39 **What it does**
40
41 Given raw search engine scores as inputs this tool estimates the accuracy of peptide assignments. From a practical perspective it estimates the probability that each peptide assignment is correct (providing probabilities as outputs), given raw scores (possibly on some arbitrary scale) as inputs.

60 m [maldi data]
61 I [use pI information in PeptideProphet]
62 R [use Hydrophobicity / RT information in PeptideProphet]
