ExMS-CL peptide analysis

Script to analyze output from ExMS-CL

ExMS-CL is a program that can be used to identify oxidatively modified and unmodified peptides from an x-ray footprinting experiment followed by non-specific pepsin digestion of the protein.
The output of ExMS-CL is the input of this program. This program takes the idenitified peptides and their modified/un-modified counts and calculates oxidation rates for each peptide.
