   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.

APPENDIX

       The rest of the documentation details each of the object methods.  Internal methods are
       usually preceded with a _

   next_seq
        Title   : next_seq
        Usage   : $seq = $stream->next_seq()
        Function: returns the next sequence in the stream
        Returns : Bio::Seq object
        Args    :

   write_seq
        Title   : write_seq
        Usage   : $stream->write_seq($seq)
        Function: writes the $seq object into the stream
        Returns : 1 for success and 0 for error
        Args    : Array of Bio::PrimarySeqI objects

   write_qual
        Title   : write_qual
        Usage   : $stream->write_qual($seq)
        Function: writes the $seq object into the stream
        Returns : 1 for success and 0 for error
        Args    : Bio::Seq::Quality object

   variant
        Title   : variant
        Usage   : $format  = $obj->variant();
        Function: Get and set method for the sequence variant.  For raw sequence, this
                  indicates whether to treat the input as multiple sequences (the
                  default) or as a single sequence.

                  Current values accepted are:

                   'single'    single sequence
                   'multiple'  multiple sequences (default)
        Returns : string
        Args    : new value, string
