The peptide identifications are filtered so that only one identification with a single hit (with the best score) is associated to each feature. (If two IDs have the same best score, either one of them may be selected.)
The the filtered identifications are added to the vector of unassigned peptides and also reduced to a single best hit.
This step may be useful before applying ProteinQuantifier, because features with ambiguous annotation are not considered for the quantification.

IDConflictResolver -- Resolves ambiguous annotations of features with peptide identifications Full documentation: http://www.openms.de/doxygen/release/3.2.0/html/TOPP_IDConflictResolver.html Version: 3.2.0 Nov 18 2024, 16:14:00, Revision: 03223c3 To cite OpenMS: + Pfeuffer, J., Bielow, C., Wein, S. et al.. OpenMS 3 enables reproducible analysis of large-scale mass spec trometry data. Nat Methods (2024). doi:10.1038/s41592-024-02197-7. Usage: IDConflictResolver <options> Options (mandatory options marked with '*'): -in <file>* Input file (data annotated with identifications) (val id formats: 'featureXML', 'consensusXML') -out <file>* Output file (data with one peptide identification per feature) (valid formats: 'featureXML', 'consensus XML') -resolve_between_features <resolve_between_features> A map may contain multiple features with both identic al (possibly modified i.e. not stripped) sequence and charge state. The feature with the 'highest inten sity' is very likely the most reliable one. When swit ched on, the filter removes the sequence annotation from the lower intensity features, thereby resolving the multiplicity. Only the most reliable features for each (possibly modified i.e. not stripped) sequen ce maintain annotated with this peptide sequence. (default: 'off') (valid: 'off', 'highest_intensity') Common TOPP options: -ini <file> Use the given TOPP INI file -threads <n> Sets the number of threads allowed to be used by the TOPP tool (default: '1') -write_ini <file> Writes the default configuration file --help Shows options --helphelp Shows all options (including advanced)
