EasyPQP: Simple library generation for OpenSWATH
EasyPQP is a Python package that provides simplified and fast peptide query parameter generation for OpenSWATH. It can process input from MSFragger or other database search engines in pepXML format. Statistical validation can be conducted either using PyProphet or PeptideProphet/iProphet. Retention times are calibrated using an internal or external standard. In addition to a cumulative library, run-specific libraries are generated for non-linear RT alignment in OpenSWATH. For generation of PTM specific libraries that utilizes a unimod.xml database, you can further restrict the unimod.xml database file for modifications and site-specificities of interest.
