[Gate-users] DoseActor not recording any dose (empty 0's files)

[G Tom]

Hi All,

This has been puzzling me all week. I set up my simulation and I can
visualize it working and interactions happening in the phantom to which I
have attached a doseActor.

When I read the output after 10^8 histories, the dose actor recorded only
0s. What could I be missing ?

Thanks

GT

My macro is below and placed just before the /gate/run/initialize line in
my main macro and I start the simulations with
