[Mutanga Theodore]

Here is yet another error :
  ...
nx ny nz: 512 512 47
dx dy dz: 9.766e-01 9.766e-01 3.348e+00
terminate called after throwing an instance of 'std::bad_alloc'
  what():  St9bad_alloc
Abort


I get that even from using the example for voxelized phantom source en
GATE examples.

Please someone help on this error message

Regards

Theo
