So far an estimation of the false score distribution with a gamma distribution and the correct score distribution with a gaussian distribution is performed. The probabilities are calculated using Bayes law, similar to PeptideProphet. This implementation is much simpler than that of PeptideProphet.
The command line parameters of this tool are:
