Bio::SeqIO::GenBank - GenBank sequence input/output stream
It is probably best not to use this object directly, but rather go through the SeqIO handler system. Go:
$stream = Bio::SeqIO->new(-file => $filename, -format => 'GenBank'); while ( my $seq = $stream->next_seq() ) { # do something with $seq }
This object can transform Bio::Seq objects to and from GenBank flat file databases.
There is alot of flexibility here about how to dump things which I need to document fully.
This section is supposed to document which sections and properties of a GenBank databank record end up where in the Bioperl object model. It is far from complete and presently focuses only on those mappings which may be non-obvious. $seq in the text refers to the Bio::Seq::RichSeqI implementing object returned by the parser for each record.
$seq->primary_id
(output only) shows the dna or not
(output only) provides a sorting func which is applied to the FTHelpers before printing
This is function which is called as
print "ID ", $func($seq), "\n";
To generate the ID line. If it is not there, it generates a sensible ID line using a number of tools.
If you want to output annotations in genbank format they need to be stored in a Bio::Annotation::Collection object which is accessible through the Bio::SeqI interface method annotation().
The following are the names of the keys which are polled from a Bio::Annotation::Collection object.
reference - Should contain Bio::Annotation::Reference objects comment - Should contain Bio::Annotation::Comment objects

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : next_seq Usage : $seq = $stream->next_seq() Function: returns the next sequence in the stream Returns : Bio::Seq object Args :
Title : write_seq Usage : $stream->write_seq($seq) Function: writes the $seq object (must be seq) to the stream Returns : 1 for success and 0 for error Args : array of 1 to n Bio::SeqI objects
Title : _print_GenBank_FTHelper Usage : Function: Example : Returns : Args :
Title : _read_GenBank_References Usage : Function: Reads references from GenBank format. Internal function really Returns : Args :
Title : _read_GenBank_Species Usage : Function: Reads the GenBank Organism species and classification lines. Example : Returns : A Bio::Species object Args : a reference to the current line buffer
Title : _read_FTHelper_GenBank Usage : _read_FTHelper_GenBank($buffer) Function: reads the next FT key line Example : Returns : Bio::SeqIO::FTHelper object Args : filehandle and reference to a scalar
Title : _write_line_GenBank Usage : Function: internal function Example : Returns : Args :
Title : _write_line_GenBank_regex Usage : Function: internal function for writing lines of specified length, with different first and the next line left hand headers and split at specific points in the text Example : Returns : nothing Args : file handle, first header, second header, text-line, regex for line breaks, total line length
Title : _post_sort Usage : $obj->_post_sort($newval) Function: Returns : value of _post_sort Args : newvalue (optional)
