Hi Rui,

Thanks once again for all the help. I need to ask for one more help from you. I have two matrices, with probesets as rows and samples as columns.
The samples in the two matrices are matched (from the same animal but two different tissues). I want to create a correlation matrix of sample by sample using the probeset expression values. Could you please suggest a way to do that?

Thanks,
Som.
