[BioC] onvert an already existing CDF environment into a CDF file or CDF package

[shirley zhang]

Dear List,

I tried 'makecdfenv' to make a  CDF package starting from an
Affy-provided CDF file. Can anybody tell me how to convert an already
existing CDF environment into a CDF
file or CDF package in order to be used in aroma.affymetrix package?

I am very very appreciated If anybody can give a specific example for
working with Affymetrix Exon Array.

Thanks,
Shirley
