Hi Peter. I haven't looked at this since early 2009 and our motive in making this available as a script (instead of within the aroma.affymetrix package) was simply as an FYI and the code is readily available for others to modify for their needs. You will of course understand that underlying packages change all the time.
On a cursory glance from what you have mentioned below, it seems like the script actually works now problem. Each unit appears to be a "probeset", not a "transcript cluster". I know there was a point (looks like early 2009) where Affymetrix made annotation available at the probeset as well as transcript cluster level, whereas when I built this script there was only transcript cluster. Also, you'll notice my post on BioC: https://stat.ethz.ch/pipermail/bioconductor/2009-July/028893.html ... so, 250k probesets seems about right. You'll notice that BioC now makes available annotation at both levels: http://www.bioconductor.org/packages/release/data/annotation/ (hugene10sttranscriptcluster.db, hugene10stprobeset.db) I'm pretty sure that the 'pd.hugene.1.0.st.v1' package includes information about both probesets and transcript clusters, since oligo::rma() can summarize these chips at both levels. So, it may be an easy modification to make to the script to extract this. Also, you haven't told us what you mean by "aroma.affymetrix will not work with it", so I can't offer much there.
