        * Bugfix for the N-state model Hessian d2func_standard() method.  An index variable name was incorrect causing the population model to fail with Newton optimisation.
        * Bugfixes for the _opt_uses_pcs() and _opt_uses_rdc() N-state model methods.  These now check that the populations are optimised as well.
        * Fix for a bug caught by the N_state_model.test_metal_pos_opt system test.  The problem was that uninitialised probability arrays of None from cdp.probs was always sent into the target function, whereas None should be sent in instead.
        * Big data store clean up fix for the N-state model.  The N-state model specific base_data_loop() method now skips deselected interatomic data containers and spins.  This prevents a lot of junk data being created in the data pipe, for example back calculated and Monte Carlo simulation RDC and PCS data.
        * Fixes for the relaxation curve-fitting specific return_data() method.  Strangely it appears as if this method is never used.



Version 2.1.2
(17 October 2012, from /trunk)
http://svn.gna.org/svn/relax/tags/2.1.2

    Features:
        * Python 2.3 to 3.3 support, including large changes throughout the code to be able to run on Python 3.
        * Improvements to the GUI tutorial in the model-free chapter of the relax manual.
        * A number of bugfixes.
        * Small improvements overall.


    Changes:
        * The scons 'clean' target now removes the Python 3 __pycache__ directories.
        * Small edit to the installation chapter of the user manual.
        * Decreased the Python version dependency from 2.5 to 2.3 in the installation chapter of the user manual.
        * More error checking for the associate_auto() method of the data pipe editor window.
        * Added data pipe bundle error checking for the GUI pipe editor window associate_auto() method.
        * Added some error checking for the data pipe bundle in the auto model-free analysis GUI code.
        * Added some special RelaxErrors for data pipe bundles.
        * Added some bug catching code for the observer objects.  In some rare cases a registered method's key was set to None.  This is now caught and a RelaxError thrown to prevent later indecipherable errors.
        * The setup.py application building script now complains if the Python setuptools are not installed.
        * Updated the relax prompt mode figure in the intro chapter of the user manual to the more modern prompt.
        * Improvements to the API documentation compilation.  The excluded files and directories, as well as hidden ones, are no longer included in the list of files/directories to add to the documentation.
        * Added a file with the relax user functions used for the prompt screenshots.  This is for the manual and the website.
        * Added the public domain LaTeX nth.sty style file for the user manual.  Some LaTeX distributions do not have this style file and, as it is public domain, it can be legally distributed with relax allowing the PDF manual to compile on more systems.
        * Fixes for weird print statements with double brackets generated by the 2to3 Python conversion script.
        * Removed a debugging printout.
        * Python 3 fixes for one of the test data scripts - print statement with function call replacements.
        * Python 3 fixes for non-used Python code - converted print statements to function calls.
        * Python 3 fixes for the script for generating plots of magnetic field lines.
        * Another print statement to function Python 3 fix for the user manual.
        * The Python print statements in the user manual are now function calls to be Python 3 compatible.
        * Python 3 fix for the generic_fns.structure.geometric.angles_regular() function.  Integer divisions no longer produce integers.
        * Better formatting of the test suite summary.
        * The text relax controller log is no longer cleared when a reset occurs.  This allows the test suite results to still be presented in GUI mode.
        * Even cleaner exiting of the GUI - the interpreter thread is terminated by the exit_gui() method.
        * The GUI is now cleanly exited with a call to wx.App.ExitMainLoop rather than wx.Exit.
        * Python 3 fix for the compat module - the Queue2 object needs to always be defined.
        * Added support for Python 2.2 and earlier for the compilation of the C modules.
        * Removed an unused import of the Queue module from the multi-processor.
        * Python 3 fix for the ScientificPython PDB reader unit tests.  The order of the keys returned by a dictionary's keys() method changes randomly in Python 3, so now they are sorted prior to comparison.
        * Redesigned the reset user function backend.  This now no only clears out the relax data store, but it also resets the GUI if present.  Some of the reset code comes from the tearDown() method of the GUI tests.  All windows but the main GUI window are closed and the relax controller gauges are set to zero and the log window text cleared.  These changes should allow GUI tests after an error or failure to pass, something which is currently problematic.
        * Disabled the initial relax intro printout from the GUI when running the test suite.  This prevents the intro text from appearing in the first failed test.
        * Fix for the Mf.test_read_results_1_3_v2_broken() system test for Python 3.2.  The object comparison method no longer converts dictionaries to strings for the comparison, as the string version is different in different Python versions.
        * Fix for the Mf.test_write_results() system test for the Python 3 versions.  The logic for determining Python 3 versions was broken and the incorrect files was used for Python 3.1.
        * Better Python 2.3 support.  The compat module is now imported at the very start to allow the builtins to be set before any other imports.  The sorted() builtin method is now mimicked and the os.devnull string set for Python 2.3 and earlier.
        * Fix for the Mf.test_write_results() system test for Python 3.1.  The XML version in Python 3.1 is the old style.  Therefore the old results file is being used to check this Python 3.1 result.
        * Small improvements to the multiple Python version test suite testing script.
        * Reactivated support for Python 2.3.  This mainly skips the missing 'subprocess' module.  This however decreases relax's functionality a little.
        * Created a special script for testing out relax with Python versions 1.0 all the way to 3.3.  This builds the C modules for each Python version in ~/bin and then runs the test suite, outputting everything to log files.
        * The Results system tests are no longer dependent on the relaxation curve-fitting C modules.  This allows these tests to run when the module cannot be imported.
        * Python 2.5 and lower fix for the test_write_protein_sequence() unit test.  The byte array is wrapped in an eval() statement to allow Python 2.5 and lower to parse the code without failing, and the byte array comparison is now only used for Python 3+.
        * All system and GUI tests reliant on the relax-fit C modules are deactivated if import fails.  This removes a pile of useless error messages from the test suite and presents a table of skipped tests at the end.
        * More Python 3 fixes for the use of now non-existent string module functions.
        * Python 3 fix for the model-free BMRB export - many string module methods no longer exist.
        * Mass conversion of the alignment tensor data structures to the same new design as the diffusion tensor.  This large set of changes matches all of those revisions for the diffusion tensor already committed.  The alignment tensor data structures are now read only, and can only be modified via the set() method.  This is a much simplified design which works on all Python versions.
        * Small clean ups of the diffusion tensor data structure code.
        * Deleted the now unused _update_sim_set() method of the diffusion tensor data structure.
        * Removed the now unused _update_sim_append() method from the diffusion tensor data structure.
        * Cleaned up the docstring of the diffusion tensor data object __setattr__() method.
        * Updated all of the diffusion tensor unit tests to the new design.
        * Fix for the reading of model-free results files from relax 1.2 when simulation data is missing.
        * Fix for the reading of relax 1.2 model-free results files for the diffusion tensor structure redesign.
        * Another fix for the fold_angles() diffusion tensor function - again an incomplete design conversion.
        * Fix for the setting of the diffusion tensor parameter errors in the model-free specific analysis code.
        * Fix for the setup of the model-free Monte Carlo simulations for the new diffusion tensor design.
        * Another fix for the diffusion_tensor.init user function - it was not completely converted.
        * Fix for the fixing of parameters in the model-free analyses.  The diffusion tensor set_fixed() method is now used.
        * Fix for the XML output of the diffusion tensor - only the modifiable parameters are output.  This was the previous behaviour and is needed for the test suite to pass.
        * Converted the palmer.extract user function to use the new diffusion tensor design.
        * The diffusion tensor bmrb_read() function now uses the set_fixed() method instead of fixed().
        * The fix user function now uses the diffusion tensor set_fixed() method.
        * Renamed the diffusion tensor fixed() method to set_fixed() to avoid clashing with the 'fixed' object.
        * Fix for the model-free specific analysis duplicate_data() method for the new design.  The diffusion tensor __mod_attr__ object is now called _mod_attr.
        * Fix for the diffusion tensor to_xml() method for the new design.  For some reason the methods of the Element class are no longer blacklisted.
        * Converted the diffusion tensor data structure from_xml() method to the new tensor design.
        * Fix for the Diffusion_tensor.test_copy system test - the simulation parameters are now read-only.  Instead, the diffusion tensor set() method needs to be called.
        * The setting of list values for the DiffTensorSimList object now works correctly.  The private _set() method now works correctly by calling the base class method, and the normal setting of diffusion tensor simulation values produces a RelaxError.
        * Fix for the diffusion tensor __deepcopy__() replacement method for the new design.
        * The model-free specific analysis _disassemble_param_vector() method now uses the new diffusion tensor design.
        * Modified the setUp() method for the diffusion tensor system tests to use the new design.
        * Redesigned how diffusion tensor simulation structures are handled.  The design is now much cleaner and works with all Python versions.
        * Removed all the unused imports from specific_fns.model_free.main.
        * A number of private diffusion tensor objects and methods have switched to the single leading '_' format.
        * Improvements to the diffusion tensor set() method.  The parameters, errors and simulations are now properly differentiated and stored.
        * Converted the old diffusion tensor __setattr__() method into the set() method.  This is the only way in which diffusion tensor parameters, errors and simulations can be set.
        * Renamed the diffusion tensor data structure type() method to set_type().  This is because the type is stored as the 'type' object, clashing with the method name.
        * Created the diffusion tensor data structure type() method for setting the tensor type.  This is to remove the "cdp.diff_tensor.type = 'x'" code from the core of relax, as the structure is now read only.
        * The new diffusion tensor fixed() method has been created to allow the fixed flag to be changed.
        * Fix for the initialisation of the diffusion tensor data structure, now that it is read-only.
        * The diffusion tensor data structure has been completely converted into a read-only structure.  The __setattr__() method now will always raise a RelaxError, and the diffusion tensor simulation data structure objects __setitem__() method will raise the same error.
        * Updated the relax version numbers and 'trunk' used relax user manual.  For example the information about checking out the main development line was still talking about 1.3 rather than the trunk.
        * Python 3 fix for the setting of diffusion and alignment tensor simulation values.  The previous code somehow worked in Python 2 but was not formally correct and broke in Python 3.
        * Python 3 fix for the model-free results file reading tests.  The ordering of dictionaries is different in Python 3, so now these are properly converted from strings to dictionaries before comparison.  This was not happening because of the XML changes from Python 2.7.3 onwards.
        * The relaxation curve-fitting system tests are now skipped if the module is missing or broken.  This improves the printouts from the test suite and shows a summary of skipped tests rather than a pile of traceback messages and errors.
        * The message about skipping the GUI tests due to wxPython being missing is now more specific.  This was being shown for all runs of the test suite when it only needs to appear if GUI tests have been run.
        * Added a Python 3 version of the truncated OMP model-free results file.  This was created with trunk.
        * Removed the Python 3 byte array hack which should have been removed earlier.
        * The OMP model-free results file generation script now outputs for any relax version.
        * Python 3 fix for the Mf.test_latex_table system test.  The latex_mf_table.py model-free system test script docstring contains backslashes, so the raw string format r"""Text""" is now used.
        * Python 3 support for Modelfree4 and Dasha.  The subprocess.Popen class works with byte arrays rather than strings in Python 3+.  The Python objects are now interconverted when the Python 3 encode() and decode() methods are detected.
        * Removed the pickle format information and arguments from the state user function definitions.
        * Eliminated the State.test_state_pickle() system test as pickled states are no longer supported.
        * Removed the ability to save and restore states using the pickle module.  A pickled state is of no use to relax anymore.  It's removal is needed for Python 3 support.  So now everything defaults to the XML formatted output.
        * Python 3 fix - removed the use of the string module from generic_fns.spectrum.
        * Python 3 fix for the relax_io.open_write_file() function.  This now matches the behaviour of open_read_file() in that there are three different behaviours for opening bz2 and gz files for writing to for the different Python versions (one for Python 2, one for Python 3.0 to 3.2, and one for Python 3.3+).  All byte streams have been eliminated as open_write_file() is for creating text files.
        * Python 3 fix for the Noe.test_noe_analysis() system test for the grace.write precision changes.
        * For consistency between Python 2 and 3, the grace.write user function outputs to 15 decimal places.  This increased precision will only be of use in the relax test suite.
        * Python 3 fix for the Pipes.test_pipe_bundle() system test.  The order of bundle names returned by generic_fns.pipes.bundle_names() is not guaranteed in Python 3.
        * The C module compilation testing script now accepts the Python version as a first argument.
        * The relax_io.open_read_file() now supports all Python versions over 2.4.  This required some really nasty hacks for Python 3.0, 3.1 and 3.2 with the Bzip2Fixed and GzipFixed classes overriding the incomplete and buggy bz2.BZ2File and gzip.GzipFile modules, and being wrapped around io.TextIOWrapper().
        * Added the IO module to the relax information printout and dependency checks.
        * The manual C module compilation script is now executable.
        * Renamed the 'scripts' directory to 'devel_scripts' so that users are less likely to ask about the scripts.
        * Finished off the C module compilation testing script.
        * Added a script for testing out the C module compilation on multiple Python targets.
        * The relax_fit specific analysis module now supports both Python 2 and 3.
        * The relaxation curve-fitting C module now supports compilation on both Python 2 and 3.
        * Created the simple Sequence.test_sequence_copy() system test to catch bug #20213 (https://gna.org/bugs/?20213).
        * The Mf.test_bug_20213_asn_sidechain() system test now uses a temporary directory for output.
        * Added the Mf.test_bug_20213_asn_sidechain() system test to catch bug #20213.  The data and script comes from the files 'sh3-47.2.zip' and 'run.py' attached to the bug report https://gna.org/bugs/?20213.  The PDB now only contains Asp47, the optimisation parameters have been made almost insignificant, and all models but 'tm0' have been removed from the analysis.
        * The Python 3 dictionary values() method no longer returns a list, so a list() call is needed.
        * Python 3 bug fix for the geometric structure module - another integer division to float problem.
        * The Mf.test_write_results system test can now select the correct file to compare against in Python 3.  The algorithm for determining if the 'final_results_trunc_1.3_v2' or 'final_results_trunc_1.3_pre_py2.7.3_v2' file should be used could not handle Python 3.
        * Python 3 fix for the format detection of results and save files.
        * Python 3 import fixes for the generic_fns.structure package using relative paths.
        * Python 3 fix - removed the use of the string.lower() function in the OpenDX mapping code.
        * Python 3 fix for the frame order system tests.  As float to string conversions behave differently, the %.1f formatting is used to force only a single decimal place float.
        * Python 3 fix for the frame order system tests - float to string conversions behave differently.  Now the explicit %.1f formatting is used to force only a single decimal place float.
        * Python 3 integer division to float fix for the frame order analysis.
        * Python 3 bug fix for the frame order analysis - another int division problem.
        * Python 3 fixes - eliminated all usage of the dictionary has_key() calls as they are no longer present.
        * Python 2 and 3 support in the generic_fns.relax_data module using 2to3.  One print call was fixed after running 2to3.
        * Python 3 bug fix for the Structure.test_read_pdb_mol_2_model_scientific system tests.  This is again an integer division problem returning a float.
        * Python 3 fix for the test_write_protein_sequence() unit test.  This is again a string verses byte verses unicode problem.
        * Python 3 fix for the user function docstring creation in the prompt UI mode.  Again this is the problem of a division now returning a float rather than an int.
        * Python 3 bug fix for the N-state model target function setup.  The num_tensors variable needs to be an integer, but the Python 3 division will create a float type.
        * Python 3 fix for the results.read user function matching that of state.load.
        * Python 3 bug fix for the relax_io.read_spin_data() function.  The built in max() function cannot handle the value of None, therefore the filter() function is used to remove all instances of None from the list.
        * Python 3 bug fix for the state.load user function.  The header line of pickled states (rather than the standard XML states) is of the b'' byte format.  This is now converted to a string, and the search expression is comparing it to the raw string r"<\?xml".
        * Better support for both Python 2 and 3 in the relax data store.  The 2to3 script was used on all of the files in the data package.
        * Python 3 preparation - the relax data store (the data package) now supports both Python 2 and 3.
        * Python 3 fix - the relax_errors.AllRelaxErrors object is now a proper tuple.  Due to bad coding, it was previously a nested tuple.  This nested tuple worked in Python 2, but is fatal for Python 3.
        * Python 3 fixes - the character '\' is now properly escaped as '\\' in the stereochemistry auto-analysis.
        * Fix for the test suite summary for Python 3.  The test suite now runs, but fails miserably, under Python 3.
        * Fix for the running of the test suite under Python 3.  The zip() function used in the loadTestsFromTestCase() function is now an iterator, so it needs to be passed through the list() function to generate a list.
        * Fix for the test_parse_token_multi_element_name() unit test, as parse_token() no longer sorts.
        * Python 3 fix for the generic_fns.mol_res_spin.parse_token() function.  Mixed lists for int and string can no longer be sorted.  This sort call is not needed anyway.
        * Automatically converted the generic_fns.mol_res_spin module to support both Python 2 and 3.
        * For running relax with Python 2, the __builtin__.range() function has been replaced with xrange.  This causes large speed ups (speed that was lost with the earlier xrange() to range() conversions), and memory decreases.  For example on one system, the system test time decreased from 513.029s to 487.586s.
        * The compat module now has the py_version variable specifying if this is Python 2 or 3.
        * Import fix for the OpenDX mapping package, recently broken with the relative import for Python 3 change.
        * More usage of the is_unicode() function in the generic_fns.mol_res_spin module.
        * Created the check_types.is_unicode() function for Python 2+3 compatibility.  This is used in the generic_fns.mol_res_spin module.
        * Another raise() function call to statement change for 2to3 preparations.
        * Converted some raise() function calls to raise statements in preparation for the 2to3 conversion.
        * Converted the ScientificPython PDB reader to support both Python 2 and 3.  The __repr__() method was manually modified due to the 'list' variable clashing with the 'list'type.
        * Created a new module for simultaneous Python 2 and 3 support in relax called 'compat'.
        * Python 3 fixes - the list() function is now used in combination with range() to generate the ordered list.  range() in Python 3 is an iterator object (just as xrange was), so now the list() function has to be called.
        * Python 3 preparations - mass conversion of all xrange() calls to range().
        * Created the special check_types.is_filetype() function for checking for files in all Python versions.
        * Python 3 - eliminated an unneeded xrange call.
        * Python 3 - eliminated the use of the map() function, as this behaves differently in Python 3.
        * Python 3 - removed the use of the string.lower() function as it is missing in Python 3.
        * Python 3 fix for the relax information printout.  The try blocks seem to now operate slightly differently in Python 3.
        * Python 2 fixes - the Python 3 fixes for the ScientificPython module imports broke Python 2.
        * Python 3 - the cStringIO.StringIO import switches to io.StringIO if missing.
        * Python 3 - relative module paths are now used for the test suite runner.
        * Python 3 fixes for the version module for catching empty lists.
        * Python 3 fix - ensure an integer is actually an integer (division now converts ints to floats).
        * Python 3 - fixes for the renaming of the Queue package.
        * Python 3 - converted the last of the except error catching statements to be Python 2.4+ compatible.
        * Python 3 - removal of the use of the string.atoi and string.atof functions.  These have been depreciated since Python 2.0!  They have been replace by the int and float functions.
        * Python 3 - a number of fixes for running the ScientificPython modules in relax on Python 2 and 3.  This includes relative imports, converting raise statements to function calls, removal of the use of many string module functions which do not exist in Python 3, etc.
        * Python 3 - modified some except statements to be Python 2.4+ compatible in a ScientificPython module.
        * Python 3 - converted some print statements to function calls in the ScientificPython modules.
        * Python 3 - fix for an os.chmod() call by using the stat module rather than the number 0775.  The number 0755 is no longer valid in Python 3.
        * Python 3 - a pile of relative path fixes for many relax modules.
        * Python 3 - removed the use of the types module from generic_fns.sequence.  The relax arg_check module is now being used instead.
        * Python 3 preparations - removed all of the string module functions which no longer exist in Python 3.  These functions are part of the strings themselves now.
        * Improvements for the relax test suite synopsis for when the wxPython module is missing or broken.  This is simply a printout improvement.
        * Python 3 preparations - removal of some unneeded xrange() calls.
        * Python 3 preparations - the data package now really does use the absolute path for its module imports.
        * Python 3 preparations - the data package now uses absolute imports for all its modules.
        * Python 3 preparations - eliminated the use of the types.ListType object.
        * Python 3 preparations - absolute module path fixes.
        * Python 3 preparations - support for both Python 2 __builtin__ and Python 3 builtins modules.

        * Some changes in preparation for Python 3.
        * Removed the 'force flag' text from the RelaxWarning messages output by the bruker.read user function.  The force flag arguments of the generic_fns.mol_res_spin.name_spin() and generic_fns.mol_res_spin.set_spin_isotope() functions can now be set to None to suppress the text.
        * Fixes for the checks in the Mf.test_mf_auto_analysis() GUI test for the recent test suite data changes.
        * The CSA setting in the model-free auto GUI analysis now defaults to the '@N*' spin ID.  Previously no spin ID was being used so that the protons where also having their CSA values set to that of the nitrogens.  Now the execution checking code skips the proton CSA check.
        * Added star versions of the standard spin IDs to the spin ID GUI element (e.g. '@N*', '@H*').
        * Fix for the comment on the 'Export' button in the BMRB export window.
        * Lots of editing of the model-free GUI section of the user manual.
        * Fix for the Relax_data.test_delete system test for the changes to the relax_data.read user function.
        * Fix for the Relax_data.test_read unit tests for the relax_data.read user function changes.
        * Fix to the Dasha system test needed for the changes to the relax_data.read user function.
        * Fix for the N_state_model.test_monte_carlo_sims due to the changed sphere.pdb test suite file.
        * Relaxation data is no longer loaded by relax_data.read if the values and errors are both None.
        * Modified the Mf.test_dauvergne_protocol system test to catch bug #20197 (https://gna.org/bugs/?20197).  The sphere test data NE1 and HE1 data is now being used in this system test, triggering the bug.
        * Small change to the sphere model model-free test suite data.  The trptophan indole data is now merged into the last residue (a glycine) to catch bug #20197 (https://gna.org/bugs/?20197).
        * The overfit_deselect() printouts for all specific analyses are now regularised and match the model-free printouts.
        * All overfit_deselect() methods now accept and use the verbose argument.
        * Printouts for the over-fitting deselection of spins are suppressed for the back-calculation of relaxation data.  This affects the model-free Monte Carlo simulations, improving the output.
        * More improvements to the model-free over-fitting deselection printouts.
        * Improved the model-free overfitting deselection printouts prior to optimisation.  Only a single message per spin is now given when the spin is deselected, minimising the amount of output.
        * Added a tryptophan NE1 data set to the sphere model-free model test data.  This is in preparation to catch bug #20197 (https://gna.org/bugs/?20197).  The scripts have also been updated for the newer relax designs.
        * Added the data_check Boolean argument to all of the specific analysis overfit_deselect() methods.  This allows the unit tests to pass.


    Bugfixes:
        * Fix for the State.test_load_state_no_gui() GUI test - the data pipe bundle is now given.
        * Another attempt at fixing a nasty circular import in the relax GUI.
        * Fix for the relax user manual compilation.  The full path for an icon in the graphics directory was being used.
        * API documentation fix - a circular import has been broken.  This was only a circular import when the gui package is imported from an external program like Epydoc.
        * PDB format fix for the atom numbers of zero - the atom number should be consecutive and unique.
        * Big fixes for the running of the GUI tests.  The GUI initialisation and termination, when not running in GUI mode, is now preformed outside of the Python unittest framework.  The GUI was previously initialised in the setUp() method for all GUI tests, but for some reason this caused abrupt terminations of the GUI_test_runner.run() method.  This run method, when finished, would not return to the Test_suite_runner but would cause the Python interpreter to silently die.  The result was that the test suite summary would appear not to be printed out.
        * Python 2.3 and earlier fix for the unit test module for the float module.  The 'tests' class variable was renamed so that the test suite does not think that it is a unit test.
        * Bug fix for the unit test runner - this restores functionality broken all the way back at r12100.  The TEST_SUITE_ROOT constant no longer exists, so the check for it is now skipped.  This allows tests to be run directly by the script.
        * Python 2.4 and earlier fixes for the Queuing module.  The TaskQueue class from http://code.activestate.com/recipes/475160/ which was added to Python 2.5+ has been added to the compat module.  This module is now used for all imports of the Queue class for all Python versions.
        * Test suite bug fix - the GUI tests now cleanly terminate the interpreter thread.  This allows the test suite to terminate normally.  With different Python versions on different operating systems, this could sometimes cause the test suite to freeze at the end, the final printout to be missing, or other strange behaviour.
        * Python 2.3- fixes - the Modelfree4 and Dasha system tests are now skipped if the subprocess module is missing.
        * Python 2.3 and earlier fix for the Test_relax_re.test_search() unit test.  The unittest assertTrue() and assertFalse() methods do not exist, so assertEqual() is used instead.
        * Python 2.3 and earlier fix - the subprocess module is only imported when present.  This is for the stereochem_analysis auto-analysis, but the import kills all of the auto-analyses.
        * Python 2.3 fix - eliminated the superfluous operator.itemgetter() call in the diffusion tensor code.
        * Python 2.4 and earlier fix for the GUI.  Try-except-finally statement blocks are not supported, so these have to nested in two try statements.
        * Python 2.4 fix - the unit test runner no longer uses the builtin set() method.
        * Python 2.4 and lower fix for the pipe_loop() generator method.  In these Python versions, a 'try' block with a 'finally' statement cannot contain 'yield' statements.  This work around should be compatible with all Python versions.
        * Python 2.4 fixes - the ctypes module does not exist in Python versions 2.4 and lower.  This is only used for some non-essential functionality on MS Windows, so now it is deactivated if not present.
        * Fix for bug #20213 (https://gna.org/bugs/?20213).  The problem was that the generic_fns.sequence.generate() function was searching for a spin based on its spin ID generated from the spin name and not spin number.  Hence two spins with the same name but different numbers were treated as the same spin, and only data from one was being generated via the copy() function.
        * Bug fix for wxPython 2.9.4.0 - the unsetting of the alpha mask for all bitmap images should now work.  The wx.Bitmap.SetMaskColour(None) call does not work, so instead a wx.Colour() instance is passed in instead.
        * Fix for bug #20210 (https://gna.org/bugs/?20210) - relax now runs again without having wxPython installed.
        * Bug fix for the BMRB system test initialisation for when the bmrblib module is missing.  The base __init__() method needs to be initialised first.
        * Fix for bug #20201 (https://gna.org/bugs/?20201).  The bruker.read user function can now handle the situation where multiple spins per residue are already loaded prior to the user function call.  The isotope value from the DC file is now translated to the element name and this is used as part of the spin ID string.
        * Fix for bug #20197 (https://gna.org/bugs/?20197) - the PyMOL and Molmol macro failure.  The macro creation now only operates on spins called 'N' and assumes these are the backbone nitrogens.  The sidechain tryptophan indole NH data will need to be detected and added later.
        * Fix for bug #20198 (https://gna.org/bugs/?20198) - the relaxation data back-calculation error.  The problem was that the call to the model-free overfit_deselect() method was deselecting any spins lacking relaxation data.  This should not happen, as no spins need to have relaxation data for this calculation.



Version 2.1.1
(21 September 2012, from /trunk)
http://svn.gna.org/svn/relax/tags/2.1.1

    Features:
        * Creation of extensive tutorials for both the script and GUI modes for the NOE, R1 and R2, model-free chapters with screenshots in of the GUI in operation.
        * Restored support for multiple spin types in the NOE, R1 and R2 analyses allowing, for example, tryptophan sidechain indole NE1 data to be analysed.
        * The activation and expansion of the consistency testing chapter to the user manual.
        * The completion of the reduced spectral density mapping chapter of the user manual.
        * Improvements to the user function section of the user manual with better visual separation and the inclusion of the icons used in the GUI.
        * Creation of the relax data model chapter of the user manual to explain how to set up data in relax in all UI modes (with screenshots in the GUI mode).
        * Creation of the citations chapter of the user manual to help users properly cite the parts of relax that they use.
        * A complete rewrite of the relaxation curve-fitting chapter of the relax manual.
        * General improvements and expansions throughout the user manual (the manual is now 15 Mb compared to 4.3 Mb for relax 2.1.0).


