Experimental classes:: This util is deprecated and might behave not as expected!

So far an estimation of the false score distribution with a gamma distribution and the correct score distribution with a gaussian distribution is performed. The probabilities are calculated using Bayes law, similar to PeptideProphet. This implementation is much simpler than that of PeptideProphet.

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:

IDDecoyProbability -- Estimates peptide probabilities using a decoy search strategy.

Usage:
  IDDecoyProbability <options>

This tool has algorithm parameters that are not shown here! Please check the ini file for a detailed descript
ion or use the --helphelp option

Options (mandatory options marked with '*'):
  -in <file>         Identification input of combined forward decoy search (reindex with PeptideIndexer first
                     ) (valid formats: 'idXML')
  -fwd_in <file>     Identification input of forward run (valid formats: 'idXML')
  -rev_in <file>     Identification input of decoy run (valid formats: 'idXML')
  -out <file>*       Identification output with forward scores converted to probabilities (valid formats: 
                     'idXML')
                     
                     
Common TOPP 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
  --help             Shows options
  --helphelp         Shows all options (including advanced)

The following configuration subsections are valid:
 - decoy_algorithm   Algorithm parameter subsection

You can write an example INI file using the '-write_ini' option.
Documentation of subsection parameters can be found in the doxygen documentation or the INIFileEditor.
