[BioC] iterative gcrma on 92 slides?

[Dick Beyer]

I would like to do gcrma on 92 chips, type mgu74av2.  I know I won't be able to if I just send all 92 to gcrma.  

I was wondering if there were a way to iteratively get to the answer.  Would it be useful to do gcrma in doable batches, say 20 or so, then do quantile normalization on all 92?

Or can I do justRMA on the 92, then somehow process the exprSet to achieve a gcrma result?

I am willing to try different approaches, but I am hoping for some advice on which ways might be best.

Thanks very much,
Dick
