Hello, I've been searching SILAC data using X!Tandem within the TPP.
Everything works fine until I try to analyze my PeptideProphet hits
with ProteinProphet.  I noticed that other people were having similar
problems with data from Bioworks and it was solved by moving the the
fasta database from the dbase folder to the database folder.  However,
in my case this did not help.  Also, I had to change a lot of settings
in the X!Tandem default file before I could get the database search to
work.  Is it possible that my params file would have something to do
with this.

Thanks for your help.

I get the following error message:
