[BioC] Affy probeset annotations

[Nianhua Li]

Dear Karen,

rat2302 is generated by first mapping probeset IDs to Entrez Gene IDs and then
retrieving annotations of those Entrez Gene IDs from public databases. The
vigentte of AnnBuilder ("How to use AnnBuilder") lists the URLs of those public
databases. Also, this post explains a bit about the probeset to Entrez Gene
mapping process:

Similar questions have been asked and answered many times. Maybe you could dig
more in the mailinglist...

HTH
