Dear nassarasemi,
from the output that you attach I would guess that you are applying the “/run/numberOfThreads 2” command after you have run the “/run/initialize” command in you macro (given that you don’t initialize directly in your main).
What happens if the numberOfThreads command is the first one in your macro?
In case you initialize the run manager in your main, can you try to comment it out and then add the command to your macro?
Best regards
