HuGene-1_0-st-v1 .r4 .txt/csv

Hi,
We have been trying to analyze HuGene-1_0-st-v1.r4, and we have some qüestions.
I have read that .r3 was the last .CDF, and now is impossible to download the .r4 from Affymetrix. They give you .r4.all.ps ; .r4.bgp; .r4.clf; .r4.mps; .r4.pgf; .r4.qcc. I think it's possible to open .CEL with GCOS but, is it possible with j-express? Maybe in a future?

Moreover, fortunately we have .txt with the RMA performed. But we have some problems trying to perform Gene ontology mapping or GSEA. I think the problem is that .CSV file from Affymetrix don't have a column with ONLY geneID or other ID, they give for example swissprot and more information after de ID. I have followed your manual and downloaded daily .obo and daily GO archives, but with or without synonims (col 3 or 11) it is not readable. I'd like to know if I'm doing something wrong or if there is some other .TXT with a compatible annotation.

Thanks for your help.
