Send your comments and suggestions preferably to the Bioperl mailing lists Your participation is much appreciated. bioperl-l@bioperl.org - General discussion http://bio.perl.org/MailList.html - About the mailing lists =head2 Reporting Bugs report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution.

Internal methods are usually preceded with a _ =cut # Let the code begin... package Bio::Variation::SNP; my $VERSION=1.0; use strict; use vars qw($VERSION @ISA $AUTOLOAD); use Bio::Root::Root; use Bio::Variation::SeqDiff; use Bio::Variation::Allele; @ISA = qw( Bio::Variation::SeqDiff Bio::Variation::Allele); =head2 get/set-able methods Usage : $is = $snp->method() Function: for getting/setting attributes Returns : a value. probably a scalar.
