I have a bunch of cel files profiled on U133A, U133A2 and U133plus2.
Obviously, in order to combine them, I'll only focus on the common probes
shared by the 3 different platforms. However, I am not sure what is the
correct way of RMA normalizing them. Should cel files from the same platform
RMA normalized separately, or they can be RMA normalized by only focusing on
the common probe sets?

Thanks,

-Jack
