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.html).

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...):

Attribute (bkg_pre1) does not pass the type constraint because: Validation failed for 'LaxNum' with value 9997,000 at accessor Demeter::Data::bkg_pre1 (defined at /home/frederik/perl5/lib/perl5/x86_64-linux-gnu-thread-multi/Demeter/Data.pm line 258) line 7

    eval {...} at /home/frederik/perl5/bin/dathena line 31

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!
