[gate-users] voxelized ncat phantom

[Uday Tipnis]

Thank you Richard, for your help. Unfortunately, the result is same as 
before. No output to gateCoincidences.dat and in addition the following 
warning is printed out repeatedly as Gate executes:

WARNING - G4Navigator::ComputeStep()
          Track stuck, not moving for 10 steps
          in volume -ncatVoxel_PVP- at point (0,0,0)
          direction: (0.1756728169,-0.2647301816,-0.9481861591).
          Potential geometry or navigation problem !
          Trying pushing it of 9e-10 mm ...

Any ideas anyone?

Thanks,
Uday
