Bio::AlignIO::metafasta - Metafasta MSA Sequence input/output stream
Do not use this module directly. Use it via the Bio::AlignIO class.
This object can transform Bio::SimpleAlign objects to and from metafasta flat file databases.
The format of a metafasta file is
>test/1-25 ABCDEFHIJKLMNOPQRSTUVWXYZ &charge NBNAANCNJCNNNONNCNNUNNXNZ &chemical LBSAARCLJCLSMOIMCHHULRXRZ
where the sequence block is followed by one or several meta blocks. Each meta block starts with the ampersand character '&' in the first column and is immediately followed by the name of the meta data which continues until the new line. The meta data follows it. All characters, except new line, are important in meta data.
Please direct usage questions or support issues to the mailing list:
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.

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : next_aln Usage : $aln = $stream->next_aln() Function: returns the next alignment in the stream. Returns : L<Bio::Align::AlignI> object - returns 0 on end of file or on error Args : NONE
Title : write_aln Usage : $stream->write_aln(@aln) Function: writes the $aln object into the stream in fasta format Returns : 1 for success and 0 for error Args : L<Bio::Align::AlignI> object
Title : width Usage : $obj->width($newval) Function: Get/Set the line width for METAFASTA output Returns : value of width Args : newvalue (optional)
