NAME - Filters the matches of a .peptSpectra.xml file

SYNOPSIS [options] peptSpectra.xml


Use -h


The script filters the matches of a .peptSpectra.xml file by applying several possible criteria.

It is possible to impose a maximum parent ion mass error in Daltons or in ppm.

It is possible to restrict the matches to an imposed charge states.

It is possible to impose a minimum number of peaks in the experimental fragmentation spectra, either an absolute number or a number relative to the average number of amino acids (by supposing an average mass of 100 Da).

When several criteria are used simultaneously, then the selected peptides must satisfy them all.
