You need to take the log2 of the residuals. CEL files store only
positive numbers.
This question has been answered many times. For starters, have a look

HI,
I found the FIRMA scores are all >0, so what do you mean the
positive or negative? and i am not very understand this sentence "it
seems logical to find FIRMA scores that are different b/w your 2+
groups". That if there are several samples in each group, how to deal
with it?
Thanks,
Jiang