    Changes:
        * Modified the model-free optimisation final printout to be more multi-processor friendly.  The message saying that the optimised chi2 is an improvement or not now includes the spin ID string if present.  This is more informative for the multi-processor mpi4py printouts.
        * Added the use of the program 'nice' to the model-free GUI tutorial in the user manual.
        * Removed the out of date and useless README file for the HTML version of the user manual.
        * Added a BMRB section to the end of the model-free chapter of the user manual.
        * Massive expansion of the model-free chapter of the user manual including script and GUI tutorials.  The model-free chapter now has step-by-step tutorials for both the prompt/script mode and GUI mode for the new automated model-free protocol (the d'Auvergne protocol).  This includes a large set of screenshots for the GUI mode.
        * Created the User_functions.test_value_set GUI test demonstrating the failure of the value.set user function.
        * Modified the dauvergne_protocol sample script to handle tryptophan indole NE1 data.
        * The graphics.fetch_icon() function argument 'format' can now be set to None.  This will return the file path without the extension.
        * Improvements to the duplicate user manual title finding script.
        * Created a simple shell script to find duplicate titles in the relax user manual.  This is important for the HTML version of the manual as duplicated titles causes HTML pages to be overwritten.  For example all chapters, sections and subsections titled "Introduction" will load the introduction.html file which will contain the text of the last section with that title!
        * Additions to the scripting section of the relaxation curve-fitting chapter of the user manual.
        * A small edit to the intro chapter for the multi-processor operation and logging.
        * Added some labelling to the infrastructure chapter of the user manual for referencing.
        * A number of updates and edits to the intro chapter of the user manual.  The model-free GUI screenshot has been shifted to the intro chapter in preparation for a full tutorial with screenshots in the model-free chapter.
        * Updated the data model chapter of the user manual to cover the handling of protons.  This change includes the modification of the PDB reading screenshot to demonstrate the reading of a specific model and the naming of the molecule.
        * All of the GUI strings and text are now formatted with a small sans serif font in the user manual.  This is because in the GUI, a sans serif font is almost always used be default.
        * Modified the User_functions.test_structure_pdb_read() GUI test to catch another bug.  This is a bug recently introduced with the fixes to the other sequence editor GUI window problems.
        * Created the User_functions.test_structure_pdb_read GUI test for checking the sequence editor window.  This new user function GUI testing class is to be used for testing out the special GUI elements not invoked within the unit testing.  The test_structure_pdb_read() test specifically shows a number of failures of the sequence editor window.
        * Modified the operation of the sequence GUI element to have access to the sequence editor window.  This is to allow this GUI element to be blasted within the test suite.
        * Improvements to the descriptions of the structure.read_xyz user function arguments.
        * Improvements to the descriptions of the structure.read_pdb user function arguments.
        * Added @HE1 to the spin ID list of the structure.load_spins user function.  This is only seen in the GUI.
        * Created the new generic_fns.result_files for standardising the handling of results files.  This fixes the bug where results files are repetitively added to the list.  All of the code touching cdp.result_files now uses this module instead.
        * Updated the scripting section of the intro chapter of the user manual for non-technical users.
        * Expanded the spin ID list for the structure.load_spins user function.  This now includes the spins "@N", "@NE1", "@C", "@H", "@O", "@P", ":A@C2", ":A@C8", ":G@N1",":G@C8", ":C@C5", ":C@C5", ":U@N3", ":U@C5", ":U@C6".
        * Changed the RelaxError for missing relaxation times in the relaxation curve-fitting analyses.
        * Modified the test_bug_20152_read_dc_file() GUI test to catch the RelaxError.  This error is because of the old PDC format.
        * Created the test_bug_20152_read_dc_file() GUI test for catching bug #20152 (https://gna.org/bugs/?20152).  This includes truncated data taken from the bug report (with data for only the first 3 residues).
        * Set up the Bruker Dynamics Center system tests as GUI tests.  This is in preparation for catching bug #20152 (https://gna.org/bugs/?20152).
        * Re-added Dominique Marion's solvent suppression to the NMRPipe script in the curve-fitting chapter.
        * A few small edits of the relaxation curve-fitting chapter.  This is to reinforce the exact time of the relaxation time period.
        * Added some text to explain why test only J(0) is discussed whereas the script also calculated F_R2 and F_eta.  This was suggested by Edward d'Auvergne in a post at:https://mail.gna.org/public/relax-devel/2012-09/msg00044.html.
        * Big clean up of the Bibtex bibliography file for the relax user manual.
        * Small edits of the consistency testing figure caption in the relax user manual.
        * Editing and a number of fixes/cleanups for the consistency testing chapter of the user manual.
        * Editing of the "Values, gradients, and Hessians" chapter of the user manual to make it fit better.  The context of this chapter has been specified by changing the title to "Optimisation of relaxation data -- values, gradients, and Hessians" and the intro text has been updated.  As this chapter is no longer straight after the model-free chapter, this is needed.
        * Made a small correction to a reference such that a superscript is correctly displayed.
        * Added the bounding box and a centerline command to the code for the figure for consistency testing.  This follows two remarks by Edward d'Auvergne at https://mail.gna.org/public/relax-devel/2012-09/msg00030.html and https://mail.gna.org/public/relax-devel/2012-09/msg00032.html.
        * Added more text to describe the consistency testing approach.  Also includes a very basic point by point protocol for consistency testing.  This was proposed by by Edward d'Auvergne at https://mail.gna.org/public/relax-devel/2012-09/msg00028.html.  This also follows a discussion started by Edward d'Auvergne at https://mail.gna.org/public/relax-devel/2012-09/msg00019.html.
        * Added some text to describe the consistency testing example figure.  This follows a discussion started by Edward d'Auvergne at https://mail.gna.org/public/relax-devel/2012-09/msg00019.html.
        * Added a modified version of Figure 1 from Morin and Gagne (JBNMR, 2009 (http://dx.doi.org/10.1007/s10858-009-9381-4)).  File formats are .agr (xmgrace), eps (gzipped), and png.  This follows a discussion started by Edward d'Auvergne at https://mail.gna.org/public/relax-devel/2012-09/msg00019.html.
        * Added a directory for placing consistency testing graphics.  This follows a discussion started by Edward d'Auvergne at https://mail.gna.org/public/relax-devel/2012-09/msg00019.html.
        * Corrected the bibliography entries whih were still in plain text and not as a Latex \cite call.  Also renamed the MorinGagne09 entry to MorinGagne09a as there is now also MorinGagne09b.  This was proposed by Edward d'Auvergne in a post at https://mail.gna.org/public/relax-devel/2012-09/msg00025.html.
        * Added the DOI to reference Morin11 and fixed indentation (10.1016/j.pnmrs.2010.12.003).  This follows a comment by Edward d'Auvergne at https://mail.gna.org/public/relax-devel/2012-09/msg00022.html.
        * Deletion of the relax version LaTeX file - this is automatically created anyway.
        * Added text to detail the usage of the consistency testing script.  This text was modified from the corresponding text for jw_mapping.  This follows a discussion started by Edward d'Auvergne at https://mail.gna.org/public/relax-devel/2012-09/msg00019.html.
        * Added some text and a reference to the consistency testing chapter.  This follows a discussion started by Edward d'Auvergne at https://mail.gna.org/public/relax-devel/2012-09/msg00019.html.
        * Editing of the nmrPipe script in the Rx curve-fitting chapter of the manual.
        * Some editing of the NOE chapter of the relax user manual.
        * The old R1 and R2 analysis screenshots have been shifted to the intro chapter.
        * Editing of the relax data model chapter of the user manual.
        * Large expansion and lots of editing of the relaxation curve-fitting chapter of the user manual.  The GUI section has been added which includes step-by-step instructions on how to use relax,illustrated with screenshots at each step.  There has been general editing of the whole of the chapter as well.
        * Added a tonne of GUI screenshots of an R1 analysis.  These will be used in the relaxation curve-fitting chapter of the user manual.
        * Added some Grace plots from an NOE analysis for use in the user manual.
        * Small edits of the relax data model chapter of the user manual.
        * Editing of the relaxation curve-fitting and NOE chapters of the user manual.  This is to synchronise the format of the two chapters, and includes the swapping of text between them.
        * Added trp indole NH loading into the relaxation curve-fitting sample script.
        * Large edits of the consistency testing chapter of the user manual.
        * Activated the consistency testing chapter of the user manual.
        * Added a LaTeX label to the J(w) mapping chapter.
        * Added the other consistency testing references to the citation chapter of the manual.
        * Added the Fushman et al., 1998 reference.
        * Fix for the Farrow et al., 1995 DOI number.
        * Changed the order of the Rx curve-fitting and NOE chapters in the relax manual.  This is because the NOE chapter references passages from the Rx curve-fitting chapter, so it's more logical to have the Rx curve-fitting chapter first.
        * Clean up of a paragraph of the data model chapter of the user manual.
        * Improved the consistency in the user manual by using the new LaTeX commands.  These changes are throughout the manual and affect all the text of user functions, menu items, prompt examples, GUI elements, files, directories, etc.
        * Removed some '()' text from the end of the user functions in the user function documentation.
        * Added some more LaTeX functions for formatting consistency.
        * Defined a new set of LaTeX commands for prompt/script/GUI strings and elements for the user manual.  These will be used to regularize the text throughout the manual, as this is currently quite mixed up.
        * More rearrangements of data model and NOE chapters of the relax manual.  The GUI spin deselection part of the NOE chapter has been shifted into the data model chapter.  And the GUI loading of spins from a sequence file section has been completed.
        * Added screenshots of the spin viewer spin loading wizard sequence.read page.
        * Redesign of the data model chapter of the user manual.  This includes the moving of all of the spin viewer window text and screenshots from the NOE chapter.
        * Shifted the spin viewer screenshots into their own directory.
        * Changed the "View->Spin view" menu item to "View->Spin viewer".
        * Created a directory for screenshots of the spin viewer window operation.
        * The NOE auto-analysis GUI test now checks the support for Trp indole N data as well.
        * The spectrum.read_intensities user function now prints out a list of the intensities read in.  This is for better user feedback as to what the user function has actually done.
        * Created the GUI wizard _apply() method for executing the current page's _apply() method.  This is for the GUI tests to simulate a click on the 'Apply' button.
        * Removed a debugging print out.
        * Modified the NOE system test to catch bug #20120 (https://gna.org/bugs/?20120).
        * Lots of editing of the NOE chapter of the user manual.
        * Significant update of the NOE chapter of the user manual.  The sample script used in this chapter was incredibly out of date.
        * Modified the NOE system test to test the usage of Trp indole 15N data.  This is to catch bug #20119 (https://gna.org/bugs/index.php?20119).
        * Added some Trp peak data (backbone and indole N) to the Sparky steady-state NOE peak lists.  This is in preparation for the modification of the NOE system test to catch bug #20119(https://gna.org/bugs/index.php?20119).
        * Modified the NOE sample script to include Trp indole NH data.
        * Added a step-by-step tutorial for the GUI NOE auto-analysis to the user manual.  This includes 22 screenshots of all the steps.
        * Added a section label.
        * Added some Sparky info to the Rx curve-fitting chapter of the user manual.
        * Allowed the raggedbottom LaTeX setting as this is better for the screenshot layout in the user manual.
        * Added the nth package for the user manual LaTeX compilation.
        * The NOE chapter now points to the recommendations in the Rx fitting chapter.
        * Added a new section called 'From spectra to peak intensities' to the Rx fitting chapter of the manual.  This adds a number of recommendations for high quality relaxation rates.
        * Added the Viles et al., 2001 reference.
        * Small description edit for the relax_data.temp_control user function.
        * Added a LaTeX label to the NOE chapter of the user manual.
        * Added a paragraph to the model-free chapter of the user manual explaining the J(w) equation forms.
        * Added a label to the data model chapter of the user manual.
        * Created an initial rough version of the RSDM chapter of the user manual.
        * Better figure layout in the NOE chapter of the user manual.
        * The relax data model chapter of the user manual now uses the higher quality graphics.
        * Some more high quality graphics.
        * Added more high resolution graphics for use in the relax user manual.
        * Expanded the size of the specific analysis graphics - mainly for use in the relax user manual.
        * Added the specific analysis graphics to the start of each chapter of the relax user manual.
        * Small edit of the 'Citations' chapter of the relax user manual.
        * Added EPS versions of the specific analysis graphics for use in the user manual.
        * Added the Fushman et al., 1999 reference for consistency testing to the intro chapter of the user manual.
        * More chapter cross referencing in the relax user manual.
        * Added the Horne 2007 paper to the 'Citations' chapter of the user manual.  Whitespace has also been cleaned up, and a chapter label added.
        * Added the Horne 2007 paper to the 'Supported NMR theories' subsection of the user manual intro.
        * Shortened the Literature subsection of the intro chapter to point to the citations chapter.  This part of the user manual is now redundant.
        * Small edits of the relax user manual.
        * Edits to the abbreviations chapter of the relax user manual.
        * Added another abbreviation.
        * Expansion of the abbreviations chapter of the relax user manual.
        * Added a tonne of DOI numbers to the relax user manual bibliography.  This will simplify accessing these references for the user.
        * Added and fixed DOI numbers for many bibliographic entries.
        * The LaTeX bibliography style for PhD theses now includes the DOI hyperlink.  This is for the user manual.
        * Slight modification of the DOI hyperlink formatting bibliography style for the user manual.
        * Modified the relax LaTeX bibliography style file relax.bst to convert DOI numbers to hyperlinks.  This is to add links to the references within the relax user manual.
        * Created the new 'Citations' chapter of the relax user manual.  This is to clearly outline to the user the citations required for the various components of relax.
        * Added the Fushman 1999 reference and a few formatting fixes in other references.
        * Improvements to the 'Supported NMR theories' section of the user manual introduction.  This includes the addition of the Morin and Gagne 2009 reference.
        * Added the Morin and Gagne 2009 reference for the consistency testing.
        * Added some more abbreviations to the relax user manual.
        * Created a new chapter for the relax user manual titled 'The relax data model'.
        * Fix for the pipe editor window screenshot width in the relax manual.
        * Converted some more wizard graphics to the EPS format for the user manual.
        * Updates and small expansion of the intro chapter of the relax user manual.
        * The user manual now specifies the repository revision if a non-tagged version is built.  This enables easier tracking and editing of the manual.
        * Updates to the generic_fns.mol_res_spin.id_string_doc documentation structure.
        * Updated the screenshot of the pipe editor window.
        * Created EPS versions of a number of wizard graphics for use in the user manual.
        * Removed some now useless whitespace from the top of each user function subsection of the manual.
        * Redesigned the formatting of the user function chapter of the relax manual.  The fetch_docstrings.py now forces each user function to start in a new column.  This increases the size of the manual, but makes the reading of the user function documentation much easier.  The user function class and function icons (128x128 format) are now placed between the top bar and the subsection title and are left and right justified.  This prettification simply allows the user functions to be more quickly identified.
        * Large expansion of the relax icon set.  All 128x128 versions of the icons used by the user functions have been added as both PNG and gzipped EPS files.  A few gzipped SVG and non-sized icons have been added as well.
        * Large expansion of the Oxygen icons within relax.  All 128x128 versions of the icons used by the user functions have been added as both PNG and gzipped EPS files.  A number of gzipped SVG icons has been added as well.
        * Modified the graphics.fetch_icon function to return different file formats.  This will be used for the relax manual where eps.gz files are required.
        * Improvements to the final section of the relaxation curve-fitting chapter.  The Xmgrace screenshot and page references for the user functions have been added.
        * Added screenshots of Xmgrace displaying relaxation curves.
        * The fetch_docstrings.py now adds LaTeX labels to each user function section.  This has the form of 'uf: ' followed by the user function name, and is for referencing purposes within the main text.
        * Rewrote the relaxation curve-fitting chapter of the relax manual.  This chapter was quite out of date and was of no use to modern relax versions.
        * Redesign of how the GPL license is presented to the user.  The old prompt.gpl module with the version 2 of the license has been deleted.  Now the text form the docs/COPYING file is passed through pydoc.pager for the './relax --licence' and the prompt mode GPL object, and is simply printed to STDOUT for the GUI help system.
        * Import clean ups for the N-state model specific module.
        * Added the 'unit' argument to the dipole_pair.read_dist and dipole_pair.set_dist user functions.  This is to allow distances in Angstroms to be read into relax and converted to meters.


    Bugfixes:
        * Fix for bug #20189 (https://gna.org/bugs/?20189).  The Sequence GUI element can not handle values of None.
        * The citations chapter is now included in the HTML version of the user manual.  For some reason, a file named 'cite.tex' cannot be handled by latex2html.
        * The latex2html compilation of the user manual now ignores the \bibitem{} commands.  This is needed for the HTML version of the user manual.
        * Fixed a section titled 'Introduction' clashing with the intro chapter of the user manual.
        * Fixes for the user function icons in the HTML version of the user manual.  These icons are now placed on the correct HTML page.
        * Removed the text '.eps.gz' from all of the LaTeX included graphics in the user manual.  This allows latex2html to select and use the PNG images instead, producing much better graphics for the online manual (http://www.nmr-relax.com/manual/index.html).
        * Fix for the graphics.fetch_icon() function for when no file format is specified.
        * Elimination of all duplicated chapter, section and subsection titles in the user manual.  This fixes bug #20185 (https://gna.org/bugs/?20185).
        * The HTML files for the user manual now have longer names - this is needed for removing the duplicates.
        * Fix for the duplicate title finding script - the LaTeX and HTML mode alternatives are no longer mixed up.
        * Fix for bug #20177 (https://gna.org/bugs/?20177).  This was simply a lower precision OS/Python/numpy combination causing a test suite failure - there are no practical effects and only the precision of the system/GUI test has been lowered.
        * Another bug fix for the sequence GUI editor window.  This bug was being triggered by the User_functions.test_structure_pdb_read() GUI test which now passes.
        * Small fix for the User_functions.test_structure_pdb_read() GUI test.
        * Fix for bug #20184 (https://gna.org/bugs/?20184).  The behaviour of the gui.string_conv.gui_to_int() and related functions has changed in the last few months and the Sequence_window() GUI element has not changed to match.  This has been fixed and the User_functions.test_structure_pdb_read() GUI test now passes.
        * Fixes for the User_functions.test_structure_pdb_read() GUI test.
        * Fix for bug #20183 (https://gna.org/bugs/?20183) - the failure of the sequence editor window.  The problem was that fields which could be either single values or lists (or tuples) of values were not properly handled.
        * Fix for bug #20182 (https://gna.org/bugs/?20182) - the sequence element window ordering issue.  The sequence element window now has the parent wx.Window element set.  This prevents the main relax window from being set as the parent and hence coming to the front after the sequence element window is launched from a user function window.
        * Fix for bug #20181 (https://gna.org/bugs/?20181) - the GUI sequence editor window TypeError problem.
        * Window ordering bug fix for the user function windows launched from the spin viewer window.  The spin viewer window no longer hides behind the main relax window after the launch of the user function.
        * Bug fix for the repetition of Monte Carlo simulations in the relaxation curve-fitting analyses.  This is in the specific analysis API, so will allow all analysis types to repeat Monte Carlo simulations for error analysis.
        * MS Windows fix - the NOE system and GUI tests are now less strict in checking the errors.
        * Proper bug fix for storing the execution status of wizard and user function pages.  This allows the test suite to pass again.  The execution status is now properly returned from the wizard pages run synchronously (and always set to True for asynchronous calls).
        * Fix for bug #20173 (https://gna.org/bugs/?20173).  The palmer.create user function should have been checking that the diffusion tensor had been initialised.  This is now being performed.
        * Bug fix for the execution of wizard pages - the execution status is now observed.  This fixes bug #20152 (https://gna.org/bugs/?20152).  The problem was that the execution status was being lost in the protected_exec() function.  However as relax errors are caught in the GUI interpreter anyway and the status is returned normally, the protected_exec() wrapper was removed.
        * Bug fix for the creation of the user function GUI pages - the (a)synchronous arg is now observed.  This argument was being ignored, which in some wizards was causing user function calls to be asynchronous.  This can result in racing related crashes.
        * The bruker.read user function now throws a RelaxError when old PDC files are detected.  This is a partial fix for bug #20152 (https://gna.org/bugs/?20152).
        * Fixed the newlines in the sample script in the consistency testing chapter.
        * Fixed the bounding box for the consistency testing figure and also fixed some Latex unfriendly code.  Problems were spotted by Edward d'Auvergne in a post at https://mail.gna.org/public/relax-devel/2012-09/msg00039.html.
        * Fixed a bibliography entry label problem.  This was spotted by Edward d'Auvergne in a post at:https://mail.gna.org/public/relax-devel/2012-09/msg00040.html.
        * Bug fix for the creation of 2D graphs via grace.write for when many data sets exist.  The algorithm for setting the Grace symbol number to be between 1 and 10 was broken!
        * Fix for bug #20133 (https://gna.org/bugs/?20133) - this was simply a missing import.
        * Fix for the spin.create user function documentation - the prompt examples were wrong.
        * Bug fix for the generic_fns.grace.get_data() function.  This was just recently introduced and was triggered by the Relax_fit.test_bug_12670_12679 system test.
        * Fix for bug #20120 (https://gna.org/bugs/?20120), the bad Grace plots with multiple spin types.  The grace data assembly function was not setting the correct index for when a spin type changes to a preexisting type.
        * Bug fix for the reading of Sparky peak lists.  Spin names with numbers at the end were not being correctly identified.  This fix allows Trp indole NE1-HE1 data to be loaded.
        * Bug fix for the loading of peak intensities via spectrum.read_intensities.  The user function could not be applied twice, preventing the loading of data from different spin systems such as Trp indole NH data.
        * Another fix for the relax_data.temp_control description.
        * Fix for the incomplete relax_data.temp_control user function description.
        * Spell fix for the relax_data.temp_calibration user function description.
        * Fixes for the referencing in the J(w) mapping chapter of the user manual.
        * Fixed some citations in the newly introduced model-free J(w) paragraph.
        * Fixed a bunch of links in the development chapter of the user manual.
        * Small fix for the sample script in the relaxation curve-fitting chapter of the relax manual.
        * Small fix for the sample script in the NOE chapter of the relax manual.
        * Bug fix for the RDC Q factor calculations for when the dipolar constants are not all the same.  Now instead of a RelaxError, a warning is given and the Q factor normalised by 2Da^2(4 + 3R)/5 is skipped.  This allows long range and mixed nuclear pairs to be supported.
        * Import additions to fix the epydoc import of the 'sconstruct' script for the API documentation.
        * Epydoc docstring fixes for the API documentation.
        * Import fix for the epydoc building of the API documentation.



Version 2.1.0
(12 July 2012, from /trunk)
http://svn.gna.org/svn/relax/tags/2.1.0

    Features:
        * Update of relax to the GNU General Public License version 3.
        * Introduction of the interatomic data container design for NMR data such as the magnetic dipole-dipole interaction between two spins (including relaxation and RDC data) and NOESY data.
        * Support for absolute or signless RDC values.
        * Creation of a fast molecule, residue and spin data lookup framework using private metadata.


    Changes:
        * Updated the journal reference for the published lactose conformational search scripts.
        * Shifted some of the sample scripts into the analysis specific sub-directories.
        * Increased the size of the test suite warning dialog for MS Windows.
        * Improvements to the skipped test printout from the test suite.  Now all test categories (system, unit and GUI) are printed if a module/package is missing.  This allows for better debugging.
        * Shifted all of the observer registration and unregistration to observer_setup() in the pipe editor.
        * Improved debugging print outs for the observer objects.  The method name is now stored and included in all the observer 'debug>' printouts.
        * Removed the notebook tab deletion from the GUI tests tearDown() method.  This should be performed when a relax reset happens, so it is not needed in the tearDown() method just before the reset() call.
        * Merger of the absolute RDC branch (absolute_rdc).
        * Added support for the absolute or signless RDCs to the N-state model.  This simply propagates the absolute flags into the maths_fns.rdc module functions whereby the absolute RDC values and gradients can be returned.
        * The rdc.read user function backend is now storing the absolute value flag in interatom.absolute_rdc.
        * Converted the N-state model absolute_rdcs.py system test script to the interatomic data design.
        * Created an absolute value version of the synthetic CaM RDC file for the test suite.
        * The rdc.read user function backend now accepts the 'absolute' argument.  This is used to signal that the RDCs are signless absolute values.
        * Created an initial system (and GUI) test for the absolute RDC concept.
        * Added the 'absolute' keyword arg to the rdc.read user function definition.  This will be used to mark RDCs as being unsigned.
        * Merger of the interatomic data container branch (interatomic).
        * Added a new screenshot of the GUI model-free auto-analysis, as it is now quite different.
        * Added a wizard graphic (SVG form) for the 13C-1H dipole-dipole pair.
        * A number of the generic_fns.mol_res_spin functions now accept the pipe argument.  These include name_spin(), set_spin_element(), and set_spin_isotope() and this allows the functions to operate on any data pipe.
        * The dipole_pair.define user function backend now can handle the pipe argument.  This allows it to operate on an alternative data pipe.
        * The State.test_old_state_loading() GUI test now checks the loaded data to a small extent.
        * Better backwards compatibility of old relax results and state XML files for the interatomic design.  The MoleculeContainer._back_compat_hook() method has been shifted into the Relax_data_store._back_compat_hook() method.  This allows the spin containers with attached protons to be converted (with new spin containers for the attached protons added) after loading of the XML state.
        * A small speed up for the model-free duplicate_data() function.  This is used in model selection.
        * The generic_fns.mol_res_spin.index_molecule() function now handles no molecule name given.  If no name is given and only a single molecule is in the current data pipe, then the index of 0 will be returned.
        * The sequence.attach_protons user function now ignores spins with pre-existing attached protons.
        * Improvement for the generic_fns.interatomic.return_interatom_list() function.  The spin ID matching is now through the id_match() function, allowing unique but different spin IDs to be used.  This now matches the return_interatom() behaviour.
        * The relax_io.read_spin_data() function can now handle spin IDs in quotes.
        * The Scientific Python structural object are_bonded() now uses 2.0 Angstrom as a cutoff radius.
        * Added the are_bonded() and get_molecule() methods for the Scientific Python PDB reader.  This is now needed for defining interatomic vectors in the interatomic data design.
        * Expanded the Interatomic.test_manipulation system test to demonstrate a few current failures.
        * Some changes to the Interatomic.test_manipulation system test to better test selection/deselection.
        * The interatomic test suite scripts are now GUI tests as well.
        * Created the new Interatomic system test class for testing out the interatomic data containers.
        * The rdc.read user function can now handle spin IDs in quotation marks.
        * Interatomic data containers can now be selected and deselected.  The user functions select.interatom and deselect.interatom have been created mimicking the equivalent select.spin and deselect.spin functions.  Each interatomic data container now has a select flag.
        * Modified the interatomic_loop() function so that spin IDs can be used to restrict the looping.
        * Modified InteratomContainer.id_match() to handle a single spin ID and to match to all unique IDs.  This uses the spin container _spin_ids list private metadata structure.
        * Split the return_interatom() function into two.  The new return_interatom() function is used for returning single interatomic data containers for perfect matches, whereas the return_interatom_list() function is used to return a list of containers matching a given spin.  This simplifies the behaviour of the module.
        * The RelaxNucleusError and RelaxSpinTypeError can now have the spin ID supplied.
        * Bug fix for the dipole_pair.unit_vectors user function positional checking.  The arg_check.is_float() function needs the raise_error flag turned off.
        * dipole_pair.unit_vectors now raises a RelaxNoInteratomError if not interatomic data is present.
        * The specific API base skip_function() method now returns False.  This was previously raising a RelaxImplementError, but as Monte Carlo simulations now require this function, but returning always False, all analyses will be automatically supported.
        * Eliminated all of the bond length and heteronucleus type value.set units tests.  These are no longer specific analysis parameters.
        * Removed all of the unit tests of the deleted structure.vectors user function.
        * The model-free data_init() method now sets boolean parameters to the default of False.  This excludes the selection flag which is set to True.  The data_init() method no longer uses the data_names() API method but the self.PARAMS.loop() method for returning the parameter names.
        * Improvements for the reading of old 1.2 relax results files for the attached proton spin containers.
        * Improvements and fixes for the generic_fns.relax_data.pack_data() function.  This affects all the relaxation data reading user functions.
        * The structure.get_pos user function now prints out all data and fails if nothing was extracted.  This is to prevent the user from going too far without realising that something is wrong.
        * More print outs and better data loading checks in the dipole_pair user functions.
        * The relax_data.read user function now prints out all of the data read in.  This is to better inform the user that something has happened.
        * The return_spin_from_selection() function now lists all matching spins in RelaxMultiSpinIDError.
        * The return_spin() and return_spin_from_selection() functions can now handle multiple spins.  It the 'multi' flag is supplied, then lists of spins (and associated data) will be returned, rather than a RelaxMultiSpinIDError error raised.
        * Created the list_to_text() RelaxError system function for prettifying the output of RelaxMultiSpinIDError.
        * Expanded RelaxMultiSpinIDError to be able to print out a list of all the matching spin Ids.
        * Improvements for the MoleculeContainer backwards compatibility hook for the creation of proton spins.  The proton element and isotope type is now set to 'H' and '1H' respectively.  This now means that the old XML files require less work by the user to convert to the new interatomic data design.
        * Eliminated the RelaxProtonTypeError error and changed the RelaxSpinTypeError message.
        * The sequence.attach_protons user function now sets the proton element and isotope types.  This reduces the amount of work required from the user.
        * Rearranged the spin.element user function arguments.
        * Created the sequence.attach_proton user function.  This will be useful for analyses which are missing structural data.
        * The dipole_pair user functions now fail if nothing could be done.  This is for the dipole_pair.define, dipole_pair.read_dist, and dipole_pair.set_dist user functions.
        * The Monte Carlo select_all_sims() function is now using the specific skip_function().  This is needed for recreating model-free simulations as deselected proton spin containers now exist.
        * The MoleculeContainer XML backwards compatibility hook now deletes the spin 'r_err' and 'r_sim' vars.
        * Added a backwards compatibility hook for converting old XML files to the interatomic data design.  This will convert the variable names, deleting the old, and create proton spins and interatomic data containers populating them with the old spin parameters.
        * Added a verbose flag to the generic_fns.dipole_pair.define() function.
        * Added a check to the model-free overfit_deselect() to see if a relaxation mechanism is present.
        * Expanded the functionality of the generic_fns.interatomic module.  The copy() and exists_data() functions have been added to copy all interatomic data from one data pipe to another and to check if interatomic data exists within a data pipe respectively.  The create_interatom() function now also accepts a 'pipe' argument so that non-current pipes can be used.
        * Created the RelaxInteratomError and RelaxNoInteratomError classes for interatomic data errors.
        * The interatomic data container now has the dipole_pair flag initialised to False.
        * Expanded the return_interatom() function to handle a single spin ID.  This function now returns a list of matching interatomic data containers.
        * Modified the check_args() method of the dauvergne_protocol model-free auto-analysis for the new data.  The heteronuc_type and proton_type are now in the spin's isotope variable, and the bond length 'r' is now the interatomic distance variable 'r'.  All spin containers and interatomic data containers are being checked.
        * Expanded the RelaxNoValueError to handle one or two spin IDs as arguments.  This is to better identify which spins or interatomic data containers are deficient.
        * The nuclear isotope is now defined via spin.isotope.
        * Eliminated a number of the specific API parameters relating to dipole-dipole interactions.  These are now provided by the spin.isotope user function and the dipole_pair user functions.  The eliminated parameters are: 'r' - replaced by dipole_pair.set_dist or dipole_pair.read_dist, 'xh_vect' - replaced by dipole_pair.unit_vectors, 'heteronuc_type' - replaced by spin.isotope, 'proton_type' - replaced by spin.isotope, and 'attached_proton' - replaced by dipole_pair.define.
        * Created the spin.isotope user function.  This is designed to be a permanent replacement for the specific analysis API 'heteronuc_type' and 'proton_type' parameters.
        * Added the nuclear symbol as a wizard graphic.
        * Added a set of icons for nuclear or isotope related usage.
        * Deletion of the structure.vectors user function as it has been superseded by dipole_pair.unit_vectors.  Only the user function definition has deleted - the backend code will remain so that it can be used internally.
        * Implemented the dipole_pair.unit_vectors user function backend.  This code originates from the generic_fns.structure.main.vectors() function (the structure.vectors user function backend).  The dipole_pair.unit_vectors user function is designed to replace structure.vectors.
        * Created the dipole_pair.unit_vectors user function definition.
        * Created the backend of the dipole_pair.read_dist user function.
        * Created the dipole_pair.read_dist user function definitions.  This new user function is for simplifying the loading of many different interatomic distances into relax.
        * Created a set of icons for the dipole_pair user functions.
        * Shifted the relax_data.dipole_pair user function into the new dipole_pair user function class.  This has also been split into two new user functions:  dipole_pair.define used to set up the magnetic dipole-dipole interactions, and dipole_pair.set_dist used to set up the r^-3 averaged interatomic distances.
        * The relax_data.dipole_pair backend now uses the direct_bond flag.
        * Added CONECT records to the sphere.pdb file to allow connectivities to be more easily determined.  This is for the internal reader, as the current algorithm for finding attached atoms is distance based, and as all N atoms of all residues are at [0, 0, 0], this algorithm fails.
        * Implemented the are_bonded() structural API method for the internal structural object.
        * Created the structural API base are_bonded() method - this is for determining if 2 atoms are bonded.  This is a method stub which raises a RelaxImplementError.
        * Started to add the backend of the relax_data.dipole_pair user function.
        * Shifted the dipole-dipole graphics to the Wizard directory, as this is a wizard graphic.
        * Created graphics for the magnetic dipole-dipole interaction.
        * Removed the bond length from the model-free parameter list.
        * The bond length setting via value.set has no been merged into relax_data.dipole_pair.  This averaged length is dipole-dipole distance and does not need to be a model-free parameter.
        * Added the definition for the new relax_data.dipole_pair user function.
        * Started to change the structure.vectors backend to handle two spin IDs.
        * Expanded the description of the negative gyromagnetic ratio flag for the rdc.read user function.
        * Created the generic_fns.interatomic.interatomic_loop() generator function.
        * The generic_fns.interatomic.create_interatom() function now returns the created container.  This comes from the InteratomicContainer.add_item() method which now also returns the container.
        * Renamed the interatomic function return_container() to return_interatom().  This is to make the name more unique.
        * Shifted some code from InteratomList.add_item() to generic_fns.interatomic.create_interatom().  This is to break a circular import problem.
        * The rdc.read user function backend is now adding the RDCs to the interatomic data containers.
        * Created the generic_fns.interatomic.create_interatom() function for creating interatomic data containers.
        * Added checks to the InteratomList.add_item() method to make sure that the spin IDs already exist.
        * Created the generic_fns.interatomic module and added the return_container() method.
        * Created the InteratomContainer.id_match() method for checking the spin IDs in both directions for a match.
        * Created the interatomic data list and containers, and added these to the data pipe structures.  This is modelled on the molecule/residue/spin structures.  The new containers have is_empty(), from_xml() and to_xml() methods and should be fully functional with the relax infrastructure.
        * Improvement for the RelaxNoVectorsError class - the data pipe name is now optional.  The print outs have been improved as well.
        * The spin container hidden objects are now replicated when the object is copied.  The old Prototype.__deepcopy__() method was skipping all hidden objects, but now only objects starting with '__' are skipped.
        * Created a system test to replicate Romel Bobby's bug #19887.  This is the bug report at https://gna.org/bugs/?19887.
        * Modified the working of the n_state_model.elim_no_prob backend.  This user function is not functional anyway and is not tested by the relax test suite, but will remain as it might be useful in the future.
        * Added the consistency testing documentation to the grace.write and value.* user functions.
        * Converted the consistency testing documentation strings to the Uf_tables and Desc_container design.  This is needed to use the consistency testing documentation within the user function help system.
        * The sequence.read user function now fails with a RelaxError if no sequence data was loaded.  This is for better user feedback.
        * Creation of a fast molecule, residue and spin data lookup framework using private metadata.  This consists of two elements:  The already existing private lookup table now at cdp.mol._spin_id_lookup which is a dictionary with spin IDs as keys and a list of molecule, residue and spin indices as values;  and a set of private variables within the molecule, residue and spin containers which identify the parent container names, numbers and indices.  As all data is private,it will not be visible to the user or be saved in the XML results and save files and should be considered volatile.  All this private metadata is kept up to date via the two new generic_fns.mol_res_spin functions metadata_prune() and metadata_update().  For fast operation, these methods can update specific container subsets via the mol_index, res_index and spin_index arguments.  All parts of relax which modify the data pipe's molecule, residue and spin data structure (the generic_fns.mol_res_spin functions and test suite) call these two functions as needed.  Two auxiliary functions spin_id_variants() and spin_id_variants_elim() have been added to create all possible matching spin ID strings for a given spin (the second created IDs strings which should no longer exist).  The speed ups from this change are significant.  On one system, the system and unit tests decrease from 492.8s/26.4s to 434.3s/25.1s.  On another the decrease is from 330.7s/17.4s to 258.9s/15.4s.  In addition, the pipe argument has been added to the generic_fns.mol_res_spin functions create_molecule(), create_residue(), create_pseudo_spin() and create_spin().  Also, the molecule name will now always be a string.  Previously this was allowed to be an integer.  This is needed for the private metadata functions to operate correctly.   A number of unit tests have been updated for the changes.
        * Removed a hack from the generic_fns.relax_data.pack_data() function for the BMRB support.  This calls the generic_fns.bmrb.generate_sequence() function.  As non-BMRB code paths access the pack_data() function, this is a nasty hack which would have caused problems in the future.
        * Removal of a hack from the generic_fns.bmrb.generate_sequence() function.  This hack was for naming unnamed spins.  But this is not needed as the generic_fns.mol_res_spin.create_spin() function already does this but with many more safety checks.
        * The spin ID lookup table has been made private so that it is not included in the save files.
        * Update and clean up of the model-free LaTeX table generation script.
        * Created the generic_fns.mol_res_spin.return_spin_indices() function to return the index triplet.  This allows a spin ID to be converted into the molecule, residue and spin indices.
        * The generate_spin_id() function now choses to use the spin name instead of number by default.
        * Renamed return_spin_from_id() to return_spin(), and return_spin() to return_spin_from_selection().  This shaves off a number of seconds from the system test - the look up table speed ups will come with support in the other mol_res_spin module functions.
        * return_spin_from_id() now defaults to return_spin() when the spin ID is not in the lookup table.  The slower return_spin() method will allow return_spin_from_id() to always be functional.
        * Added the 'pipe' argument to generic_fns.mol_res_spin.return_spin_from_id().  This is to mimic the return_spin() function.
        * Created generic_fns.mol_res_spin.return_spin_from_id() for returning spin containers from spin IDs.
        * generic_fns.mol_res_spin.create_pseudo_spin() is now adding data to the spin ID look up table.  To support this, the return_residue() method now takes the 'indices' argument and returns the molecule and residue indices.
        * Started to fill up the spin ID look up table.  The index_molecule() and index_residue() functions have been added to determine the MoleculeList and ResidueList indices of given molecules and residues.  These are used by the create_spin for efficiency and to allow the indices (together with the spin index and spin ID string) to be assembled into the look up table.  This table is not used anywhere yet.
        * Initialised a look up table in the cdp.mol structure for faster spin access.  This look up table will be slowly transitioned to, and should significantly speed up certain operations.
        * Created the gui.misc.bitmap_setup() function for handling bitmap alpha correctly on operating systems.  This function is required to handle alpha in bitmap on MS Windows so that regions with partial transparency are not blended into the default dark grey colour of Windows' windows.
        * Added the status/weather-snow-scattered-night Oxygen icon as a wizard graphic for the temperature uf.
        * The about model-free dialog no longer has grey at the bottom in MS Windows.  The wx.ScrolledWindow.GetScrollPixelsPerUnit() function is now used to determine how many pixels the y scrolling is, and rounds up the virtual size based on that.
        * Improved the debugging drawing for the about GUI elements.
        * Hack for the relax_fit C module compilation to detect supported CPUs for Mac OS X cross compilation.


