Hello Benilton, At first I tried 20 .cel files, but reduced it to 4. In both cases R dies after ~0.5 sec after the command is issued. These are Affyemtrix 500k arrays (in reality they are 250k since the same sample is digested by two diferent enzymes, STY and NSP on two different arrays, making one 500k virtual array out of two physical 250k arrays) NB these are official HapMap 500k arrays downloaded from http://hapmap.jst.go.jp/downloads/raw_data/affy500k/ hope this is helpful morten > Hi Morten, > > thanks for your feedback.
