Synopsis
 use Bio::Matrix::PSM::IO;
 #Obtain an Bio::Matrix::PSM::IO object:
 my $psmIO= Bio::Matrix::PSM::IO->new(-file=>$file, -format=>'mast');

 #Get some general data about the file you are parsing:
 my $release=$psmIO->release;
 my $version=$psmIO->version;

 print "This analysis was performed using MAST version $version, release $release\n";

 #Now let's see what are the consensus sequences of the motifs fed as an input:
 my %seq=$psmIO->seq;

 #let's cycle through all consensus sequences now:

 foreach my $id ($psmIO->hid) {
   print "Motif $id is \t",$seq{$id},"\n";
 }

  #Finally look at the stuff we do not parse:
  my @inputfile=grep(/datafile/i,$psmIO->unstructured);
Description
Generally you should not use this object directly, you can access the
information through a PSM driver (See Bio::Matrix::PSM::IO). It is
handling the header data from a PSM file which may be very
different. This means that some of the methods will return undef
naturally, because this information is not present in the file which
is parsed. Some important data might be left over in the unstructured
part, and you might have to parse it yourself. I will try to
'structure' this header more in the near future.

seqcode    nextTop
 Title   : seq
 Usage   : my %seq= $header->seq();
 Function: Returns the sequence data as a hash, indexed by a 
           sequence ID (motif id or accession number)
           In case the input data is a motif it would return the 
           consenus seq for each of them (mast).
 Throws  :
 Example :
 Returns :  hash
 Args    :
hidcodeprevnextTop
 Title   : hid
 Usage   : my @ids= $header->hid();
 Function: Returns array with the motif/instance ids
 Throws  :
 Example :
 Returns :  array
 Args    :
lengthcodeprevnextTop
 Title   : length
 Usage   : my %length= $header->length();
 Function: Returns the length of the input sequence or motifs as a hash, indexed
           by a sequence ID (motif id or accession number)
 Throws  :
 Example :
 Returns :  hash
 Args    :
instancescodeprevnextTop
 Title   : instances
 Usage   : my %instances= $header->length();
 Function: Returns the instance, used  as a hash, indexed
           by a sequence ID (motif id or accession number)
 Throws  :
 Example :
 Returns :  hash of Bio::Matrix::PSM::InstanceSite objects
 Args    :
weightscodeprevnextTop
 Title   : weights
 Usage   : my %weights= $header->weights();
 Function: Returns the weights of the input sequence as a hash, indexed
           by a sequence ID
 Throws  :
 Example :
 Returns :  hash
 Args    :
versioncodeprevnextTop
 Title   : version
 Usage   : my $version= $header->version;
 Function: Returns the version of the file being parsed if such exists
 Throws  :
 Example :
 Returns :  string
 Args    :
revisioncodeprevnextTop
 Title   : revision
 Usage   : my $revision= $header->revision;
 Function: Returns the revision of the file being parsed if such exists
 Throws  :
 Example :
 Returns :  string
 Args    :
_checkcodeprevnextTop
 Title   : _check
 Usage   : if ($self->_check('weights') { #do something} else {return 0;}
 Function: Checks if the method called is aplicable to the file format
 Throws  :
 Example :
 Returns :  boolean
 Args    :  string

Mailing ListsTop
User feedback is an integral part of the evolution of this
and other Bioperl modules. Send your comments and suggestions preferably
to one of the Bioperl mailing lists.
Your participation is much appreciated.

Support Top
Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
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.
