       Bio::Tools::Run::Alignment::Proda - Object for the calculation of sets of multiple
       sequence alignments from a set of unaligned sequences or alignments using the Proda


         # Build a Proda alignment factory
         $factory = Bio::Tools::Run::Alignment::Proda->new(@params);

         # Pass the factory a list of sequences to be aligned.
         $inputfilename = 't/cysprot.fa';
         # @alns is an array of SimpleAlign objects.
         @alns = $factory->align($inputfilename);

         # or where @seq_array is an array of Bio::Seq objects
         $seq_array_ref = \@seq_array;
         @alns = $factory->align($seq_array_ref);

         # Or one can pass the factory a pair of (sub)alignments
         #to be aligned against each other, e.g.:

         #There are various additional options and input formats available.
         #See the DESCRIPTION section that follows for additional details.

         $factory = Bio::Tools::Run::Alignment::Proda->new();
         @alns = $factory->align($seq_array_ref);


       You can get it and see information about it at this URL

       This program will return one or more local alignments for the different repeated or
       rearranged regions in the sequences. If a sequences contains more than one of those
       patterns, it will be present more than once in the alignment. The difference will be in
       that the id contain the start and end, like myseqid(123-456) and myseqid(567-890), instead
       of simply myseqid as in the original input file. This is true for all the output ids, even
       if they are present only once.

   Helping the module find your executable
       You will need to enable Proda to find the proda program. This can be done in (at least)
       three ways:

         1. Make sure the proda executable is in your path (i.e.
            'which proda' returns a valid program
         2. define an environmental variable PRODADIR which points to a
            directory containing the 'proda' app:
          In bash
               export PRODADIR=/home/progs/proda   or
          In csh/tcsh
               setenv PRODADIR /home/progs/proda

         3. include a definition of an environmental variable PRODADIR
             in every script that will
            BEGIN {$ENV{PRODADIR} = '/home/progs/proda'; }
            use Bio::Tools::Run::Alignment::Proda;


   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.
                  - General discussion  - About the mailing lists

       Please direct usage questions or support issues to the mailing list:

       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.
