Thank you so much Eric for helping me. Let me tell you what I have done before this:
- I have done the search with *TMT 10 plex of K* and *TMT 10plex of N term* fixed residue modification in *X!Tandem*. The Enzyme was Trypsin. I set the mass modification in X!Tandem as: - <note label="residue, modification mass" type="input">229.1629@K,229.1629@[</note> - Then I converted the results of X! Tandem to pep.xml (Using Tandem2XML) - Next I got the probabilities with the following setting: - PeptideProphetParser 1607011A_NC20A_10ul_180min.tandem.pep.xml ACCMASS PPM NOICAT MINPROB=0.05 and then I wanted to convert the result to splib that I encountered this error. The modifications that spectrast gives me did not make sense to me too. Do you have any idea what might have happened here? I am going to redo the search to see if anything changes. Thanks again!
