Comet 2023.01 rev. 0 is now available.
  • Address issue where a peptide with a low xcorr identified in a very poor/sparse spectrum would be assigned a good E-value. This is due to the majority of matched xcorr scores being "0" so any poor scoring match looks like a good outlier.  Thanks to D. Shteynberg for reporting the issue.
  • Add "scale_fragmentNL" parameter entry which scales (multiplies) the neutral loss mass value by the number of modified residues in the fragment. Feature requested by A. Keller.
  • Add contributions of fragment neutral loss peaks in preliminary (Sp) score; previously they only applied to the cross-correlation score.
  • Correct bug where the fragment neutral loss peak was not analyzed if the primary fragment peak was not matched.
  • Fix minor typo in command line help. Thanks to M. Riffle for contributing the fix.
