hi every body, I am going to use gcrma normalization for a u133aaofav2 platform (Cmap data). but when I use function gcrma(), the following error appear. "Environment u133aaofav2probe was not found in the Bioconductor repository."
I searched the error but I couldnt find any answer for my problem. there is no package for u133aaofav2 probe annotation. I would be greatfull if some one could help me.
