NAME
Bio::SeqIO::gcg - GCG sequence input/output stream
SYNOPSIS
Do not use this module directly. Use it via the Bio::SeqIO class.
DESCRIPTION
This object can transform Bio::Seq objects to and from GCG flat file databases.

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 objectGCG_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 occured.
:
Returns : 1 for success, 0 for failure
Args : string containing parsed seq, value of parsed cheksum
