NAME
Bio::Tools::Run::Match - Wrapper for Transfac's match(TM)
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;

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

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address
it. Please include a thorough description of the problem with code and data examples if at all possible.

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
