       Bio::Tools::Run::MCS - Wrapper for MCS


         use Bio::Tools::Run::MCS;

         # Make a MCS factory
         $factory = Bio::Tools::Run::MCS->new();

         # Run MCS on an alignment
         my @results = $factory->run($alignfilename);

         # or with alignment object
         @results = $factory->run($bio_simplalign);

         # look at the results

           my ($pvalue) = $feat->get_tag_values('pvalue');

       This is a wrapper for running the MCS (binCons) scripts by Elliott H Margulies.  You can
       get details here: MCS is used for the
       prediciton of transcription factor binding sites and other regions of the genome conserved
       amongst different species.

       Note that this wrapper assumes you already have alignments, so only uses MCS for the
       latter stages (the stages involving, and

       You can try supplying normal MCS command-line arguments to new(), eg.

         $factory->new(-percentile => 95)

       or calling arg-named methods (excluding the initial hyphens, eg.


        to set the --percentile arg).

       You will need to enable this MCS wrapper to find the MCS scripts.  This can be done in (at
       least) three ways:

        1. Make sure the MCS scripts are in your path.
        2. Define an environmental variable MCSDIR which is a
           directory which contains the MCS scripts:
           In bash:

           export MCSDIR=/home/username/mcs/

           In csh/tcsh:

           setenv MCSDIR /home/username/mcs

        3. Include a definition of an environmental variable MCSDIR in
           every script that will use this MCS wrapper module, e.g.:

           BEGIN { $ENV{MCSDIR} = '/home/username/mcs/' }
           use Bio::Tools::Run::MCS;


   Mailing Lists
       User feedback is an integral part of the evolution of this and other Bioperl modules. Send
       your comments and suggestions preferably to the Bioperl mailing list.  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.

       The rest of the documentation details each of the object methods.  Internal methods are
       usually preceded with a _

        Usage   : $factory>program_name()
        Function: holds the program name
        Returns : string
        Args    : None

        Title   : program_dir
        Usage   : $factory->program_dir(@params)
        Function: returns the program directory, obtained from ENV variable.
        Returns : string
        Args    : None

        Title   : new
        Usage   : $factory = Bio::Tools::Run::MCS->new()
        Function: creates a new MCS factory
        Returns : Bio::Tools::Run::MCS
        Args    : Many options understood by MCS can be supplied as key =>
                  value pairs.

                  These options can NOT be used with this wrapper:

        Usage   : $result = $factory->run($align_file_or_object, Bio::Location::Atomic,

        Returns : list of Bio::SeqFeatureI feature objects (with coordinates corrected
                  according to the supplied offset, if any)
        Args    : The first argument represents an alignment, the optional second
                  argument represents the chromosome, stand and end and the optional
                  third argument represents annotation of the exons in the alignment.

                  The alignment can be provided as a multi-fasta format alignment
                  filename, or a Bio::Align::AlignI compliant object (eg. a
