       Bio::Tools::Analysis::Protein::Scansite - a wrapper around the Scansite server


         use Bio::Tools::Analysis::Protein::Scansite;

         my $seq; # a Bio::PrimarySeqI object

         my $tool = Bio::Tools::Analysis::Protein::Scansite->new
            ( -seq => $seq->primary_seq );

         # run Scansite prediction on a sequence

         # alternatively you can say

         die "Could not get a result" unless $tool->status =~ /^COMPLETED/;

         print $tool->result;     # print raw prediction to STDOUT

         foreach my $feat ( $tool->result('Bio::SeqFeatureI') ) {

             # do something to SeqFeature
             # e.g. print as GFF
             print $feat->gff_string, "\n";
             # or store within the sequence - if it is a Bio::RichSeqI



       This class is a wrapper around the Scansite 2.0 server which produces predictions for
       serine, threonine and tyrosine phosphorylation sites in eukaryotic proteins. At present
       this is a basic wrapper for the "Scan protein by input sequence" functionality, which
       takes a sequence and searches for motifs, with the option to select the search stringency.
       At present, searches for specific phosphorylation sites are not supported; all predicted
       sites are returned.

   Return formats
       The Scansite results can be obtained in several formats:

       1. By calling

            my $res = $tool->result('');

          $res holds a string of the predicted sites in tabular format.

       2. By calling

            my $data_ref = $tool->result('value')

          $data_ref is a reference to an array of hashes. Each element in the array represents a
          predicted phosphorylation site. The hash keys are the names of the data fields,i.e.,

              'motif'      => 'Casn_Kin1'       # name of kinase
              'percentile' => 0.155             # see Scansite docs
              'position'   => 9                 # position in protein
              'protein'    => 'A1'              # protein id
              'score'      => 0.3696            # see Scansite docs
              'sequence'   => 'ASYFDTASYFSADAT' # sequence surrounding site
              'site'       => 'S9'              # phosphorylated residue
              'zscore'     => '-3.110'          # see Scansite docs

       3. By calling

            my @fts = $tool->Result('Bio::SeqFeatureI');

          which returns an array of Bio::SeqFeatureI compliant objects with primary tag value
          'Site' and tag names of 'motif', 'score', 'sequence', 'zscore' as above.

       See <>.

       This inherits Bio::SimpleAnalysisI which hopefully makes it easier to write wrappers on
       various services. This class uses a web resource and therefore inherits from


       Bio::SimpleAnalysisI, Bio::WebAgent


   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.

   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 web:

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

        Name    : result
        Usage   : $job->result (...)
        Returns : a result created by running an analysis
        Args    : none (but an implementation may choose
                  to add arguments for instructions how to process
                  the raw result)

       The method returns a scalar representing a result of an executed job. If the job was
       terminated by an error, the result may contain an error message instead of the real data.

       This implementation returns differently processed data depending on argument:

          Returns the raw ASCII data stream but without HTML tags

          The argument string defined the type of bioperl objects returned in an array.  The
          objects are Bio::SeqFeature::Generic.

          Returns a reference to an array of hashes containing the data of one phosphorylation
          site prediction. Key values are:

          motif, percentile, position, protein, score, site, zscore,  sequence.

        Usage    : $job->stringency(...)
        Returns  : The significance stringency of a prediction
        Args     : None (retrieves value) or 'High', 'Medium' or 'Low'.
        Purpose  : Get/setter of the stringency to be sumitted for analysis.

        Usage    : $job->protein_id(...)
        Returns  : The sequence id of the protein or 'unnamed' if not set.
        Args     : None
        Purpose  : Getter of the seq_id. Returns the display_id of the sequence
