with R 2.15, this command was not working for me with mouse exon array. I succeeded in loading and normalizing the data with the following lines of code. I though it may be usefull to know for someone who would experience the same problem :

phenoData contains the same things as the covdesc file described in the article. Loadinf and PreProcessing are done in one single step (replacing lines 2, 3 and 4).
