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 formatted $seq object into the stream
Returns : 1 for success and 0 for error
Args    : array of Bio::PrimarySeqI object

GCG_checksum

Title     : GCG_checksum
Usage     : $cksum = $gcgio->GCG_checksum($seq);
Function  : returns a gcg checksum for the sequence specified

            This method can also be called as a class method.
Example   :
Returns   : a GCG checksum string
Argument  : a Bio::PrimarySeqI implementing object

_validate_checksum

Title   : _validate_checksum
Usage   : n/a - internal method
Function: if parsed gcg sequence contains a checksum field
        : we compare it to a value computed here on the parsed
        : sequence. A checksum mismatch would indicate some
        : type of parsing failure occurred.
        :
Returns : 1 for success, 0 for failure
Args    : string containing parsed seq, value of parsed checksum
