[BioC] affy package pm ids and position on mRNA

[Keith Vass]

Hi all

I have used affy to get perfect-match probe data for a number of affy
HG-U133a chips and I get the probes as follows 210298_x_at1, 210298_x_at2
etc

How do I find out what the mapping is to the oligodata that Affymetrix
give for their probes as I want to know the position the oligos bind to in
the sequence as this is a gene with an alt-splicing site?

Look forward to your reply.

Keith
