Description mattiuzzi 2001-02-19 11:34:45 CET 
I'm building an example in which the volumes of the readout geometry DO NOT
touch. I had to change

G4SmartVoxelHeader::BuilReplicaVoxels lines 230:231

  fminExtent= -(width + offset) * nReplicas * 0.5;
  fmaxExtent=  (width + offset) * nReplicas * 0.5;

to allow for these RO geometries...

original is

  fminExtent= -width*nReplicas * 0.5;
  fmaxExtent=  width*nReplicas * 0.5;

If offset if > 0.05 of the size that causes an exception...

The specifications for G4PVReplica foresee that a replica is 'slicing' the
mother volume and therefore the whole mother volume must be filled by replicas
and have no offsets. You should use placements instead in your case.
