Dear Bruce and other people in the list, I have just installed Demeter from the git on Ubuntu 12.04 using instructions given by Dave Hughes ( https://gist.github.com/waveform80/3959252). Everything went fine during installation but then I tried to start Athena using *dathena* command from the terminal and I got this message: Demeter says: Uh oh! You have requested using Larch, but there is no Larch server running! Then I installed Larch (with some problems during installation, but that is different story) and again tried starting Athena with the same result. When I tried starting Larch in a server mode with *larch -r* command it didn't offer a possibility to start Athena in the same terminal window. Then I opened a new tab in the terminal and just typed *dathena* and the GUI appeared. Now, I have two questions: 1. Do I have to start Larch server every time like this before using Athena or is there some other solution for this? 2. I tried Artemis without Larch server running and didn't get the error message. Is Artemis independent from Larch or are there some problems that might occur later? -- Best wishes, Dr Ivan Stijepović Department of Materials Engineering Faculty of Technology University of Novi Sad Bul. cara Lazara 1 21000 Novi Sad Serbia tel: +381 21 485 3750 fax: +381 21 450 413 e-mail: ivan.stijepovic@gmail.com
