[Gate-users] How to specify a Gaussian sampling over the source?

[S. Saghamanesh]

Hi everybody,
I want to define an extended photon source which should be sampled based on a Gaussian function. But it seems there isn't such a capability in gate! As I found out, one can just select the type (Point, Plane, Volume) and then the shape (rectangular, ellipse, cylinder, ...) of the source. And the gate would sample uniformly over the source. What about if we need a non-uniform (Gaussian) sampling of particles? Does anybody have a clue on this problem?I remember that in MCNP code, that's possible easily.
Thanks in advance
Somayeh
