Harry, Wolfgang and James,

The exon and gene ST arrays do not use, or even have, a CDF file for the 
array, I think a requirement for makecdfenv. These arrays use clf and 
pgf files, hence the need for the oligo set of packages.

You can try changing the name of pd.ragene.1.0.st.v to ragene10stv1cdf 
then reinstalling. This should at least enable you to load the package 
within affylmgui, there may be errors when affylmgui tries to access the 
information in the package and I would be interested in what they are. I 
can then work on updating oligo to add an interface similar to what the 
affylmgui is expecting.
