NAME

       Bio::SeqIO::phd - phd file input/output stream

SYNOPSIS

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

DESCRIPTION

       This object can transform .phd files (from Phil Green's phred basecaller) to and from
       Bio::Seq::Quality objects. The phd format is described in section 10 at this url:
       http://www.phrap.org/phredphrap/phred.html

   Support
       Please direct usage questions or support issues to the mailing list:

       bioperl-l@bioperl.org

       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.
