[BioC] How to add annotation information?

Hi Marc,

I am using Affymetrix Mouse Gene 1.0-ST Array. I should ask the person
who did the experiment which version the array is, right? Base on the
version, I should use either mogene10stprobeset.db or
mogene10sttranscriptcluster.db, right?

I have read the document, but I am still not sure what command I
should use to convert the id to the annotation. Suppose I should use
mogene10stprobeset.db, would you please let me know what commands I
should use?

Regards,
Peng
