49 =head1 DESCRIPTION
|
|
50
|
|
51 This class describes a local mutation event using minimalistic
|
|
52 description. It is not necessary to know anything about the original
|
|
53 sequence. You need to give the changed sequence, the position of the
|
|
54 mutation in the (unidentified) reference sequence, and the length of
|
|
55 the affected subsequence in the reference sequence. If the original
|
|
56 allele sequence is given, the objects applying the mutation into the
|
|
57 reference sequence (e.g. L<Bio::LiveSeq::Mutator>) might check for its
|
|
58 validity.
