[BioC] normalization

[gjam at daimi.au.dk]

Hi,
I want to normalize a set of data from different microarrays, and for each of
the experiments (microarray) I only have the control values at 0h. This means
that I don't have any  duplicates.
I've already used the rma method to preprocess that data, and I've put the mean
at 0 and the variance at 1. Do you have an idea on what I could do next to
furthur normalize my data so that I can compare them?

Thanks a lot,
Jamila
