Hi,
I've used a number of "annotation.db" packages related to manufactured chip
(like Affymetrix or Agilent for example) of Custom arrays (like LAPOINTE
...) and they were perfect never had a problem.

I prefer to use the .db packages (example
hgug4112a.db<http://bioconductor.org/packages/2.1/data/annotation/html/hgug4112a.db.html>,
LAPOINTE.db, hgu133a2.db<http://bioconductor.org/packages/2.1/data/annotation/html/hgu133a2.db.html>etc...)
because I can transform the package in a MySQL database. Than I can
add some tables, or with an R script I can easily make queries in the
desired database.

Anyway, now I need to use the pedbarrayv9.db (and v10); They are FHCRC Human
Prostate PEDB cDNA Array.

I found out that the probe_id in the database  look like F:206190...
F:206194... etc.

I have some data from GEO and they use PEDB Spot IDs. They look like
P:6860...  P:6868.. etc.

So I can't do any search in the database, and also I can't find information
about such IDs.

Does anybody know something about those IDs and if I can convert F:* in P:**
?

Thank you very much.

Best regards

Francesco
