[BioC] How to get Raw Affy Chip Intensity after RMA

[Saurin Jani]

Hi,

This might be very simple question, and I would like
to confirm that what I am doing is wrong or right..!!
here, what I do..: I have 6 CEL files, 3 Control and 3
Experimental.

> myRMA<- rma(abatch);
> MatrixRMA <- exprs(myRMA); 

> Group1_Raw_Mean_Intensity <-
as.matrix(rowMeans(2^MatrixRMA[,1:3]));

> Group2_Raw_Mean_Intensity <-
as.matrix(rowMeans(2^MatrixRMA[,4:6]));

Any help will help...!!

Thank you,
Saurin
