Mascot Server 2.8.3 patch release

Mascot Server 2.8.3 has been released. This patch fixes six small bugs in the search engine (nph-mascot.exe), four in Mascot Perl scripts, one in ms-monitor.exe regarding a spurious log message and one issue with licensing on AMD EPYC processors.

We recommend all users to install the update. The cumulative update from 2.8.0, 2.8.1 and 2.8.2 can be downloaded from the support page.

  • 14038: Chimeric spectrum peaklist with some dodgy precursors causes Mascot to crash almost immediately
  • 14095: ShowSubSets in is probably broken in 2.8.1
  • 14105: Crash from chimeric spectra MGF when decoy selected
  • 14142: Scoring of N-terminal and C-terminal crosslinks occasionally too low, caused by fragment mass miscalculation when linking terminus to residue
  • 14189: Can’t call method “resetKeepAlive” on an undefined value at ./ line 667.
  • 14246: MaxConcurrentSearches not respected evenly on the master and the node
  • 14270: “Prepare ../taxonomy/acc_to_taxid.mapping.txt_*.cdb” even though nothing needs to be done
  • 14291: Disulfide crosslink search hangs at 67% due to number of open filehandles
  • 14340: Executable aborts immediately on AMD EPYC 7763 if creating an ms_processors object
  • 14366: xiView column CalcMz calculated using a hydrogen rather than a proton
  • 14367: Prevent PMF with Big Mascot
  • 14403: Peptide View reports C-terminal modification on wrong residue
