NAME

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 program.

CONTENTS

SYNOPSIS



  # 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);



DESCRIPTION

You can get it and see information about it at this URL http://proda.stanford.edu

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;



FEEDBACK

    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.

    Support

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

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.

 Title   : new
 Usage   : my $proda = Bio::Tools::Run::Alignment::Proda->new();
 Function: Constructor
 Returns : Bio::Tools::Run::Alignment::Proda
 Args    : -outfile_name => $outname



    error_string



 Title   : error_string
 Usage   : $obj->error_string($newval)
 Function: Where the output from the last analysus run is stored.
 Returns : value of error_string
 Args    : newvalue (optional)



    version



 Title   : version
 Usage   : exit if $prog->version() < 1.8
 Function: Determine the version number of the program
 Example :
 Returns : float or undef
 Args    : none



    run



 Title   : run
 Usage   : my $output = $application->run(\@seqs);
 Function: Generic run of an application
 Returns : Bio::SimpleAlign object
 Args    : Arrayref of Bio::PrimarySeqI objects or
           a filename to run on



    align



 Title   : align
 Usage   :
        $inputfilename = t/data/cysprot.fa;
        $aln = $factory->align($inputfilename);
or
        $seq_array_ref = \@seq_array;
        # @seq_array is array of Seq objs
        $aln = $factory->align($seq_array_ref);
 Function: Perform a multiple sequence alignment
 Returns : Reference to a SimpleAlign object containing the
           sequence alignment.
 Args    : Name of a file containing a set of unaligned fasta sequences
           or else an array of references to Bio::Seq objects.

 Throws an exception if argument is not either a string (eg a
 filename) or a reference to an array of Bio::Seq objects.  If
 argument is string, throws exception if file corresponding to string
 name can not be found. If argument is Bio::Seq array, throws
 exception if less than two sequence objects are in array.
