Purpose: Improve the separation of target and decoy identifications in proteomics data sets in order to boost the confidence in search results.
Methods: Several datasets were analysedusing a beta version of Thermo Scientific™ Proteome Discoverer™ 2.5 software with SequestHTand the new Prosit-derived (1) Rescoring node by MSAID.
Results: Deep-learning-based prediction of fragment ion intensities enables the addition of intensity-based scores to identification workflows with SequestHT, which increase the confidence in search results.
