[BioC] Identifying the genome sequence of an affy probe

[Schragi Schwartz]

Hi,

I'm looking for a package that will give me the sequence of affy
probes in the Human U133A 2.0 package. In other words, I have a list
of affy ids (e.g. 237488_s_at, etc.) and I would like to know the
sequences of original 25 mers this probe corresponds to.

Thanks,
Schragi
