Sequest, by Thermo Sciences, is a search engine that matches tandem mass spectra with peptide sequences. LabKey Server uses Sequest to search an mzXML file against a FASTA database and displays the results in the MS2 viewer for analysis.

 

Because LabKey Server can search with several different search engines, a common format was chosen for entering search parameters. The format for the search parameters is based on the input.xml format, developed for X!Tandem. LabKey Server includes a set of default Sequest search parameters. These default parameters can be overwritten on the search form.
