Bio::AlignIO::clustalw - clustalw sequence input/output stream
Do not use this module directly. Use it via the Bio::AlignIO class.
This object can transform Bio::Align::AlignI objects to and from clustalw files.
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.
