NAME

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

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.
