[BioC] how to do cross species annotation?

[michael watson (IAH-C)]

I'd use biomaRt

3 queries:

Affy human to human ensembl id
Human ensemble id to mouse ensembl id
Mouse ensembl id to Affy mouse

Then join them using the merge() function

Dear list,

If I have a set of affy probes (probe sets) from Human platform, and I
want identify the corresponding probes (probe sets) in mouse platform,
vice versa.

Is there a tool/package to do that? Thanks.

Qiudao
