We are trying to use Affymetrix U133AAofAv2 chips, which information is provided at the web https://www.affymetrix.com/support/developer/tools/hta_tools.affx. But we could not find a CDF package for this chip on http://www.bioconductor.org/data/metaData.html. We want to get it and to input it to affylmGUI under MS-Windows. It will be grateful if you could help us on this issue. Thank you. Masato
