Command line implementation
X! tandem open source is software that can match tandem mass spectra with peptide sequences, in a process that has come to be known as protein identification.

This software has a very simple, unsophistocated application programming interface (API): it simply takes an XML file of instructions on its command line, and outputs the results into an XML file, which has been specified in the input XML file.
X! Tandem MS Protein Sequence Modeler is available for download by clicking one of the links above.

This version of X! tandem is a pre-release, only including source level documentation. As more releases occur, better documentation will be included.
