Bio::Tools::Run::Meme

NAME

Bio::Tools::Run::Meme − Wrapper for Meme Program

SYNOPSIS

  use Bio::Tools::Run::Meme;
  my $factory = Bio::Tools::Run::Meme−>new(−dna => 1, −mod => 'zoops');
  # return a Bio::AlignIO given Bio::PrimarySeqI objects
  my $alignio = $factory−>run($seq1, $seq2, $seq3...);
  # add a Bio::Map::Prediction to the appropriate maps given Bio::Map::GeneMap
  # objects (predict on the full map sequences supplied) or Bio::Map::Gene
  # objects (predict on the full map sequences of the maps the supplied Genes
  # are on) or Bio::Map::PositionWithSequence objects
  my $prediction = $factory−>run($biomap1, $biomap2, $biomap3...);

DESCRIPTION

This is a wrapper for running meme, a transcription factor binding site prediction program. It can be found here: http://meme.sdsc.edu/meme4/meme−download.html

You can try supplying normal meme command-line arguments to new(), eg. new(−mod => ’oops’) or calling arg-named methods (excluding the initial hyphen(s), eg. $factory−>mod(’oops’) to set the −mod option to ’oops’).

You will need to enable this MEME wrapper to find the meme program. During standard installation of meme you will have set up an environment variable called MEME_BIN which is used for this purpose.

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

new

 Title   : new
 Usage   : $rm−>new($seq)
 Function: creates a new wrapper
 Returns:  Bio::Tools::Run::Meme
 Args    : Most options understood by meme can be supplied as key =>
           value pairs, with a boolean value for switches. −quiet can also be
           set to silence meme completely.
           These options can NOT be used with this wrapper (they are handled
           internally or don't make sense in this context):
           −h −text −nostatus

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    :

version

 Title   : version
 Usage   : n/a
 Function: Determine the version number of the program, which is
           non−discoverable for Meme

run

 Title   : run
 Usage   : $rm−>run($seq1, $seq2, $seq3...);
 Function: Run Meme on the sequences/Bio::Map::* set as the argument
 Returns : Bio::AlignIO if sequence objects supplied, OR
           Bio::Map::Prediction if Bio::Map::* objects supplied
           undef if no executable found
 Args    : list of Bio::PrimarySeqI compliant objects, OR
           list of Bio::Map::GeneMap objects, OR
           list of Bio::Map::Gene objects, OR
           list of Bio::Map::PositionWithSequence objects

_run

 Title   : _run
 Usage   : $rm−>_run ($filename,$param_string)
 Function: internal function that runs meme
 Returns : as per run(), undef if no executable found
 Args    : the filename to the input sequence file