    Bugfixes:
        * Bug fix for the model-free GUI auto-analysis GUI test on MS Windows - the wizards for the CSA value and nuclear isotopes were experiencing racing conditions on MS Windows.
        * Bug fix for MS Windows for the deletion of temporary files in the system tests.  For certain Windows/Python combinations, a WindowsError was being raised saying that the file cannot be deleted as it is being used by another process.
        * Fix for the reporting of skipped GUI tests.  The Frame_order tests skipped because of the missing Scipy module were been labelled as system rather than GUI tests.
        * The GUI show_pipe_editor() method is now the place where the methods are registered with the observers.  This is a partial bug fix for the GUI tests.  The hiding mechanism of the window with unregistration requires this.
        * Bug fix for the pipe editor window hiding and restoring.  All of the Pipe_editor.Show() method has been shifted into the GUI show_pipe_editor() method.  This is needed for the technique of unregistering with the observer objects when the window is closed via a Hide() call.
        * Fix for the State.test_load_state_no_gui() GUI test for handling pipe bundles.
        * Redesign of the setUp() and tearDown() methods of the GUI tests.  This is needed as the current design does not work under MS Windows.  Instead of created a new wx app for each test (this dies in Windows as it looks like only a limited number of toolbars can be created), only one app is created and is recycled.  This design better mimics GUI usage anyway.  This change uncovers a few GUI bugs not caught by the previous design.
        * Bug fix for the GUI test suite setUp() method.  The observer objects are reset at the start to get around a bug when the setUp() method fails for a previous test.
        * Bug fix for the running of the GUI tests on Mac OS X - the relax GUI 'app' needs to be deleted after each test.
        * Bug fix for the Dead_uf_pages.test_mol_create() GUI test for MS Windows.  The _execute_uf() method is now used instead of simulating _ok() calls.
        * Bug fix for the GUI tests on MS Windows.  The GuiTestCase._execute_uf() method now prevents the wizard from running when calling the GUI user function by setting the wx_wizard_run argument to False.  This allows the wizard _ok() call to function on Windows.
        * Bug fix for the Palmer system tests for the changed spin ID syntax.  The spin Gly 2 can no longer be selected with ':2&:Gly', the '&' symbol is not allowed here.
        * Bug fix for the Value GUI input element for integer values.  This is only uncovered when remotely running the GUI - e.g. through the test suite - and an integer value is set.
        * A final fix for bug #19887 (https://gna.org/bugs/?19887).  Now a RelaxError is raised if the number of peak intensities is not the same for all spins.  This occurs in the relaxation curve-fitting overfit_deselect() method.
        * Partial fix for bug #19887 (https://gna.org/bugs/?19887).  The problem is that the number of peak height values was not the same for all spins.  The error message was being caused by the math_fns.relax_fit C object 'setup' function being feed in incorrect values, causing relax to fail directly after the setup() call in specific_fns.relax_fit.minimise().  The number of points was being taken from cdp.relax_times, but in the Relax_fit.test_bug_19887_curvefit_fail system test, one of the 3 spins has 4 points rather than 5.  Now the correct number is sent into setup().
        * Fix for reading of BMRB CSA saveframe data - spin IDs generated from the data now have molecule info.  This is problematic only in certain edge cases, for example a multi-molecule entry.
        * Bug fox for the generic_fns.mol_res_spin.return_spin_indices() function.  The selection object was using the wrong variable name, and the look up table fallback was always on.
        * Bug fix for the relax_data.copy user function - it can now handle spins without relaxation data.
        * Bug fix for the grey about windows on MS Windows.  All the about windows were grey.  The temporary wxPython 2.9.3.1 fix was breaking the Windows GUI.
        * Bug fix for the model-free analysis tab about window - sometimes a grey region would appear at the bottom.  This is a problem in at least GTK+ as scrolling is in increments of 20.
        * Bug fix for sizing of the GUI about dialogs - the virtual sizes are now accurately calculated.  To do this, the window contents (a wx.BufferedDC instance) is created twice, with the virtual window size exactly calculated in the first pass, and then used to set up the device context in the second.  A space is also now added to the end to ensure the border is there.
        * Fixes for the spin.create user function for GUI usage.
        * Fixes for the J(w) mapping and consistency testings scripts so they can run as GUI tests.
        * Fix for the spin.copy user function for GUI use.
        * Bug fix for the return_spin_from_selection() function for the 'multi' flag.  This function needs to handle the case of no spins matching the selection!
        * Bug fix - the spin_id arg for the relax_data.read user function now actually does something.  This argument is passed into the pack_data() function, where it is used to match against the spins matching each file line.  Only if there is a match, is the relaxation data loaded for that spin.
        * Fixes for the reading of relax 1.2 results files.  The new 'H' spin containers are now deselected, and the simulation structure creation has been reverted.



Version 2.0.0
(12 June 2012, from /trunk)
http://svn.gna.org/svn/relax/tags/2.0.0

    Features:
        * A complete restructuring of the user functions - all user functions are automatically generated within all user interfaces (UIs) including the prompt and script UI, and the graphical UI (GUI).
        * The user functions now have special definitions in the 'user_functions' directory making it very simple to add or modify user functions.
        * Big improvements to the help system in the prompt UI mode.  This is now automatically generated when accessed by the user.  Bold font is now used for section titles and keyword arguments, the user function class documentation has been expanded and is now related to the functionality, the user function representation printout is cleaner, and the text is now wrapped for better display on all operating systems.
        * Automatic creation of the "Alphabetical listing of user functions" chapter of the relax manual from the user function definitions.
        * The analysis specific API of the specific_fns directory has been redesigned to extensively use the parameter list objects.  Many API base methods will now automatically work with the parameter list object, removing the need for a analysis specific implementation.
        * The GUI test suite has been significantly expanded.  The system test relax scripts can now be used as GUI tests - the user functions are executed through the self._execute_uf() method which allows execution within all UIs, testing out the different code paths.
        * The specific and GUI tests can now be executed by group.  For example all the model-free system tests can be run with '$ relax -s Mf'.  This is very useful for relax development.
        * The XML formatted results and save files has been redesigned (it has improved, is more accurate, is easier to read in Python version 2.7.3 and above, and contains more metadata) and is now at version 2.
        * The printouts of spin specific data has improved with the addition of an automatic column width algorithm.
        * The addition of a new concept called data pipe bundles - related data pipes can now be grouped together into bundles.  For example in the dauvergne_protocol model-free auto-analysis, all internally generated data pipes are grouped together in the same bundle.
        * Each GUI analysis tab is now associated with a unique data pipe bundle rather than a dedicated data pipe.  This allows for better data pipe handling.
        * Improved BMRB support.  The 'File->Export for BMRB deposition' menu has been added to the GUI which opens a special BMRB export window.
        * More metadata is now read from the NMR-STAR files into the relax data store.
        * The bmrb.display user function is now operational.
        * Big redesign of the Spectral_error_type_page wizard page used in the auto NOE and Rx analyses - this now includes the full description of the spectrum.error_analysis user function, so that the user has easy access to a description of how peak intensity errors and handled.
        * Mac OS X font size and text layout improvements in the GUI.
        * Improvements to the spacing at the top and bottom of the list GUI elements - this includes a spacing before the bottom buttons.
        * The relaxation data 'Add' button in the model-free GUI analysis tab is now a multi-page wizard which allows all of the relaxation data metadata to be input.
        * The model-free GUI analysis tab now has a 'View metadata' button for opening a window displaying all metadata associated with the relaxation data.
        * The model-free GUI analysis tab now has a button for loading relaxation data from Bruker Dynamics Centre files.


