Hi Dick,

The affy annotation is correct. I'm working on an alternative Bioconductor
package (biomaRt) that can be used for annotation and retrieves the
annotation directly from Ensembl (http://www.ensembl.org). You can find
the biomaRt package in the developmental packages if you want to give it a
This is what it returned for your query:

I ran into an oddity that I thought others working with hgu133plus2 chips
might want to know.

hgu133plus2SYMBOL is missing an entry for 211506_s_at.

[1] ""

But the netaffx website shows the Gene Symbol for 211506_s_at as IL8.
