\keyword{manip}{imageScreen}
\begin{Description}\relax
Experiment-wide quality control plot of a scored cellHTS object.
\end{Description}
\begin{Usage}
\begin{verbatim}
imageScreen(x, ar=3/5, zrange)
\end{verbatim}
\end{Usage}
\begin{Arguments}
\begin{ldescription}
\item[\code{x}] a cellHTS object that has already been scored (i.e. containg the slot \code{score}).
\item[\code{ar}] the desired aspect ration for the image plot (i.e. number of columns per number of rows)
\item[\code{zrange}] the range of values to be mapped into the color
scale. If missing, zrange will be set to the range of \code{x\$score}.
\end{ldescription}
\end{Arguments}
\begin{Details}\relax
This function creates an image plot that gives an overview of the whole set of score values 
from the cellHTS object \code{x}.
