A Search Result (aka ResultSet in the database schema) is the raw interpretation of a given set of MS/MS spectra given by a search engine or a de novo interpretation process. It contains one or many peptides matching the submitted MS/MS spectra (PSM, i.e. Peptide Spectrum Match), and the protein sequences these peptides belong to. The Search Result also contains additional information such as search parameters, used protein sequence data-bank, etc.

A Search Result is created when a resultfile (Mascot .dat file or an OMSSA .omx) file is imported in Proline. In the case of a target-decoy search, two Search Results are created: one for the target PSMs, one for decoy PSMs.

Importing a resultfile creates a new Search Result in the database which contains the following informations:

• Search Settings : software name and version, parameters values
• Peak List and Spectrum information : file name, ms-level, precursor moz, …
• Search result data:
  • Proteins
  • Peptide
  • Spectrum
  • 2 type of Matches
    • a Peptide Match is a match between a peptide and a spectrum, with score, fragment matches …
    • a Protein Matches is a match between a peptide and a protein

The peptide matches score correspond to Mascot ion score
