X! Tandem must be installed before this wrapper can be used. This wrapper has been successfully tested with several versions of X! Tandem. The last known version to work is 2009-04-01. We encountered problems with later versions (namely 2010-01-01).

To speed up computations, FASTA databases can be compressed using the fasta_pro.exe tool of X! Tandem. It is contained in the "bin" folder of the X! Tandem installation. Refer to the docu of X! Tandem for further information about settings.

This adapter supports relative database filenames, which (when not found in the current working directory) is looked up in the directories specified by 'OpenMS.ini:id_db_dir' (see TOPP for Advanced Users).

X! Tandem settings not exposed by this adapter can be directly adjusted using an XML configuration file. By default, all (!) parameters available explicitly via this wrapper take precedence over the XML configuration file. The parameter "default_config_file" can be used to specify such a custom configuration. An example of a configuration file (named "default_input.xml") is contained in the "bin" folder of the X! Tandem installation and the OpenMS installation under OpenMS/share/CHEMISTRY/XTandem_default_input.xml. The latter is loaded by default. If you want to use the XML configuration file and ignore most of the parameters set via this adapter, use the '-ignore_adapter_param' flag. Then, the config given in '-default_config_file' is used exclusively and only '-in', '-out', '-database' and '-xtandem_executable' are taken from this adapter.

Note
Currently mzIdentML (mzid) is not directly supported as an input/output format of this tool. Convert mzid files to/from idXML using IDFileConverter if necessary.

The command line parameters of this tool are:
