Dear All, I'm trying to read a CHP file produced by Affymetrix Genotyping Console software. It seems that readChp can only read the summary information from the file, is that correct, or am I doing something wrong? Is there another package or piece of software that can read these files? Thanks, Gabor -- Gabor Csardi <Gabor.Csardi at unil.ch> UNIL DGM
