X! Tandem

X! Tandem is open source software that can match tandem mass spectra with peptide sequences. X! tandem generates theoretical spectra for peptide sequences using information about intensity associated with amino acids. These spectra are compared with experimental data to generate an expectation value as a threshold score.

X!tandem has been installed on Galaxy-P (http://galaxyp.msi.umn.edu ) suite of tools and on TINT (https://tint.msi.umn.edu) for proteomics searches.
