OpenMS
IDMergerAlgorithm Class Reference

Creates a new Protein ID run into which other runs can be inserted. Creates union of protein hits but concatenates PSMs. Checks search engine consistency of all inserted runs. It differs from the IDMerger tool, in that it is an algorithm class and it allows inserting multiple peptide hits per peptide sequence (not only the first occurrence). More...

Detailed Description

Creates a new Protein ID run into which other runs can be inserted. Creates union of protein hits but concatenates PSMs. Checks search engine consistency of all inserted runs. It differs from the IDMerger tool, in that it is an algorithm class and it allows inserting multiple peptide hits per peptide sequence (not only the first occurrence).

Todo:
allow filtering for peptide sequence to supersede the IDMerger tool. Make it keep the best PSMs though.
