Hi guys, I have affy U133A array probe IDs that I need to map to the meta- probeset ids from the GeneChip Human Exon 1.0ST array. They both target transcripts so it should be possible to some extent (thhough annotations change so I wouldn't expect it to work for every probe). Any pointers on a quick way to do it? -Paul. -- Paul Geeleher School of Mathematics, Statistics and Applied Mathematics National University of Ireland Galway Ireland [[alternative HTML version deleted]]

Dear Paul, Have a look at: http://www.affymetrix.com/products_services/arrays/specific/exon.affx# 1_4 especially at "HG-U133 Plus to Human Exon 1.0 ST, Best Match (zip, 899 KB)" Best regards Christian _._._._._._._._._._._._._._._._._._ C.h.r.i.s.t.i.a.n S.t.r.a.t.o.w.a V.i.e.n.n.a A.u.s.t.r.i.a e.m.a.i.l: cstrato at aon.at _._._._._._._._._._._._._._._._._._ Paul Geeleher wrote: > Hi guys, > > I have affy U133A array probe IDs that I need to map to the meta- probeset > ids from the GeneChip Human Exon 1.0ST array.
