Bio::AlignIO::xmfa(3)

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 (ie for very large sequences a'la Mauve)
