ms2rescore 3.1.5

MS²Rescore: Sensitive PSM rescoring with predicted MS² peak intensities and retention times.

Modular and user-friendly platform for AI-assisted rescoring of peptide identifications

About MS²Rescore

MS²Rescore performs ultra-sensitive peptide identification rescoring with LC-MS predictors such as MS²PIP and DeepLC, and with ML-driven rescoring engines Percolator or Mokapot. This results in more confident peptide identifications, which allows you to get more peptide IDs at the same false discovery rate (FDR) threshold, or to set a more stringent FDR threshold while still retaining a similar number of peptide IDs. MS²Rescore is ideal for challenging proteomics identification workflows, such as proteogenomics, metaproteomics, or immunopeptidomics.

MS²Rescore can read peptide identifications in any format supported by psm_utils (see Supported file formats) and has been tested with various search engines output files:

• MS Amanda .csv
• Sage .sage.tsv
• PeptideShaker .mzid
• ProteomeDiscoverer.msf
• MSGFPlus .mzid
• Mascot .mzid
• MaxQuant msms.txt
• X!Tandem .xml
• PEAKS .mzid

MS²Rescore is available as a desktop application, a command line tool, and a modular Python API.

TIMS²Rescore: Direct support for DDA-PASEF data

MS²Rescore v3.1+ includes TIMS²Rescore, a usage mode with specialized default configurations for DDA-PASEF data from timsTOF instruments. TIMS²Rescore makes use of new MS²PIP prediction models for timsTOF fragmentation and IM2Deep for ion mobility separation. Bruker .d and miniTDF spectrum files are directly supported through the timsrust library.
