Hi Sebastien. Interesting observation, I hadn't noticed that. Since the major difference is in the fitting stage, my guess would be that there are just more larger units (although less total units) in the RaGene CDF. This is certainly true for say, the number of probesets with more than 1

Hi folks. Sorry for the delay on replying to this one, I meant to comment on this earlier. There are a lot of questions on the BioC newsgroup lately about custom CDFs and picking probes and so on. To have complete control, you would probably want to be familiar with the exact information

Hi Mathieu. What is your plan for the analysis? What does 'n=4, N=8' mean? Regardless, it seems like you might start with the "coreR1" CDF from: http://groups.google.com/group/aroma-affymetrix/web/raex-1-0-st-v1 ... and you could follow the use-case from (replacing the human exon with rat e
