Dear BioC people,
I'm trying to integrate the results of two experiments, one involving
moe430 A and B chips, the other moe430_2 chips.
Hence I thought about combining AffyBatches from moe430 A and B into
one, to get moe430_2 "equivalents".
This is relatively easy to do after processing (i.e. at the probeset
level), but the trick is that I would really like to do this at the
probe level (because I would like to normalize the combined chips
together with moe430_2 chips - not sure if this make sense by the way).
1) Does anyone know if there is a function written somewhere that could
help?
2) Or, would it be possible to create a moe430_2 AffyBatch object from
scratch?
(I could probably read an existing chip and replace the PMs and MMs but
that's not very elegant, is it?)
3) Or, if nothing else, would there be a function to do quantile
normalization at the probeset level?
Thanks for any ideas...
