NAME

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

SYNOPSIS

 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
  $tool->run();

 # alternatively you can say
 $tool->seq($seq->primary_seq)->run;

 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
     $seq->add_SeqFeature($feat);

}

DESCRIPTION

This class is 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. Optionally you can select the search strincency as well. At present searches for specific phosphorylation sites isn't supported, all predicted sites are returned.

See http://www.scansite.mit.edu/.

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::WebAgent.

APPENDIX

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

result

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

This implementation returns differently processed data depending on argument:

undef

Returns the raw ASCII data stream but without HTML tags

'Bio::SeqFeatureI'

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

'parsed'

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.

stringency

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.

protein_id

 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
				object.
