Hi, Have you tried using extractAffyBatch, which is documented here: http://aroma-project.org/howtos/extractAffyBatch ? As far as I understand you will need the Bioconductor annotation package corresponding to your chip type to be installed, ie
source("http://www.bioconductor.org/biocLite.R") biocLite("hgu133plus2cdf") This is discussed in this thread: http://groups.google.com/group/aroma-affymetrix/browse_thread/thread/40e3950e52d73c1f/772e387a3163db56 Pierre On Tue, Aug 9, 2011 at 4:34 AM, hsingjun cheung <hsingjun.ch...@gmail.com> wrote: > Hi Pierre: > > Thanks.
