You should post your macro and some complementary details about your voxelized volume(s)

Objet : Re : [Gate-users] problem for Cubic voxelized source: Voxel reader

Dear all,

I am trying NCAT phantom in GATE.
I used example_TimeActivityCurve for it.

I could visualize a voxellized phantom.f
However, it cannot be emitted gamma ray.
I suppose that I have some problem for Cubic voxelized source as
followineesoon.g:
[*G4]   Voxel reader ---------->   number of voxels       : 0
*The number of voxels is 'zero', so it causes for this.

I do not know what I can fix.
Please any advice.


With best regard,
Heesoon Sheen
