PTPredict

This application is used to predict the likelihood of peptides to be proteotypic.

This method has been described in the publication

Ole Schulz-Trieglaff, Nico Pfeifer, Clemens Gröpl, Oliver Kohlbacher and Knut Reinert LC-MSsim - a simulation software for Liquid ChromatographyMass Spectrometry data BMC Bioinformatics 2008, 9:423.

The input of this application is an svm model and an idXML file with peptide identifications. The svm model file is specified by the svm_model parameter in the command line or the ini file. This file should have been produced by the PTModel application.

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:

    PTPredict -- predicts the likelihood of peptides to be proteotypic via svm_model which is trained by PTModel

    Usage:

      PTPredict <options>

    Options (mandatory options marked with '*'):

      -in <file>*                    Input file  (valid formats: 'idXML')

      -out <file>*                   Output file

                                     (valid formats: 'idXML')

      -svm_model <file>*             Svm model in libsvm format (can be produced by PTModel) (valid formats: 'txt

                                     ')

      -max_number_of_peptides <int>  The maximum number of peptides considered at once (bigger number will lead

                                     to faster results but needs more memory).

                                     (default: '100000')

    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)
