\title{get the viewpoint of 3C-seq data}

\description{
  The viewpoint is the region of interest, which can be a promoter region of an interested gene, 
  an enhancer, and a transcrition factor binding region. The genomic region, which show the highest number of reads per
  restriction fragment, represents the viewpoint.
   
}

\usage{
getViewpoint(object)
}


\arguments{

	\item{object}{
		r3Cseq object, the object is the container of interaction regions produced by \code{\link{getInteractions}} function.
	}
}

\value{
   The viewpoint shows in the IRanges
}
