PEAKS is a proteomics software program for tandem mass spectrometry designed for peptide sequencing, protein identification and quantification.
Description
PEAKS is commonly used for peptide identification (Protein ID) through de novo peptide sequencing assisted search engine database searching.[1] PEAKS has also integrated PTM and mutation characterization through automatic peptide sequence tag based searching (SPIDER)[2] and PTM Identification.[3]
PEAKS provides a complete sequence for each peptide, confidence scores on individual amino acid assignments, simple reporting for high-throughput analysis, amongst other information.
The software has the ability to compare results of multiple search engines. PEAKS inChorus 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.
PEAKS Q is a plugin quantification tool, supporting label (ICAT, iTRAQ, SILAC, TMT, O18, etc.) and label free techniques. Performance evaluation of existing de novo sequencing algorithms. ABRF 2013 iPRG Study results.
