Hi, I was wondering if anyone knew how (if possible) I could normalise moe430a and moe430av2 chips together. >From the information supplied by affymetrix .....The arrays contain identical probes sets but they are in a different format.... 430A having 18um features and 430A 2.0 having 11um features. Because the features and array area are smaller in v2, the CDFs are different. Any ideas would be greatly appreciated. Regards Marg
