Hi Frederik, Also sorry for the slow response. I was away from the lab all of last week. As Matt said, he and I are working on transitioning Demeter from using Ifeffit by default to using Larch by default. If you were inclined to help us out by installing Larch and testing Demeter with Larch, we would be grateful. I'll say that the benefits will pay off in the long run. Having Larch behind Demeter will enable a lot of new features in Athena and Artemis. For example, I have some ideas for improving Athena's linear combination fitting in ways that cannot be done (or at least not easily) with Ifeffit. It'll be cool. That said, it is quite possible that the HEAD of the git repository could have problems. I haven't properly documented this yet, but it is possible to force Demeter to skip the check for a Larch server and fall back to using Ifeffit (which will continue to be available even after we complete the switch to larch). The easiest way to do so is to set a special environment variable. Try starting Athena with this command: DEMETER_FORCE_IFEFFIT=1 && dathena or, more permanently within a bash session export DEMETER_FORCE_IFEFFIT=1 then a normal "dathena" command will fall back on using Ifeffit. This behavior may change with notice, but I will try to keep the documentation at the website up-to-date. B On 11/10/2016 02:02 PM, Frederik Eistrup wrote:
Dear List,
Recently installed Demeter on Ubuntu for a master's lab work at Bessy II (HZBerlin), with help from David Hughe's instructions (https://bruceravel.github.io/demeter/documents/SinglePage/demeter_nonroot.ht...).
When I run Athena ("dathena" in comand line) the interface window appears but command line has output:
//
/$ dathena Trying Larch server: /home/frederik/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/share/ini/larch_server.ini Trying Larch server: larch_server -p 4966 start Can't exec "larch_server": No such file or directory at /home/frederik/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Larch.pm line 66. /
Later, when i try to import a data-file, column selection windows shows up as it should, but after i've chosen numerator and press OK, the whole Athena crashes. Message on terminal (sorry I know its massive...)://

So, where is the problem? Can anyone helo with this?
Made sure larch was installed through sudo apt-get install, but all stays the same.
Thanks for any help!
