+**What it does**
+
+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.
