=head1 NAME
Bio::Tools::Run::Pseudowise - Object for prediting pseudogenes in a
given sequence given a protein and a cdna sequence
=head1 SYNOPSIS
# Build a pseudowise alignment factory
my $factory = Bio::Tools::Run::Pseudowise->new();
# Pass the factory 3 Bio:SeqI objects (in the order of query
# peptide and cdna and target_genomic)
# @genes is an array of GenericSeqFeature objects
my @genes = $factory->run($seq1, $seq2, $seq3);
=head1 DESCRIPTION
Pseudowise is a pseudogene predition program developed by Ewan Birney
http://www.sanger.ac.uk/software/wise2.
=head1 FEEDBACK
=head2 Mailing Lists
User feedback is an integral part of the evolution of this and other
Bioperl modules. Send your comments and suggestions preferably to one
of the Bioperl mailing lists. Your participation is much appreciated.

=head2 Support
Please direct usage questions or support issues to the mailing list:
I<bioperl-l@bioperl.org>
rather than to the module maintainer directly. Many experienced and
reponsive experts will be able look at the problem and quickly
address it. Please include a thorough description of the problem
with code and data examples if at all possible.
=head2 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 the
