Bio::SeqIO::pir - PIR sequence input/output stream


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


This object can transform Bio::Seq objects to and from pir flat file databases.

Note: This does not completely preserve the PIR format - quality information about sequence is currently discarded since bioperl does not have a mechanism for handling these encodings in sequence data.
