What is X!Tandem?

X!Tandem is an open-source (and free) search engine, developed by the GPM.

What is the K-Score?

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.

Running X!Tandem

Someone could contribute info on setting up the params file for Tandem here..

Converting X!Tandem data for the TPP

Please see warnings in "current status" section above.

Tandem2XML is used to convert Tandem results into pepXML. Please see that page for instructions.
