NAME

Bio::Matrix::PSM::InstanceSiteI - InstanceSite interface, holds an instance of a PSM

CONTENTS

SYNOPSIS



  use Bio::Matrix::PSM::InstanceSite;
  #Y ou can get an InstanceSite object either from a file:
  my ($instances,$matrix)=$SomePSMFile->parse_next;
  #or from memory
  my %params=(seq       => TATAAT,
              id        => "TATAbox1",
              accession => ENSG00000122304,
              mid       => TB1,
              desc      => TATA box, experimentally verified in PRM1 gene,
              relpos    => -35);



DESCRIPTION

Abstract interface to PSM site occurrence (PSM sequence match). InstanceSite objects may be used to describe a PSM (See Bio::Matrix::PSM::SiteMatrix) sequence matches. The usual characteristic of such a match is sequence coordinates, score, sequence and sequence (gene) identifier- accession number or other id. This object inherits from Bio::LocatableSeq (which defines the real sequence) and might hold a SiteMatrix object, used to detect the CRE (cis-regulatory element), or created from this CRE. While the documentation states that the motif id and gene id (accession) combination should be unique, this is not entirely true- there might be more than one occurrence of the same cis-regulatory element in the upstream region of the same gene. Therefore relpos would be the third element to create a really unique combination.

    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.
