[BioC] Mapping Affymetrix annotations with Bioconductor annotations

[Joao Sollari Lopes]

Hi,

I am trying to compare the annotations provided by Affymetrix with the 
ones provided by Bioconductor for

Zebrafish Gene 1.1 ST Array Strip

I have compared the files

zebgene11stdrentrezg.db_17.1.0.tar.gz 
(http://brainarray.mbni.med.umich.edu/Brainarray/Database/CustomCDF/17.1.0/entrezg.download/zebgene11stdrentrezg.db_17.1.0.tar.gz)

ZebGene-1_1-st-v1.na33.3.zv9.transcript.csv.zip 
(http://www.affymetrix.com/Auth/analysis/downloads/na33/wtgene-33_3/ZebGene-1_1-st-v1.na33.3.zv9.transcript.csv.zip) 


The trouble is that the first identifies the Units as "100000002_at", 
"100000006_at", ...,  "84703_at" and the second as "12943944", 
"12943954", ..., "13276104". Is there an easy way to know which 
correspond to which?

Thanks in advance,
