[Gate-users] missing event IDs in hits file

[Rajaram, Ramya (H USA)]

Hi Marlen,

I think that could be the case for an isotropic source. However, I have set the source to be a unidirectional point source (shooting gammas at the detector along a single angle) by restricting the theta and phi values. Wouldn't that mean all particles must hit the detector?

Thank you for your help,

Ramya

Hi,

Maybe this is, because some events don't hit the detector but leave the 
"World" without any interaction in sensitive detectors?

Kind regards,
Marlen
