Function

This module is for cross-species protein identifications using searches against NCBInr, for example. MASCOT processing uses BUDAPEST. Hits are then converted into peptides for redundancy removal. Hits from a given (known) query species are preferentially kept and any peptides belonging to those hits are purged from hits returned by other species. All hits are then classified: - UNIQUE : Contains 2+ peptides, including 1+ unique peptides - NR : Contains 2+ peptides; None unique but 1+ peptides only found in other "NR" proteins - REDUNDANT : Contains 2+ peptides but all found in proteins also containing UNIQUE peptides - REJECT : Identified by <2 peptides once query-species peptides subtracted
