It is not necessary to know anything about the original +sequence. You need to give the changed sequence, the position of the +mutation in the (unidentified) reference sequence, and the length of +the affected subsequence in the reference sequence. If the original +allele sequence is given, the objects applying the mutation into the +reference sequence (e.g. L<Bio::LiveSeq::Mutator>) might check for its +validity. + +=head1 FEEDBACK + +=head2 Mailing Lists + +User feedback is an integral part of the evolution of this and other +Bioperl modules.
