Multiple Engine Proteomics Search Workflow
PEAKS inChorus combines the multiple engine proteomics search results from Mascot, X!Tandem, OMSSA, and Proteome Discoverer (Sequest). It can call Mascot, X!Tandem, and OMSSA directly and the results are automatically retrieved and combined by PEAKS inChorus.
Multiple engine proteomics search results are displayed in a unified interface (Figure 2), with the engine icons indicating which engine or engines identified the same peptide-spectrum match (PSM). A blue background indicates that the engine assigned a higher-than-threshold score to the corresponding PSM and a white background indicates the score is lower than threshold from that engine.
