NAME

       Bio::AlignIO::xmfa - XMFA MSA Sequence input/output stream

SYNOPSIS

       Do not use this module directly.  Use it via the Bio::AlignIO class.

DESCRIPTION

       This object can transform Bio::SimpleAlign objects from XMFA flat file databases.  For
       more information, see:

         http://asap.ahabs.wisc.edu/mauve-aligner/mauve-user-guide/mauve-output-file-formats.html

       This module is based on the AlignIO::fasta parser written by Peter Schattner

TODO

       Finish write_aln(), clean up code, allow LargeLocatableSeq (e.g. for very large sequences
       from Mauve).

FEEDBACK

   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.

        Function: returns the next alignment in the stream.
        Returns : Bio::Align::AlignI object - returns 0 on end of file
                   or on error
        Args    : -width => optional argument to specify the width sequence
                  will be written (60 chars by default)

       See Bio::Align::AlignI

   write_aln
        Title   : write_aln
        Usage   : $stream->write_aln(@aln)
        Function: writes the $aln object into the stream in xmfa format
        Returns : 1 for success and 0 for error
        Args    : L<Bio::Align::AlignI> object

       See Bio::Align::AlignI

   _get_len
        Title   : _get_len
        Usage   :
        Function: determine number of alphabetic chars
        Returns : integer
        Args    : sequence string

   width
        Title   : width
        Usage   : $obj->width($newwidth)
                  $width = $obj->width;
        Function: Get/set width of alignment
        Returns : integer value of width
        Args    : on set, new value (a scalar or undef, optional)
