\begin{Description}\relax
This class represents pre-normalization intensity data for a batch of cDNA microarrays. A \emph{batch of arrays} consists of a collection of arrays with the same layout  (\code{"\Link{marrayLayout}"}). The class contains slots for the green (Cy3) and red (Cy5) foreground and background intensities, the layout of the arrays, and descriptions of the target samples hybridized to the arrays and probe sequences spotted onto the arrays.
\end{Description}
\begin{Section}{Objects from the Class}
Objects can be created by calls of the form 
\code{  new('marrayRaw',}\\
\code{    maRf      = ...., \# Object of class matrix}\\
\code{    maGf      = ...., \# Object of class matrix}\\
\code{    maRb      = ...., \# Object of class matrix}\\
\code{    maGb      = ...., \# Object of class matrix}\\

\code{    maLayout  = ...., \# Object of class marrayLayout}\\
\code{    maGnames  = ...., \# Object of class marrayInfo}\\
\code{    maTargets = ...., \# Object of class marrayInfo}\\
\code{    maNotes   = ...., \# Object of class character}\\
