Hi
Yes, ideally all dr?.e* files are empty as these contain any error messages in case some sub-task does not correctly. These being empty simply measn that all ran fine. Similarly, the dr?.o* files are created to receive the (non-error) outputs from the tasks. drA-drC will not produce any text outputs, so these files should be empty, too. drD.o* contains the command line outputs from randomise and should look like what you describe. All fine it seems
