NAME
Bio::SeqIO::chaos - chaos sequence input/output stream SYNOPSIS
#In general you will not want to use this module directly; #use the chaosxml format via SeqIO $outstream = Bio::SeqIO->new(-file => $filename, -format => 'chaosxml'); while ( my $seq = $instream->next_seq() ) { $outstream->write_seq($seq); } DESCRIPTION
This is the guts of Bio::SeqIO::chaosxml - please refer to the documentation for this module CURRENTLY WRITE ONLY ChaosXML is an XML mapping of the chado relational database; for more information, see http://www.fruitfly.org/chaos-xml chaos can be represented in various syntaxes - XML, S-Expressions or indented text. You should see the relevant SeqIO file. You will probably want to use Bio::SeqIO::chaosxml, which is a wrapper to this module. USING STAG OBJECTS non-standard bioperl stuff you don't necessarily need to know follows This module (in write mode) is an event producer - it generates XML events via the Data::Stag module. If you only care about the final end- product xml, use Bio::SeqIO::chaosxml You can treat the resulting chaos-xml stream as stag XML objects; $outstream = Bio::SeqIO->new(-file => $filename, -format => 'chaos'); while ( my $seq = $instream->next_seq() ) { $outstream->write_seq($seq); } my $chaos = $outstream->handler->stag; # stag provides get/set methods for xml elements # (these are chaos objects, not bioperl objects) my @features = $chaos->get_feature; my @feature_relationships = $chaos->get_feature_relationships; # stag objects can be queried with functional-programming # style queries my @features_in_range = $chaos->where('feature', sub { my $featureloc = shift->get_featureloc; $featureloc->strand == 1 && $featureloc->nbeg > 10000 && $featureloc->nend < 20000; }); foreach my $feature (@features_in_range) { my $featureloc = $feature->get_featureloc; printf "%s [%d->%d on %s] ", $feature->sget_name, $featureloc->sget_nbeg, $featureloc->sget_end, $featureloc->sget_srcfeature_id; } MODULES REQUIRED

Mailing Lists 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. bioperl-l@bioperl.org - General discussion http://bioperl.org/wiki/Mailing_lists - About the mailing lists Support 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. Reporting Bugs Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _ context_namespace Title : context_namespace Usage : $obj->context_namespace($newval) Function: Example : Returns : value of context_namespace (a scalar) Args : on set, new value (a scalar or undef, optional) IDs will be preceded with the context namespace next_seq Title : next_seq Usage : $seq = $stream->next_seq() Function: returns the next sequence in the stream Returns : Bio::Seq object Args : write_seq 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 : Bio::Seq perl v5.14.2 2012-03-02 Bio::SeqIO::chaos(3pm)
