Hi everyone,

As a matter of fact, we are aware that in affymetrix U133plus2.0 Chip, probesets are targeted to different regions of sequence. Some probesets locate at the coding sequence regions, and others locate at untranslated regions. My question is that is there any function or package existed to distinguish probesets according to their location on the sequences?

Any suggestions and comments are welcome and highly appreciated! Thank you!

Best wishes
Qinghua
