I often make use of Artemis' option of plotting the sum of paths (with current parameters) to double check the starting values for a full fit. Under the sum of paths (no fit) option, there are two sub-options, one "use all paths" and "use only selected paths". I believe that regardless of which option is chosen only selected paths are summed. I noticed this as I had a very unique path that really stuck out and using the sum all paths option I could turn on and off its appearance by selecting or de-selecting this path. This was regardless of the fact that I had selected the "use all paths" sub-option. As the behavior one usually wants is to sum only selected paths, this is not a very serious problem, however, it is potentially misleading and ?probably easy to fix. This is with the latest version of artemis rc2. Paul
