Dear whom it may concern,

I tried to run a binary neutron star merge simulation with Einsteintoolkit on the workbench . And I mainly followed the tutorial (CactusTutorial.ipynb) and only changed the version of Einsteintoolkit from ET_2017_06 to ET_2018_02 in order to get the thorn NSTracker which is mentioned in https://einsteintoolkit.org/gallery/bns/index.html.
However after I executed the code with the command:

./simfactory/bin/sim create-run nsns_test --parfile=par/nsnstohmns.par --procs=5 --num-threads=1 --ppn-used=5 --walltime=0:5:0

I got an error as the attached file that thorn NSTracker can not be found.

What step did I make mistake and how can I solve it ?

Best regards,

Chia-Hui
