Summary

Bio::SeqIO::flybase_chadoxml - FlyBase variant of chadoxml with sequence output stream

Package variables

Inherit

Bio::SeqIO::chadoxml

Synopsis

It is probably best not to use this object directly, but
rather go through the SeqIO handler system:

    $writer = Bio::SeqIO->new(-file => ">chado.xml",
                              -format => 'flybase_chadoxml');

    # assume you already have Sequence or SeqFeature objects
    $writer->write_seq($seq_obj);

    #after writing all seqs
    $writer->close_chadoxml();

Description

This is a simple subclass of Bio::SeqIO::chadoxml; please see
its documentation for details.

Methods

Methods description

 Title    : return_ftype_hash
 Usage    : $obj->return_ftype_hash()
 Function : A simple hash where returning it has be factored out of the main
            code to allow subclasses to override it.
 Returns  : A hash that indicates what the name of the SO term is and what
            the name of the Sequence Ontology is in the cv table.
 Args     : The string that represents the SO term.
 Status   :

 Title    : return_reltypename
 Usage    : $obj->return_reltypename
 Function : Return the appropriate relationship type name depending on the
            feature type (typically part_of, but derives_from for polypeptide).
 Returns  : A relationship type name.
 Args     : A SO type name.
 Status   :

 Title   : write_seq
 Usage   : $stream->write_seq(-seq=>$seq, -seq_so_type=>$seqSOtype,
                  -src_feature=>$srcfeature,
                  -src_feat_type=>$srcfeattype,
                  -nounflatten=>0 or 1,
                  -is_analysis=>'true' or 'false',
                  -data_source=>$datasource)
 Function: writes the $seq object (must be seq) into chadoxml.
 Returns : 1 for success and 0 for error
 Args     : A Bio::Seq object $seq, optional $seqSOtype, $srcfeature,
            $srcfeattype, $nounflatten, $is_analysis and $data_source.

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.
