PEAKS (software)

Overview[edit | edit source]

PEAKS is a software program for tandem mass spectrometry designed for peptide sequencing and protein identification.

Description[edit | edit source]

PEAKS can be used for search engine protein identification (Protein ID) and for de novo sequencing (both automated and manual) and peptide sequence tag based searching. (SPIDER).^{[citation needed]}

PEAKS provides a complete sequence for each peptide, confidence scores on individual amino acid assignments, simple reporting for high-throughput analysis, and other information.

The software has the ability to compare results. PEAKS will cross check test results automatically with other protein ID search engines, like Sequest, OMSSA, X!Tandem and Mascot. This approach guards against false positive peptide assignments. Template:WH Template:WS
