Error on running o2-sim using Geant4

I tried to simulate using the command :

o2-sim -m ITS -e TGeant4 -g boxgen -n 10

But I got this error in o2-sim_workerlog():

[04:24:24][INFO] Add ITS alignable volumes
Info in TGeoManager::Export: Exporting FAIRGeom FAIR geometry as root file. Optimizations streamed.
Info in TObject::SetNavigator: TG4RootNavigator created and registered to G4TransportationManager
isMaster=1

Does anyone know how to fix this?

Hi,
when I run o2-sim -m ITS -e TGeant4 -g boxgen -n 10 everything seems fine. I also don’t see any errors in the workerlog. I just loaded the O2 environment with alienv load O2/latest-dev-o2
Cheers,
Ole
