[BioC] error in hugene10sttranscriptcluster

Hi Javier,

The annotation of Affy chips tends to change over time, and this might
be an instance of that. If you check netaffx for this probeset, the
transcript it measures is described as 'multiple', and if you blat the
sequence they built the probeset against, it matches all over the place.
So it may be that in the past they claimed a direct match and now they
don't. 

You could investigate this further by looking at older versions of the
annotation files if you care to know more.

Best,

Jim

Dear list,
I'm trying to get the ENTREZIDs of some Affy_IDs of GeneChip Human Gene 
ST 1.0 Arrays through hugene10sttranscriptcluster package. Depending on 
the R version, the results are different.
For example, in R 2.12.2:
 > mget("8104901",hugene10sttranscriptclusterENTREZID)
$`8104901`
[1] "3575"

But
 >mget("8019631",hugene10sttranscriptclusterENTREZID)
Error en .checkKeys(value, Lkeys(x), x at ifnotfound) :
   value for "8019631" not found

Why this error for Affy_ID 8019631 when R2.12.2 is used?
Thanks,
