Dear Biodonductor group,

I have a question relevant to gene expression dataset. Usually, we will have
probes, while a probe set will corresponding to one gene. What should we do
about this?

Do we use probes as our targets or derive only one value from the probe set
corresponding to one gene?

Do you know which R package will do this job? Thanks very much for your
help.

Have a wonderful weekend!

best,
Xiaowei
