mwfilter
Function
Description
mwfilter is designed to remove unwanted (noisy) data from mass
spectrometry output in proteomics. Given a list of molecular weights
this program removes those which are:
- Contaminating trypsin or keratin
- Modified oxy-methionine or oxy-threonine
- Peaks associated with sodium ions.
The last two operations can be done as most peaks are reported in
both modified and unmodified forms. Removal of modified peaks
aids in database searching for protein identification.
Usage
Command line arguments
Input file format
The input file is a simple list of the experimental molecular weights.
There should be one weight per line.
Comments in the data file start with a '#' character in the first column.
Blank lines are ignored.
Output file format
The output is a list of the molecular weights with the unwanted (noisy)
data removed.
Data files
The program reads the data file Emwfilter.dat for the molecular
weights of items to be deleted from the experimental data.
