I am currently trying (and failing) to simulate the following scenario: - A voxelized phantom defined via a CT dataset in Analyze format. - A source placed inside the phantom. - A simple detector aiming towards the source. The problem I'm facing occurs when I place the detector inside the bounds of the voxelized phantom: When outside the bounds, the detector registers hits as expected. As soon as I move it inside the bounds, however, no hits are registered. Is this a known limitation or am I doing something wrong? I'm using the latest develop Gate on Ubuntu 16.04, CPU-only single core simulation. You may find all the relevant short scripts including the CT dataset here (17MB tgz):<a href="https://drive.google.com/open?id=0BzM9gTEQ3DYyYWFOcVRibklGdVk" target="_blank" id="LPlnk281784" class="x_OWAAutoLink"> https://drive.google.com/open?id=0BzM9gTEQ3DYyYWFOcVRibklGdVk</a> Use runSim.sh to run the simulation (you may need to change the Gate binary's name in the script). If anyone has any tips or pointers, they would be very much appreciated.