    Changes:
        * Spun out the automatic column width formatting code from relax_io.write_spin_data() to write_data().
        * Used some colour for the relax GUI terminating print out asking for citations.
        * The completion of the test suite in the GUI mode now sets the controller main gauge to 100%.
        * Added checks to the BMRB export to make sure all necessary data has been input.  If not, then the Missing_data dialog will be presented to the user to explain what is required.
        * The Missing_data dialog can now have the parent wx element specified.  This is needed when launched from a child window such as the BMRB export window.
        * Improved the robustness of the bmrb.write user function for missing data - this is in the generic_fns.diffusion_tensor.bmrb_write() function, and is for missing atomic information required for the Tensor_list saveframe.
        * The bmrb.read user function is now reading in all of the relaxation data metadata into the data store.
        * Improved the robustness of the bmrb.write user function for missing data - this is in the generic_fns.relax_data.bmrb_write() function, and is for missing atomic information related to relaxation data.
        * The bmrb.read user function is now extracting the thiol state of the molecule.
        * BMRB improvements - the molecule type is now read from the entity record and stored in relax.
        * Added more display tests for the BMRB system test script.
        * BMRB output improvements - deselected spins are no longer skipped and the model-free BMRB output is also more robust to missing data.
        * More extensive testing of the bmrb user functions.
        * Added a call to the bmrb.display user function in the bmrb_rw.py test suite script.
        * Shifted the GUI user function page _format_table() and _table_line() methods into the misc module.  These are now the gui.misc.format_table() and gui.misc.table_line() functions, allowing the code to be used in other parts of the GUI.
        * Decreased the size of all the GUI auto-analysis wizards to fit in a 1024x768 screen.
        * Created a small molecule wizard graphic for the structure.read_xyz user function.
        * Refinement of all of the GUI user function wizard sizes.
        * The default GUI user function description minimum height has been increased to 300 px - removing a lot of scrolled descriptions automatically.
        * Increased the default size of the GUI user functions.
        * Spacing and layout improvements for the GUI user function descriptions.
        * The dauvergne_protocol sample script initial pipe name has been modified to include the pipe bundle.
        * The GUI now sends the pipe bundle name into the relax_fit and noe auto-analyses.
        * The relax_fit and noe auto-analyses now centre around the pipe bundle rather than data pipe name.
        * The about dialog now used the gui.fonts module - this allows the fonts to scale to a decent size on Mac OS X, so that the text is readable.
        * Added a set of roman fonts to the gui.fonts module - this will be used by the about dialogs.
        * Font size improvements for Mac OS X - the fonts are now roughly the same size as on GNU/Linux and MS Windows.  An operating system specific font scaling is now used, with the Mac OS X fonts each being increased by 2 pixels.
        * The dauvergne_protocol auto-analysis now adds the pipe bundle name to all created pipes as a suffix.  This is to uniquely identify the data pipes, and to allow more than one model-free analysis to be executed per relax instance (useful for the GUI).
        * The analysis wizard now suggests the starting data pipe to be named 'origin - ' + pipe_bundle - this allows unique data pipe names for each analysis.
        * Temporarily disabled the Mac OS X task bar icon as it is currently horribly broken in wxPython 2.8 and 2.9.
        * Renamed the GUI toolbar() method to build_toolbar(), as the toolbar object is also called 'toolbar'!
        * Updated the relaxGUI splash screen copyright notice.
        * Improved the button size and spacing in the list GUI elements.
        * The bmrb.write user function now adds the file to the cdp.result_files list and notifies observers.
        * Converted all of the list GUI element 'stretch' args to 'proportion' - instead of a flag, this is now the direct window proportion parameter used in the wx.Sizer.Add() methods.  This has been changed in the BMRB export window so that the central molecule list GUI element is half the size of the others.
        * Created the BMRB export window - this includes the following elements:  A title with description and BMRB icons; the data pipe selection element; the relaxation data meta data GUI element; the molecule list GUI element; the software list GUI element; the script list GUI element; the citation list GUI element; buttons for previewing, exporting, and cancelling.
        * The action_export_bmrb() method now opens the BMRB export window.
        * The base list objects are now updated when pipe changes occur.
        * Created a 100x100 version of the BMRB logo - this will be used for the export window.
        * The spin viewer window now uses graphics.fetch_icon() and shows the button text in the toolbar.
        * Added the mimetypes/text-x-texinfo.png Oxygen icons.  This is for the relaxation data metadata button.
        * Merged the spectrum list GUI element into the base list element.
        * Merged the relaxation data list GUI element with the base list element.  The base list element now has a delete() method, though I'm not sure if it is ever used.  Now all list GUI elements are derived from the Base_list class.  This will simplify changing or improving all of these elements.
        * The base list element now has an Enable() method which simply enables or disables all buttons (as is done in the relaxation data list).  The button size is now specified as a (x, y) tuple.  And the GUI object can now be passed into the elements, as this is needed for the relaxation data metadata window.
        * Large simplifications of the relaxation data metadata list GUI element by using the Base_list class.
        * Modified the molecule list GUI element to use the Base_list base class.  The base list GUI element has also been updated to support popup menus and to change the StaticBox label upon updates.  The base is_complete() method has also been added to always return True.
        * Small updates to the base list GUI element.
        * Created a GUI element for listing and setting the citations relevant for the analysis - this will be used in the BMRB export window.
        * Created a GUI element for listing and setting the scripts used in the analysis - this will be used in the BMRB export window.
        * The GUI user functions now have a subtitle at the top stating the name of the user function - this is to reinforce the user function naming system to the user, and also to clearly identify which window belongs to which user function.
        * Split the software GUI element into the base_list base GUI listing element - this base class will be useful for abstracting many of the list GUI element methods.
        * Created a GUI element for listing and setting the software used in the analysis - this will be used in the BMRB export window.
        * Created a GUI element for listing and setting molecule attributes - this will be used in the BMRB export window.
        * The lists in the GUI user function descriptions are no longer separated by blank lines - this allows long lists to fit much better into the wizard windows.
        * More improvements for the bmrb user function definitions.
        * The GUI user function objects can now be called with the wx_wizard_sync and wx_wizard_modal args.  This is used to force the user function to operate synchronous or asynchronous mode, or to force the user function wizard to be modal.  This will allow a number of hacks to be avoided throughout the GUI.
        * Added a check to the bmrb.write user function to see if the file name has been supplied.  This results in a nicer message for the GUI.
        * The bmrb.display and bmrb.write user functions now have the version defaulting to 3.1.  The choices are now also restricted to 2.1, 3.0, and 3.1.
        * The user function wizard pages now have an on_back() method which unregisters the observer.  This is needed as going back previously did not unregister the observer the object, hence going forwards after going back would fail.
        * The wizard now has an on_back() method available to perform actions when going back.  The on_next() method has been fixed in that it is called even when the page is skipped.
        * Activated the apply and skip buttons in the relaxation data GUI element data reading wizards.
        * The relaxation data 'Add' and Bruker 'Add' buttons now launch wizards whereby the first page is the original relax_data.read or bruker.read user functions, but then this is followed by the relax_data.peak_intensity_type, relax_data.temp_calibration and relax_data.temp_control user functions.  This allows the metadata to be set up prior to the model-free calculations.
        * The relax_data.delete user function now removes all of the metadata associated with the ID.
        * Changes to the relaxation data GUI element button layout.  The buttons are now all of the same width, and the metadata button is now last.
        * The relaxation data GUI element now has a button for opening the relaxation data metadata element.  This 'View metadata' button will launch the new Metadata_window wx.Frame.  This window contains the relaxation data metadata GUI element stretched to fit the window.
        * The relaxation data metadata list GUI element now can stretch to fill the parent, if asked.  This will be used when the list is embedded within a window by itself.
        * Created a GUI element for displaying and editing the relaxation data metadata.  This is very similar to the relaxation data list GUI element, and it will be used in the BMRB export.
        * Refinement of the relax_data.peak_intensity_type user function definition.
        * Big expansion and improvements of the relax_data.temp_control user function definition.  There are also a few edits of the relax_data.temp_calibration definition.
        * Created a 200x200 pixel version of the status.weather-clear Oxygen icon.  This is for the relax_data.temp_calibration and relax_data.temp_control user function wizards.
        * Big expansion and improvements of the relax_data.temp_calibration user function definition.
        * Improvements for the Force_true object for the 'force flag' user function argument types.  This invisible GUI element can now have its value set.  The SetValue() method will internally store the value, and GetValue() will then return this value.  The initial value is True.  This allows the BMRB GUI tests to pass again.
        * The spin.name and spin.element user functions in the BMRB system and GUI tests now use the force flag set to False.  This is to try to replicate the old behaviour of the test and to allow it to pass again.
        * The BMRB icons now also have transparent backgrounds.
        * Made the background of the BMRB wizard graphic transparent - this just looks better.
        * Created a menu entry called 'File->Export for BMRB deposition'.
        * The spectrum and relaxation data list GUI elements now use graphics.fetch_icon for all icons.
        * Renamed some of the methods in the relaxation data list GUI element.
        * The spectrum and relaxation data list GUI elements now use the user function definitions for icons.
        * Changed the relax_fit.relax_time icon to the actions.chronometer Oxygen icon.
        * Added the chronometer.png Oxygen icon.
        * Large expansion of the pop up menu for the spectral list GUI element.  This now includes most of the spectrum and relax_fit user functions.
        * Added accelerator keys for all of the spin viewer window tree pop up menus.
        * Large expansion of the pop up menu for the relaxation data list GUI element.  This now includes most of the relax_data user functions.
        * Implemented the relax_data.frq and relax_data.type user function definitions and backends.
        * Created the Relax_data.test_reset() system test for testing relax_data.frq and relax_data.type.
        * Big reworking of the spin viewer window tree element.  Many new pop up menu entries have been added covering almost all of the molecule, residue, and spin user functions.  The methods bound to the pop up menu entries have all been renamed to 'action_'+type+'_'+user function name.  And the residue and spin changes checking has been fixed to include checks for the naming and numbering.
        * Set the force flag args for a few spin and residue user functions to the 'force flag' arg type.
        * The molecule.name and molecule.type user function force args are now of the 'force flag' arg type.  This hides the arg in the GUI.
        * Added support for the user function arg type 'force flag' to the GUI user functions.  This arg type will, in the GUI, always return True.  This is because a user clicking on 'Ok' or 'Apply' is essentially saying that this operation should be performed.  The special Force_true class was created for these arguments which simply ignores SetValue() calls and always returns True from GetValue() calls.
        * Formatting fixes for the molecule.create user function definition.
        * The relax save and results XML files now include subversion details in the <relax> tag.  This indicates the repository version and the URL, allowing for better debugging.
        * The 'relax --version' print out now includes the full subversion info, if it is a checked out copy.
        * Improvement for the model-free auto-analysis in the GUI.  After execution, the main data pipe of the analysis tab is now set to the 'final' data pipe generated by the dauvergne_protocol.  This means that when switching between analysis tabs, that going back to the model-free tab will make the 'final' data pipe the current one, rather than the data pipe used to initialise the analysis.
        * Better handling of the GUI wizard termination.  The _handler_close() method is now handling the close events and together with the _ok() method,both now execute the current page's on_next() method.  This means that on_next() is called for all avenues for exiting the wizard.  This allows the user function pages to unregister themselves with the observer objects.
        * The wizard window _cancel() method now calls the current page's on_next() method.  This allows the page to clean itself up.
        * The GUI analysis pipe_deletion() method now works with pipe bundles instead of pipe themselves.  This is because the analysis tabs are now associated with the bundles rather than pipes.
        * The 'bundle' arg is now functional in the model_selection user function back end.
        * Added the 'bundle_to' arg to the pipe.copy user function back end.  This arg is now functional.
        * The dauverge_protocol auto-analysis now uses the new 'bundle' user function args.  This is used in the pipe copying to place the newly created pipe and in the model selection, both so that all pipes created during the analysis are located within the pipe bundle reserved for that analysis.
        * The GUI user function window titles are now set to the 'title_short' value.  This is because the long title can be far too long for a GUI window title!
        * The long title or synopsis is now added to the GUI user function description text as italic text.
        * Added the 'bundle' arg to the model_selection user function specification.
        * Improvements to the 'bundle' arg specification of the pipe.create user function.
        * Added the new 'bundle_to' arg to the pipe.copy user function.  This will be used to associated a newly copied data pipe with a pipe bundle.
        * Added some backwards compatibility code for old GUI state files missing pipe bundles.
        * Created a GUI test for loading an old relax 1.3 save state containing GUI analyses.
        * Updated the dauvergne_protocol auto-analysis to spawn all pipes into the named bundle.
        * The generic_fns.pipes.pipe_names() function now can restrict the list of names to a specific bundle.
        * The pipe editor window now handles the pipe bundling concept.  There is a new button for the pipe.bundle user function, a new column showing the pipe bundles, and the pop up menu allows pipes to be associated with bundles if not already bundled.
        * The pipe.bundle user function back end now notifies all the pipe_alteration observers of the change.  This is required for proper GUI interaction.
        * Refinements to the pipe.create user function definitions.
        * The GUI analysis tabs now work with data pipe bundles rather than the original data pipe.  The analysis wizard now uses the unique name for the new data pipe bundle field, and the starting data pipe defaults to 'origin'.  The analysis pages show the bundle name rather than associated data pipe.
        * The pipe.delete user function is now cleaning up the data pipe bundles as needed.  The deleted data pipe name is removed from any bundle it is in, and empty bundles are eliminated.
        * Implemented the generic_fns.pipes.has_bundle() function for determining if a bundle exists.
        * Modified the pipe.display user function backend to show the pipe bundles.  This required the addition of the generic_fns.pipes.get_bundle() function.
        * Implemented the pipe.bundle user function, including the full description and the back end.
        * The data store is_empty() method works again - the pipe_bundles structure is now blacklisted.
        * Shifted the pipe bundle graphic and created a wizard PNG file for the GUI user function.
        * Created icons for the pipe bundle concept.
        * Implemented the generic_fns.pipes.bundle_names() function for returning a list of all pipe bundles.
        * The pipe.create user function now creates pipe bundles in the back end.  The new ds.pipe_bundles dictionary is used to hold lists of pipes associated with the pipe bundle name as the dictionary keys.  The 'bundle' arg is passed into the ds.add() method for storage.
        * Added the 'bundle' keyword arg to the pipe.create user function definition.
        * Preparation for the implementation of pipe bundle concept - addition of system and GUI tests.  This new pipe bundling concept is simply a way of grouping data pipes together.  This will be useful for:  grouping and categorisation of data pipes when multiple analyses are performed, the model-free dauvergne_protocol auto-analysis will place all the data pipes it creates into one bundle, for the GUI mode analyses will be linked to pipe bundles rather than data pipes.  This will allow switching data pipes to activate the correct analysis.
        * The 'verbatim' user function description elements are now properly formatted in the GUI.  These elements now use the font.modern_small formatting to have fixed-width characters.
        * Table formatting improvements for the GUI user function descriptions.
        * Improved the whitespace formatting of the spin data write out of relax_io.write_spin_data().  Now the column sizes are dynamically changed to match the data being written out.  This is to fix the ugly write outs for when the name of the molecule is very long.
        * Replaced all mention of 'arguments' from the user function docstrings with human readable text.
        * The state.load user function will now recreate the GUI tabs.  For this, the new state_load observer object has been created.  The GUI analysis load_from_store() is registered with this object.  And to prevent fatal racing in the GUI, the state.load user function operation is now synchronous.  The state.load and state.save file arg defaults are now also set to 'state.bz2'.
        * Removed a printout in the API documentation compilation.
        * All of the user_function.object.Table instances in the specific code descriptions are now private.  This hides them from the specific API, and allows the unit tests to pass.
        * Removed the vertical lines in the tables of the prompt UI help strings.  The tables now look much more professional.
        * The GUI user functions now use the new Desc_container and Table user function classes.  The descriptions for the user function wizard pages are now being taken from the new user_functions.objects.Desc_container objects, lists of which are the user function definition 'desc' objects.  The tables via the user_functions.objects.Table object is being formatted as in the prompt user function help text, though without vertical lines.  The lists and itemised lists are currently formatted the same as in the prompt UI.
        * The Desc_container.element_loop() method can now yield the title too, if asked.
        * Better spacing in the list of tables section of the PDF user manual.
        * Complete rewrite of the docs.latex.fetch_docstrings module.  This is a significant simplification for the creating of the user function documentation within the user manual.  Some of the long list of changes include:  The file docs/latex/fetch_docstrings.py is no longer an executable script and now operates solely as a Python module; all of the original docstring section parsing code has been eliminated; the searching for user functions in the prompt UI namespace has been replaced; the new user function definitions are directly used and the documentation for each user function section generated via the self.build_*() methods; the complicated ascii table parsing and rebuilding into a LaTeX table has been eliminated; the self.write_*() methods have been created for building the various sections of the user function documentation (paragraphs, verbatim text, prompt examples, lists, itemised lists, and tables); tables are no longer duplicated, triplicated, etc. and instead a reference to the first instance of  the table is inserted - this is a significant space saver as one of the copies of the multi-page X11 colour table is removed.
        * Renamed the Uf_tables.add_table() 'title' arg to 'caption', and added the new 'caption_short' arg.  The name change is fairly logical, as this is a caption.  The 'caption_short' arg will be used for the list of tables in the LaTeX user manual.
        * The Molmol colour table is no longer a LaTeX longtable in the user manual.
        * The prompt UI table creation is now using the Table.spacing variable for adding empty lines between rows.
        * The Monte Carlo description now uses an itemised list for the listing of the steps involved.
        * The prompt UI help string construction code is now handling the new Uf_tables singleton.
        * Added a check to Uf_tables.get_table() to make sure that the table corresponding to the label exists.
        * Added a check to Desc_container.add_table() to make sure the label is a string.
        * All of the user function documentation tables now use the new Uf_tables singleton structure.  The special properties for the colour module tables (longtables and now spacing) have been added as well.
        * Created a new way of defining and inputting tables into the user function descriptions.  This introduces the user_functions.objects.Table for holding all the table data and metadata, and the user_functions.data.Uf_tables singleton object for holding all the tables.  This design will allow more metadata (for example using longtables in the LaTeX user manual) to be specified.  The singleton collection of tables with unique labels will also allow the elimination of duplicated tables in the PDF and HTML user manuals.  The new table title metadata will also be used for the table headings in the user manuals.
        * Converted a number of add_verbatim() calls to add_item_list_element() with items of None.  This allows for proper formatting and indentation of equations.  In the future, a possible add_equation() method might be added to provide text and LaTeX representations of equations in the user function documentation.
        * Itemised lists without items are now supported in the prompt help strings.  This is to mimic the LaTeX behaviour to allow lists with no 'bullets'.
        * Shifted the prompt examples to the end of the description for the value.display user function.
        * Converted all of the user functions to use the Desc_container class design.  All of the user function descriptions, prompt examples, and additional documentation scattered around the relax sources have been merged into the Uf_info.desc list of Desc_container objects.
        * The 'prompt_examples' and 'additional' user function structures are no longer passed into the prompt objects.
        * Removed the 'prompt_examples' and 'additional' variables from the Uf_info containers.  These have been superseded by the Desc_container objects.
        * Prompt examples are now followed by 2 newlines in the prompt help strings.  This restores much of the original formatting for these examples.
        * Added support for no spacing in tables for the prompt help strings.  The Desc_container.add_table_titles() method now accepts and stores the 'spacing' arg.  This is passed all the way into the prompt help system to format the tables with.
        * Added a check in the prompt help _build_doc() method for the user function description.  This should, together with the _build_doc() unit tests, help to uncover all unconverted user function 'desc' variables.
        * Created an algorithm for wrapping table columns to fit within status.text_width.  This is for the prompt user function docstring tables.  The columns are now dynamically wrapped so that the table will not be wider than the given width.  For example the value.set user function description table would normally have a total width of 238 characters, but this now fits within one screen of text under all operating systems.
        * Created two unit tests for the _build_doc() methods of the prompt user function objects.  This is for the prompt user function class objects and the user function objects themselves.  The _build_doc() methods are used to generate the prompt help strings.
        * Converted all of the OpenDX user functions to the new Desc_container design.  This tests out the use of 'additional' outside documentation.
        * Improved the user function class prompt help string.  The user function list now uses bold text, and the user function title is also now given.
        * The prompt help string for user function classes now includes info about the member user functions.
        * The Uf_info.uf_loop() method can now restrict the looping over a given user function class.
        * Large improvements to the prompt help strings for the user function classes.  These are now formatted with section using bold text.
        * The user function default args prompt help string text is now wrapped.
        * Removed the starting newline from the user function prompt help string.
        * Converted the calc, grid_search and minimise user function descriptions to use Desc_container.
        * Tables in the user function descriptions are now formatted for the prompt help strings.  This is for the Desc_container objects.  The list of lists are now converted to the text format originally used for the user function docstrings.
        * Converted all of the alignment tensor user functions to the new Desc_container design.
        * Itemised lists and verbatim text are now formatted properly for the prompt help strings.
        * Converted align_tensor.init to the Desc_container object design to test itemised lists.
        * The Desc_container object now supports itemised lists.
        * Lists are now formatted for the prompt user function help strings from the Desc_container objects.
        * Converted the align_tensor.display user function to the new Desc_container design.  This is to test out the list generation.
        * The Desc_container.add_list_element() method now groups list elements together.
        * Converted the prompt user function objects to use the new Desc_container objects for the help strings.
        * Started to redesign the user function definition descriptions.  The desc object has been converted into a list which will contain instances of the new Desc_container class.  This class will hold the description information as blocks of text, including unformatted paragraphs, verbatim text, lists, tables, and relax prompt examples.  The object has a number of methods used for inputting all of the information, as well as extracting it.  The information in the Desc_container object is not formatted, for example tables will be stored as lists of lists.  This will remove the need for parsing list, tables, verbatim text, etc. by the docs.latex.fetch_docstrings module.  But these will need to be recreated for the prompt help strings, for the GUI user function descriptions, and for the user manual.
        * Converted the align_tensor.copy user function description to the new design.  This is a test for the implementation of the description abstraction through the Desc_container objects.  The 'desc', 'additional', and 'prompt examples' will all be merged into one 'desc'structure.
        * Converted a few user functions to use the special "spin ID" arg type.
        * Converted the structure.vectors spin_id arg to the special "spin ID" type.  This is to improve vector loading in the GUI.
        * Increased the size of the unit vector loading wizard in the model-free analysis.  This now matches the structure.read_pdb user function size and allows it to fit.
        * The min length is now handled much better in the Combo_list GUI input element.
        * The GUI user function object create_wizard() method now returns True upon success.  This is needed for calls to these objects.
        * The GUI user functions now called by the results viewer window now have the parent set to this window.
        * The GUI user function page update_args() method now has a docstring and returns True when successful.
        * Rearranged the spin.name args and converted the spin ID to the special spin ID type.
        * Prevention of multiple RelaxErrors from the user functions.  The update_args() method returns False if an error occurred on updating the list of choices for an arg.  This is now caught by all parts of the code where it is called, preventing further execution.
        * Improvements to the structure.load_spins user function definition.  The spin_id arg now uses the special 'spin ID' arg type for the spin ID GUI input element.
        * A number of improvements for the spin ID GUI input element.  This includes:  the use of SetValue() for strings not in the list of choices; defaulting the choices to ['@N', '@C', '@H', '@O', '@P'] if not supplied; a tooltip white space fix; and removal of the None element in the list of choices, as this is not a read only box.
        * Increased the size of the spin loading wizard to match that of structure.read_pdb.
        * The Value GUI input element UpdateChoices() method now handles non-selection strings in the ComboBox.  The SetStringSelection() method is now only used when the combo default is one of the choices, and SetValue() when not in the list of choices.
        * Decreased the amount of waiting time in the GUI interpreter flush() method.  This will allow speed ups in certain parts of relax (for example some GUI tests).
        * The GUI test _execute_uf() base method now allows the wizard run() method to be executed.  This gives a better work out of the user functions and matches more closely to what a user will experience.
        * Deleted a ton of now unused and useless code from gui.analyses.results_analysis.
        * Print statement conversions to function calls for Python 3.x.  All non-debugging print statements are now function calls.  The debugging printouts have been deleted.
        * Complete redesign and creation of the 2nd version of the relax XML format for save and results files.  This is a BIG set of changes!  It includes the following:  the XML files now have the new 'file_version' attribute within the 'relax' XML element, this is now set to '2', and if unset it is assumed that the file version should be 1; the file_version integer value is now propagated through all of the from_xml() methods so it can be passed into the data.relax_xml.xml_to_object() function - this prevents a mixture of v1 and v2being assumed for different parts of the XML; an XML namespace fix - the xmlns="http://www.nmr-relax.com" attribute is now finally visible; the data.relax_xml.object_to_xml() function has been added for creating the new relax XML syntax - this will handle and convert many more basic Python object types into IEEE-754 byte arrays, for example lists and dictionaries of floats, or numpy vectors and matrices, and this function is now used throughout the code base for converting Python objects to XML; the data.relax_xml.xml_to_object() function has been expanded to match the functionality of data.relax_xml.object_to_xml(); the Python object XML elements now have the 'type' attribute indicating the Python object type - this is important for the processing of the file, especially for handling all types of numpy structures; the Python object value is now stored in a sub XML element called '<value>' - if it is a float, or is a simple type which contains floats, then the sub XML element <ieee_754_byte_array> is created for storing a full precision version of the floats; the v1 and v2 of the format together with the pre- and post-Python 2.7.3 XML toprettyxml() changes are now represented as test_suite/shared_data/model_free/OMP/final_results_trunc_1.3*.bz2 files, and a 5th file is added to test the IEEE-754 conversions by corrupting many of the floats.
        * The arg_check.is_float_matrix() function can now handle empty lists.
        * Deleted the NOE data_names() specific analysis method.  This should operate through the base methods now.
        * Spelling fix - converted the noun 'print out' to 'printout'.
        * Added minimisation parameters to the N-state model specific analysis parameter list.
        * Updated the OMP model-free results file in the test suite shared data directories for recent changes.  The ordering of model-free parameters is slightly different now.
        * The 'select' global param can have a corresponding MC simulation structure.
        * The specific API data_names() method now accepts the 'scope' argument.  This is used to differentiate global verses spin parameters.
        * Lots of improvements for the specification of the model-free global and spin parameters.
        * The specific API param list base_loop() and loop() methods now match against the parameter scope.  This allows for the differentiation of global from spin parameters.
        * Improvements and fixes for the minimisation parameters in the specific API param list object.
        * The specific API param list get_desc() method now skips the error and sim structures.
        * Removed a number of specific API methods from the model-free analysis.  These are now provided by the base class.
        * Large reworking of the specific analysis API.  Many specific methods relating to parameters have been shifted into the API base class.  These include: data_names(), data_type(), default_value(), return_conversion_factor(), return_data_desc(), return_data_name(), return_grace_string(), return_units().  These are now essentially provided by the parameter list object.  All of the global and spin parameter lists have now also been merged into the single 'self.PARAMS' structure.
        * The py_type is now set for the minimisation parameters.
        * Renamed 'param_set' to 'set' in the specific API param list object.
        * Split the specific API parameter object loop() method into two.  The new base_loop() method loops over the parameter names according to set, whereas the loop() method now supports and returns the error and simulation parameter names as well, if set.
        * The specific API param list object now sets up a number of spin params and min params.  The spin 'select' and 'fixed' parameters are set up in the __init__() method, whereas the add_min_data() method will be used to add minimisation parameters.
        * Added the 'scope' arg to the specific API param list add() method.  This will be used to merge the GLOBAL_PARAMS and SPIN_PARAMS lists into one.
        * Created the specific API param list loop() method for looping over parameter names.
        * All the get_*() methods of the specific API parameter list objects now call self.check_param().  This new check_param() method raises a RelaxError if the parameter is unknown.
        * The parameter set 'params' or 'generic' can now be specified in the specific API parameter lists.
        * The GUI tests _execute_uf() base method now simulates a click on the 'ok' button.  This gives the user function wizards a much deeper work out.
        * Renamed the Python type arg from 'type' to 'py_type'.
        * Added the 'min_stats' flag to the specific API parameter list objects.  This indicates if the minimisation statistics are part of the parameter set.  This is a flag to the __init__() method, as it applies to the entire parameter list.
        * Expanded the specific API parameter list object to include the Python type and error and sim flags.  This includes the addition of the get_err(), get_sim(), and get_type() methods.
        * Created the Dead_uf_pages.test_mol_create() GUI test demonstrating a failure in the user functions.  This mimics a click on the 'ok' buttons, showing a problem with running a GUI user function twice.
        * The relax GUI state_load() method now checks if the data store is empty.  Previously a warning was only giving is analysis tabs are loaded.  Now the warning occurs whenever there is data in the relax data store.
        * Eliminated all of the wizard GUI input methods.  These are now all covered by the gui.input_elements package, so are no longer needed.  The analysis wizard had to be converted to using the package, but the methods are now no longer used.
        * Converted the spin_id_element() wizard method into the gui.input_elements.spin_id.Spin_id GUI element.
        * The gui.string_conv.list_to_gui() function can now handle numpy arrays.
        * The structure.rotate R arg now defaults to the identity matrix.  This is simply for the GUI.
        * The frame order system tests are now being run as GUI tests as well.
        * Converted all of the frame order system test scripts to be executable as GUI tests.
        * GUI test scripts are now executed via prompt.interpreter.exec_script().  This allows the preservation of imports within the scripts.  The old execfile() method was causing the 'globals' to be overwritten, hence imports in the scripts are not visible inside methods or classes.
        * The GUI auto-generated user function SetValue() method now skips function and function arg arguments.  These are not supported in the GUI.
        * Loosened the checking conditions for the test_set_value() J(w) mapping system (and GUI) test.  Just like the consistency testing, the GUI string conversions to and from floats introduces a slight truncation.
        * The consistency testing test_set_value() system (and GUI) test has been made less strict.  The conversion of the bond length and CSA values to GUI strings and back to floats causes a slight numerical truncation.
        * The specific analysis API base return_data_desc() now has a basic implementation.  This will search through the global and then spin parameters objects, returning whatever is found.
        * The specific analysis API base method calls to RelaxImplementError now send in the function name.  This allows for better identification of what needs to be implemented.
        * The specific analysis base API default_value() method is now functional.  Rather than raising a RelaxImplementError, this method now searches in the global parameters then the spin parameters for a default value.
        * Shifted out the interpreter components of the J(w) mapping tests into scripts.  This allows the tests to work in the GUI test framework.
        * Converted the consistency tests script to the new _execute_uf() design.  This allows it to work with the GUI for the GUI tests.
        * The jw_mapping system tests are now run as GUI tests.
        * The user function intro string echoing has been turned back on for the GUI.  The removal of the need for the prompt UI interface for the GUI user functions removed the intro print outs.  These have been reimplemented within the GUI code now.
        * Renamed the status.prompt_intro flag to status.uf_intro.  This is because the flag will be used in all UIs.
        * The sequence.write user function back end now defaults to True for all sequence columns.
        * The grid_search user function inc argument cannot be None.
        * Converted all of the prompt unit tests to the new auto-generated user function design.
        * Updated the model-free auto-analysis GUI test to pass.  Changes include opening and closing the about dialog, loading the sequence via the spin viewer window - testing this GUI element for the first time and the use of the methods behind the specific value.set buttons.
        * The model-free GUI auto-analysis 'About' dialog is now stored as a class instance variable.  This allows it to be manipulated remotely, for example by the GUI tests.
        * The GUI user functions are now going straight to the back end rather than through the prompt.  The GUI user functions were previously passing through the prompt UI user functions for argument checking, which then passed on to the back end.  Now the prompt is bypassed, and the back end is being directly called.  This should speed up the user functions, and specifically the GUI tests.
        * The prompt UI versions of the auto-generated user functions are now stored in self._uf_dict.  This is a dictionary whereby the keys are the full user function names as text.  This is designed for speed, so that the user function object can be retrieved much faster.
        * All the wizard method 'event' arguments have been converted to keyword arguments.  This is for better remote control, for example by the GUI tests.
        * All the model-free GUI auto-analysis method 'event' arguments have been converted to keyword arguments.  This is for better remote control, for example by the GUI tests.
        * Converted many GUI functions expecting a wx.Event to have the event as an optional argument.  These are now keyword arguments defaulting to None.  This allows remote control of GUI elements, which is needed for the GUI tests.
        * Removed the reinitialisation of the relax data store GUI object in the GUI test tearDown() method.  This is not needed as it is done by the data store reset anyway.
        * Removed a time.sleep() call which slows down the GUI tests by a significant amount.  This adds 0.5 seconds per user function which display info.  For example this is 8 seconds for just the Bmrb GUI tests!  This delay is not necessary, so has been eliminated.
        * The user function docstrings are now created when the help system is invoked.  This prevents all user function docstrings from being built at the start, or any time the interpreter class is instantiated.  Instead the docstrings are created on demand.  Therefore for most relax usage, the docstrings for most user functions will be rarely built.  This decreases start times of ~6 seconds down to ~0.06 seconds!
        * The GUI tests are now recycling the GUI user function wizards and pages as well.  This required a number of modifications; the user function object wizard creation has been shifted into the create_wizard() method; the status.gui_uf_force_sync flag has been introduced to force synchronous operation of the GUI user functions; the wx_wizard_run keyword arg has been added to the user function object to prevent the automatic running of the wizard; the GUI test tearDown() base method no longer destroys the GUI or wizards, as they are needed in subsequent tests.
        * Removed the useless GUI interpreter flush() call in the GUI tests base _execute_uf() call.  This is not needed as the GUI user function calls are synchronous.  This cuts the GUI test running time down by about 1/4!
        * The wizards for the individual user function pages are now recycled.  This should speed up the GUI (and the GUI tests massively).  Closing the wizard calls the Close() rather than Destroy() method, so the wizards are still in memory.  A new call to an old GUI user function object will simply call SetValue() for all keyword arg GUI elements, hence reset the element.  The Wizard GUI object has been modified to only add the buttons if they do not currently exist.  Without this, a new set of buttons is added each time the user function wizard appears.
        * The GUI base class now has access to math.pi.  This is necessary as the system test scripts are run in this namespace rather than the interpreter namespace in which pi is defined.
        * The Combo_list GUI input element can now handle values typed out by the user.  This affects both the GetValue() and SetValue() methods.
        * The value.set user function 'param' argument can now be manually set by the user rather than selected.  A number of N-state model parameters require this.
        * Better handling of empty data in the Sequence.GetValue() method.
        * The non-supplied user function arguments in the GUI tests are now set to the default.  This is for the _execute_uf() base method, and is essential for the free file format where the column arguments must, in many cases, be set to None.
        * Updates to the N-state model specific code.  The default_value() and return_data_desc() methods are now defined, and the data_names() method returns a few parameter names.
        * The Sequence.GetValue() method now properly handles the Combo_list and single values.
        * The Combo_list.GetValue() method now returns a proper list of values rather than the string representation.
        * The Value GUI input element UpdateChoices() method now restores the current selection.  This matches the Combo_list GUI element changes.
        * Renamed all of the ResetChoices() GUI methods to UpdateChoices().  This is because they are for updating a list while retaining the current selection.
        * The Combo_list GUI input element ResetChoices() method now remembers the current selection.  This allows the selection to be restored when the element is updated, rather than resetting to the default value.
        * The GUI test _execute_uf() base method now handles non-keyword arguments, by converting them to keyword arguments.
        * All system test scripts are now executed through the base script_exec() method.  This allows them to be run in the GUI tests as well.
        * The execute_uf() method is now private.
        * Added all of the N-state model system tests as GUI tests.
        * Modified the GUI tests so that they can operate in the same way as the system tests.  Now entire test suite classes can be executed in isolation by typing, for example: "$ relax --gui-test N_state_model".
        * Converted all of the N-state model scripts to use the new self._execute_uf() interface.
        * Added some error checking for the system test class execution.  This is for better user feedback for when the user supplied class does not exist.
        * Entire classes of system tests can now executed.  Rather than running the entire system test suite or individual tests, the system tests can now be run by class.  For example to execute all of the N-state model system tests, just type: "$ relax -s N_state_model".
        * Eliminated the self._test_dir test class variable.  The system and GUI tests will now use the same script path.
        * Modified and renamed the self._execute_uf() method so that it will work with the system test scripts.  The file and directory arguments are now merged, as required by the GUI user function pages.
        * Converted the bmrb_rw.py system test script to use the new prompt self._execute_uf() method.  The GUI test framework will need slight modification to use this script directly still.
        * Created a special private method for the prompt/script UIs for executing user functions.  This self._execute_uf() method will be used for the sharing of scripts in the system and GUI tests.
        * Re-factored the system and GUI tests for code sharing.  The GUI tests now can inherit tests from the system tests.  This is done for the BMRB system tests,both of which now run as GUI tests.  For this, a test class specific script_exec() method has been added.  For the system tests, it passes the system tests script into the interpreter.  For the GUI tests, it executes the script using the function locals so that the GUI test execute_uf() method is accessible.
        * Created a pair of Python object to GUI string and reverse conversion functions.
        * Spun out the GUI sting conversion functions from the gui.misc module into the new string_conv module.  This set of functions is now large and diverse enough to justify a separate module, as the remaining three functions of gui.misc have nothing to do with GUI strings.
        * The Sequence GUI element now better handles single values in the GetValue() method.
        * The specific_fns get_specific_fn() function now determines the data pipe type, if not supplied.
        * Improved the value.set user function definitions.
        * The model-free GUI auto-analysis now sets the default value for the parameter buttons.  The CSA, bond length, proton and heteronucleus type buttons now launch the GUI user function with the default value set.
        * The Sequence GUI input element can now handle single values passed into SetValue().
        * The user function page is now updated prior to setting any argument values.  This is necessary for when a value from a pre-defined list is to be selected.  Without the update,the list will be blank and the selection will not work.
        * The user function GUI objects can now be called with their argument values.  This allows the argument to be set upon page creation.
        * The auto-generated file and dir selection dialogs now have wildcards and styles.  This is provided through the new 'wiz_filesel_wildcard', 'wiz_filesel_style' and 'wiz_dirsel_style' user function argument arguments which are then passed on to the file and dir selection GUI elements.  All user functions dealing with files and directories have been updated.
        * Updated the model-free auto-analysis GUI test for the new user function design.
        * The Value GUI element as a ComboBox can now handle input values which are not in the list.  This allows user functions with the 'wiz_combo_choices' argument argument set and the 'wiz_read_only' arg arg of False to function.  This is for the user to select from a list of pre-defined defaults, or input their own value.
        * The GUI tests base execute_uf() method now runs all user functions in synchronous mode.  In combination with the previous gui_raise() change, this allows the GUI tests to actually fail when a RelaxError occurs.
        * The gui_raise() function now simply re-raises the RelaxError when in test mode.  This allows the GUI test to properly fail.
        * Removed all of the dir user function arguments in the BMRB GUI test.  These need to be part of the file argument, as the file and dir arguments are merged into one GUI file selection element.
        * The Combo_list GUI input element SetValue() method now handles single values and lists.  This is required for the GUI tests.
        * The ComboBox data values are now set to the choices in the __init__() method if not given.  This is required by the GUI tests, as the ResetChoices() method which does the same thing has not been called.
        * Shifted the combo_list GUI element into the gui.input_elements package.
        * The NOE auto-analysis GUI test has been converted to the new auto-generated user function design.
        * The NOE auto-analysis peak loading wizard has been converted to the new auto-generated user function design.
        * The prompt-based interpreter no longer sets the status.prompt_intro flag in the __init__() method.  This flag is now set by the instantiation of the singleton status object.  This prevents multiple calls to the Interpreter.__init__() method overwriting this flag.  This fixes problems in the GUI tests.
        * The GUI tests base class execute_uf() method will now try to set all keyword arguments.  This allows the user functions with free file format keyword arguments to be operational.
        * The Combo_list GUI element now handles the wiz_combo_list_min user function argument argument.  If not enough elements are set, Combo_list.GetValue() will return None.  This is caught by the auto-generated GUI user functions on_execute() method, preventing the execution of the user function.
        * The spectrum.replicated user function back end now checks for lists of None or of 1 element.
        * Renamed the user function argument argument wiz_combo_list_size to wiz_combo_list_min.  This will be used by the Combo_list object to ensure a minimum length.
        * The Rx auto-analysis peak loading wizard has been converted to the new auto-generated user function design.
        * Individual elements of the Sequence and Combo_list GUI element can now be set via the SetValue() method.  The Sequence.SetValue() method now accepts the index arg, and this is passed onto the Combo_list.SetValue() method.  The individual elements of the Sequence element still cannot be set via the index.
        * The free file format object can now be remotely controlled in the auto-generated user functions.  This allows the test suite to set these values.  For this, a special Free_file_format.SetValue()method was created, and the user function SetValue() method will call this when needed.
        * Removed the desc_short arguments to the Sequence* GUI input element classes.  These do not exist.
        * The GUI test base execute_uf() method now only sets an argument if the argument has a corresponding GUI element.
        * Missing import causing all GUI tests to fail.
        * Edited all the module docstrings in the user_functions package.
        * Split up the gui.wizard_elements into a number of modules in the new gui.input_elements package.
        * The user function GUI page arguments are now updated after execution of the user function.  This allows ComboBox lists to be dynamically updated, and is useful for when the user clicks on 'Apply'.
        * Created the Free_file_format.GetValue() method for returning a dictionary of arguments.  This abstracts the GUI element's input fields.
        * Redesigned the set up of the user function arguments in the GUI pages.  The wizard element_*() methods have been removed as these were pointless wrappers.  The Uf_page add_contents() method now builds the argument GUI elements and stores them in the self.uf_args dictionary.  The wizard methods Clear(), GetValue(), ResetChoices() and SetValue() have been shifted into the Uf_page class as these are only for the auto-generated user functions.
        * More independence for the wizard_elements - the height of the element must now be passed in as an argument.
        * Started to make the wizard_elements module classes independent of the wizard.  The references to parent._div_left have been eliminated, this is now expected to be passed in by the parent which has that variable as the divider argument.
        * Converted the Interpreter.script() method into a proper user function.  This pseudo user function was no longer functional after the auto-generation changes.
        * Redesigned the prompt help system for the auto-generated user functions.  The documentation is closer to the style in the relax manual, including 'Synopsis' and 'Default' sections (i.e. see http://www.nmr-relax.com/manual/value_set.html).
        * The _build_doc() method now returns the documentation.
        * Eliminated the build_doc() function as this is no longer used.  The new auto-generated user functions use a variant of this function as the _build_doc() method.
        * The uf_docstring functions are no longer private.
        * Renamed the 'base_class' module to 'uf_docstring'.  This module now only contains functions relating to the auto-generated user function docstrings.
        * Shifted the prompt.base_class._strip_lead() function to relax_string.strip_lead().
        * Renamed the 'doc_builder' module to 'relax_string'.  This will be used to hold more string related functions used throughout relax.
        * The status.text_width variable is now used to wrap the user function docstrings.  This is for the prompt help system.
        * Shifted the prompt ps1, ps2 and ps3 variables into the 'interpreter' module.  This is the only place they are used, so they are better there.
        * Eliminated the defunct User_fn_class base class.
        * The Sequence GUI elements now default to not being read-only.
        * The frq user function class submenu mnemonic is now 'f', conforming to the other user function classes.
        * Improved the keyboard mnemonics for the user function sub-menus.  There are no longer any clashing letters.
        * The user function menu has been split in half as it was far too long.
        * The spin viewer window is now using the new build_uf_menu() function for its menus.
        * Shifted the user function menu creation into gui.uf_objects.build_uf_menus().  This will allow the code to be reused by the spin viewer window.
        * The GUI user function storage object now populated itself.  This singleton object is no longer populated from the main GUI object, shifting the auto_generate()method code into the singleton instantiation.  The user function __call__() method not extracts the main window GUI object for use as the parent of the wizards, if a parent is not supplied.
        * Removed the dependence on the old GUI user function system.  Now the GUI user function storage object is used throughout.
        * The user function GUI objects can now be called with the 'parent' keyword argument.  This allows a window other than the main relax window to be the parent, preventing the main window from always coming to the front.
        * Converted all of the GUI code to use the auto-generated user function design and storage object.
        * The Uf_page.create_page() method now accepts the 'sync' argument for deciding user function operation.
        * Shifted the user function page creation into the Uf_object.create_page() method.  This will be useful for the creation of the special wizards which are composed of many user function pages strung together.  In this case, the __call__() method which creates and packs the page into a Wiz_window instance can be bypassed.
        * The Spectral_error_type_page class now inherits from Wiz_page as UF_page has been eliminated.
        * Eliminated the gui.uf_pages package.  This removes a lot of code and many modules!  This has all been rendered useless by the auto-generated user functions.
        * Eliminated the old user function menu system.  The auto-generated menu system is now complete, so the old system is now of no use.
        * Improved the argument description by making it more readable.
        * Renamed the 'user_functions' module to 'uf_objects'.  This is due to a name clash with the 'user_functions' package.
        * Renamed the auto-generation user function module from 'objects' to 'user_functions'.
        * Clean up of the prompt.interpreter module.  This includes the merging of the _auto_generate() method into _setup() and  the clean up of the imports.
        * Created RelaxValListValError and RelaxNoneValListValError for the arg_check.is_val_or_list() function.
        * The prompt UI can now handle the user function argument type of 'val_or_list'.
        * Eliminated the try logic in the arg_check is_*() functions as the raise_error flag can now be used instead.
        * Created the arg_check.is_val_or_list() function for the value.set user function.  The value argument of this user function is now classified as a 'val_or_list' object, hence this is_val_or_list() replaces the use of is_str_or_num_or_str_num_list().
        * Clean up of the prompt package __init__ module.
        * Converted the vmd user functions to the auto-generation design.
        * Eliminated the view user function as this is ancient dead code.  This user function has essentially remained the same as when it was introduced at r788 back in the 0.3 relax line in October 2003!  It has never actually performed any function and has somehow managed to survive in the source tree unnoticed.
        * Converted the value user functions to the auto-generation design.
        * The auto-generated GUI user functions can now handle the 'val_list' argument type.  This is needed for the value.set user function whereby the 'value' argument can be almost anything,either as a single float, int, str, None, etc or as a list.
        * Converted the temperature user function to the auto-generation design.
        * Converted the sys_info user function to the auto-generation design.
        * Converted the structure user functions to the auto-generation design.
        * Float and int numpy arrays and matrices are now supported for GUI user function arguments.
        * Converted the spin user functions to the auto-generation design.
        * The can_be_none value is now propagated into the Combo_list GUI element.
        * The can_be_none argument is now propagated and stored in the Sequence and Sequence_2D GUI elements.  Some debugging print outs have also been removed.
        * Converted the spectrum user functions to the auto-generation design.
        * Added the spectrum.integration_points user function back end so that the auto-generated class can work.  This raises a RelaxImplementError as this is not implemented, but allows the front end to be accessible.
        * Renamed the results.read and results.write user function 'directory' argument to 'dir'.  This in both the front and back ends.
        * Shifted the free_file_format GUI element into its own class.  The wizard page free_file_format() method for generating the GUI element has been shifted into the components.free_file_format.Free_file_format class.
        * Redesigned the free file format window.  The settings module has been renamed to components.free_file_format, as it simply contains the free file format window.  This renaming is in preparation for shifting all of the free file format code into this module to create a special GUI element object for it, rather than being part of the wizard page code base.  The Base_window code has been merged into the Free_file_format_window code, as no other windows use it any more.
        * Eliminated the ancient unused load_sequence() GUI element.  This was part of the settings menu in the original version of the GUI, but now has no purpose.
        * Converted the sequence user functions to the auto-generation design.
        * The model_selection user function now defaults to AIC.
        * Converted the results user functions to the auto-generation design.
        * The reset user function is now called in synchronous mode in the GUI.
        * The user function 'gui_sync' attribute is now passed all the way into the GUI user function objects.
        * The Uf_container now has the 'gui_sync' variable for switching between asynchronous and synchronous operation.
        * Converted the reset user function to the auto-generation design.  A fast and dirty wizard graphic was also added for the user function.
        * Converted the residue user functions to the auto-generation design.
        * Created an icon for the relax_fit user function class.
        * Converted the relax_fit user functions to the auto-generation design.
        * Converted the rdc user functions to the auto-generation design.
        * Removed the old __docformat__ module variable.
        * Converted the pcs user functions to the auto-generation design.
        * Read only arguments as combo boxes can now be set to None, if allowed, in the GUI user functions.  The empty string and None are prepended to the combo box choices and data respectively.
        * Improved the titles of the Sequence and Sequence_2D GUI element for the user functions.  The 'desc_short' user function argument property is now used to create the title rather than the 'name' value.
        * The Sequence and Sequence_2D GUI elements can now handle fixed sized sequences.  When the 'dim' Uf_container.add_keyarg() argument is set, then the 'Add' and 'Delete all' buttons are turned off, the ListCtrl sizes are pre-made, and their SetValue() methods no longer append to the list.  This will allow for better user editing of points, vectors, and matrices.
        * Converted the 'size' user function argument argument to 'dim'.  The name 'dim' better reflects what this is.
        * Absorbed the user function argument argument 'dim' into 'size'.  This is only used by one user function, structure.rotate, which has not been converted to the auto-generation design yet.  The size argument is perfectly suitable for specifying the matrix dimensions.
        * The Sequence and Sequence_2D wizard page GUI element buttons now have a tooltip.
        * The paramag user functions are now using the align_tensor icons and wizard graphics.
        * Converted the paramag.centre user function to the auto-generation design.
        * The n_state_model user function menus now use icons.
        * Created a set of basic icons for the N-state model user functions.
        * Improved the PyMOL ray-traced n_state_model wizard graphic by ray-tracing to 1000x1400 and shrinking.
        * Created a wizard graphic for the n_state_model user functions.
        * Converted the n_state_model user functions to the auto-generation design.  Some of the documentation was updated as it was incorrect.
        * The integer user function GUI elements which can be None now are simply set to a wx.TextCtrl.  The wx.SpinCtrl used previously was incorrect, as a wx.SpinCtrl only handles integers, always defaulting to the minimum of the control.  Therefore the can_be_none user function argument argument is now propagated into the wizard page Value, Sequence and Sequence_2D elements (though they are not functional in the Sequence* classes yet).
        * The wx.SpinCtrl used in the Value wizard page element is now fail-safe.  The code now catches min and max values of None, and does not set the initial value so that a default value of None does not break the wx element.
        * The min and max arguments now default to 0 and 1000 for the Uf_container.add_keyarg() method.
        * Improved the frame_order relax icons.
        * Increased the content of icons in the auto-generated user function menus.
        * Improved the relax noe icons by modifying the wizard SVG file.
        * Converted the noe user functions to the auto-generation design.  The noe wizard graphic has been converted into icons for the menus.
        * Created the generic_fns.spectrum.get_ids() function for returning all current spectrum IDs.  This will be used by the noe.read_intensities user function.
        * Increased the icon content in the auto-generated user function menu.
        * Added the archive-extract Oxygen icon.
        * Added the document-edit Oxygen icons.
        * Added all sizes of the dialog-ok and dialog-ok-apply Oxygen icons.
        * The user function arguments can now have minimum and maximum values for integers specified.  The min and max arguments can now be given,and these are then propagated all the way to the GUI elements.  For the Sequence and Sequence_2D elements this has no effect yet as they do not implement wx.SpinCtrl elements.
        * Eliminated the 'prune' argument to the monte_carlo.error_analysis user function.  This will never be used again, and might tempt some users into changing the value and damaging their analysis!
        * Created a wizard graphic for the monte_carlo user functions from the oxygen 'actions/roll' icon.
        * Converted the monte_carlo user functions to the auto-generation design.
        * Added the 'roll' Oxygen icon and a blue coloured version for use in the monte_carlo menus.
        * Created an icon representing frequency.  This is being used by a number of user functions and classes.
        * Created an icons for the jw_mapping user function class.
        * The model-free user function class now has a menu icon.
        * Converted the molecule user functions to the auto-generation design.
        * Created a basic icon set for the model-free theory.
        * The failure of the user function page on_display() method now prevents the wizard from being displayed.
        * The Uf_page.on_display() method now gracefully handles RelaxErrors from the user function argument iterators.  This now catches the error and uses gui_raise to report to the user.
        * The Uf_container object can now have the 'desc' variable set multiple times.  This allows for molecule user functions where the generic_fns.mol_res_spin.ALLOWED_MOL_TYPES list values are appended to the description.
        * Big improvements for the Combo_list GUI element.  The client data is now set and returned instead of the string values, allowing for more descriptive choices.  The SetValue() method has been implemented.  And floats and ints are now supported as data types.
        * Converted the model_free user functions to the auto-generation design.
        * The consistency_tests.set_frq and jw_mapping.set_frq have been synchronised.  These perform exactly the same purpose, and have been made almost identical.
        * Improved the jw_mapping.set_frq wizard page size.
        * Refinement of the jw_mapping.set_frq user function.  The wizard page now shows a read only ComboBox of the allowed spectrometer frequencies, so that the user does not need to input the exact value.  The descriptions have also been improved.
        * Created the generic_fns.frq.get_values() function for returning a list of unique spectrometer frqs.
        * Improved the relax_data.read user function docs to stress the importance of frequency.
        * Converted the jw_mapping user functions to the auto-generation design.
        * Improvements for the consistency_tests.set_frq user function descriptions.
        * The select.spin and deselect.spin user function arguments spin_id can be None.
        * Removed the leading whitespace from the colour module documentation variables.
        * All leading whitespace is stripped from the docs before creating the auto-generated user function description.  The detection of the end of the table has also been simplified, as stripping the whitespace broke the logic.
        * The simple Value wizard page element default for an integer is now a wx.SpinCtrl.  If the element_type argument is set to 'default' and the data type is integer, then a wx.SpinCtrl will be used.
        * The align_tensor.init param_types argument is now a ComboBox with the choices in the GUI.
        * The generic_fns.grace.get_data_types() function is even more fail proof.  The return_data_desc() call was sometimes raising a RelaxError when not implemented for certain analyses.
        * Converted the grace user functions to the auto-generation design.  This required created the generic_fns.grace.get_data_types() function for returning the data type descriptions and values for the current data pipe.  This is to replace the code in the old grace user function update_parameters() method so that the data type fields are updated according to the analysis.
        * The Value.SetValue() method can handle default values when the list is empty.
        * For the Value wizard page element, the default can be the string or data for a ComboBox now.  If the default is a data value, then this is translated to the string.  This allows the default in the user function data objects to be either the string or data value, removing a source of coding errors.
        * Converted the frq user functions to the auto-generation design.
        * Created icons and wizard graphics for the frame_order user functions.
        * Converted the frame_order user functions to the auto-generation design.
        * Added error checking to the Uf_container to eliminate typo coding mistakes.  This checks that a variable is not set twice (copy and paste error).
        * Converted the fix user function to the auto-generation design.  The object-locked and object-unlocked Oxygen icons have been combined to create a wizard graphic for this user function.
        * Created wizard graphics for the eliminate user function.
        * Converted the eliminate user function to the auto-generation design.
        * Function arguments are now ignored as well in the auto-generated GUI user functions.
        * Created icons and wizard graphics for the auto-generated dx user functions.
        * Converted the dx user functions to the auto-generation design.  Some of the checks at the prompt level had to be shifted into the back end, where they belong.
        * The Value wizard page GUI element can now be set to a wx.SpinCtrl.  This is only allowed for integers.
        * The default file name is now passed all the way into the RelaxFileDialog.  This is for the auto-generated GUI user functions.
        * Improvements to the Selector_dir wizard page GUI element.  The icon is now for a directory open and not file open, the tooltip is also fixed, and the default value is now passed all the way through.
        * The auto-generated user functions and classes are now always alphabetically sorted.  The Uf_object.add_class() and Uf_object.add_uf() method now sort the lists at the end.  The data objects are stored in dictionaries to avoid sorting issues.
        * Created wizard graphics for the select and deselect user function classes.  The spin and spin_grey icons are used for the menus.
        * Converted the select and deselect user functions to the auto-generation design.  The boolean_doc variable has been shifted from the deleted prompt.select module into the generic_fns.selection module, where it belongs.
        * The new icon fetching system is now being used for the relax icons in the menus.
        * The relax Ulysses butterfly icons are now in the icon directory and in all sizes.  The 16x16 icon has also been improved.
        * Shifted all the gui/images graphics into the graphics/misc directory.  This finally brings in all of the graphics into one place.
        * Set the state user function class menu icon to the relax icon.
        * Converted the molmol user function to the auto-generation design.  For this process, the molmol.macro_apply and molmol.macro_write user function colour_start and colour_end arguments had to be split, just as in the pymol user functions.  They previously accepted both a Molmol or X11 colour name or an RGB colour array but are now separate arguments.
        * Converted the pymol_control user function to the auto-generation design.  For this process, the pymol.macro_apply and pymol.macro_write user function colour_start and colour_end arguments had to be split.  They previously accepted both a Molmol or X11 colour name or an RGB colour array.  Now there are separate arguments for the colour name and RGB colour array.
        * The Sequence based wizard page GUI elements now return None if the field is empty.  This was previously returning [] or () to the auto-generated user functions when they were expecting None.
        * The auto-generated user function menu is now correctly sorted.
        * Converted the model_selection user function to the auto-generation design.
        * Added graphics for the model_selection user function.
        * Created icons and wizard graphics for the calc and minimise user functions.
        * Created icons for the grid_search user function.
        * Eliminated the wiz_combo_default and combo_default arguments from the GUI auto-generated user functions.  These are now provided by the 'default' argument.
        * Eliminated the 'wiz_combo_default' user function argument argument.  This argument is duplicative of the 'default' argument.
        * The default value of the user function arguments is now set in the wizard page elements.  This is for the auto-generated user functions.
        * Converted the calc, grid_search and minimise user functions to the auto-generation design.  The minimise user function required a lot of work, as the minimise(*args, *kargs) construct is incompatible with the auto-generation design.  As this is hardly used in the field, everything has been converted to specific keyword arguments.  This will have a side benefit of being easier to understand for a user.  The back end was modified accordingly.
        * The 'additional' sections are now shown before the 'examples' section in the prompt help system.
        * The user functions without a base class are now supported in the prompt, script, and GUI modes.  This is for the auto-generated user functions not stored in a user function class object.
        * The 'num_or_num_list' and 'num_or_num_tuple' argument types are now supported in the GUI.  These are for the auto-generated GUI user functions.  The 'num_or_num_tuple' argument type is used for the diffusion_tensor.init user function, for example.
        * Improvements for the diffusion_tensor.init user function data setup.
        * Converted the diffusion_tensor user functions to the auto-generation design.  The icons and wizard graphics for these user functions has also been created.
        * Created icons and wizard graphics for the palmer user functions.
        * Converted the palmer user functions to the auto-generation design.
        * The auto-generated user function additional documentation is now used by the prompt UI.  The data was not being passed into the prompt user function objects.
        * The additional documentation for the auto-generated user functions is now properly processed in the GUI.
        * Converted the dasha user functions to the auto-generation design.
        * Added support for the directory selection wizard page element for the auto-generated user functions.  This uses the new Selector_dir GUI element.
        * Converted the consistency_tests user functions to the auto-generation design.
        * Converted the angles user functions to the auto-generation design.
        * Converted the bruker user functions to the auto-generation design.
        * Converted all of the state user functions to the auto-generation design.
        * List of lists types are now properly handed by the auto-generated user function in prompt/scripts.
        * Significantly increased the number of icons used in the auto-generated user function menus.
        * Added icons and wizard graphics for the align_tensor user functions.
        * Converted all of the relax_data user functions to the auto-generation design.
        * The buttons of the Selector_file wizard page element now have better tooltips.  The open button now has a tooltip related to opening.  The preview button has the "Preview" tooltip rather than the element_file_sel tooltip, so that the user knows what the button does.
        * The wizard description height is now functional in the auto-generated user functions.  The height_desc argument was being overwritten by the base class Wiz_page.__init__() method.
        * Added support for the free format file settings GUI element to the auto-generated user functions.  The normal argument elements are suppressed if the arg_type arg is set to 'free format', and the free format element will then be added to the end.  The 'data_col' argument is searched for to see if the data elements should be activated.
        * Created the generic_fns.relax_data.get_ids() function for returning all relaxation data IDs.  This is needed for the auto-generated user functions in the GUI.
        * The user function argument type of 'num' is now handled as a float in the auto-generated GUI elements.
        * The wizard height_desc variable can now be set in the auto-generated user functions.  This is via the wizard_height_desc variable.
        * The user function data object add_class() and add_uf() methods now check for uniqueness.  This is to catch coding errors whereby the user function class or name has been duplicated.
        * Removed the now useless 'user_functions.functions' module.
        * The Bmrb.test_bmrb_rw GUI test is now complete and fully uses the new auto-generated user functions.  This test will only pass once all the relevant user functions are converted to the auto-generation design.
        * The 2D sequence arguments of the auto-generated GUI user functions now matches the normal sequence elements.  The String_list_of_lists_window has been converted to Sequence_window_2D which inherits from Sequence_window.  All Python types and sequences supported by the Sequence GUI element are now supported by the Sequence_2D element (which is the old String_list_of_lists).
        * Converted all of the align_tensor user functions to the auto-generation design.
        * Merged all of the sequence wizard page GUI elements into one.  This is to significantly simplify the code.
        * Added GUI conversion functions for tuples.
        * Better checking of the contents of the GUI element by Value.GetValue().
        * Merged the Base_value, Float, Integer, and String wizard elements together into the single Value class.  This simplifies the code, as the differences between them was very minor.
        * Floats and tuples of numbers are now supported by the user function GUI argument elements.
        * The align_tensor.display user function backend argument is now a keyword argument.  This is for supporting the auto-generated user functions.
        * Created the align_tensor.get_ids() method for use in the GUI wizards.  This will be required for the auto-generated user function GUI front ends.
        * The pipe.copy pipe_from wizard element is now read only.
        * The user function intro is now printed out before the argument checking.  This is for better user feedback.
        * The pipe editor window now uses the auto-generated pipe user function GUI objects.
        * The user function backend and title values are now enforced.  If these are not set, a RelaxError is thrown.  This should avoid fatal coding accidents.
        * Converted all of the brmb user functions to the new user function design.
        * All of the exp_info user functions now check for the presence of the cdp.  This allows for better user feedback.
        * The default list element now defaults to read only, whereas the Combo_list object defaults to not read only.
        * The List objects can now handle bad user input.
        * The wiz_read_only flag now defaults to None, to allow the GUI elements to decide the best option.
        * The read_only flag now is fully functional in the String_list wizard page element.
        * The wiz_read_only user function flag is now propagated into the String_list GUI elements.
        * The Combo_list GUI element can now handle an initial size of None, converting this to 1.
        * The list wizard GUI elements no longer show empty lists.
        * The Base_value class can now accept the element_type argument value of 'default'.  This will then use the TextCtrl.
        * The add_keyarg() wiz_element_type argument default is now 'default' to be able to handle all element types.  The previous default of 'text' for a TextCtrl was causing failures with certain wizard GUI elements.
        * The relax controller is now shown for the auto-generated GUI user functions if 'display' is set.  This is the 'display' variable in the user function data store.  This allows all the user functions which print to STDOUT to pop up the controller in front of the user, so they see the result.
        * The user function data structure now accepts the 'display' boolean variable.  This is used to indicate that a user function would like to display some output to STDOUT.
        * All of the user function argument arguments are now handled by the add_keyarg() method.
        * All of the argument checking types are now supported for the auto-generated user functions.  This covers every type of arg_check.is_*() function used in relax.
        * Boolean argument types are now supported by the auto-generated GUI user functions.  The Selector_bool object and element_bool() wizard page method have been written for this.
        * The can_be_none user function argument argument is now used.  This is needed for proper argument checking in the auto-generated user functions.
        * The wizard page GetValue() method now returns None if the corresponding key is missing.  This is needed for the directory arguments as these are not shown in the GUI.
        * Improvements to the element_file_sel() wizard page method.
        * Created the special Selector_file wizard element object.  This is modelled on the file_selector() wizard page method.
        * Created the element_dir_sel() and element_file_sel() wizard page methods.  This will require the selector objects to be written.
        * The auto-generated GUI user functions objects now support the special UI types.  This includes the file and dir selection dialogs, and skipping the dir arguments.
        * The arg_type argument for the auto-generated user functions is now accepted.  This will be used to allow special UI elements to be used for the argument, for example a file selection dialog.
        * Integers and string list of lists are now accepted by the auto-generated GUI user functions.
        * Expanded the wizard page element_int() method to accept all the arguments of element_string().  All these arguments will be handled properly by the Integer class as this derives from Base_value.
        * The list_titles argument is now accepted for the auto-generated user functions.  This is for a list of lists, and are the titles for the lists.
        * The auto-generated Uf_page.add_contents() method now raises a RelaxError if the Python type is unknown.
        * The menu_text variable now defaults to '' so that the GUI does not die if this is not set.
        * Removed the wiz_desc arguments from the pipe user functions.
        * Eliminated the wiz_desc argument in the auto-generated user functions.  Now the desc_short argument will be used instead for the GUI user function elements.
        * The desc_short rather than wiz_desc argument is now used for the GUI elements.  This is for the auto-generated user functions.
        * The wiz_desc argument is no longer compulsory for the auto-generated user functions.  This will eventually be merged with the desc_short argument anyway.
        * The GUI test execute_uf() base method now operates with the auto-generated user functions.
        * Advancements for the auto-generated GUI user functions.  String list GUI elements are now supported.  The wizard element are now updated on display, allowing for example the current set of data pipes to be displayed in the ComboBoxes of the pipe user functions.
        * The List and Combo_list class now have ResetChoices() methods.  This allows these elements to fit with the auto-generated GUI user functions.
        * Big set of changes enabling the auto-generation of the GUI user function front ends.  This will create user function objects which are bound to the menu items, and the user function page objects automatically from the user_function data object.  The pipe user functions have been updated to supply the needed data, and additional arguments have been added to the Uf_container.add_keyarg() method.  The Uf_container object can now accept additional wizard related variables.
        * The graphics package image variables are now imported into the paths module.  This is for backwards compatibility with the old user function pages.
        * Shifted a number of the image path variables from the gui.paths module to the graphics package.
        * The user function GUI menu item is now being auto-generated.  This will require future work to support user functions not within a user function class.
        * The graphics.fetch_icon() function now returns None if no icon is specified.
        * Created the graphics.fetch_icon() function for a better API for the icon paths.  This will eventually replace the gui.paths module.
        * The graphics directory has been converted into a Python package.  This will be used to store special functions related to graphics manipulation, retrieval, etc.
        * Renamed the gui.user_functions package to gui.uf_pages to avoid import clashes.  This package was clashing with the base user_functions package, breaking imports everywhere.
        * Started to write the auto-generated user function GUI menu.
        * Created methods for returning user function and class data objects from the user function data object.  These are called get_class() and get_uf().
        * The auto-generated prompt user function front end objects are now executable.  The uf.backend variable is now the executable Python object.  The pipe user function class has been updated for the uf.backend change.
        * Implemented the missing back end of the pipe.current user function!
        * Expanded and fixed the argument checking for the prompt auto-generated user function front ends.
        * The auto-generated prompt user function front ends now convert arguments to keyword arguments.  This is important as a keyword argument can be supplied without the keyword in Python.
        * Removed the last reference to the eliminated Exec_info prompt object.
        * Clean up of the prompt intro strings for the auto-generated user functions.
        * The prompt intro strings are now created for the auto-generated user functions.
        * Absorbed the Exec_info prompt object into the relax status singleton and eliminated it.  The prompt strings are now prompt.base_class module variables, and the current ones are stored in the status object.  The user function intro flag is now stored in status.prompt_intro.  The prompt_colour_on() and prompt_colour_off() methods are now methods of the interpreter class.  Now that the Exec_info class no longer exists, the Basic_class class has also no purpose and has been eliminated.
        * The prompt help system now uses bold text for the title line and all subtitles.  The subtitle underlines are now not used, but the ability to underline is retained.
        * The relax prompt help system is now being passed through pydoc.pager to page the text.  This system will be used by the auto-generated user functions.
        * The documentation for the auto-generated user functions is now being created.  This is stored in the __relax_help__ string, and mimics the old system, reusing many of the base functions.  All the user function data required for the prompt interface is now being passed in to the object.
        * Renamed the private _args variable to the non-private kargs.
        * The user function object now has a __repr__ method to give better feedback to the user.
        * Primitive auto-generation of the user functions.  This simply creates an object for the user function, but it is not callable yet or uses any of the user function data.
        * Modified the pipe user function class description.
        * The __description__ attribute from the old help system is now supported in the auto-generated classes.
        * The new auto-generated user function classes now fit into the prompt help system.
        * Documented the prompt-based help system _Helper.__call__() method.
        * The auto-generated user class object now accepts the desc argument and stores it for use in the help system.
        * Added a __repr__ method to the user function class objects for presenting a better message to users.
        * Added the prompt.objects module which contains the user function auto-generation objects.
        * The interpreter now auto-generates the user function classes.
        * Modified the Class_container class to be more like the Uf_container class.
        * Added two iterator methods for looping over the user functions and classes.  These are class_loop() and uf_loop().
        * The user function container arguments variable is now private and modifiable.  It needs to be modifiable so the __init__ method can initialise it.
        * Clean up of the pipe module (removal of useless imports and syntax fixes).
        * The pipe module is now imported in the __init__ module to set up the data structures.
        * The user function data object is now imported into the interpreter.
        * Added the desc_short argument to the add_keyarg() user function container method.  This argument is used in RelaxErrors for when incorrect parameter are supplied.
        * Converted the entire of the 'pipe' module to populate the user function data structure.
        * Big improvements to the user function data container.  The changes are:  More attributes are now accepted; now only allowed attributes can be modified, to prevent programming errors; docstring improvements; and more keyword argument data can be input.
        * Shifted a check from the pipe.create front end to the back end.  Tests do not belong in the front end!  And this is not compatible with the new user function design.
        * Removed the pipe user function class import and instantiation from the interpreter object.  This will be re-introduced later with a new auto-generation architecture, taking the info from the user_function data object.
        * Shifted the pipe module from the prompt to user_functions package.  This is in preparation for the full conversion of this user function class into the new auto-generation design.
        * Added a unit test for the contents of the user_function package.
        * The unit test _user_functions package is now actually a package.
        * Created a unit test package for the user_function package.
        * Shifted the Uf_info singleton into the new user_functions.data module.  This will avoid a lot of circular imports.
        * Created a module for setting up all of the user function data.  This is just a test, so probably will not be permanent.
        * Created the Uf_info singleton class for holding all of user function data.
        * Created a number of special objects for the user function data storage.
        * Created the user_functions package.
        * Added checks for the proton frq for the relax_data.read and relax_data.back_calc user functions - if the frequency is not exact or is less than 1 MHz, warnings are now given to the user.
        * Made the bond vector extraction print out from structure.vectors more informative.
        * Created a sample script for BMRB data deposition.
        * The relax data store is_empty() method now only prints to STDERR if the verbosity flag is set.
        * Changed the behaviour of the generate_spin_id() and generate_spin_id_data_array() functions.  This is a large change affecting many parts of the code base.  The problem that this solves is the incorrect usage of the '&' character in spin IDs, tripping up on the powerful Selection object of Chris MacRaild.  For example, the spin ID ':2&:Glu' cannot be correctly handled.  This actually matches all residues with the number 2, and all residues with the name 'Glu'.
        * The scons 'clean' target now removes *.pyo files as well.


