[gate-users] voxelized phantoms Gate 1.2

[Mutanga Theodore]

Hi Ziad,

Thanks for the suggestion but Im running the same version of Geant4 6.2p02
which is recommended for Gate 2.1 and root 4.04.
Whad did you mean by swapping ? I am running GATE on the cluster and it is
version 2.1 thats installed. I had tried Gate 2,2  on another cluster and
I couldn't run Gate with voxelized phantom and sources. I got the errors I
had mentioned on a previous post about bad allocation. Do you have some
macros that work let me try them out  and see..


cheers

Theo
