PSM Rescoring

Performs rescoring of peptide spectrum matches based on score distributions of targets and decoys (IDPEP) or multiple peptide features (Percolator). Output are the same PSMs with a new main score (Posterior Error Probability, where lower scores are better and scores are roughly comparable across search engines).

Input ports

1. Type: Table
   idXML(s)
   List of idXMLs with PSMs (usually directly from search engines)

Output ports

1. Type: Table
   rescored idXML(s)
