\title{
Identical signature features selection from cghCall-object.
}
\description{
Given an example, selects features (contiguous to the example) with the same signature (as the example) across samples from an \code{\link{cghCall}}-object.
}
\usage{
getSegFeatures(featureNo, CNdata, verbose=TRUE)
}
\arguments{
  \item{featureNo}{ Row number of example feature. }
  \item{CNdata}{ Object of class \code{\link{cghCall}}. }
  \item{verbose}{ Logical indicator: should intermediate output be printed on the screen? }
}
\value{
Object of class \code{numeric}, containing the row numbers of those contiguous features with the same segmented log2-ratio signatures as \code{featureNo} across samples.
