Multi-Engine DB: inChorus
PEAKS inChorus currently can combine results from Mascot, X!Tandem, OMSSA, and Proteome Discoverer (Sequest). It can call Mascot, X!Tandem, and OMSSA directly within PEAKS GUI and the results are automatically retrieved and combined by PEAKS inChorus.
All the peptides from different engines 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.
