Dear ZRL?

You can have a look at:

For example, package xps allows you to do RMA for exon arrays and do 
summarization on the probeset level or on the transcript (gene) level.

P.S.: There is no official version of "HuEx-1_0-st-v2.cdf" only an 
unsupported version since for exon arrays Affymetrix uses the 
"HuEx-1_0-st-v2.r2.pgf" file.

Best regards

V.i.e.n.n.a           A.u.s.t.r.i.a
e.m.a.i.l:        cstrato at aon.at
