Hi!
I found online this discussion because I'm looking for the CDF file for
Oncoscan CNV array.
I'm new to R and data analysis but everything that I've found so far to
analyze CEL files requires that CDF file.
Have you managed to find a solution during these past years?
Thank you in advance.

When reporting problems on aroma.affymetrix, make sure 1) to run the latest
version of the package, 2) to report the output of sessionInfo() and
traceback(), and 3) to post a complete code example.
