I attempted to use the script posted on the site to convert the
pd.hugene.1.0.st.v1 package to a CDF file but it appears not to be
working. The resulting cdf file has too many units and
aroma.affymetrix will not work with it beyond naming the CDF. Are you
aware of any issues?

  PdInfo2Cdf("pd.hugene.1.0.st.v1", "A1_Affy.CEL", overwrite=TRUE)

I renamed the resulting binary cdf file and moved it to the appropriate
aroma.affymetrix directory.

    chipType <- "HuGene-1_0-st-v1"
    cdf <- AffymetrixCdfFile$byChipType(chipType, tags="r4")

> print(cdf)

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.