    Bugfixes:
        * Fixes for the bmrb.write backend - the generic_fns.exp_info module should be used rather than the cdp.  The abstraction via the generic_fns.exp_info module is needed to make sure all the relevant current data pipe structures are set up.
        * Fix for the bmrb.display user function - this user function never worked as pystarlib expects a file path as a string, but a modification of pystarlib fixes this.
        * Fix for the model-free about dialog - the fonts for the different titles can now be set.  The new font.roman_font_18 has been added, and the about dialog draw_title() method now takes the alt_font arg for specifying an alternative font.
        * Bug fix for the model-free specific analysis duplicate_data() method - the cdp.exp_info should be skipped.  This was not picked up before as this structure is normally non-existent during the analysis.
        * Fix for the Bruker system tests - the NMR proton frequency is in Hz, not MHz.
        * Fix for the GUI for when a script is launched from the command line - the analysis tabs are now updated at the end of the __init__() method, and the ds.relax_gui data store object is no longer overwritten if it already exists.
        * Bug fix for running a script when launching the GUI.  This was completely failing but now the script is executed prior to the launching of the GUI.
        * Bug fix for the generic_fns.spectrum.replicated_ids() function for when no replicates exist.  This will now return an empty list instead of an error being raised.
        * Fix for the spectrum.read user function - a RelaxError is now raised if the file name is not given.  This is important for the GUI to prevent unintelligible errors to be presented to the user.
        * Fix for the experimental information in the relax data store - the information can now be reset.
        * Bug fix - the 'relax --version' print out now works from any directory.  This was only working if relax was being run from the installation directory!
        * Fix for the prompt and script UI user function intro printouts.  This text is no longer passed through the format_text() function which has problems with newline characters.
        * Fixes for the GUI tests tearDown() method.  All wx events are now flushed before the deletion of GUI elements.
        * The pipe.delete user function now operates synchronously in the GUI to avoid the GUI blowing up!
        * The user function pages are now registered and unregistered with the 'gui_uf' observer object.  This allows the ComboBox args to be properly updated with asynchronous user function calls.  The old update method suffered from racing and hence often updated before the user function had executed.  Now the on_display() method registers the GUI user function page update_args() method, and the on_next() method unregisters it, allowing the observer to update the page only when it is visible to the user.
        * Fix for the GUI tests - the ds.tmpfile string is now being created by the base setUp() method.  This is needed to stop files from being created within the relax directory tree.
        * Bug fix for the model-free specific analysis - the Dr diffusion tensor parameter is now defined.
        * Fix for the arg_check.is_float_matrix() function for rank-1 arrays.  The function failed on lists of Python values, for example a list of bools.  An additional check has been added to make sure that the list elements are also lists.
        * The delete all analysis method now does what it warns and resets relax at the end.
        * Fix for the model-free GUI auto-analysis test under certain conditions.  The spin viewer window was loading the spins asynchronously, but the subsequent relaxation data loading was synchronous.  If a previous GUI test failed this would often trigger a racing condition.
        * Mac OS X bug fix for the non-read only ComboBox GUI input elements.  This is for the Value and Combo_list GUI input elements.  The problem was two-fold.  First the convert_to_gui() call was required to convert the value to a unicode string, as a normal string will be not be set via the ComboBox.SetValue() method.  Secondly old selections need to be turned off.  On other operating systems, the SetValue() call will reset this - but not on Macs.
        * Mac OS X bug fixes for the GUI ComboBox input elements.  The ComboBox.GetClientData() method on Mac OS X fails if the ComboBox.GetSelection() method returns -1 (or wx.NOT_FOUND).
        * Bug fix for all of the specific analysis code.  The SPIN_PARAM and GLOBAL_PARAM structures are now initialised within the __init__() methods rather than being class variables.  This bug was only uncovered by the auto-generated user functions.  The problem with them being class variables of the base class is that the objects are then the same for all specific analyses.
        * Fixed the N-state model description so that it is no longer about domain motions.  This stands out in the GUI when creating data pipes!
        * The GUI user function on_execute() method no longer shows the controller in test suite mode.  The controller Raise() method was being called at the end of the method, without checking status.show_gui.
        * Fix for the pipe editor - this window is now the parent for the user functions it calls.  Therefore the pipe editor no longer disappears behind the main relax window.
        * Fix for two of the arg_check.is_*() fns - the individual elements were incorrectly checked.
        * Bug fix for the Combo_list.GetValue() method - it can now handle no user input cleanly.
        * Fix for the Analysis_controller.on_page_changed() method for reset events.  The relax data store now always has a ds.relax_gui object!
        * Fix for the post_reset() method of the Analysis_controller object.  This unregisters all the analyses from the observer objects, and calls the set_init_state() method only once all analysis pages are deleted.  This in combination with the synchronous reset user function calling prevents the GUI from blowing up!
        * Fix for the gui.misc.gui_to_tuple() function.  This was failing in many cases, especially where the value is not a tuple to start with.
        * Bug fix for the bruker.read user function for reading Bruker Dynamics Centre files - the spectrometer frequency needs to be converted from MHz to Hz.
        * Bug fix for the loading of the molecule name and type from relax state or results files.  The str() builtin function is now used to convert the string from unicode to a normal string.  This is needed as u'My mol' != 'My mol', breaking a number of tests.
        * The relax_data.delete user function is now finally properly implemented (bug #19785, https://gna.org/bugs/?19785).
        * The model-free minimisation is now checking for multiple vectors per spin, and raises a RelaxError.
        * Fix for the relax controller SplitIO() setup for logging and teeing modes.  The SplitIO() usage is now disabled for the test suite.  This prevents a doubling of the print outs in the GUI tests.  The problem was introduced at r15843 with the accommodation for the logging and teeing modes with the GUI.
        * Created a system test Mol_res_spin.test_residue_delete() demonstrating a failure of the user function - deleting the first residue removes the entire sequence.
        * Fixes for most of the structure user functions - the pipe check is now performed at the start.



Version 1.3.16
(11 May 2012, from /1.3)
http://svn.gna.org/svn/relax/tags/1.3.16

    Features:
        * The scons 'install' target now creates both *.pyc and *.pyo files during installation - this should result in faster relax startup times.
        * The test suite now passes on the Fink relax installation on Mac OS X as the ancient and very dead PyXML module is now being detected and worked around.
        * Renamed the 'pdc' user function class to 'bruker' and removed all references to 'protein' - this is due to the Bruker absorption of the Protein Dynamics Centre into the Bruker Dynamics Centre announced at https://mail.gna.org/public/relax-users/2012-04/msg00011.html (Message-id: <4F7AE13B.6010309@bruker.de>) by Dr. Klaus-Peter Neidig (peter dott neidig att bruker-biospin dott de).
        * Updates and improvements throughout the relax user manual.
        * Added a new section to the introduction chapter of the user manual for Gary Thompson's multi-processor framework.
        * Added screenshots and descriptions of the graphical user interface (GUI) to the introduction and all of the analysis chapters of the relax user manual.
        * The GUI and logging/teeing modes are now compatible with each other.
        * Expansion and completion of the model-free chapter of the relax user manual.


    Changes:
        * Improved debugging of the observers in the status singleton object.
        * Changed the behaviour of the arg_check module so that the functions can return answers.
        * The Bmrb.test_bmrb_rw GUI test now uses the base execute_uf() method for the pipe.create call - this is part of the simplification of the user function interfaces.
        * A number of the pipe GUI user function front ends now use the wizard page element_*() methods to simplify the code base.
        * The wizard page element_string_list() method can now create the special Combo_list objects.
        * Created the wizard page ResetChoices() method for resetting the list of values in a ComboBox.
        * Created a Clear() wizard page method for clearing a specific GUI element.
        * The wizard page element_string() GUI element creator read_only flag now defaults to False.
        * The read_only=True flag to wizard_elements.Base_value now sets a TextCtrl to the background colour.
        * The wizard_elements.Base_value.SetValue() method now works properly with the ComboBox.
        * The wizard_elements.Base_value class now can set the element to be read only.
        * Created generic_fns.pipes.PIPE_DESC_LIST which is the PIPE_DESC as a list, sorted by VALID_TYPES (to be used in the GUI user functions).
        * Better ComboBox support in wizard_elements.Base_value class - now strings and data are separate (if the data is supplied), and the GetValue() method now returns the client data rather than the string value.
        * Modified the wizard_elements.Base_value base GUI element class to handle combo boxes.
        * The Bmrb.test_bmrb_rw GUI test now uses the new execute_uf() method for the bmrb.citation user function.
        * Created the GUI test base method execute_uf() for executing a user function.
        * The bmrb.citation GUI user function now uses the new wizard page element_*() methods for the GUI elements.
        * Created a new wizard element for inputting integers.
        * Created a new wizard element for inputting strings.
        * Created the Bmrb.test_bmrb_rw GUI test.

Screenshots of all the GUI windows and analyses have been added to prettify the chapter, and the text for the GUI has been rewritten for the new GUI design.
        * Added a number of GUI screenshots for use in the relax user manual - these were taken from http://www.nmr-relax.com/screenshots.html.
        * Added colons to all entries of the abbreviation chapter in the relax user manual.
        * Updated and completed the installation chapter of the relax user manual - a lot of the text was 4-6 years out of date.

        * The relax_fit.py sample script deselect.read user function now has all columns specified (bug #19717, http://gna.org/bugs/?19717).
        * Improved the error message system for the spin ID matching multiple spins (bug #19717, http://gna.org/bugs/?19717).
        * Fix for the test suite GUI tests - one of the state system tests was removing the frame order analysis from the generic_fns.pipes.VALID_TYPES list with a pop() call.
        * Simplified the wizard_elements.Base_value ResetChoices() method - this is an attempt to fix some racing conditions under wxGTK, triggered in the test suite.
        * Fix for the bmrb.citation user function documentation.
        * The Mf.test_write_results system test now checks for the ancient PyXML - this ancient version from 2004 which should be eliminated, if installed, causes the toprettyxml() changes in Python 2.7.3 to be overridden.
        * The alignment tensor user functions can now all handle the situation whereby no tensors exist.
        * Fix for the scons 'install' target for the byte-compilation of the *.pyc files.
        * Fix for the chi2 references in the maths chapter of the relax user manual.
        * Fix for the ANSI escape sequences for colouring text for when an isatty() method does not exist.

Version 1.3.15
(25 April 2012, from /1.3)
http://svn.gna.org/svn/relax/tags/1.3.15

    Features:
        * Large improvements to the HTML user manual (http://www.nmr-relax.com/manual/index.html).
        * The full test suite, including GUI tests, can now be run successfully from the GUI.
        * The Mac OS X binary distribution file now supports Leopard, Snow Leopard and Lion as well as the PPC, i386 and x86_64 CPU architectures.
        * The prompt and script output to a terminal is now coloured.
        * Faster program startup by only importing the test suite and GUI packages if they are actually needed.
        * Files selected via the GUI user functions can now be previewed.
        * Redesign of the spin loading wizard of the spin viewer window to be more intuitive.
        * Expansion of the system information print out.
        * Advances in the multi-processor framework including the pre-sending of data to slaves.
        * Support for wxPython 2.9.


    Changes:
        * Changed all of the maths in the HTML user manual page titles, the latexonly and htmlonly environments are now being used to produce different section titles with and without maths respectively.
        * The latex2html configuration script now allows for more maths in the HTML user manual with the HTML_VERSION math extension.
        * The section numbers are now removed from the HTML user manual pages to allow for more static webpages for the user functions which do not disappear as new user functions are added.
        * The title page of the HTML user manual has been renamed to "The relax user manual".
        * Updated the ancient COMMITTERS file which has not been changed in over 4 years!
        * The pipe editor window is no longer centred, now matching the behaviour all other windows.
        * All open relax windows are now closed prior to running the test suite within the GUI.
        * Exiting the GUI now only warns about data loss only if there is data to loose.
        * The relax controller can now not be closed while the test suite is running.
        * During the GUI tests from the GUI, the relax controller is now modal preventing users from interfering with the tests.
        * The relax controller now stays on top of all windows when the GUI tests are being run improving the running of the tests on Mac OS X and MS Windows.
        * The GUI tests now work in the GUI thanks to a lot of GUI black magic.  The tests' tearDown() method now carefully deconstructs the GUI element prior to the next test being run.  In the normal 'relax --gui-test' mode, the GUI object is destroyed and recreated for each test however, when run from the GUI, the GUI object is always there and must remain intact.  The deconstruction includes deletion of each analysis tab and selective destruction of all non-main windows (excluding the controller which shows the test suite progress).  The relax data store GUI object is also reconstructed in the tearDown() method, and all wx events flushed at the very end to prevent clashes with the next GUI test.
        * The relax mode (i.e. prompt, script, GUI, test suite, etc.) is now stored in the status object - this is used to activate and deactivate certain parts of the GUI tests within the GUI and normal test suite modes.
        * The ds.relax_gui GUI data object is now a permanent feature of the relax data store.
        * The 'Tools->Test suite' menu item has been converted into a sub-menu with entries for running all tests or the individual test categories.
        * Created the _det_install_path() status singleton method for better determining the install path - this is used for the Mac OS X applications whereby the current logic of using sys.path[0] fails miserably!
        * Prepared the multi-processor package for the import mechanisms of Python 3 - this new mechanism is present in Python 2.7 now, and the code falls back to the old method when not present.
        * Complete redesign of the py2app setup.py script for building Mac OS X applications.  The script has been converted into a class called Setup which performs all the actions.  All files, source or otherwise, are now stated as data files to be included in relax.app/Contents/Resources.  All relax modules are specified by the py2app 'includes' option so that they are forced to all be included within the relax.app/Contents/Resources/lib/python2.X/site-packages.zip file as *.pyc files.
        * The py2app part of the setup.py script now throws a RelaxError if the setuptools module is missing.
        * Added the relax prompt icon to the main GUI window toolbar.
        * Added the larger sized application-x-executable-script Oxygen icons.
        * Created the 'ansi' module containing the terminal colouring ANSI escape sequences.
        * The test suite is now only imported in the test modes of operation - this should speed up program initialisation.
        * The import of the gui package now only occurs in GUI mode - this will speed up the program start up.
        * The script print out in scripting mode is now in cyan if sys.stdout is a TTY.
        * ANSI escape characters are now turned off forcibly when in GUI mode.
        * The sys.std*.isatty() methods are being used to determine if text output should be coloured.
        * All RelaxWarnings are now coloured yellow when printed to a TTY.
        * All RelaxErrors are now coloured red when printed to a TTY.
        * The relax prompts will be coloured blue when printed to a TTY.
        * The GUI analyses delete_all() method now unregisters all observer methods prior to deletion.
        * Created observer_register() for all GUI analyses for method registration and unregistration - this method allows for external calls to observer_register() to pre-remove the methods from the observer objects.
        * Added debugging printouts to the delete_all() analysis method.
        * More advanced debugging printouts for the delete_analysis() method.
        * Added some heavy debugging code to the GUI analysis delete_analysis() method.
        * Increased the size of the model-free model change warning dialog for wxPython 2.9 on GNU/Linux.
        * The file selection wizard GUI element now has the preview button turned on by default.
        * Double clicking on a file in the results view window now opens it.
        * Added a file preview button for the spectrum.read_intensities user function GUI page.
        * Added a file preview button to the file selection GUI element of the wizards.
        * Increased the size of the incomplete set up dialogs for wxPython 2.9 on GNU/Linux.
        * Added the document-preview.png Oxygen icons.
        * Increased the loading state warning dialog size - this is to accommodate for larger text on wxPython 2.9 on GNU/Linux with GTK.
        * Improved the spin data deletion messages from the spin viewer window.
        * Increased the dialog heights for the deletion of spin data via the spin viewer window.
        * Improved the user feedback during a state save by just sleeping a little to show the busy cursor.
        * Modified the spin loading wizard so that preloaded structures are the default.
        * The maths_fns.relax_fit module is now stored in the dep_check module for the info print out.
        * Added the structure.read_xyz user function to the menus.
        * Created the Tools->System Information menu entry, which is simply the sys_info user function front end.
        * Created the GUI front end to the structure.read_xyz user function.
        * The relax controller now accepts Ctrl-A to select all text.
        * The relax controller now shows the relax intro text to mimic the prompt/scripting modes.
        * Introduced the empty() method into the structure API to check if structural data is loaded - this will be used in the spin loading wizard of the spin viewer window.
        * Converted the structure.read_xyz user function front end to the new design.
        * Improved details of relax and the compiled C modules from the info print out.
        * Created a dictionary object containing wxPython version info within the status singleton object - this is being used to construct the Mac dock icon, when the Carbon and Cocoa builds and not GTK are being used.
        * Updated the multi-processor package __all__ list to allow the relax unit tests to pass.
        * Added a document describing how to build a 3-way (i386, pcc, x86_64) Mac OS X Python framework.
        * Added a script which is used to validate the binary architecture of Mac OS X Frameworks.
        * Improved the relax info print out for the installed python packages - this now shows more information for the wxPython version, and formats the output based on maximum widths to handle different situations.
        * Removed the ppc64 build target for the relax C modules on Mac OS X - this architecture is not supported by the recent Xcode frameworks, so it has been dropped.
        * The scons binary_dist target on Mac OS X can now overwrite a pre-existing DMG file.
        * Added some epydoc @attention fields to the multi-processor API.
        * Created the fetch_data_store() multi-processor API function - this simply returns the data store of the same processor as the calling code.
        * The 2nd test implementation's slave command now uses the fetch_data() API function - this is to obtain the invariant data pre-sent by the master to the slaves.
        * Renamed the multi-processor API data_fetch() function to fetch_data(), and implemented it.
        * Renamed data_upload() to send_data_to_slaves() and made it more specific.
        * The multi-processor data_fetch() API function is now used to obtain the total_length variable.
        * Shifted the self.threaded_result_processing flag into the base Processor class where it belongs.
        * Clean up and completion of the TODO for the Processor.assert_on_master() method.  The Processor.assert_on_master() method has been created and calls raise_unimplemented().  The Multi_processor.assert_on_master() method has been shifted to Mpi4py_processor.assert_on_master(), as that method's error message is MPI specific.  The empty Uni_processor.assert_on_master() method has been added to allow that fabric to work.
        * Spun out all of the results queue objects into their own module.  This completes another set of TODOs by removing these queue objects from any fabric level.  They can now be imported and used by any fabric level (Processor, Multi_processor, Mpi4py_processor, Uni_processor, etc.).
        * Shifted the run_command_queue() and run_queue() methods from the Multi_processor to Processor class.
        * The multi/test_implementation2.py script can now be run in uni-processor mode.
        * The multi/test_implementation2.py script now properly uses pre-send data in the slave calculations.
        * Partially implemented the Processor.data_update() method.
        * Created the special command object Slave_storage_command for transferring data to slaves - this command currently has two special methods:  add(), used by the master processor to add data to the command for transfer; and clear(), used by the slave (via run()) or the master to clear out all data.
        * Split the multi.commands module into two - the slave commands and result commands.
        * Removed the Mpi_processor.data_upload() method as this will be performed at the Processor level.
        * Shifted all of the processor command objects into the multi.commands module.  The other multi.api module objects have been shifted into the multi.misc module.
        * The multi-processor package now allows sys.exit() calls within the master processor.
        * Removed a number of sys.exit() calls from different relax modes.  The return call is used rather than sys.exit() to exit the main run() method.  These were not needed and it allows the 'version', 'info', and 'gui' modes to play better with the multi-processor package when using mpi4py.
        * Shifted the mpi4py processor module functions broadcast_command() and ditch_all_results() into the class - these have been turned into private methods.
        * Redesigned how the multi-processor package terminates program execution - the Processor.exit() method has been introduced to perform this action.
        * Spelling fix for a number of the processor method names.
        * Fully documented the Processor.run() method via comments.
        * Eliminated the unused Set_processor_property_command multi-processor class.
        * Eliminated the unused Get_name_command multi-processor class.
        * Shifted the Multi_processor.run() method up a level to Processor.run() - this completes one of the TODOs, and will be needed to avoid code duplication for handling the new data_upload() and data_fetch() API methods.
        * Eliminated the completely unused create_slaves() Processor method.
        * The processor instances now have a data storage container - this will be used by the data_upload() and data_fetch() API methods.
        * Implemented the mpi4py processor fabric data_upload() method.
        * Updated the second multi-processor test implementation to use the new data_upload() API function.
        * The multi.data_upload() API function now forwards the call to the Processor classes.
        * Clean up of the Multi_processor.run_command_queue() method.


