Bio::SeqIO::agave(3pm)

NAME

Bio::SeqIO::agave - AGAVE sequence output stream.

SYNOPSIS

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

  $in  = Bio::SeqIO->new('-file'   => "$file_in",
                         '-format' => 'EMBL');
  $out = Bio::SeqIO->new('-file'   => ">$file_out",
                         '-format' => 'AGAVE');
  while (my $seq = $in->next_seq){
        $out->write_seq($seq);
  }

DESCRIPTION

This object can transform Bio::Seq objects to agave xml file and vice-versa. I (Simon) coded up this module because I needed a parser to extract data from AGAVE xml to be utitlized by the GenQuire genome annotation system (See http://www.bioinformatics.org/Genquire).

***NOTE*** At the moment, not all of the tags are implemented. In general, I followed the output format for the XEMBL project http://www.ebi.ac.uk/xembl/
