You will need some other support tool(s) to actually make use of Comet results (A GUI for Windows only is available). It takes in spectra in some supported input format and writes out. Note that Comet is just a single command line binary that does MS/MS database search. CHIMERYS is developed by MSAID GmbH, a spin-off from the Technical University of Munich and is integrated as node in Proteome Discoverer 3.0 software.ĭatabase search algorithm developed at the University of Washington available for Windows and Linux. Next-generation, cloud-native database search algorithm for data-dependent acquisition data which makes heavy use of artificial intelligence for the identification of peptides and the deconvolution of chimeric spectra.

with original developments at PARC that searches MS/MS data from all types of instruments and internally employs the program Combyne, which combines peptide identifications to produce protein scores and identification probabilities. ĭatabase search algorithm released in 2011 by Protein Metrics Inc. Developed by Jürgen Cox and others at the Max Planck Institute of Biochemistry. Identification of co-fragmented peptides improves the number of identified peptides. This combination enables analysis of large datasets on a desktop computer. Andromeda can function independently or integrated into MaxQuant.

It can handle data with arbitrarily high fragment mass accuracy, it is able to assign and score complex patterns of post-translational modifications, such as highly phosphorylated peptides, and accommodates extremely large databases. On proteome data, Andromeda performs as well as Mascot, a widely used commercial search engine, as judged by sensitivity and specificity analysis based on target decoy searches. The former search takes place against a database containing all amino acid sequences assumed to be present in the analyzed sample, whereas the latter infers peptide sequences without knowledge of genomic data.Īndromeda is a peptide search engine based on probabilistic scoring. Peptide identification algorithms fall into two broad classes: database search and de novo search. In protein mass spectrometry, tandem mass spectrometry (also known as MS/MS or MS 2) experiments are used for protein/ peptide identification. Further information: protein mass spectrometry
