Hi Dick. (I've copied the aroma.affymetrix list in case others have the same question).
I remember doing an update *late* last year (don't remember exactly when) and recreating the CDFs --- the contents were identical to previous ones. That is, the Affymetrix annotation (at least how probesets are put into transcript clusters) doesn't change that much. I haven't checked recently -- do you know if Affy has made some major changes? If so, I'm happy to recreate them. But, just because they are dated July 2008, doesn't mean they have old information. However, if you use the Ensembl builds (for Exon 1.0ST), these change more regularly. The last one I built was Ensembl 50 and I see Ensembl is now at v54. In general, building CDFs for Exon arrays is described at: http://groups.google.com/group/aroma-affymetrix/web/creating-cdf-files-from-scratch Cheers, Mark On 12/06/2009, at 9:23 AM, dbe...@u.washington.edu wrote: > Hi Mark, > > I was wondering if there was any planned updates to the Mouse Exon 1.0 > ST cdf files?
