SYNOPSIS

# A simple annotation pipeline wrapper for ePCR data
# assuming ePCR data is already generated in file seq1.epcr
# and sequence data is in fasta format in file called seq1.fa
use Bio::Tools::EPCR;
use Bio::SeqIO;
my $parser = Bio::Tools::EPCR->new(-file => 'seq1.epcr');
my $seqio = Bio::SeqIO->new(-format => 'fasta', -file => 'seq1.fa');
my $seq = $seqio->next_seq || die("cannot get a seq object from SeqIO");
while( my $feat = $parser->next_feature ) {
# add EPCR annotation to a sequence
$seq->add_SeqFeature($feat);
}
my $seqout = Bio::SeqIO->new(-format => 'embl');
$seqout->write_seq($seq);

DESCRIPTION

This object serves as a parser for ePCR data, creating a Bio::SeqFeatureI for each ePCR hit. These can be processed or added as annotation to an existing Bio::SeqI object for the purposes of automated annotation.

Mailing Lists

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

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 _

new

 Title   : new
 Usage   : my $epcr = Bio::Tools::EPCR->new(-file => $file,
                                           -primary => $fprimary, 
                                           -source => $fsource, 
                                           -groupclass => $fgroupclass);
 Function: Initializes a new EPCR parser
 Returns : Bio::Tools::EPCR
 Args    : -fh   => filehandle
           OR
           -file => filename
           -primary => a string to be used as the common value for
                       each features '-primary' tag.  Defaults to
                       'sts'.  (This in turn maps to the GFF 'type'
                       tag (aka 'method')).
            -source => a string to be used as the common value for
                       each features '-source' tag.  Defaults to
                       'e-PCR'. (This in turn maps to the GFF 'source'
                       tag)
             -groupclass => a string to be used as the name of the tag
                           which will hold the sts marker namefirst
                           attribute.  Defaults to 'name'.

next_feature

 Title   : next_feature
 Usage   : $seqfeature = $obj->next_feature();
 Function: Returns the next feature available in the analysis result, or
           undef if there are no more features.
 Example :
 Returns : A Bio::SeqFeatureI implementing object, or undef if there are no
           more features.
 Args    : none

source

 Title   : source
 Usage   : $obj->source($newval)
 Function: 
 Example : 
 Returns : value of source (a scalar)
 Args    : on set, new value (a scalar or undef, optional)

primary

 Title   : primary
 Usage   : $obj->primary($newval)
 Function: 
 Example : 
 Returns : value of primary (a scalar)
 Args    : on set, new value (a scalar or undef, optional)

groupclass

 Title   : groupclass
 Usage   : $obj->groupclass($newval)
 Function: 
 Example : 
 Returns : value of groupclass (a scalar)
 Args    : on set, new value (a scalar or undef, optional)
