Dear mailinglist,

I am new to bioconductor, and I have a simple task to performs, so I would
like to ask for yours assistance. I have to analyze an old gene expression
experiment, performed on 5 microarray chip: mu11kA mu11kB, mgu74B, mgu74C2,
and an old GEM platforms for with I have accession number as univocal IDs. I
need to check for some GO terms previously defined by my previously; in
particular I have to retrive all the member.s of the terms in mus musculus,
and then check for intersection with differentially regulated genes.

So in contrast to the typical procedure, I am not looking for enriched
categories, but for some specific terms, regardless of their enrichments (at
least in the beginning). I looked in manual and Workshop, but I can't make
it up.
I tried

> tmp=as.list(GOALLENTREZ)
> match(tmp, my_entrez, nomatch=0)

but I didn't find matches. Actually i think this is because GOALLENTREZ
provides entrez from different species. furthermore HyperG function in
GOstats requires the definition of a chip, but in my case it is a little bit
more complicated.


which strategy would you suggest?
