[BioC] About Illumina annotation packages lumixxxAll.db

Hi Bob,

The lumiMouseAll.db (or lumiHumanAll.db and lumiRatAll.db) only includes the
annotation information of the probe. It does not include the Illumina ID and
nuID mapping information. The reason is that the recent versions of
BeadStudio always output the probe sequence information together with the
data. So the lumiR can automatically convert  the probe sequences as nuIDs
without needing any libraries.

For your case, because your data is in old version (v1.1), it may not
include the probe sequence in the file. So you need to map the Illumina ID
to nuID first by using package lumiMouseV1 like this:

 x.lumi <- lumiR(fileName,lib='lumiMouseV1')

Later on, if you want to retrieve the annotation information, you can
directly use lumiMouseAll.db, which is in the same format as other
Bioconductor annotation .db packages.

We are also trying to set up an online service to mapping different Illumina
IDs to nuIDs and then retrieve annotation information.
Tell me if you have other questions.
