Dear Bioconductor I am looking for a cdf file for the Rat Gene 1.0 ST Array. There is none available on the Affymetrix website and none on the Bioconductor website. Can you help me? Regards Jan Shaw CSIRO [[alternative HTML version deleted]]

Hi Jan. There is actually an "unsupported" version of the CDF file available from Affy at: http://www.affymetrix.com/support/technical/libraryfilesmain.affx AFAIK, Bioconductor does not provide CDF environments for these chips. One option is to build the environments yourself, e.g. the oligo/ pdInfoBuilder route: http://article.gmane.org/gmane.science.biology.informatics.conductor/1 8963/ Another option is to use the aroma.affymetrix R package: http://groups.google.com/group/aroma-affymetrix/ ... within that, there is a CDF file available from: http://groups.google.com/group/aroma-affymetrix/web/ragene-1-0-st-v1 ... and yet another R package you could try is 'xps': http://article.gmane.org/gmane.science.biology.informatics.conductor/1 7839/ Cheers, Mark On 11/08/2008, at 1:58 PM, <jan.shaw at="" csiro.au=""> <jan.shaw at="" csiro.au=""> wrote: > Dear Bioconductor > > I am looking for a cdf file for the Rat Gene 1.0 ST Array.
