I'm a beginner just starting with Bioconductor, and I'm having problems: I have some old data from the Atgenome1 (8k) array that I'd like to run through gcrma. I've installed the cdf and probe packages from the Metadata page, but this have different names ('agcdf' and 'atgenome1probe', respectively). If I attempt to run gcrma on my CEL data I'm told that I need 'agprobe' installed. I could try to make the probe package myself but I can't find the appropriate probe sequence file on the Affymetrix website. Any ideas appreciated.
