[Gate-users] voxelized phantom works with Gate 7.0 but not 7.2

[Thomas Funck, Mr]

Hi,


I'm trying to run a simulation with a voxelized phantom in ASCII format. Using Gate-7.0 on vGate-3.0, this works without a problem. However, when I try to run the same simulation on vGate-7.2, no voxels are read in by the voxel reader. I'm running the same .mac in both cases.
