The PFR Annotator node assigns PFR Accessions to proteoforms that pass the FDR threshold in the ProSightPD FDR node. Only proteoforms associated with a protein entry and a Taxon Id will be annotated. If the search result is associated with multiple Taxon Ids, PFR Accessions will not be assigned.
The PFR Annotator node adds a column to the proteoform results table, which includes a proteoform reference number (PFR). The PFR lets you track proteoforms across different experiments.
The PFR Annotator node does not have parameters.
