NAME

       Bio::AlignIO::po - po 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 to and from 'po' format flat file
       databases. 'po' format is the native format of the POA alignment program (Lee C, Grasso C,
       Sharlow MF, 'Multiple sequence alignment using partial order graphs', Bioinformatics
       (2002), 18(3):452-64).
