[Gate-users] Random Numbers

[Richard Taschereau]

Hi Sane,

If you change the energy window you are going to select different events,
which alters the execution path of your simulation and ultimately will yield
different results.  Remember that random numbers are used throughout GATE
and GEANT from particle emission (energy, position, direction), to blurring
etc.  You could use digigate for your needs.
