Bio::SeqIO::gcg - GCG 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 GCG flat file databases.

Reporting Bugs
Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via email or the web: bioperl-bugs@bio.perl.org http://bio.perl.org/bioperl-bugs/ Email: birney@ebi.ac.uk lstein@cshl.org 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 fromatted $seq object into the stream Returns : 1 for success and 0 for error Args : Bio::Seq object, sequence string

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