[BioC] Analysing multiple-platform gene expression data

[Paul Geeleher]

Hey might be worth doing a search on pubmed or google to see if there
are published studies that have a similar setup and just do what
they've done.

Possibilities might be to use brainarray custom CDFs to reduce both
platforms to entrez gene ids, subset on ids common to both platforms
then use something like rankproduct (which uses gene ranks rather than
expression level) to compare between between the two types of arrays.

Paul.