    Bugfixes:
        * Fix for the about dialogs in the GUI when combined with a scrolling window (this is only a problem for the wxPython 2.9 series).
        * Fix for the fetch_docstrings.py script used for the user manual creation - the number of \linebreak[0] commands inserted was far too great.
        * In generating the HTML user manual, the ignore_commands function is now being used to force latex2html to ignore \linebreak[0] commands as these were previously putting the text '[0]' throughout all the HTML pages.
        * For the HTML user manual, the document splitting has been restored to a split depth of 5 - this had been changed to make the main chapters of the text more readable, but the user function HTML page is now far, far too long and is a massive strain on browsers.
        * The Mf.test_write_results system test now works with the newer Python 2.7.3 version, as from this version onwards the XML of the relax save and results files will be differently formatted.
        * Big bug fix for the installation path for the relax Mac OS X application.  The path to the application Resources folder, where all the relax data files are located, is now set to the install path.  The relax.py module was also overwriting the value set in the status singleton and now this no longer occurs.
        * Fix for the py2app setup.py script for Mac OS X application creation - the list of data files to include with the app is now properly formatted.
        * The relax GUI is now robust and able to withstand a call to the reset user function - this could have occurred if the user ran a script with a reset() call, or if reset() was typed at the GUI version of the relax prompt.
        * Added isatty() methods to all of the dummy file objects within relax - this fixes a number of errors caused by the recent introduction of coloured text.
        * Fix for the initialisation of the Exec_info class for the prompt/script output.
        * Fix for the residue.create user function GUI front end - the unnamed molecules are now properly handled, and the gui_to_*() methods are now used for data conversion.
        * Fix for the gui_to_int() function for when text instead of an integer is given by the user.
        * Bug fix for the spin.create user function GUI interface for when molecules or residues are not named - unnamed molecules are now properly handled in the GUI page, and the residue name of None is properly converted into a NoneType prior to executing the back end.
        * Big bug fix for the deletion of analyses tabs from the GUI - this affects wxGTK users on Macs and Linux.  Now the spectrum and relaxation data list GUI elements have observer_register() methods, allowing the analysis delete_all() method to unregister all analysis specific methods from the observer objects.
        * Multiple unregistrations of observer methods are now possible without a RelaxError - this allows multiple code paths to unregister methods to allow for pre-removal of methods to avoid queued wx events in wxGTK from occurring on dead or missing objects.
        * Bug fix for the GUI when deleting analysis tabs - the deletion of analysis tabs was previously failing in certain cases.
        * Fix for a bug triggered by wxPython 2.9 when deleting the last analysis tab - the self.notebook object is now deleted when the set_init_state() method is called, allowing it to be properly accessed and recreated.
        * Converted the pipe switching with GUI tab switching to synchronous to avoid rare races (triggered by wxPython 2.9).
        * The analysis deletion buttons now do nothing if the notebook is not created yet - this avoids problems on the new wxPython 2.9 versions.
        * Fix for the radiobutton group in the Spectral_error_type_page of the peak intensity wizard.
        * Fix for the spin loading wizard of the spin window - the RadioButtons of the first page for selecting the spin loading method are now fixed.
        * Fix for the about relax window size for wxPython 2.9.
        * Fix for the relax controller find dialog on Mac OS X with wxPython 2.9.
        * wxPython 2.9 fix for the spin viewer window (at least for Mac OS X).
        * The maximize calls for the spin viewer window are now turned off for Mac OS X systems (this is a fix for the fink versions of relax).
        * Bug fix for Mac OS X - the main window is no longer started maximised (a fix for the fink version of relax).
        * Fix for the spin viewer window for wxPython 2.9 - this is for when you right click in the tree view panel on nothing.
        * Fix for the text on the 'finish' button of the GUI wizard - this was accidentally changed to 'apply'.
        * Bug fix for the spectrum.replicated user function for when it is called twice with the same IDs.
        * Bug fix for the relax GUI spin viewer window.  When right clicking on nothing in the tree view, an error would occur.  Now, instead, a special menu pops up with a single entry for loading spins.
        * Fix for the building of the relax C modules as universal binaries on Mac OS X - the linking was not functioning correctly, and the resultant module was build only for i386.
        * The relax Mac OS X dock icon is now turned off when using the wxGTK build of wxPython from fink - this prevents a little grey frameless window appearing with the largest of the relax Ulysses butterfly icons in the centre.
        * Bug fix for Mac OS X - attempt at killing the Carbon.Evt.TickCount problem by removing argv emulation.
        * Fix for the scons binary_dist target on Mac OS X systems with multiple Python versions - now the py2app program is called with the same python version as used by scons.
        * Fix for the Processor.data_upload() method.  The self.run_command_queue() method is no longer being used.  Instead the add_to_queue() method is being used to queue up the slave commands, and the run_queue() method is being called at the end to flush the queue.
        * Fixes and clean up of the slave to master transfer mechanism for result commands.
        * Fix for the relax info print out on Python 2.5 or below.



Version 1.3.14
(19 March 2012, from /1.3)
http://svn.gna.org/svn/relax/tags/1.3.14

    Features:
        * An expanded system information printout (from 'relax -i').
        * Improvements to the multi-processor implementation, including creation of a public API and a reference implementation.
        * Overhaul of the multi-processor stream capture design - the slave IO streams are now properly redirected to the master processor and the master no longer overrides stream capture by the relax user interfaces.
        * Numpy data structures are now supported in relax save files.
        * Implemented the rdc.delete and pcs.delete user functions.
        * Speed ups of a number of user functions involved in looping over atomic or spin specific data - this can be significant if a lot of structural operations are performed, or a large number of structures are required.
        * Redesigned how spin parameters are handled in the specific analyses (which includes parameter name changes).


    Changes:
        * The MS Windows text wrapping width has been changed from 80 to 79 - this now fits the cmd prompt.
        * The program intro print out and prompt UI help system is using the new Status.text_width variable to wrap text.
        * The model-free constraint matrix A is now of numpy.int8 type - this is to decrease virtual memory usage and increase the scaling efficiency on clusters.
        * Changed all relax website links to http://www.nmr-relax.com for consistency.
        * The setup.py script can now be imported for the epydoc API documentation system.
        * The extern and minfx.scipy_subset relax packages are excluded form the API documentation.
        * Added the ability to skip scripts in the package __all__ list unit test checks.
        * Added some code to detect the bit version of MS Windows in the information print out (to better distinguish 32 vs. 64-bit versions).
        * Added some documentation about master processors on Linux 2.6 eating 100% of one CPU core (in the mpi4py multi-processor fabric).
        * Added a reference implementation to the multi-processor package - this is to demonstrate to users of the package how an implementation is created via the public API.
        * Elimination of all relax dependencies from the multi-processor package.
        * Added support for the memory size on MS Windows to the relax info print out.
        * Updated the value.set user function unknown parameter error message to list the known ones.
        * For Unix and GNU/Linux systems, the relax info printout now shows the ram and swap size.
        * Expansion and improvement of the information printed out by 'relax --info'.
        * Expansion of the multi-processor API documentation.
        * Expansion of the multi-processor package documentation with a step by step usage guide - this should increase the usability of the package by clarifying how one should use it.
        * Expansion and improvements to the multi-processor package and module docstrings.
        * The finish button in the new analysis wizard has been renamed to "Start".
        * Created a special Verbosity singleton for controlling the multi-processor package print outs.
        * Future proofed the relax codebase by replacing all ''' with """ in the docstrings.
        * Removed the unnecessary try statement in the model-free Slave_command.run() method as exception handling is correctly performed on the slave and master.
        * Shifted the Memo object into its own module (multi package).
        * Simplification and abstraction of the Slave_command.run() method to shift all exception handling into the package.  Therefore program code no longer needs to handle the multi-processor specific errors.
        * Created a new module 'multi.misc' for holding miscellaneous functions used throughout the multi package.
        * Created a public API for the multi-processor package, available via multi.__init__.
        * The load_multiprocessor() function is no longer a static method of the Processor base class.  This function loads the correct Processor class, so doesn't need to be a method of the base class and operates cleanly and more clearly as a stand alone function.
        * Clean up of the processor IO module (multi package).
        * Eliminated all usage of sys.__stdout__ and sys.__stderr__ in the multi-processor package - this returns full control of IO streams to the parent program.
        * The float arg checks now checks against all the numpy float types (float16, float32, float64, float128).
        * Added value.write user function calls to the J(w) mapping system test script.
        * Added some value.write user functions to the J(w) mapping sample script.
        * Modified the J(w) mapping test data to include relaxation values of None to trigger bug #19329.
        * Speed up for the generic_fns.relax_re.search() function.
        * More speed ups for the Selection.__contains_mol_res_spin_containers() method.
        * Reordered the checks in Selection.__contains_mol_res_spin_containers() - this cuts the number of function calls down by avoiding relax_re.search() calls if residue or spin numbers match.
        * Simplified the generic_fns.relax_re.search() function - this is to minimise the number of isinstance() calls when dealing with the relax mol-res-spin sequence data.
        * Updates for Python 3.0 using 2to3.
        * Removal of a number of debugging print out statements.
        * Significant speed ups of the return_spin() and return_residue() functions.
        * Added a print out for the diffusion_tensor.init user function to inform the user of an angle unit change - this is in response to bug #19323 to make it clearer that a parameter conversion has occurred.
        * Created a special specific API object called SPIN_PARAMS - this will be used to handle all operations to do with model parameters.  The object Param_list has methods for parameter initialisation and handling (where all info is specified such as Grace string, units, default value, etc) and for determining if a parameter exists.
        * Mass conversion to the new GLOBAL_PARAMS and SPIN_PARAMS specific API data structures.  The parameters are now all lowercase, for example ['S2', 'te', 'Rex'] is now ['s2', 'te', 'rex'].  The follow parameters are now converted throughout relax: 'bond_length' to 'r', 'CSA' to 'csa', 'heteronucleus' to 'heteronuc_type', 'proton' to 'proton_type'.
        * Created a new algorithm for finding the pivot of motion between different structural models - this is available through the structure.find_pivot user function.
        * Added the validate_models() method to the structural API - this is used to check that the models are 100% consistent.
        * Added the centroid argument to the structure.superimpose user function - this allows for the superimposition of structures assuming a pivoted motion.


    Bugfixes:
        * Fix for the title of the analysis selection wizard GUI element.
        * Fix for the MemoryError during the "final" run of d'Auvergne Protocol affecting 32-bit systems (bug #19528).
        * Epydoc docstring fixes for the API documentation.
        * Bug fix for old numpy versions missing the float16 object.
        * The relax prompt mode now prints the intro message to sys.stdout - this fixes this mode with the logging option or in the mpi4py multiprocessor mode.
        * Fix for the storage of numpy data structures in the relax save files - if special structures are created by the user, these were not correctly stored.  The precision was often too low (printed at the numpy default of a precision of 8), and if one dimension had more than 1000 elements, ellipses would be stored instead (the ellipses would cause the save file to be unreadable by relax).
        * Created the SplitIO.flush() method so that a flush() call now works with the -t and -l command line args - this simply calls the flush() methods of both streams.
        * The relax data store __repr__() method now prints out all objects within the base object.
        * Fix for a rare bug in the model-free analysis for when relaxation data of None is encountered.
        * Fixes for the Dasha system test for the bug #19332 fix.
        * Fixes for the Dasha use functions for file creation and data extraction - this should now handle relaxation data values of None, and also set the parameter values of deselected spins using the Dasha output files.
        * Big bugfix for the value.read user function - the wrong spin ID string was being used to set the parameter value so that all spins have the same value set for the parameter(bug #19332).
        * Bug fix for the consistency testing analysis for when relaxation data of None is encountered.
        * The spin is now deselected if there is really less than three data points, excluding data points of None (bug #19329).
        * Bug fix for the arg_check.is_none() function - the RelaxNoneError was not imported!
        * Fix for the numbering of the TER record and subsequence HETATM records in the PDB file creation.  The structure.write_pdb user function now creates the correct TER record after the ATOM records, and the HETATM records are renumbered if needed.
        * Bug fix for the compilation of the user manual.  The molecule user function class used the temporary variable i, which was causing the fetch_docstrings script to fail.



Version 1.3.13
(10 November 2011, from /1.3)
http://svn.gna.org/svn/relax/tags/1.3.13

    Features:
        * The positive and negative cones from the frame order theory are now different PDB models.
        * Monte Carlo simulations are now implemented for the frame order analysis.
        * Created the structure.connect_atom user function to expose the back-end functionality.
        * Created the structure.add_atom user function to expose the back-end functionality.
        * Created the structure.translate user function to translate structural components.
        * Created the structure.superimpose user function which uses the Kabsch algorithm to implement the direct fit-to-first algorithm and the iterative fit-to-mean algorithm.
        * Created the structure.displacement user function to calculate the rotational and translational displacement between two models via the Kabsch algorithm.
        * Extended the N-state model analysis to allow a separate paramagnetic centre per state.
        * The structure.read_pdb user function can now handle bzip2 or gzip compressed PDB files.
        * The structure.write_pdb user function can now create compressed (bzip2 or gzip) PDB files.
        * Created the structure.rotate user function to allow the application of arbitrary rotations to the structures loaded into relax about a given origin.
        * Added the bc flag to the RDC and PCS display and write user functions to allow the back-calculated data to be displayed or written rather than the measured values.
        * Increased the efficiency of the relax data store spin system creation, this becomes noticeable when large numbers of structures are read into relax.
        * The N-state model can now be optimised with a subset of the alignment tensors fixed.
        * The alignment_tensor.fix user function is now tensor specific, allowing a subset of tensors to be optimised while the others are kept fixed.
        * Added the ability to specify J+D verses J+2D measured RDCs.
        * Addition of many new oxygen icons for the GUI.
        * Implemented the sys_info user function in all UI modes (prompt/script/GUI).
        * Implemented the spectrum.delete user function in all UI modes (prompt/script/GUI).
        * Addition of the pymol.macro_apply, pymol.macro_create, and pymol.macro_run user functions for the visualisation of model-free parameters mapped to a structure.  This matches the equivalent Molmol user functions and styles.
        * A complete redesign of the GUI where any number of analyses can be created and closed as needed.
        * The GUI is now fully functional on Mac OS X and MS Windows.
        * The elimination of many race conditions causing the GUI to crash.
        * Implementation within the GUI of many of the relax user functions available in the prompt and scripting UI modes.
        * Creation of the test suite GUI test category to complement the system and unit tests.
        * Added a toolbar to the main relax window with some of the most important menu entries as icons.
        * Most parts of the GUI are now deactivated when execution is in progress (via the execution lock) to prevent fatal race conditions.
        * Redesigned the dauvergne_protocol, NOE and Rx auto-analyses to use a pre-prepared data pipe for data input.  This allows greater support for the GUI and for analyses of RNA, DNA, and small molecules.


