mwcontam

Function

Description

mwcontam finds molecular weights that are common between a set of mass spectrometry result files. Such molecular weights are usually a form of contamination resulting from autolysis of a protease, degradation of the matrix or presence of keratin from the sample preparer.

The output of mwcontam, with minimal editing, can be added to the data file for the mwfilter program ('Emwfilter.dat').

Usage

Command line arguments


Input file format

The input is a comma-separated list of files containing simple list of 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 common to all files.

Data files

mwcontam uses no data files.

The output of mwcontam, with minimal editing, can be added to the data file for the mwfilter program ('Emwfilter.dat'). For example you might like to fetch 'Emwfilter.dat' using embossdata (as described in the mwfilter documentation) and edit it to include the lines:


# data produced from the program mwcontam
mwcontam	67.000
mwcontam	415.000
