PSMFeatureExtractor computes extra features for each input PSM
- Experimental classes:
- Parts of this tool are still work in progress and usage and input requirements or output might change. (multiple_search_engine, Mascot support)
PSMFeatureExtractor is search engine sensitive, i.e. it's extra features vary, depending on the search engine. Thus, please make sure the input is compliant with TOPP SearchengineAdapter output. Also, PeptideIndexer compliant target/decoy annotation is mandatory. Currently supported search engines are Comet, X!Tandem, MSGF+. Mascot support is available but in beta development.
- Note
- if you have extra features you want to pass to percolator, use the extra flag and list the MetaData entries containing the extra features.
The command line parameters of this tool are:
PSMFeatureExtractor -- Computes extra features for each input PSM.

Usage:
PSMFeatureExtractor <options>
Options (mandatory options marked with '*'):
-in <files>* Input file(s) (valid formats: 'idXML', 'mzid')
-out <file>* Output file in mzid or idXML format (valid formats: 'idXML', 'mzid')
-out_type <type> Output file type -- default: determined from file extension or content. (valid
: 'idXML', 'mzid')
-extra <MetaData parameter> List of the MetaData parameters to be included in a feature set for precolator
.
-multiple_search_engines Combine PSMs from different search engines by merging on scan level.
Common UTIL options:
-ini <file> Use the given TOPP INI file
-threads <n> Sets the number of threads allowed to be used by the TOPP tool (default: '1')
-write_ini <file> Writes the default configuration file
