NAME

Bio::Tools::Run::Match - Wrapper for Transfac’s match(TM)

CONTENTS

SYNOPSIS



  use Bio::Tools::Run::Match;

  # Make a Match factory
  $factory = Bio::Tools::Run::Match->new(-mxlib => /path/to/matrix.dat);

  # Run Match on an sequence object
  my @results = $factory->run($bio_seq);

  # look at the results
  foreach my $feat (@results) {
    my $seq_id = $feat->seq_id;
    my $start = $feat->start;
    my $end = $feat->end;
    my $score = $feat->score;
    my ($pvalue) = $feat->get_tag_values(pvalue);
  }



DESCRIPTION

This is a wrapper for running the match(TM) program supplied with Transfac Pro distributions.

You can try supplying normal match command-line arguments to new(), eg. new(-b => 1) or calling arg-named methods (excluding the initial hyphens, eg. $factory->b(1) to set the -b option to true).

Histogram output isn’t supported. -p is supported by using -mxprf, see the docs of new() for details.

You will need to enable this match wrapper to find the match executable. This can be done in (at least) three ways:



 1. Make sure match is in your path.
 2. Define an environmental variable MATCHDIR which is a
    directory which contains the match executable:
    In bash:

    export MATCHDIR=/home/username/match/

    In csh/tcsh:

    setenv MATCHDIR /home/username/match

 3. Include a definition of an environmental variable MATCHDIR in
    every script that will use this match wrapper module, e.g.:

    BEGIN { $ENV{MATCHDIR} = /home/username/match/ }
    use Bio::Tools::Run::Match;

Please direct usage questions or support issues to the mailing list:

APPENDIX

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

    program_name



 Title   : program_name
 Usage   : $factory>program_name()
 Function: holds the program name
 Returns : string
 Args    : None



    program_dir



 Title   : program_dir
 Usage   : $factory->program_dir(@params)
 Function: returns the program directory, obtained from ENV variable.
 Returns : string
 Args    : None



    new



 Title   : new
 Usage   : $factory = Bio::Tools::Run::Match->new()
 Function: creates a new MCS factory
 Returns : Bio::Tools::Run::MCS
 Args    : The following args can either be supplied here or set by calling
           arg-named methods (eg. $factory->imcut(2) ).

           -mxlib  => path to the matrix.dat file containing Transfac matricies
           -mxprf  => path to a profile file | [core_thresh, [matrix_thresh]]
                      (defaults to a standard one based on the mxlib provided if
                      file not supplied, using core_thresh and matrix_thresh
                      values if those are supplied instead)
           -imcut  => floating point number, the importance cutoff
           -b | -u => boolean, mutually exclusive



    run



 Title   : run
 Usage   : $result = $factory->run($bio_seqi_object);
 Function: Runs match on a sequence.
 Returns : list of Bio::SeqFeatureI feature objects
 Args    : Bio::SeqI compliant object

           NB: mxlib has to have been set prior to calling run(), either as an
           argument to new() or by calling mxlib().



    _setparams



 Title   : _setparams
 Usage   : Internal function, not to be called directly
 Function: Creates a string of params to be used in the command string
 Returns : string of params
 Args    : none
