\usage{data(exp.arr)}
\format{
  The format is:
 num [1:6384, 1:16] -0.2500  0.0329 -0.2065 -0.2240 -0.8542 ...
 - attr(*, "dimnames")=List of 2
  Each row represents a gene: chr [1:6384] "1" "2" "3" "4" ...
  Each column represents a sample : chr [1:16] "X1" "X2" "X3" "X4" ...
}
\details{
	The data is normalized.
