Using X!Tandem and the TPP
This page is intended to give instructions for various ways of working with X!Tandem and the TPP. Currently, we continue to refine the PeptideProphet models for X!Tandem-Kscore.
current state
While X!Tandem data will run through the pipeline without error, results are non-optimal. Also, we do not yet support X!Tandem in the GUI.
- native Tandem is supposed to work with TPP, but results are quite bad
- using K-score plugin (included in TPP cygwin distrubtion, also avaliable from CPAS site will work much better
- proceed at your own risk if they use the more sophisticated Tandem features (e.g. some refinement options) because PeptideProphet may not work with them.
