Hi Truls, actually, I don't know why this happened. I had made some modifications to the acceptance generator last week, only for run03, by adding MRST0 detector (via an extra option, since I have been testing it still, so I have not committed it to the software). I could generate maps with it and got quite satisfactory results for the MRS analysis (only for setting 90B1050, by run8505) last week, but I couldn't do it for the other settings yesterday when I did re-analyze the new dst. (and I found I could not do it for the setting 90B1050 which I could before!) It happened, and is really very wired, so asked Ionut to do the same with his acceptance generator - we've got the same error msg. Maybe you have some clue? May it only be related to d+Au runs?
