Bio::AlignIO::po - po 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 '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).
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.
Report bugs to the Bioperl bug tracking system to help us keep track the bugs
and their resolution. Bug reports can be submitted via the web:
