First, make sure to read http://aroma-project.org/setup/ so you understand where CDF file goes. The download the binary CDF that I've created: http://aroma-project.org/chipTypes/ATH1-121501 because the one that Affymetrix provides is in an ASCII format which is very slow to work with. The retry with: cdf <- AffymetrixCdfFile$byChipType("ATH1") You should not use an 'r3' tags, because the CDF has no such tag part of its filename. To understand what the term "tag" means, see http://aroma-project.org/definitions/. I strongly recommend that you make sure that you understand how filenames, directory names and fullname, name, tags are related - it really helps. /Henrik > > > -- > -- > When reporting problems on aroma.affymetrix, make sure 1) to run the latest > version of the package, 2) to report the output of sessionInfo() and > traceback(), and 3) to post a complete code example. > > > You received this message because you are subscribed to the Google Groups > "aroma.affymetrix" group with website http://www.aroma-project.org/. > To post to this group, send email to aroma-affymetrix@googlegroups.com > To unsubscribe and other options, go to http://www.aroma-project.org/forum/ > > --- > You received this message because you are subscribed to the Google Groups > "aroma.affymetrix" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to aroma-affymetrix+unsubscr...@googlegroups.com. > For more options, visit https://groups.google.com/groups/opt_out. -- -- When reporting problems on aroma.affymetrix, make sure 1) to run the latest version of the package, 2) to report the output of sessionInfo() and traceback(), and 3) to post a complete code example.