    Changes:
        * Changed the name of the model_num argument to model in the centre_of_mass() function.
        * The generic_fns.structure.mass.centre_of_mass() function now accepts the model number argument, allowing specific models to be isolated.
        * The generic_fns.structure.mass.centre_of_mass() function now accepts the atom ID argument, allowing the centre of mass of subsets of the structure to be calculated.
        * Addition of a number of frame order test data and system tests for the simpler models (Frame_order.test_cam_rigid, Frame_order.test_cam_free_rotor, Frame_order.test_cam_free_rotor2, Frame_order.test_cam_rotor, Frame_order.test_cam_rotor2, Frame_order.test_cam_iso_cone_free_rotor, Frame_order.test_cam_iso_cone_free_rotor2).
        * More use of the structural API in the create_diff_tensor_pdb() function.
        * Created the add_model() structural API method.
        * Eliminated one of the eigenframe parameters from the rotor frame order model.  In the rotor frame order model, the x and y axes of the eigenframe of the motion are not defined.  Therefore the 3 eigenframe Euler angles have been replaced by 2 spherical angles defining the rotation axis removing a lot of optimisation issues with this model.
        * The frame order torsion angle cone_sigma_max is now forced to be positive.  Optimisation sometimes comes up with the negative of the angle but, as both the negative and positive angles are the same result, the angle is always unpacked after optimisation as the absolute value.
        * Added a check to prevent the frame order grid search from being too big causing out of memory errors.
        * The internal structural object no longer requires the 'ATOM' PDB record for creating PDB files.  This affects the structure.write_pdb user function.
        * Added the translate method to the structural API.
        * Created the Structure.test_superimpose_fit_to_mean system test to test the 'fit to mean' algorithm of the structure.superimpose user function.
        * Shifted the structural API calc_displacement() method into the main module.
        * Created the arg_check.is_int_list() function for checking for lists of integers.
        * Created the Structure.test_superimpose_fit_to_first system test to test the 'fit to first' algorithm of the structure.superimpose user function.
        * Added the centroid argument to the structure.displacement user function for pivoted motions.  By specifying the centroid position for all structures, a pivoted motion is assumed.  All displacements will be zero, and the angles will be that of the pivoting motion.
        * Created the Structure.test_displacement system test for checking the structure.displacement user function.
        * Added checks for the n_state_model.cone_pdb user function in the N_state_model.test_5_state_xz system test.
        * Added a few new argument checks for arrays and matrices of floats including arg_check.is_float_array() and arg_check.is_float_matrix().
        * Added a few new RelaxError classes (RelaxNoneListFloatError, RelaxMatrixFloatError, RelaxNoneMatrixFloatError) and the BaseArgError class was also modified to handle the length argument (now the size arg) being a tuple for matrix sizes.
        * The N-state model Monte Carlo simulations can now handle fixed alignment tensors.
        * Created the alignment tensor module return_tensor() function for returning tensors.  This takes fixed tensors into account, skipping them if the skip_fixed flag is set.
        * Created the alignment tensor module num_tensors() method for counting tensors.  This excludes fixed tensors by default.
        * The RDC and PCS display and write user functions now output molecule name, residue name, residue number, spin name and spin number columns instead of the spin ID column.  This is better to read back into relax as info such as the spin number can be ignored, allowing different PDB files to be used.
        * Created a system test for loading RDCs from a file with spin ID strings at the start.
        * Created the N_state_model.test_metal_pos_opt N-state model system test.
        * The RDC and PCS Q factors for each alignment is now stored as a dictionary in the relax data store.
        * Updated the N-state model analysis code to handle the per-alignment tensor fixed flag.
        * Updated the relax data store alignment tensor objects to allow for the per-tensor fixed flag.
        * Created the generic_fns.align_tensor.all_fixed() function for determining if all tensors are fixed.
        * Created the Grace.test_cam_kkalpha_plot1 system test for checking the grace plotting of mixed data.
        * Created the N_state_model.test_monte_carlo_sims system test for checking MC sims with alignment data.
        * Updates for Python 3.0 using the Python 2to3 script.
        * Created the N_state_model.test_rdc_tensor system test for catching a strange RDC back calculation bug.
        * Created the Mf.test_bug_18790 system test for catching bug #18790.
        * Created the Relax_fit.test_bug_18789 system test for catching bug #18789.  The Grace file is written out, re-opened, and then the numbers checked.
        * The GUI test result classes are now being used by the GUI test suite code path.
        * Implemented some new classes to allow better control of the test suite from the GUI.  The GuiTestResult and GuiTestRunner classes have been added to the relax_test_runner module, and these are used rather than RelaxTestResult and RelaxTestRunner if the from_gui flag is sent to the main Test_suite_runner class.
        * The test result handling is now performed 100% in test_suite_runner.  Previously each class of test (system, unit, and GUI) were managing a separate instance of RelaxTestRunner.  Now it is all controlled from one spot.  This will allow better management of the tests from the GUI.
        * The results of the unit tests are now going to the proper sys.stdout stream.  The text was previously sent to the initial stream that sys.stderr is set to.  This is overwritten by relax though to be able to send it to the relax controller.  This allows the results to be captured.
        * Added the 'Tools->Test suite' menu entry.
        * The checks in the model-free analyses for correct relaxation data errors now prints out the spin ID string.
        * The test suite runner 'tests' argument now defaults to [] which is the proper null value.
        * Renamed the 'Settings' menu to 'Tools'.
        * The results viewer window now only executes one user function for the diffusion tensor if PyMOL is missing, preventing 3 errors (with windows) from appearing.
        * Modified the GUI interpreter apply() method to catch RelaxErrors.  Now gui_raise() is used to raise the error and show a dialog, and the method returns the execution status.
        * The diffusion tensor PDB in the results viewer is now launched by synchronous pymol user function calls.
        * The C modules are now compiled as universal binaries on Mac OS X.  This includes the targets i386, x86_64 and ppc64 by default.
        * The relax information print out now includes the version and path info for the mpi4py and wx modules.
        * The spectrum ID is no longer stored if spectrum.read_intensities fails to load any data.  A call to the delete() function has been added to remove all data loading prior to the error.
        * Redesigned the gui_raise() function so that it is more user friendly.  The relax controller window with error message is shown first, followed by the modal RelaxError message dialog on top of all other windows.
        * The spectrum.read_intensities user function now throws a RelaxError if no data was loaded.  This is to tell the user that something went wrong, and makes more sense in the GUI mode.
        * With debugging turned on, the relax test suite no longer captures the IO streams.  This will allow for better debugging of racing in the GUI tests on MS Windows.
        * Removed the brackets from the user function names in the RelaxError system as these make no sense in the GUI version of the user functions.
        * Clicking on 'Execute relax' now raises the relax controller to the front, if already shown.
        * The GUI prompt window is now also deactivated with the execution lock.  This will prevent race conditions as previously the user was able to execute any user function or manipulate any of the data in the relax data store while execution was in progress
        * More of the main menu entries have been disabled with the execution lock to prevent racing.
        * The spin loader toolbar button in the spin viewer window is now properly disabled with the execution lock.
        * The spin loader button in the spin viewer window is now deactivated with the execution lock.
        * The wizard page base method on_apply() now does nothing.  This should help eliminate Mac OS X bugs.
        * The scipy python package is now listed with the relax info (-i flag).
        * The peak list and relaxation data GUI element pop up menus are now disabled with the execution lock.  This will prevent weird bugs.
        * The spin viewer window is now properly maximised on MS Windows.
        * Improvements to the showing of the relax controller on errors and warnings.  The Show() call is no longer made if already shown, and if not shown, the LogCtrl is scrolled to the position of the error message.
        * The relax controller is now shown on all errors and warning (or raised if below other windows).
        * The View menu entries now raise the window to the front if already open, this is useful when too many windows are open.
        * The spin.name page is now added to the front of the Rx peak list wizard.
        * The spin.name GUI page is now added to the front of the NOE peak list wizard if spins are not named.
        * Expanded the spin.name user function docstring.
        * Shifted the spin ID field to the end of the spin.name user function GUI page, this is to make it easier for users as it is often assumed that the first field is the important one.
        * The proceed_on_error flag is now taken into account by the wizard's finish button.
        * The Rx peak list wizard now no longer skips to the next page when an error occurs.
        * All GUI user functions now use the base page execute() method instead of the interpreter directly.
        * Created the user function base page execute() method for running the user functions.  This will launch the interpreter in either asynchronous or synchronous mode dependent on the sync flag.
        * The sync flag is now set for all of the pages of the NOE peak list wizard.
        * The UF_page base class now accepts the 'sync' argument, this will be used to allow for asynchronous or synchronous operation.
        * The NOE peak list wizard should now stop proceeding on all errors.
        * Modified all of the gui_to_*() functions to catch a real None input value.
        * Created the gui.misc.gui_to_str_or_list() conversion function.
        * Created the gui.misc.gui_to_int_or_list() conversion function.
        * The relax controller menu now has icons.
        * The relaxation data list GUI element now has a pop up menu with a 'Delete' entry.
        * The relax data list delete button now opens with the first selected item in the list.
        * The relax_data.delete GUI user function can now have a starting ID string value.
        * The peak list GUI element ListCtrl now has a pop up menu with a 'Delete' entry.
        * The peak list GUI element now has a delete button which launches the spectrum.delete user function.
        * The spectrum.delete user function can now be started with an initial ID string.
        * Created the RelaxSpectraError and RelaxNoSpectraError error classes for spectral data.
        * Improvements to the wizard _display_page() method.
        * The user function class is no longer stored in self.gui.
        * Elimination of the self.gui class object.
        * Converted the results viewer window to handle the new user function GUI page design.
        * Better support for running a script and the GUI from the command line, the script is now run at the very end, after all of the GUI is set up, and is run with a wx.CallAfter call.
        * The spin loading wizard is now accessible from the tree's root menu in the spin viewer window.
        * Added a toolbar button to the spin viewer window to launch a wizard for loading spins.  A simple wizard has been created for the spin viewer window for loading spins which directs the user to either the sequence.read user function or the structure.read_pdb and structure.load_spins user functions.  The wizard page Load_method_page has been added at the start to allow the user to choose the method, and the last page Finish_page has been added so that the wizard can have a finish button and terminal page.
        * Converted all of the user function GUI pages to use the new create_wizard() base method.  This significantly simplifies the code.  The functions also no longer expect a wx event.
        * The deselect user function GUI pages no longer expect the user function page to be returned.
        * Added the return_page argument to create_wizard() so that the user function page can be selectively returned.
        * Complete redesign of the user function menu system, this is now more flexible and should be more compatible with window ordering under MS Windows.
        * Simplified the deselect user functions using the new GUI user function design.
        * The create_wizard() method now returns the user function page, this will be needed as sometimes the fields have to be changed.
        * Removed the now useless UF_base.__init__() method.
        * The User_functions class no longer takes any arguments.
        * The interpreter singleton is now being used by the user function GUI pages (part of the elimination of self.gui).
        * The relax GUI no longer starts maximised if debugging is on.
        * The script GUI user function is now operational again, the interpreter object is now imported and the synchronous apply() rather asynchonous queue() method is now used.  This allows the execution lock to be released by the script at the end.
        * The script user function GUI element now uses wx.GetApp() to access to the relax controller window.
        * The GUI Main instance is now stored in the wx.App as self.gui, this will allow access to the GUI class via wx.GetApp() calls, avoiding the need to pass the instance around (part of the elimination of self.gui).
        * The screen is no longer cleared prior to relax execution on MS Windows preventing the Windows PowerShell history from being wiped out.
        * Improved the RelaxError messages in validate_sequence(), the invalid data is now printed so that the user can see why it is invalid.
        * Improved the print outs of the scons 'binary_dist' target for Mac OS X.
        * Modified the 'clean' scons target to remove the py2app build and dist directories (for Mac OS X).
        * Created the 'scons binary_dist' target for Mac OS X.  Typing 'scons binary_dist' on a Mac will now create a DMG image of a universal Mac OS X application.
        * Added the Mac OS X DMG distribution file names to the scons script.
        * Modified the setup.py file so that the Mac OS X .app creation code is in the mac_setup() function.
        * Updated the hdiutil command options for the Mac OS X DMG file creation.
        * Added instructions to the setup.py file for creating a Mac OS X DMG distribution file.
        * Removed the GUI wait_for_interpreter() method as this is replaced by the interpreter flush() method.
        * Text files in the results viewer window are now opened with a text editor on Mac OS X and MS Windows.  On a Mac, the text file of NOE values was being opened up in 'Saturn', as the file ending '*.out' is associated with that software.
        * The gui_error() window caption is now simply 'RelaxError' rather than the specific relax error name, this now matches the prompt/script print outs which only have RelaxError (unless debugging is turned on).
        * The GUI tests in the test suite no longer have IO redirected to a window in Mac OS X and MS Windows.
        * Deleted the old gui.filedialog.opendir function and replaced it with a specialised RelaxDirDialog class.  This class is more advanced in that it changes the Python working directory so that the user does not have to always navigate back to the same place if relax is launched from a different directory.
        * The RelaxFileDialog object now changes the relax working directory as the user changes directories.
        * The Rx spectra list wizard now uses the on_init() wizard page method for the page updates.  This prevents the values in the pages being reset when the apply button is clicked.
        * Created the GUI wizard page method on_init(), this is executed each time a wizard page is newly displayed.
        * Removed the check for Monte Carlo simulations from the monte_carlo.setup user function allowing MC simulations to be run more than once.
        * The results viewer window no longer shows 1 warning dialog per results file.  At the end of the analysis, one warning dialog per results file was being shown as the execution lock was on.  Now a special method for the 'result_file' observer object has been added which skips this dialog.
        * The Monte Carlo simulation state is now turned off after the MC analysis is complete.  This allows the user to make slight modifications and rerun the analysis and optimisation.  The monte_carlo.error_analysis user function switches the state at the very end, just as monte_carlo.setup switches the state to on.
        * The relax execution lock now has debugging print outs.
        * The status container instance is now private in the Relax_lock objects.
        * The fake_lock variable in the status module classes is now private.
        * The spin_id_to_data_list error messages are now more informative.
        * The RelaxInvalidSeqError now prints out a more detailed message for the validate_sequence() function.
        * The flush flag is set for the first page of the Rx peak height loading wizard.
        * Added the ability to flush the GUI interpreter thread in the wizard prior to changing to the next page, this will help in solving races when a series of user functions are strung one after the other.
        * The notification of observers in status.observers.gui_uf has been modified.  The GUI user function pages no longer perform this as the calls to the interpreter are via the interpreter thread, hence the completion of the page does not signal the completion of the user function.  Instead the interpreter thread (and the synchronous apply() call as well) perform the notification once complete.
        * The GUI auto-analyses now initialise with a synchronous call to pipe.create(), this uses the GUI interpreter object apply() method to prevent race conditions.  This is important as the pipe creation needs to be completed prior to the setting up of the GUI elements.
        * Created the GUI interpreter object apply() for synchronous calls to the user functions.
        * Redesigned the GUI interpreter object so that the thread is a separate object, this is to allow both synchronous and asynchronous calls to the interpreter.
        * Added the _get_uf() method to the GUI interpreter object for abstracting the code.
        * All the model-free macro methods are no longer private, the class will not be used as a base class for the model-free specific class.
        * Abstracted the model-free 'classic' Molmol and PyMOL creation in to a base class.  As most of the code between the specific_fns.model_free.molmol and specific_fns.model_free.pymol modules is identical, significantly simplifying the code base.
        * The results viewer window can now open Molmol macro files.
        * The results viewer will now open PyMOL files in PyMOL via pymol.macro_run.
        * Modified the Molmol macro related user function front end to match those of PyMOL, there are: molmol.macro_exec is now molmol.macro_apply; molmol.write is now molmol.macro_write; molmol.macro.run has been added to execute macros from text files.
        * The GUI interpreter thread is now flushed prior to execution of the auto-analyses.
        * Created the GUI interpreter thread flush() method for blocking until the queue is empty.
        * Added a join() wrapper method for the GUI interpreter thread internal queue.
        * Added the empty() method to the GUI interpreter thread to determine if the internal queue is empty.
        * Some cleaning up of the mpi4py processor module.
        * Removed a pile of unused code from the mpi4py processor module.
        * Removed the _sys_exit module variable from the mpi4py processor as it is unnecessary.
        * Eliminated the restore_stdio() method from the multi package, the redirection of IO streams is totally incompatible with an IO redirection performed by the underlying Python program.
        * Removed the IO redirection from the uni-processor return_object() method.  The IO redirection in the 'multi' package overwrites all IO redirection any Python program is attempting to perform.
        * The uni-processor call to capture_stdio() has been removed, no IO redirection will be performed in uni-processor mode.
        * Deleted the STDOUT and STDERR capture in MF_minimise_command multi-processor class as it was breaking both the GUI and the test suite.
        * Removed the multi_processor module as this is now called multi_processor_base.  This was deleted a long time ago but somehow survived in one of the branches and was merged back in.
        * Renamed the PrependOut class to IO_filter in multi/processor_io.py.
        * Renamed the prependStringIO module to processor_io in preparation for a redesign.
        * Clean up of the multi-processor IO module.  The Multiplex_stdout class has been deleted as this is the wrong way of handling the IO streams and is unused anyway.  The PrependStringIO class has had the getvalue() and truncate() methods removed as these need not be implemented as it is provided by StringIO.
        * Created Redirect_text.flush() for the relax controller for compatibility with the multi-processor code.
        * All calls to user functions in self.gui.interpreter now pass through the queue() method.
        * The 'relax_gui_mode' module is blacklisted from the epydoc documentation generation.  Without this, the relax GUI launches when executing 'scons api_manual_html'.
        * The dauvergne_protocol auto-analysis now creates the PyMOL macros for the model-free data.
        * The molmol.write and pymol.write now add the macro files to the result files list.
        * The dauvergne_protocol auto-analysis now generates MOLMOL macros and text files with the parameters.
        * The interpreter thread no longer dies when an error occurs.  This has been redesigned so that the error catching occurs within the infinite loop.  Without this the user functions are completely useless after an error and do nothing.
        * RelaxErrors are handled as in the auto-analyses and prompt/scripting mode in the GUI user functions.  The traceback is now suppressed and a dialog with the error is show.
        * The print outs for catching exceptions in threads is now going to STDERR rather than STDOUT.
        * sys.__stdout__ and sys.__stderr__ are no longer being written to.
        * Saving the relax state from the GUI now shows the busy cursor for user feedback.  After MC sims saving the state can take a few seconds with the GUI frozen, so this feedback is necessary.
        * Errors are now handled properly in the interpreter thread for GUI user functions.
        * The GUI analysis execution threads are now daemonic to allow relax to exit.
        * Redesigned how user functions are executed in the GUI so they are queued and launched in a thread.  This allows the GUI to be responsive while the user functions execute.  This is only at the level of the GUI and not the relax interpreter.  The execution lock is also acquired to lock up the GUI while the user function executes.  A special daemon thread called self.gui.interpreter has a queue object so that a series of user functions can be queued up if needed.  The program now also exists with wx.Exit() call to prevent unhandled exceptions occurring in this daemon thread.
        * The pipe.create user function page is now using PIPE_DESC to present a list of pipe types for the user.  This gives the descriptive name of the data pipe type rather than the keyword argument values.
        * Created the PIPE_DESC dictionary to provide descriptions of the data pipes.
        * The consistency testing and hybrid data pipes are now listed in the pipe.create user function docstring.
        * The GUI now returns to normal when opening an invalid or incompatible save file.
        * Molmol is now properly launched from relax to read commands from STDIN.
        * Synchronised the code for handling Molmol and PyMOL.  The Molmol code is now very similar to that of PyMOL, using subprocess.Popen rather than os.popen.  There is now a Molmol execution object that is used by the molmol user functions.
        * The GUI tests are now skipped when the wx module is not present (or is broken).  This allows relax to operate without having wx installed.
        * Modified the dauvergne_protocol auto-analysis to be able to loop over all the global models.  The diff_model argument can now be a list of global model names, allowing the protocol to loop over each diffusion model.
        * The results viewer window also updates via the result_file observer.
        * The result_file observer object has been created and is being used throughout relax.
        * PyMOL is now always launched as an external program as the pymol module loading method was causing huge problems for the GUI.
        * Diffusion tensor PDB files are now opened in PyMOL from the results viewer window.
        * The cdp.result_file structure has been modified to include a type, a label, and the file path.
        * The results viewer window presents the results files in a wx.TextCtrl.
        * The results viewer window is deactivated with the execution lock.
        * Modified the results viewer to operate like the spin viewer with respect to pipe changing.
        * The results viewing code (the viewer window) has now been separated from the analysis GUI code.
        * A diffusion tensor representation of the final results is created for dauvergne_protocol.
        * Grace plots of the final model-free results are now produced by the dauvergne_protocol auto-analysis.
        * Deleted the status_reset() method from the dauvergne_protocol auto-analysis as it served no purpose.
        * All the data pipes are cleared out in the final stage of the dauvergne_protocol.  This is to remove many of the temporary data pipes from view of the user in the GUI.
        * Removal of the unused gui.execution.calc_modelfree module.  This was a direct copy of the auto_analyses.dauvergne_protocol module, but is unmaintainable and of no use in the GUI anymore.
        * Modified the pipe editor window design to be closer to that of the spin viewer.  The observer methods are now unregistered on closing the window, which should speed up relax.
        * The data pipe and spin viewer window Show() methods are now only called if IsShown() is False.
        * Warning dialogs are shown if the pipe editor or spin viewer windows are opened during the execution lock.
        * Improvements to the user warning dialog about closing windows, the dialog is now only shown once at the start and it blocks the auto-analysis.
        * Added a message dialog to warn the user to close the spin viewer and pipe editor windows to speed up calculations.
        * Deleted the unused dir_message(), exec_relax() and relax_run_ok() message functions.
        * The pipe_lock and spin_lock (via Relax_lock) locks are now reentrant locks.  This allows nested locking via one thread, which is necessary as the functions of generic_fns.pipes and generic_fns.mol_res_spin often call functions of the same module in a nested way.
        * Created an object called Relax_lock to help debug locking issues in relax.  The status.spin_lock lock is now using Relax_lock.
        * All of the generic_fns.mol_res_spin fns which modify the data structure are now using the new lock.
        * Created the status.reset() method to resetting the status object.
        * Created a lock object for the molecule, residue and spin data structures.  This will be used to prevent races when spin data is being accessed and changed at the same time.  This affects the spin viewer window which is very sensitive to races.
        * The relax controller window is calling Layout() after updating to show all panels properly.  This is needed when showing the model-free or Rx panels.
        * Clean up of the showing and hiding of spin viewer window, all observers and registered now in the Show() method and unregistered in handler_close().
        * The R1 and R2 curve-fitting tabs are completely deactivated by the execution lock.
        * The NOE auto-analysis tab is completely deactivated with the execution lock.
        * The execute relax button is now turned off by the execution lock in the model-free auto-analysis tab.
        * The GUI analysis base class add_execute_relax() method now returns the button.
        * The add_spin_systems() base class method now returns the Text_ctrl instance it creates.
        * Converted the analysis base class add_text_sel_element() method to the object Text_ctrl.  This has the Enable(), SetValue(), and GetValue() methods implemented as a wx object.
        * Renamed the 'spin_ctrl' module to 'elements' to store all of the special GUI analysis elements.
        * More enabling/disabling of the model-free auto-analysis GUI element.
        * The spectrum list GUI element can also now be enabled/disabled via Enable().
        * The relaxation data list GUI element can now be enabled/disabled via Enable().
        * All the model-free auto-analysis activation and deactivation calls now pass through wx.CallAfter.
        * The model-free model fields are now activated/deactivated with the execution lock.
        * Created the Spin_control object for the analysis GUI elements from the base add_spin_element() method.  This class implements the Enable(), GetValue(), and SetValue() methods to mimic a wx control.
        * Tooltips are now given for the relax controller gauges and text fields.
        * The spin viewer tree pop up menus are now disabled when the execution lock is on.
        * All the spin viewer tree pop up menus now have IDs as class variables via wx.NewId().
        * The spin viewer menus and pipe switching elements are now disabled when the execution lock is on.
        * Many of the 'File' menu entries are now disabled when the execution lock is on.
        * The main menu IDs are now all class variables called self.MENU_* and are given by wx.NewId().
        * The pipe editor window is starting inactive if the execution lock is on.
        * Most of the data pipe functions are now using the data pipe locking object status.pipe_lock.  The functions which acquire the lock object and which modify the pipe state include: copy(), create(), delete(), switch().  The functions which acquire the lock object to prevent changes while they execute include: display(), pipe_loop().
        * Created a lock object for the relax data pipes.  This will be used to prevent races in the GUI when data pipe info is accessed, but when a thread is changing the data pipes at the same time.
        * The pipe editor window methods are now deactivated when the execution lock is on.
        * The original zoom level is available in the relax controller log control pop up menu.
        * Zooming can now be changed with Ctrl-+, Ctrl-- and Ctrl-0 in the relax controller, enabling zoom in, zoom out, and the original zoom to be accessed by the keyboard.
        * Created a replacement pop up menu for the relax controller log control.  This has functions for finding text, copying text, selecting all, and zooming in or out.
        * The relax controller log control can no longer have text inserted.  This was happening with the middle mouse button click on GNU/Linux.
        * A find dialog is now available for the relax controller log control to find text in the messages, this is available with Ctrl-F.
        * Deleted the now unused gui.execution.calc_rx module.
        * The GUI dauvergne_protocol test now uses the same optimisation settings as the system test.
        * The diff_tensor_grid_inc dauvergne_protocol argument is now available in the auto-analysis GUI tab.  This is not exposed to the user though.
        * The dauvergne_protocol GUI test is now checking the same data as the equivalent system test.
        * The solution for the dauvergne_protocol system test is reached after 1 iteration, so the test is shortened.
        * Better testing of the new diff_tensor_grid_inc argument to the dauvergne_protocol auto-analysis.
        * The dauvergne_protocol system test script can now run stand-alone.
        * Re-activated and redesigned the system test of the dauvergne_protocol.
        * The unit vector loading wizard is now stored in the base model-free auto-analysis class.  This is for access to the GUI element from the test-suite.
        * Fix for the unit vector check in the model-free auto-analysis GUI tab.
        * Added a button and created a wizard for loading unit vectors from PDB files.  This has been added to the model-free GUI auto-analysis tab.
        * Unit vectors are now only checked for in the model-free GUI auto-analysis when needed.
        * Full errors are raised in the protected_exec() function if in debugging mode.
        * Improvements to the structure.vector user function docstring.
        * Created the wizard page spin_control() method for adding a spin control.
        * The results file viewer is now executing the grace.view user function to display Grace files.
        * Fix for the protected_exec() method - the error is no longer raised so it can return False.
        * Implemented the NOE data_names() and return_data_desc() specific API methods.
        * The gui_raise() method now turns off the busy cursor if needed.
        * Added the 'Help->Licence' menu entry (this is a simple copy of 'User functions->gpl').
        * The results viewer window now uses cdp.result_files.  This decouples the files and their creation from the GUI.
        * The grid search increments default to 21 now in the Rx fitting auto-analysis GUI tab, the MC simulation tooltip now also recommends a min of 500 sims.
        * In debugging and test mode, the relax controller now writes back to the original IO streams instead of sys.__stdout__ and sys.__stderr__.
        * The relax controller log control styles are now set to the 'modern_small' fonts.
        * Expanded and renamed the 'modern' fonts.
        * RelaxWarnings are now coloured 'orange red' in the log control of the relax controller.
        * The Monte Carlo simulation number is now stored in the auto-analysis part of the status object.  This is only when an auto-analysis is running.
        * The relax prompt is now coloured blue in the relax controller log element.
        * The STDOUT and STDERR streams are segregated in the relax controller LogCtrl and STDERR messages coloured red.
        * The relax controller log window can now distinguish between STDOUT and STDERR messages.  STDOUT and STDERR are now being sent to separate instances of Redirect_text, and added to the log queue with a flag specifying which is which.
        * The relax controller and auto-analysis threads are now active in debugging mode.
        * The relax controller Redirect_text object is now placing all messages onto a log queue and the LogCtrl is reading from this queue.  The log_queue Queue object is now used to store messages so that not every write() event to STDOUT and STDERR results in the relax controller log window updating.  This allows the controller and the GUI to remain responsive as masses of messages are produced.
        * The new relax controller now appears to be thread safe.
        * The relax controller window now can move behind the other windows.
        * Key events are now controlled in the relax controller log element, this prevents text insertion and deletion.
        * Scrolling now follows the end, if at the end, in the relax controller log window.
        * Implemented limited scroll back on the LogCtrl relax controller log element.  This will prevent the computer from running out of memory.  The maximum number of lines is now stored in the status singleton.
        * Created a custom control for the relax controller log element.  This is derived from wx.stc.StyledTextCtrl and will allow much greater control.
        * Renamed the relax controller IO redirection append_text() method to add_text().
        * The gui_raise() function now only shows the dialog if the status.show_gui flag is set.
        * Shifted the exception_queue object into the base of the status object.
        * The spectrum.error_analysis can now be repetitively performed, this allows changes such as addition of new spectra to occur.
        * A timer is now being used to update the gauges of the relax controller, the gauges were previously not pulsing correctly.
        * The Question message dialog answer is now set to 'No' if the window close icon is clicked.
        * The Missing_data and Question message dialogs are now always on top, this prevents them from being hidden by other windows.
        * The gui_to_float() and gui_to_int() functions can now handle float or int inputs.
        * All of the gui_to_*() functions now check for empty unicode strings u'' as well.
        * Modified the gui_to_float() and gui_to_int() functions to handle expressions, this means that the float '1.23 * 1e-6' or '1.234 * 4 - 0.06' can input by the user.
        * The font is now set on the text of the Question message box.
        * Added checks for sequence and spectral data for the Rx curve-fitting and NOE auto-analysis GUI tabs.
        * All buttons in the GUI now have their fonts set.  This is for GUI consistency between GNU/Linux, Mac OS X and MS Windows.
        * The about relax dialog is now resized dependent on the extent of the text, fixing the dialog on MS Windows.
        * The wx.lib.wordwrap module is now used for wrapping the text in the about GUI dialogs.
        * Shifted the font initialisation to the very start of the GUI launching.
        * The results files lists are only updated if the files are not already there.
        * Complete redesign of the relax controller.  The new features include: A dynamically updated analysis specific status update; Analysis specific GUI elements, dynamically hidden or shown; A display of the current analysis and current data pipe; Correct updating of the gauges in all analyses; Separation of the text redirection and the progress updating; Text scroll back limited by default to 100000 lines; Text scroll back cleared as a user would expect with removal of lines from the start; Cleaner layout of all elements.
        * The dauvergne_protocol auto-analysis now stores the maximum number of iterations value.
        * Created the GUI analysis current_data() method for returning the data store container.
        * The auto-analysis status objects are now set up for all auto-analyses.
        * The auto-analyses status objects now have a completion flag 'fin' to indicate if the analysis is complete.
        * Added a new analysis method current_analysis_type() for determining the current analysis type.
        * The opening of the results viewer window after an analysis is now thread safe.
        * There is now an observer object for the execution lock.
        * The text redirection to the relax controller is set up in the controller removing repetition.  The redirection was happening in the controller first and then again in each analysis.
        * Modified how the auto_analysis status object behaves so setting values causes an observer to be notified.
        * The fonts are now set for all parts of the wizard pages for OS consistency.
        * The results display window is now shown at the end of the auto-analysis execution.
        * A busy cursor is now shown while waiting for the new analysis wizard.
        * The save_state flag has been added to the NOE auto-analysis so that the save state can be turned off.
        * Removed the no longer used GUI NOE calculation module (gui.execution.calc_noe).
        * The status bar is properly updated to show nothing if all data pipes have been deleted.
        * The setting up of a new analysis tab now uses freezing and thawing and the busy cursor.
        * The new_analysis method now checks that the C modules are compiled, and returns cleanly if not and an R1 or R2 analysis is selected.
        * The save state dialog now only shows *.bz2 files to save as.
        * The spin viewer now starts maximised on GNU/Linux and MS Windows, and at a smaller size on Mac OS X.
        * Polishing of the Question message dialog.  The buttons are now of fixed width and aligned to the right, and the relax-blue version of the dialog-warning oxygen icon is being used.
        * Created a relax blue version of the dialog-warning oxygen icon.
        * Layout improvements in a number of user function and other wizard pages, the description heights are now used (the variable had been renamed), and the free file format GUI element containing user function pages now use the space better and have been shortened.
        * The free file format resetting now properly updates the GUI element.
        * Polishing of the free file format GUI element.  The internal buttons are now placed to the right hand side rather than below to save large amounts of space.  A lot of unnecessary outside padding has also been removed, and the divider position is now properly calculated.
        * Updates to the GUI fonts, and the addition of normal_italic.
        * Improvements to the wildcards for the relax save state file dialogs.  There is now a separation between the compressed *.bz2 *.gz files and the 'All files' entry for selecting an uncompressed version.
        * The protected_exec() function now uses gui_raise() to handle errors.
        * The gui_raise() function now prints the error message to STDERR if the raise flag is not set.
        * Redesign of all the file dialogs in the GUI.  All file dialogs are now instances of gui.filedialog.RelaxFileDialog.  This fixes many inconsistencies throughout the GUI, includes presenting an wx.FD_OPEN style file dialog when a wx.FD_SAVE style should have been shown.
        * The PDB file selector of the structure.load_pdb GUI user function now only shows *.pdb files.
        * Removed combine_models from the structure.load_spins GUI user function page as that argument no longer exists.
        * Improvements to the free file format GUI elements (window and element).  This includes specifying fonts, button sizes, and a fix for the button sizer in the GUI element.
        * The GUI is now frozen while opening a relax state and then finally thawed, removing visual artifacts on Mac OS X.
        * Removed the 'Settings->Reset all settings' menu and added a reset button to the free file format settings.
        * The Question class can now have the parent specified to allow for sub-windows to have the dialog focus.
        * The missing data and question dialogs are now centred.
        * Converted the question() dialog launching function into a class derived from wx.Dialog.  This implements a custom yes/no dialog that is consistent between different operating systems.
        * Layout improvements for the wizard pages on Mac OS X.
        * Fix for the split/double help menu entry on Mac OS X, the SetMenuBar() call happens after all the menus are created.
        * Created a script for forcing relax's GUI mode (relax_gui_mode.py).
        * Added a script for building application packages of relax.  This currently supports the building of a stand alone Mac OS X app (i.e. no python needed).
        * The exit relax dialog now has a title.
        * The Mac OS X build and dist app directories have been added to the scons clean_all target.
        * Created a Mac OS X .icns version of the relax icon.
        * Created a task bar icon for Mac OS X.
        * The about windows now have titles (this makes the windows identifiable).
        * The relax icons are now used for all of relax's windows.
        * Better icon support in the GUI.  The ulysses.ico file is now being used as it is an bundle of images, and the icon bundle is now set for the main window.
        * Created transparent background images of the diffusion tensors for the model-free auto-analysis tab.
        * Added a series of 4 buttons for calling value.set in the model-free auto-analysis tab.  This is to make it obvious that the CSA, bond length, heteronucleus type, and proton type need to be set.
        * A number of improvements to the value.set GUI user function.  The on_display() method has been renamed to update_parameters() so the parameter list can be updated only when needed.  The set_param() method has been added to set a starting parameter and its default value.
        * The GUI user functions now show a busy cursor when loading so that the user isn't confused, wondering why relax is not responding.
        * The value.set GUI user function now sets the value to the default when parameters are selected.
        * Expressions can now be used in the value.set GUI user function for the number types.
        * Modified the gui_raise() function to have the raise_flag argument allowing the raising of the error to be skipped.
        * Created the analysis tab base class variable width_main_separator, this increases the space between the left hand side graphic and the right hand side elements.
        * relax is now started maximised in GUI mode.
        * The value.set user function GUI page now properly converts the value to the correct type.
        * The relax controller is now colouring the status module lock and observer print outs.
        * Improvements and fixes for the debugging print outs from the status module, and the text now goes to sys.stdout.
        * The observer objects are now printing out execution information when in debugging mode.
        * All acquire() and release() calls for the spin_lock and pipe_lock objects now are named, the name argument is now supplied to these methods.
        * The Relax_lock object now has much better debugging facilities, and responds to the debug flag.
        * Renamed the Relax_lock debug argument to fake_lock, again this is used to fake the locking mechanism, whereas debugging could be more fine grained.
        * The Relax_lock object now has a 'name' argument which will be used in debugging.
        * The pipe_lock locking object is now the special Relax_lock, this will allow for fine grained debugging.
        * All pages of the Rx peak list wizard now cannot proceed on an error, this will trigger the user function flushing.
        * A copy of the GUI interpreter singleton is now initialised in the wizard, this is used for the flushing of user functions prior to proceeding.
        * The GUI interpreter object has been converted into a singleton.

        * Changed the missing spin parameter messages to indicated that the value.set user function is needed.
        * Converted the missing data dialog into its own wx.Dialog derived class.  The dialog is now completely constructed by relax and will be constant across different operating systems.
        * Added data checks for the dauvergne_protocol GUI auto-analysis tab.  This allows for a dialog telling the user what is missing.
        * Redesigned the dauvergne_protocol mode selection in the GUI.  A special GUI element has been added to the analysis tab with a button that launches a new window for mode selection.  Therefore clicking on 'Execute relax' instantly starts the analysis.
        * Redesigned how the auto-analyses are handled by the status singleton.  The init_auto_analysis() has been created, and each analysis has its own status container within the status.auto_analysis dictionary.
        * Modified the dauvergne_protocol.py sample script to use the new design of accepting a filled data pipe.
        * Removed the 'exclude' file name from the model-free data assembly in the GUI.
        * Changing the model-free model selection in the dauvergne_protocol of the GUI now sets a red flag on the button.
        * The add_button_open() analysis base class method now returns the button.
        * Converted the relaxation data list GUI element to a wx.ListCtrl to match the spectra list element.
        * Converted the spectra list GUI element from a wx.Grid element to a wx.ListCtrl element.  This is visually more appealing, and is easier to control.
        * The question() dialog now only appears when the status.show_gui flag is set.
        * The SetValue() call for the model-free model list GUI element now updates the element with the new values.
        * A strong warning is now given to the user if they try to modify the model-free model list.
        * Implemented the model-free model selector window.
        * Created the gui.misc.list_to_gui() function for converting Python lists to GUI strings.
        * Removed the GUI README file as it is very much out of date.
        * Shifted all of the font definitions into the new fonts module.
        * Shifted the model-free model selection GUI element into the new Model_list class.
        * Expanded the docs for the relax_data.read user function to include the Varian and Bruker frequency parameters.
        * The spectrum and relaxation data lists now post EVT_SIZE events when modified.  This forces the parent scrolled panel to properly layout out its contents and refresh.
        * Removed visual artifacts in the wx.grid.Grid elements used in the spectrum and relax data lists.  All cells are now set to the background panel colour, and then individual cells are set back to white.  This removes the visual artifact of white outside of the wx grids.
        * Spacing improvements in all the auto-analysis GUI elements.
        * The virtual width of the analysis GUI elements now matches the real width.  The horizontal scrollbar has also been disabled.
        * Converted all of the GUI analysis objects into instances of wx.lib.scrolledpanel.ScrolledPanel.
        * The ds.relax_gui data structure is initialised if absent when associating a pipe with a new tab.
        * The popup menu is not shown if the status.show_gui flag is not set.
        * The auto-analysis initialisation can now associate with a pre-existing data pipe.
        * The data pipe editor now has a new 'Associate with a new auto-analysis' menu entry.
        * Added a hybridise button to the data pipe editor.
        * The data pipe editor is now registered with the gui_analysis observer.
        * The observer status.observers.gui_analysis is now notified of all changes to the analysis tabs.
        * Created an observer object (status.observers.gui_analysis) for changes to the GUI analysis tabs.
        * The execution of the callback functions in the observer objects is now ordered based on the registration order.
        * The data pipe editor can now be opened with Ctrl+D.
        * Changed the pipe_switch observer object to pipe_alteration and all pipe changes are now signalled.
        * Implemented the data pipe editor window, this will be used to manipulate data pipes including how they interact with the GUI.
        * Converted the menu build_menu_item() method into a function of gui.components.menu to allow it to be used more easily by other parts of the GUI.


    Bugfixes:
        * Fix for the pymol.cone_pdb user function for frame order models with no alpha average position angle.  This is specifically for the isotropic cone and free rotor model, although other models might also be affected by this fix.
        * Fixes for the add_molecule() structural API method.
        * Fix for the internal structural object add_molecule() method for when no models exist, now a model is created if none currently exist.
        * A lot of fixes for the internal structural object for handling multiple models.
        * The internal structural reader can now create PDB files if atom numbers are missing, fixing the structure.write_pdb user function in certain edge cases.
        * Bug fix for the pymol.cone_pdb user function for when there is no average domain position.  This is necessary for the old 2-domain N-state model analysis type.
        * Bug fixes for the n_state_model.cone_pdb user function, the code was old and not functional any more.
        * Fix for the frame_order.cone_pdb user function, the create_cone_pdb() function was referencing a non-existent variable.
        * Fix for the set up of Monte Carlo data for fixed alignment tensors in the N-state model.  The _minimise_setup_fixed_tensors() method has been fixed to return the actual tensor rather than simulation for the fixed tensors, as there is no simulation tensor in that case.
        * Bug fix for the relax_io.read_spin_data() function for spin IDs - spin IDs can now be handled if they are the first column in the data file.
        * Bug fix allowing relax to be run in profiling mode.  This has been broken since the merger of the multi-processor branch.
        * Fix for the paramag.centre user function when a numpy array is used.
        * Fixes for the N-state model optimisation setup if PCS or RDC data is not loaded.
        * Bug fix for the setup of the N-state model target function, triggered by missing data.
        * Fix for a divide by zero error in the PCS Q factor function.
        * The RDC and PCS Q factor functions are now more robust when data is missing.
        * Bug fix for the grace.write user function for when the spin ID is specified, the spin ID was previously unused.
        * Bug fix for the Monte Carlo simulation data generation for the N-state model.  The create_mc_data() method was always skipping RDC and PCS data due to an incorrect check for the presence of that data.
        * Bug fix for the logging and teeing command line options.
        * Bug fix for missing RDC back-calculated data (rdc_bc).  If a sequence is read from a PDB file, but the N-H bond vector cannot be extracted due to a missing proton, the alignment tensor fit to RDC data (specifically the Monte Carlo simulations) would fail.
        * Bug fix for a newly introduced dependency on the wxPython module.  This wx module is now optional, and only required for the GUI mode.  This allows relax to run without this module installed.
        * Bug fix for IO capture in the test suite with Python 2.6 or below.  The RelaxTestRunner._makeResult() replacement method has been reinstated.  Replacing the class variable resultclass does not work with earlier versions of the unittest site-package.
        * Fix for bug #18790 - the negative relaxation data errors.
        * Fix for bug #18789 - the zero errors in Grace files.  The problem was that the errors were being taken as the X-axis error values, which in the case of spin specific data is zero.  Now the Y-axis errors are taken rather than the unused X-axis errors.
        * The status.test_mode and status.show_gui flags are now initialised only once in the singleton to prevent them from being overwritten when a reset() call is made.
        * Mac OS X bug fix for changing pipes in the spin viewer window.  The pipe selector element event GetString() method was returning None as this is a read only ComboBox (in wxPython 2.9).
        * Fixes for Mac OS X with wxPython 2.9 for the spin viewer window activation/deactivation, this is now via wx.CallAfter() calls to prevent memory leaks.
        * Bug fix for Mac OS X when using wxPython 2.9.2.4 whereby wx.SafeYield() is causing 'Bus errors'.  The wx.SafeYield(None, True) calls have been replaced by wx.GetApp().Yield(True) calls, which should do the same thing but do not cause bus errors on this developmental version of wxPython.  This fix is important as the future Mac OS X relax app will use this version of wxPython for 64-bit and Cocoa support.
        * Bug fix for the reporting of non-matching lines in the spectrum.read_intensities user function.  The file data printed did not match the actual intensity data currently being processed, hence the wrong data was being printed as non-matching.
        * Fix for running the test suite in debugging mode.  The self.capt StringIO structure is always necessary for the final print out.
        * Fix for the results viewer window on MS Windows - it is no longer hidden after switching pipes.  For some reason MS Windows always brings the main GUI window to the front when pipe switches occur (probably the notebook switching).
        * Bug fixes for racing in the results viewer window on MS Windows, wx.CallAfter() calls are required for this to work.
        * MS Windows bug fix for pipe switching in the data pipe editor window, the pipe window would be hidden after the switch.
        * MS Windows bug fix for the pipe editor window, the wx.Yield() call has been removed from the update_grid() method as it causes a wx._core.PyAssertionError on Windows.
        * Bug fix for racing in the GUI on MS Windows when the relax prompt window is open.  This was caught in the test suite, and only affects MS Windows.  Now a wx.CallAfter() call is used to enable the GUI element.
        * Bug fix for the GUI interpreter thread flushing on MS Windows.  The Python Queue.empty() method is documented as being unreliable - and that is indeed the case on MS Windows (not on GNU/Linux or Mac OS X though).  It sometimes returns false, continually, when the queue is completely empty.
        * A lot of bug fixes for MS Windows with the handling of the busy cursor.  All calls to wx.EndBusyCursor() are preceded by a check via wx.IsBusy().  For some reason, in contrast to other operating systems, MS Windows will sometimes turn off the busy cursor by itself.  A subsequence call to wx.EndBusyCursor() results in an error.
        * Bug fix for the main window status bar on MS Windows, the text is now being set with wx.CallAfter calls.
        * Fixed a bug on MS Windows for the 'Close all analyses' menu entry and toolbar button.  The sequence of internal events is very different on Windows compared to Mac OS X and GNU/Linux, and not everything had been processed before everything was deleted resulting in updates to dead GUI elements.
        * Bug fix for the new analysis wizard cancelling on Mac OS X.
        * Bug fix for the closure of the new analysis wizard window.
        * Bug fix for MS Windows - the spin viewer window was being hidden by the main window when switching pipes.
        * Bug fix for racing in the spin viewer window when switching pipes.
        * Fixes for the peak list wizards for the NOE and Rx auto-analyses for Mac OS X.
        * Bug fix for many unit tests on MS Windows.  The os.tmpfile() call has been replaced by tempfile.mkstemp() in the data types passed into the unit tests of the prompt interface.  The os.tmpfile() call on Windows results in a "OSError: [Errno 13] Permission denied" error.
        * Bug fix for the scons clean target on MS Windows.  The build and dist directories from the Mac OS X py2app program are now only deleted by the clean_all target which checks for the paths.
        * Bug fix for a race condition on MS Windows blocking the test suite.  The analyses update_spin_count() call sets the value of the spin systems GUI element.  This is now via a wx.CallAfter() call to prevent the race in the GUI.
        * Bug fix for MS Windows - the user function menus are now fully deactivated during execution lock.  The submenus were strangely not all being deactivated, so now all submenu items are also deactivated.
        * Bug fix for the switching between analysis tabs on MS Windows.  The tab had not been changed when on_page_change() was being called (in contrast to GNU/Linux and Mac OS X).  Now wx.EVT_NOTEBOOK_PAGE_CHANGED is being used to bind the page change event rather than wx.EVT_NOTEBOOK_PAGE_CHANGING.
        * Bug fix for the structure.vectors user function back end, the check for already existing vector info now should work.
        * Fix for the results viewer window on MS Windows, the user functions now have the results viewer window set as the parent so that the window is not hidden by the main GUI window coming to the front.
        * Fix for the pipe editor window on MS Windows, the user functions now have the pipe editor window set as the parent so that the window is not hidden by the main GUI window coming to the front.
        * Fixes for the residue.create and spin.create user function GUI pages on MS Windows.  The default values are now correctly set.  This affects the pop up menu in the tree part of the spin viewer window.
        * Fixes for the user functions launched from the tree part of the spin viewer window on MS Windows.  The spin viewer window is now set as the parent, so that the main GUI window does not come to the front.
        * The user functions in the spin viewer window now have the parent window correctly set.  This is to help with an MS Windows window ordering bug.
        * Analysis tabs are now removed if the associated data pipe is deleted, avoiding nasty GUI crashing.
        * Fixes and improvements for the peak list wizards in the NOE and Rx auto-analyses.  The integration points page is now correctly set up.  And the spectrum ID is now only set if the field is blank, preventing a reversion of the user selected value.
        * The parent of the Question dialog in the pipe editor window is set so the window doesn't disappear.  Without this, the main GUI window comes to the front after the dialog is shown.
        * Fixes for the main GUI window moving in front of the spin viewer window.  The spin viewer window is now set as the parent for the Question dialogs, so that this window remains at the front.
        * Fixes for the residue user function GUI pages for when default values are sent to the page.  This fixes the user functions in the spin viewer window.
        * Fix for the new gui_to_str_or_list() function.
        * Bug fix for the structure.read_pdb GUI user function, the values from the GUI are now converted to the correct form.
        * Fix for the Help->Licence menu entry for the new GUI user function design, this additionally opens the relax controller window so the user will see the text.
        * Fixes for the pipe editor window to handle the new GUI user function design.
        * Fixes for the relaxation data reading GUI element for the new GUI user function design.
        * Fixes for some of the GUI user function calls from the tree part of the spin viewer window.
        * Fixes for the GUI user function launching in the model-free auto-analysis tab.
        * The spin viewer window now uses the full user function menu of the Uf_menus class, this should now remove the MS Windows bug whereby the spin viewer window would disappear to the back after closing of the user function wizard dialogs.
        * Fixes for the auto-analysis wizards for the new user function GUI page design.
        * Fixes for the GUI tests for the new design of the user function GUI pages.
        * Fix for the script user function GUI element for opening the file dialog.
        * Fixes for the relax controller, pipe editor and results viewer windows under MS Windows.  These windows were all dark grey, the default frame colour under MS Windows.  Now all elements are packed into a wx.Panel which sits inside the wx.Frame.
        * Added checks for a current data pipe to a number of GUI user function pages, this prevents relax errors when trying to launch the user functions but when no data pipes exist.
        * Fix for the MS Windows BAT file so that relax can be launched from the Windows PowerShell.
        * Fix for the dauvergne_protocol model-free auto-analysis with the deletion of data pipes.  Now only the data pipes created by dauvergne_protocol are deleted.  This fixes the problem whereby data pipes from other analyses are deleted by dauvergne_protocol, breaking the GUI.
        * Fix for the spin viewer window for MS Windows, the get_info() method now catches if no item is selected in the tree before trying to get the Python data from it.  Asking for Python data from a missing TreeCtrl item ID works on GNU/Linux and Mac OS X, but not on MS Windows.
        * Bug fix for MS Windows - the main relax window is now maximized upon start up.
        * Mac OS X fix for the relaxation data list element - the height algorithm is now more robust.  The ListCtrl.GetSize() method appears not to work on Mac OS X.  Therefore a different algorithm has been designed to get around this Mac specific problem.
        * Fix for the relax_fit.relax_time GUI user function.  The combobox GetValue() call has been replaced by GetStringSelection() for the spectrum ID.
        * Removed the wx.Yield() call from the spin viewer window refresh() method, this is to prevent recursive wx.Yield calls on Mac OS X from killing relax.
        * Fix for the Rx peak list wizard for Mac OS X, the combobox SetValue() call has been replaced with SetStringSelection().
        * Fix for the NOE spectrum loading wizard - the comboboxes need SetStringSelection rather than SetValue calls.  SetValue and GetValue on the read only combo boxes seems to fail on Mac OS X.
        * Mac OS X bug fix - the busy cursor is only turned off in the gui_raise window code if the busy cursor is on.
        * Mac OS X bug fix for racing in the GUI interpreter thread.  The flush() method was not working properly on Mac OS X, so hopefully now it is thread-safe.
        * Bug fix for Mac OS X for the spectrum.replicated GUI user function.  A GetValue() call fails on Mac OS X for a read only wx.ComboBox if no value is set.
        * Fix for the Rx auto-analysis GUI test for the changes to the spectrum.replicated user function GUI page.
        * Another Mac OS X test suite fix - the spin viewer window menu bar is now no longer set in the gui tests.
        * Bug fix for the test suite under Mac OS X - the GUI's SetMenuBar method is only called if status.show_gui is set.  This prevents the menu bar from starting when running the GUI tests.
        * Bug fix for Mac OS X - the timer in the relax controller is started with a wx.CallAfter() call.  This is to ensure that it will start from the main thread, which is essential.
        * All wx calls to Show(), ShowModal() and PopupMenu() are now suppressed if the status.show_gui flag is not set.  This is to eliminate problems of GUI elements starting up in the test-suite under Mac OS X.
        * Fixes for many user function GUI pages for when the apply button is clicked.  The combo box GUI elements were having data appended each time on_display() is called (this happens with a click on the apply button), but the previous values were not cleared out.  This results in very long repetitive lists.
        * Removed a recursive call to wx.Yield in the spin viewer window as this is fatal on Mac OS X.
        * Fixes for the spectrum.replicated user function GUI page for when the apply button is hit.  The spectrum IDs were continually appended to the ID boxes, so the lists could get quite long.
        * Fix for the model-free model changing question dialog in the dauvergne_protocol analysis.  The dialog is now larger to see all text, and the answer is no longer back to front.
        * Bug fixes for all of the specific analyses for running Monte Carlo simulations multiple times.  Many of the specific analyses were raising RelaxErrors if simulations had previously been run.  Now this no longer occurs, so that the analysis can be re-run which is important in GUI mode.
        * All of the major GUI and X freeze fixes have been ported to the relax data list.  The fixes for the spectrum list GUI element are now present in the relaxation data list GUI element as well, as the same problems occur in both code paths.
        * Fix for the size_cols() method of the spectrum list GUI element.  With the asynchronous updating of the element, sometimes the columns are not setup prior to a size_cols() call.
        * Bug fix for the freezing of X windows!  The spectrum list GUI element is now updated with a CallAfter() call so that the element is updated in a thread safe way.  Without this, the entire X windows system would sometimes freeze!
        * Bug fix for the freezing of the GUI.  The spectrum list GUI element was trying to update itself during execution lock, causing races if the spectrum data structures in the relax data store are being modified as the GUI element update is occurring.  This would result in a hard lock of the GUI.
        * Fix for the validate_sequence() function - the eval() calls raise all sorts of errors.
        * Fix for the reading of the sequence from generic formatted files with None in some of the columns.  This second problem is for the non-integer columns as the text 'None' was being interpreted as the name.
        * Fix for the reading of the sequence from generic formatted files with None in some of the columns.  The generic_fns.mol_res_spin.generate_spin_id_data_array() function now checks for when the data list contains 'None'.
        * Fix for the Rx peak height wizard, the user function flush flag was incorrectly named.
        * Fix for the wizard page _ok() method for the uf_flush flag.
        * Fix for the results viewer window file opening.
        * Fix for the results viewer window in testing mode - it is now not shown.
        * Fix for the pipe editor window - it is now updated when initially created to show all loaded pipes.
        * Fixes for all the calls to the GUI interpreter instance in the spin viewer window.  This is now a special thread object, and user function calls are now queued.
        * The auto-analysis GUI pages are now waiting for the data pipe to be created, fixing race conditions.
        * Some more fixes for the relax 'mode' class variable, these problems were due to the multi-processor code merger.
        * Fix for the GUI test mode - the mode variable should be a class variable.
        * Fix for the multi-processor code as the PrependOut class has been renamed to IO_filter.
        * Fixes for some of the file dialog wildcards.
        * Fix for the opening of Grace files via the results viewer.  It was being launched in both Grace and a text editor!
        * The spin viewer tree update() method now acquires both the pipe and spin locks, preventing a major source of race conditions.
        * The File menu entires for new or closing analyses or opening a state are blocked with the execution lock.  This is needed because the accelerator keys are still active, even if the menu entry is disabled (possibly a GTK bug).
        * The pipe editor window is now acquiring the pipe lock prior to updating its contents.  This removes a lot of race conditions, as the pipes can often change which the update occurs.
        * The execution lock is properly locked or released before notifying the observers.  This will remove some race conditions where the locked() method is called before the acquire() or release() methods terminate.
        * All wx object Append() calls now have their data passed through str_to_gui() first as well, this prevents GUI failures due to the wrong data type being encountered.
        * All data passed into wxPython SetValue() calls now go through gui.misc.*_to_gui() functions, this ensures that the correct data type is sent into the GUI elements.
        * Fix for the stereochemistry auto-analysis - the pipe_name argument does not exist in this auto-analysis.
        * Fix for the dauvergne_protocol - the maximum number of optimisation iterations is now an int.
        * The observers of pipe alterations should now all be thread safe, pipe changes in relax were causing segfaults in the GUI.
        * Fix for the dauvergne_protocol auto-analysis 'final' model.  The final stage of the dauvergne_protocol was broken.  The data pipes here need to be created rather than copied from the initial data pipe as results are being read into these pipes.
        * Fix for the dauvergne_protocol sample script - the mc_num argument is now called mc_sim_num.
        * Fix for the assemble_data() method of the NOE auto-analysis - the number of spectra can be less than 3.
        * Fix for the gui_to_float() for when an integer is given, it is now converted to a float.
        * Fix for the spectral list GUI element on Mac OS X, the ListCtrl.DeleteColumn() method is faulty on Mac OS X.  So instead all columns are deleted in one go, and then the entire thing is created on update.
        * Fixes for the results viewer window updating on Mac OS X.  The EVT_SHOW event was not being triggered by the frame's Show() method.
        * Bug fix for the dauvergne_protocol - the pipe.copy() calls are now followed by pipe.switch().  This is needed as previously the pipe.create() user function call automatically switched pipes, but pipe.copy() does not.
        * The results viewer window no longer fails if relax is still in the initial state.
        * Bug fix for the value.set user function page - the parameter rather than description is now used.  The description rather than parameter was being sent to the back-end.
        * Fix for the spin data check in the dauvergne_protocol auto-analysis - deselected spins are skipped.
        * Fix for the relaxation data check in the dauvergne_protocol auto-analysis.
        * Fix for Mac OS X - the wizard buttons are now all of the same size.  SetMinSize() rather than SetSize() needs to be used with wx.ADJUST_MINSIZE.
        * The dialog Close() rather than Destroy() method is being used to terminate the wizard, this is necessary for Mac OS X.
        * Mac OS X bug fit - removed the Destroy() call after ShowModal() in the wizard.  The Destroy() method was actually being called twice, the first time either by the _ok() or the _cancel() methods, and the second time directly after the ShowModal().  This is fatal on a Mac.

