Hello everybody!
my simulations contains detection of optical photons.
when I use /gate/digitizer/Singles/insert opticaladder, my ascii Singles
file is empty. But when I comment the command, ascii single file has the
recordings (is that mean optical photons are not generated ?).
I have set export GATE_USE_OPTICAL = 1 on. (When I source the env_gate.sh I
even get the message 'Transport and generation of optical photons is
enabled')
My materials.xml has properties of LSO and NaI, I tried with both crystals
but didn't work out.
Any help ?
thanks in advance
