Thanks for your reply.
Here is one more question.
After clicking the site above (second address you mentioned)
http://www.affymetrix.com/Auth/analysis/downloads/na33/genotyping/OncoScan.na33.r1.annot.csv.zip
the only I can see is the affymetrix main pages and I didn't know where I should go to find annotation file. (of course , I am logged in)
Could you check one more time for me please?