        N/A



Version 1.3.11
(12 August 2011, from /1.3)
http://svn.gna.org/svn/relax/tags/1.3.11

    Features:
        * Integration of relax and the BioMagResBank (BMRB, http://www.bmrb.wisc.edu).
        * Support for the creation of NMR-STAR version 3.1 files for BMRB deposition of model-free analysis results.
        * Support for the reading of all versions of NMR-STAR files containing model-free or relaxation data from the BMRB.
        * Use of the new bmrblib library for BMRB integration support (http://gna.org/projects/bmrblib).
        * Activated the PDC peak intensity type reading.
        * Added the Bruker PDC to the exp_info.software_select user function back end.
        * Implemented the value.set user function in the GUI.
        * Redesign of how relaxation data is handled within relax so that the data is identified via ID strings rather than relaxation type and frequency strings.
        * Added two sample scripts for determining the populations of an ensemble of small molecules.  This uses RDCs and PCSs with the N-state model to study the dynamics of small organic molecules (http://dx.doi.org/10.1002/chem.201100854).
        * The GUI can now be resized.
        * Big clean up and simplification of the GUI code resulting in a more regularised GUI on all operating systems.
        * Added initial support for determining protein connectivities in the internal structural reader.  This is currently only for intra-residue connectivities in the protein backbone.
        * Support for the reading of the organic chemistry XYZ 3D structure file format.

    Changes:
        * Removed the Numeric module from the --info print out as it is completely unused now.
        * Added the Bruker PDC software info to the exp_info module.
        * The pdc.read user function back end is now reading the PDC version information.
        * Added a catch for the "worst case per peak scenario" option in the PDC.  This will now throw a RelaxError, telling the user to go back to the PDC and use the other option.
        * Converted the pdc.read user function back-end to use the \t delimitation of the PDC file for parsing.
        * The R1 value and error are now being read directly from the PDC file.
        * Added wrapper methods to the relaxation curve-fitting specific code for the new C modules.  These allow the parameter numpy array from minfx to be converted into a Python list prior to sending it into the C module.
        * Added a check for the runpy Python module.
        * Scripts can now be run again under Python versions 2.4 or lower (by avoiding the runpy module).
        * The auto_analyses package modules are now imported by __init__ to force their existence.
        * The relax_data.back_calc user function arguments no longer need to be supplied.
        * Shifted all of the model-free sample scripts into the new subdirectory sample_scripts/model_free.
        * Added copyright headers to all of the sample scripts, and updated the introduction text.  This allows users to determine the age of the scripts.
        * Updated the OpenDX mapping sample scripts from the relax 1.2 to the 1.3 design.
        * Added a sample script for creating plots of experimental verses back calculated relaxation data.
        * Deleted the incomplete and useless N_state_model.py sample script.
        * Created a sample script subdirectory called n_state_model.
        * Added a sample script for the unsuccessful two domain N-state model optimisation.
        * Deleted the ancient TODO file, as it is no longer relevant.
        * Deleted the SRLS analysis type - there is no incentive to develop this part of relax.
        * Removed 'relax_disp' from the VALID_TYPES data pipe type array.  This is supported in the relaxation dispersion 'relax_disp' branch and not in the main line.
        * The RDC and PCS Q factor user functions now do nothing when data is missing rather than failing.  A warning is given and the function now simply returns rather than raising an error.
        * The grace file created by the pcs.corr_plot user function now separates each element into its own graph.
        * Converted the summary from the final_data_extraction.py sample script into comma separated file (.csv).
        * Added the PDB reading parts of Scientific python to relax so that Scientific python is no longer a relax dependency.
        * The Scientific python PDB reading tests are no longer skipped if the module is not installed.
        * Removed Scientific python and Numeric from the blacklisted modules.  This is for the docstring fetching script to generate the user function section of the user manual.
        * relax icon is not shown in window title if running on a Mac.
        * Included the relax development team to copyright statement in the main window of the GUI.
        * Peak lists and relaxation times are collected in data grids within the GUI.
        * Updated the Bieri et al., 2011 reference as the relax GUI paper is now published (http://dx.doi.org/10.1007/s10858-011-9509-1).
        * Changed the "Help->Contact relaxGUI" to "Help->Mailing list contact".
        * Renamed the "Relaxation time [s]" column to "Relaxation delay [s]" in the GUI as this is a more correct description.
        * Deleted Edward's ancient Melbourne Uni email address from the MEDLINE info.
        * Normalisation of the text in the auto model-free analysis GUI tab.  The font sizes are now all the same, the text is not right aligned (not seen under Linux but very ugly in Windows), and semicolon usage and capitalisation is normalised.
        * Regularisation of the font formatting in the steady-state NOE GUI tab.
        * Shifted the title and subtitle creation for the NOE frame into a base class for all frames to use.
        * Regularisation of the fonts, titles, and subtitles in the Rx auto-analysis frames.
        * Created the add_subsubtitle() base class method for creating a sub-sub-title in the GUI.
        * Regularised the text in the results tab.
        * Regularised the "Single delay cycle time [s]" text in the model-free frame.
        * Attempt to regularise the text in the text controls.
        * Regularised all the stead-state NOE frame text controls.
        * Created the add_static_text() base class method for all the GUI frames to use.
        * Added the add_button_open() base class method for regularising the buttons across GUI frames.
        * Regularised all of the auto NOE analysis frame buttons.
        * Added the add_text_sel_element() base class method for creating one of the basic frame elements.
        * Better layout for the base class static text, text control and button addition (for the GUI).
        * Added a stretchable spacer to the NOE window so the execute relax button is always at the bottom right.
        * Completely refactored the model-free model buttons code.
        * Shifted the model-free add_execute_relax() method into the base class for all analysis tabs to use.
        * The peak intensity GUI element is now enclosed within a StaticBox.
        * Shifted the main GUI window layout to the start of the __init__() method.
        * Created the function gui.misc.add_border() for adding borders to generic GUI elements.
        * Added an internal border to the relaxation peak list selection GUI element.
        * Created the analysis tab base class methods add_spin_control() and add_spin_element().  These are similar to the text control and text selection elements respectively, but use a SpinCtrl instead.
        * The model-free analysis tab now uses the base class add_spin_element() method for the max iterations.
        * Shifted the model-free list box in the results tab into the new add_list_box() method.
        * Shifted the 'Execute relax' text to be inside the button.
        * Added an icon to the 'Change' buttons throughout the GUI.
        * Added the oxygen icons for opening folders.
        * The open folder icons are now used for the 'Results directory' change buttons.
        * The settings windows are now derived from wx.Dialog rather than wx.Frame.  This is for better operation under MS Windows.
        * Added the document-close Oxygen icons.
        * Added support for old save files in the Peak_intensity.sync_ds() method (for the GUI).
        * Argument change_all for deselecting residues in the d'Auvergne protocol has to be boolean.
        * The relax_fit overfit_deselect() method now skips deselected spins.  This prevents unnecessary warnings about missing data for deselected spins.
        * All of the overfit_deselect() methods now skip deselected spins, avoiding confusing warnings.
        * Created a script for byte compiling the Python source files.
        * Added the data_type() method to the specific functions API.  This will be used to determine the type that a given parameter from data_names() should be.
        * Implemented the model-free version of the data_type() API method.
        * The heteronucleus and proton type parameters can now be specified by their parameter names as well.
        * The create_molecule, create_residue, and create_spin functions now return the created container.
        * Modified the create_spin() function to overwrite the first spin if empty.
        * Redesign of the structure.load_spins user function back end for XYZ file reading support.
        * Redesign of the main relax module.  The module has been renamed to 'relax.py', and the original file 'relax' is now a very basic python script which simply loads the module and runs the new start() function for launching relax.
        * The relax mode normally specified by the command line can now be overridden.
        * Removed the executable svn property on the info module.
        * Shifted the pedantic flag into the status object.
        * RelaxWarnings now only show a traceback when the pedantic flag is True.
        * The relax state is now saved on a RelaxError when the pedantic rather than debugging flag is turned on.  As both flags can be given, this allows for this state saving to be activated or deactivated.
        * The relax_io.read_spin_data() function no longer skips short lines so that a warning is given for it.
        * generic_fns.sequence.validate_sequence() now also checks for the spin ID, data and error columns.  This is now used by relax_io.read_spin_data().
        * Files created by the grace.write user function are now put into a new list cdp.results_files.
        * The value.write user function now also adds to the cdp.result_files structure.
        * Modified the execution lock to have a mode.  This allows for greater control and avoid string comparison of names to determine if a script or auto-analysis acquired the lock.
        * The dauvergne_protocol is now more robust if the program is interrupted and restarted later.  The opt/results.bz2 file is now searched for, and if not the round is assumed incomplete.
        * The pymol.tensor_pdb() user function now shows the diffusion tensor using PyMOL sticks.
        * Creation of the new structure.read_xyz user function.
        * Addition of two new system tests Structure.test_read_xyz_internal() and Structure.test_read_xyz_internal2().
        * Changing the description in the user functions structure.load_spins and structure.read_xyz.
        * Code for extracting a vector between specified spins in a XYZ file has been included in the generic_fns.structure.internal.
        * Debugging in the function generic_fns.structure.main.load_spin() in order to load a spin for XYZ file properly.
        * For printing out of modified spins, a test to check whether the spin_name exists or not has been added.
        * Added the pymol_macro() method to the analysis specific API.
        * Clean up of parameters in the _create_mc_relax_data() specific API common method.
        * A number of epydoc docstring fixes.
        * The sconstruct script is only executed when it is the main loaded module or if launched by scons.
        * Improved the list of modules and packages used in the epydoc documentation.  The files and directories which are not python modules or packages are now properly skipped.


    Bugfixes:
        * The setting of the integration method in the pdc.read user function now works.
        * Fixes for the pdc.read user function back-end for the NOE PDC file.
        * Fix for the pdc.read user function back-end for reading NOE data out of the new PDC files.
        * Fix for the relaxation curve-fitting back_calc_I C function so that it works under Python 2.5.
        * Fix for the initialisation of the Bruker_import class.  This allows this module to be loaded in Python 2.4.
        * The reference counting appears to not be needed in the C modules.  This allows the modules to be compiled under Python 2.4 or lower.
        * Loosened all of the model-free tests so that the minimisation statistics are no longer checked.  This will stop users from thinking they have a problem with their version of relax, after running the test suite.
        * Removed numpy from the relaxation curve-fitting C module code.  This should help with incompatibilities (and segfault failures) between different Python versions, as this seems to be due to the numpy C interface.
        * Improved the RelaxWarning for the reading of NMRView peaks with missing assignments (bug #17876).
        * Fix for the N-state model for when only the paramagnetic centre position is optimised.
        * Fix for the grid search limits as they were being scaled iteratively for each successive spin system (bug #18030).  This only affects certain type of custom grid searches.
        * A ":" symbol in the description of a function variable was preventing the compilation of the user manual using scons (bug #18037).
        * Opened files are closed properly after writing in the final_data_extraction.py sample script.
        * If no diffusion tensor is present, creation of diffusion pdb will be skipped (final_data_extraction.py sample script).
        * Updates for the Dasha sample script for the current version of relax.
        * Updates for the diffusion tensor optimization sample script for the current version of relax.
        * Some fixes for the subprocess.Popen() calls on MS Windows.
        * Removed event.skip due to conflict with Windows (auto-analysis Rx fix in the GUI).
        * Fixes for the spin.copy GUI user function element.  This still had remnants of the residue.copy window.
        * The relax icon is not shown in "Global relax settings" window if running on a Mac.  This fixes a bug whereby closing the window causes the GUI to crash.
        * Complete redesign of the relax global settings window to fix the Mac OS X crashing (bug #18197).
        * Fix for the global settings window - it needs to inherit from UF_window!
        * Fix for the NOE auto-analysis - the column numbers for the deselected spins file are now assumed.  The residue number is assumed to be in the first column.  This is a hack until the spin selection part is better designed.
        * Fix for the bug reported as sr #2764.  The problem was that the sequence file is now in the variable sequence_file.
        * Fix for the sequence.read user function - the force flag is now being passed on.
        * Fix for the sequence.write user function - the force flag is now passed to open_write_file().
        * Fix for the sequence.write user function when the column separator is not whitespace.  The column widths are no longer fixed if the separator is not whitespace.
        * Many bug fixes for the functions of the generic_fns.mol_res_spin module.  These fixes are for when a data pipe other than the current data pipe is used.
        * Fix for the relax save states - the current data pipe is now saved and restored.  The info about which pipe was the current one was being blacklisted, so was not stored in the relax save file.
        * Fix for the atomic position check in the spin.create_pseudo user function.
        * Fix for pseudo-atom support when only a single structure is loaded.  Pseudo-atom support was only working correctly for when multiple models were loaded and atomic positions were not averaged.
        * Fix for the spectrum.read_intensities user function int_method argument for volumes.  Volume integration should be called 'point sum', but the back end code was checking against the string 'volume'.
        * Fix in one of the relaxation curve-fitting system tests - 'volume' should have been 'point sum'.
        * Fix for the PCS back-calculation function - divide by zero is now avoided.  The function was calculating the normalised bond vector between the lanthanide atom and itself.  The normalisation in this case is now avoided.
        * Fix for the spectrum user functions for when the ID order does not match those loaded.  If the order of IDs sent to spectrum.replicated did not match the order they were loaded by spectrum.read_intensities, then the spectrum.error_analysis user function would fail.  The order is no longer important.
        * Fix - the pipe switching flag is now propagated all the way to the data store add() method.  The flag was previously not sent to the method so that the creation of a new data pipe always resulted in a switch to that pipe.  This bug is normally harmless.
        * Fix for the model-free _determine_model_type() method when the spin container has no 'local_tm'.  This code was failing in certain rare circumstances (when the setting up of the diffusion tensor was forgotten).
        * Fix for structure.read_pdb for when the file contains no PDB data.  This is now caught, and a warning is given and the function exists cleanly.
        * Fix for the RelaxWarning system on Mac OS X, the base class __str__ method now returns a simple string.  On a Mac, the warning message text was in unicode whereas the __str__() method must return a standard string.  So now __str__() is using the str() method to convert.
        * Fix for the structure.vectors user function.  It no longer complains about a PDB already loaded when no PDB has been loaded.
        * Fix for the resetting of the global optimisation round in the dauvergne_protocol auto-analysis.  The value was being reset to None at every round.
        * Fix for the round determination in the dauvergne_protocol auto-analysis.  The 'opt' directory was missing in the path.
        * Fix for the saving/loading of a results file in GUI mode.  The save files were containing the ds.relax_gui object and restoring it on loading.  This caused the data storage of the GUI to change underneath the GUI resulting in a crash or race conditions.
        * Fix for the resetting of the relax data store - the cdp structure is now set to None.  Previously the data store would be cleared, but the __builtin__.cdp structure would point to the old current data pipe, keeping it in existence and causing problems in the GUI.
        * Fix for the xydxdy type Grace graphs - the dx data was not being placed in the file.
        * Fix for the structure.create_diff_tensor_pdb user function for when no element info is available.  These atoms where the element is not in the PDB file or cannot be determined should have been skipped.
        * Fix for the molmol macro user functions - one of the args 'param' should have been 'data_type'.
        * Fix for the spin_loop() calls when generating Molmol macros.  The full_info argument should have been set to True.
        * Fix for the molmol.write macro creation user function - the file arg can be None!
        * Fix for the molmol.write user function for model-free parameters.  Some of the parameters were using the ancient self.relax code path which was eliminated with the redesign of relax 1.2 to 1.3.
        * Fixes for the old scripts/optimisation_testing.py script.  This was also using the ancient self.relax code path.
        * Fix for the molmol macro of the ts parameter, the spin container variable was spelt incorrectly.
        * Fix for the data.align_tensor.calc_eta() function - divide by zeros are now avoided.  When Azz is zero, eta is now set to NaN.
        * Typo fix in the unused and incomplete dfunc function to remove compilation warnings on MS Windows.
        * Fix for the data.align_tensor.calc_R() function - divide by zeros are now avoided.  When Aa is zero, Ar is now set to NaN.
        * Fix for the test_opt_constr_bfgs_mt_S2_0_970_te_2048_Rex_0_149 model-free system test on MS Windows.  The te parameter check was too strict.
        * Another divide by zero problem is being caught in the RDC Q-factor code.
        * The dipolar_constant() and pcs_constant() functions now catch division by zero problems.

        * Fix for running scripts in certain versions of python - if a file with the same name as the script lies in one of the paths in sys.path, then that file will be executed rather than the script.



Version 1.3.7
(10 January 2011, from /1.3)
http://svn.gna.org/svn/relax/tags/1.3.7

    Features:
        * Shifted the relax installation path variable from __main__ into the status singleton object, allowing relax modules to be imported outside of relax.
        * Shifted the global relax debug flag from __main__.debug to the relax status singleton, allowing the flag to be defined even when imported from outside of relax.

    Changes:
        * Speed up of the relaxation curve-fitting system tests.
        * The sample_scripts/full_analysis.py script has been renamed to sample_scripts/dauvergne_protocol.py.
        * Improvements to the test suite final print out with a table of skipped tests.
        * The data pipe system test is avoiding the frame order data pipe, allowing the test to pass without scipy installed.
        * The alignment tensor system test now uses the N-state model rather than frame order so it is always tested.
        * The frame order system and unit tests are skipped if scipy is not installed.
        * The frame order analysis is disabled if scipy is not installed.
        * The data pipe generic code now uses dep_check to see if the relaxation curve-fitting is available.
        * The system tests now use the RelaxTestLoader to allow tests to be skipped.
        * The unit vector system tests using scientific python are now being skipped if the package is not installed.
        * The structure system tests involving scientific python are now skipped if the package is not installed.
        * The RelaxTestLoader has been added as a replacement for unittest.TestLoader to handle the skipping of tests when optional Python packages are not installed.
        * Shifted the status singleton instantiation to the import level in all modules, saving execution time.
        * Big code cleanups in unit_test_runner.py

    Bugfixes:
        * Peak intensity errors can now be calculated when using volume integration and replicated spectra (bug #17457).
        * Failure of the prolate diffusion tensor in model-free analysis - if the tensor is initialised with Da = 0, the tensor is converted to being oblate.  This was introduced in relax version 1.3.6.
        * relax can now operate without scipy being installed.
        * Updated four model-free optimisation system tests to pass under 32-bit Linux.
        * Made the N_state_model.test_pcs_fit_zero_pos system test less stringent so it passes on 32-bit Linux.
        * The model_free _model_setup() method should handle no model-free model being set when reading relax 1.2 results files (bug #17417).



Version 1.3.6
(31 December 2010, from /1.3)
http://svn.gna.org/svn/relax/tags/1.3.6

    Features:
        * Addition of Michael Bieri's model-free data extraction script.
        * Added support for CCPN Analysis 2.1 peak lists (exported in Sparky format).
        * Execution locking has been implemented to prevent threaded execution from killing relax.  This will be useful for the relax GUI.
        * Scripts are now run as modules rather than using execfile(), closing a security hole.
        * Created the frame_order.domain_to_pdb() user function to associate PDB files with domains in the current data pipe.
        * Rewrote frame_order.cone_pdb() to handle all of the frame order models.
        * The sign of the RDC can be inverted to correct for the negative 15N gyromagnetic ratio.
        * Better identification of the molecule end in the internal PDB reader.
        * Implemented Monte Carlo simulations for the N-state model.
        * The grid_search() user function argument incs can now be a list with None elements to fix parameters.
        * Expanded the number of frame order models to include the 'free rotor', 'rigid', 'rotor', 'iso cone, free rotor', 'iso cone, torsionless', 'iso cone', 'pseudo-ellipse, free rotor', 'pseudo-ellipse, torsionless', and 'pseudo-ellipse'.
        * Pre-defined probabilities can now be used in the 'fixed' N-state model optimisation.
        * The Ln3+ position can be directly optimised in the N-state models.
        * The pcs.back_calc() user function now does something.
        * Created the n_state_model.elim_no_prob() to remove structures with zero probability.
        * Created the align_tensor.fix() user function for fixing the alignment tensor during optimisation.
        * The alignment tensor optimisation is now optional within the population N-state model target fn.
        * The RDCs and PCSs can now be given optimisation weights.
        * Per point comments are now included in the Grace files.
        * The RDC and PCS correlation plots now also show the experimental errors.
        * The RDC and PCS back-calculation user functions now add the alignment ID to the RDC and PCS if absent to allow both data types to be back-calculated in the absence of measured data.
        * The N-state model calculate() method now stores the back-calculated RDCs and PCSs and Q factors.
        * The PyMOL module pymol.cmd is now available within the pymol user function class, accessible as pymol.cmd from the prompt/script interface.

    Changes:
        * API documentation improvements with epydoc docstring fixes.
        * Numerous new system tests to catch bugs and prevent bugs appearing in the future.
        * Peak intensity data is now internally handled differently to improve its flexibility.  This will be beneficial for handling Bruker PDC (Protein Dynamic Center) files, relaxation dispersion data, and adding new types of relaxation data.
        * The 'scons clean' target now removes temporary relax save files.
        * The molecule type can now be specified.
        * Improved the diffusion tensor print out.
        * pipe.delete() without args will now delete all data pipes.
        * Added some checks to the dauvergne_protocol model-free analysis for the required previously optimised results.
        * Shifted the steady-state NOE specific analysis code into its own package.
        * Shifted the debug and pedantic flags into the __main__ namespace for better access from other modules.
        * Modified the specific code API to remove a number of references to spin_id, as not all analyses use spins.
        * Renamed the results_folder arg to results_dir in the NOE auto-analysis, and rearranged the args.
        * Citations now include the status if not 'published'.
        * Created a new directory 'graphics' for all relax artwork.
        * The structure.load_spins() user function now gives a RelaxWarning if no data could be found.
        * The negative cones and z-axes are now not created for the pseudo-ellipses in frame_order.cone_pdb().
        * Added some transparency to the cone in pymol.cone_pdb().
        * Modified the pymol.cone_pdb() user function to handle x, y, and z-axes.
        * Modified create_cone_pdb() to accept a pre-made structural object and to create a file only when asked.
        * Switched the names of the Pseudo_elliptic and Pseudo_elliptic2 classes.
        * Created a API common specific code set_selected_sim() method for a single global model.
        * Created a API common specific code model_loop() method for a single global model.
        * All objects placed into the relax data store structure are now stored in the XML save file.
        * Parameters can be fixed to the original values during the frame order grid search.
        * The user function argument checker arg_check.is_int_or_int_list() can now allow for None list elements.
        * The frame order model can be overwritten by frame_order.select_model().
        * Shifted to using numpy.sinc() for the frame order equations.
        * Switched the theta and phi angles in cartesian_to_spherical() to match the rest of relax.
        * Created a new module for performing coordinate transformations (maths_fns.coord_transform).

        * Initialising an alignment tensor now adds the ID to the alignment ID list.
        * Changes to the NOE auto-analysis for the GUI:  The output filename can be specified;  The folder, where results files will be placed, can be specified;  The label of heteronucleus and proton of peak lists and PDB file can be selected;  The sequence is read either by sequence file or PDB file;  Removed white spaces and progress output.

        * Fix for the average domain rotation in pymol.cone_pdb().
        * Bug fix for the frame_order.pivot() user function - it is now functional.

        * Small fixes and improvements to the rdc.back_calc() user function - align IDs are being used instead of RDC IDs so RDCs can be back-calculated even if measured RDCs are not present.  And spin info is also being checked for better error reporting to the user.
        * Fix for the alignment tensor rotation matrix - it is now always in the right handed universe.
        * Bug fix for the RDC back_calc() function - the align_id arg was being ignored.
        * Fix for the RDC back_calc() function for when N=1 in the N-state model, the bond vector structure was not correct.
        * Fixes for the N-state model target function setup for when no parameters are optimised.

        * Redesign of the spin.create() and residue.create() user functions - respectively residue and molecule names and numbers are used instead of the res_id and mol_id arguments, allowing residues and molecules to be created as needed.
        * Modified the full_analysis.py script to perform 500 Monte Carlo simulations and turned on automatic looping.
        * Support for non-identical sequences in different PDB files within the same data pipe (only as different molecules, not different models).
