Hi,

I am working on a project where i have to link the probes of different
microarray platforms (Affymetrix, Agilent, ABI Gene, Illumina). I would like
to know or this is possible with Bioconductor\R.
I can get the annotation files of the manufacturers where for each probe the
Genbank id is specified. With the AnnBuilder package the genbank id's can be
linked to the Unigene id's.
When i create a package for each platform, i thougth it would be possible to
get the overlapping probes by selecting the UniGene identifiers that are
pressent in each platforms. Is this possible with the Annotate package? I
saw things like the get and multiget functions, but can these functions also
be used with multiple packages?
The result has then to be visualised in a Venn Diagram (i saw examples in a
few articles) and a spreadsheet listing all overlapping probes.
I am relatively new to R/Bioconductor, so i would like to know the above is
possible with the AnnBuilder and Annotate packages. Maybe someone can give
me some hints to get started?

Thanks
