NAME¶
Bio::NexmlIO - stream handler for NeXML documents
SYNOPSIS¶
#Instantiate a Bio::Nexml object and link it to a file
my $in_nexml = Bio::Nexml->new(-file => 'nexml_doc.xml', -format => 'Nexml');
#Read in some data
my $bptree1 = $in_nexml->next_tree();
my $bpaln1 = $in_nexml->next_aln();
my $bpseq1 = $in_nexml->next_seq();
#Use/manipulate data
...
#Write data to nexml file
my $out_nexml = Bio::Nexml->new(-file => '>new_nexml_doc.xml', -format => 'Nexml');
$out_nexml->to_xml();
DESCRIPTION¶
Bio::NexmlIO is an I/O handler for a NeXML document. A NeXML document can represent three different data types: simple sequences, alignments, and trees. NexmlIO has four main methods next_tree, next_seq, next_aln, and write. NexmlIO returns bioperl seq, tree, and aln objects which can be manipulated then passed to the write method of a new NexmlIO instance to allow the creation of a NeXML document.
Each bioperl object contains all the information necessary to recreate a Bio::Phylo::Taxa object, so each time a bioperl object is converted to a biophylo object, the bioperl object is checked to see if its associated taxa has already been created (against a hash using the NexmlIO_ID and Taxa_ID to create a unique string). If not, it is created; if so, that taxa object is used to link the Bio::Phylo tree or matrix.
For more information on the NeXML format, see <http://www.nexml.org>.
FEEDBACK¶
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.

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.

CONSTRUCTOR¶
new¶
Title : new Usage : my $in_nexmlIO = Bio::NexmlIO->new(-file => 'data.nexml.xml'); Function: Creates a L<Bio::NexmlIO> object linked to a stream Returns : a L<Bio::NexmlIO> object Args : file name See L<Bio::Root::IO>
doc¶
Title : doc Usage : my $nexml_doc = $in_nexmlIO->doc(); Function: returns a L<Bio::Phylo::Project> object that contains all the Bio::Phylo data objects parsed from the stream Returns : a L<Bio::Phylo::Project> object Args : none
ITERATORS¶
next_tree¶
Title : next_tree Usage : $tree = $stream->next_tree Function: Reads the next tree object from the stream and returns it. Returns : a L<Bio::Tree::Tree> object Args : none
See Bio::Root::IO, Bio::Tree::Tree
next_seq¶
Title : next_seq Usage : $seq = $stream->next_seq Function: Reads the next seq object from the stream and returns it. Returns : a L<Bio::Seq> object Args : none
See Bio::Root::IO, Bio::Seq
next_aln¶
Title : next_aln Usage : $aln = $stream->next_aln Function: Reads the next aln object from the stream and returns it. Returns : a L<Bio::SimpleAlign> object Args : none
See Bio::Root::IO, Bio::SimpleAlign
rewind_seq¶
Title : rewind_seq Usage : $stream->rewind_seq Function: Resets the stream for seqs Returns : none Args : none
See Bio::Root::IO, Bio::Seq
rewind_aln¶
Title : rewind_aln Usage : $stream->rewind_aln Function: Resets the stream for alns Returns : none Args : none
See Bio::Root::IO, Bio::Simple::Align
rewind_tree¶
Title : rewind_tree Usage : $stream->rewind_tree Function: Resets the stream for trees Returns : none Args : none
See Bio::Root::IO, Bio::tree::tree
write¶
Title : write
Usage : $stream->write(-alns => $alns,-seqs => $seqs,-trees => $trees)
Function: converts BioPerl seq, tree, and aln objects into Bio::Phylo
seq, tree, and aln objects, constructs a Bio::Phylo::Project
object made up of the newly created Bio::Phylo objects, and
writes the Bio::Phylo:Project object to the stream as a valid
nexml document
Returns : none
Args : \@L<Bio::Seq>, \@L<Bio::SimpleAlign>, \@L<Bio::Tree::Tree>
See Bio::Root::IO, Bio::tree::tree, Bio::Seq, Bio::SimpleAlign
extract_seqs¶
Title : extract_seqs
Usage : $nexmlIO->extract_seqs(-file => ">$outfile", -format => $format)
Function: converts BioPerl seqs stored in the NexmlIO object into the provided
format and writes it to the provided file. Uses L<Bio::SeqIO> to do
the conversion and writing.
Returns : none
Args : file to write to, format to be converted to
See Bio::Seq, Bio::SeqIO
extract_alns¶
Title : extract_alns
Usage : $nexmlIO->extract_alns(-file => ">$outfile", -format => $format)
Function: converts BioPerl alns stored in the NexmlIO object into the provided
format and writes it to the provided file. Uses L<Bio::AlignIO> to do
the conversion and writing.
Returns : none
Args : file to write to, format to be converted to
See Bio::SimpleAlign, Bio::AlignIO
extract_trees¶
Title : extract_trees
Usage : $nexmlIO->extract_trees(-file => ">$outfile", -format => $format)
Function: converts BioPerl trees stored in the NexmlIO object into the provided
format and writes it to the provided file. Uses L<Bio::TreeIO> to do
the conversion and writing.
Returns : none
Args : file to write to, format to be converted to
