IDConflictResolver

Resolves ambiguous annotations of features with peptide identifications.

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.

resolve_between_featuresoff A map may contain multiple features with both identical (possibly modified i.e. not stripped) sequence and charge state. The feature with the 'highest intensity' is very likely the most reliable one. When switched 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) sequence maintain annotated with this peptide sequence.off, highest_intensity
