[Gate-users] Background noise source

After doing a little bit of digging, I found that the GateNoise.cc file sets the position of the noise according to the command:
If anyone has a trivial solution or any suggestions on how to easily correct this to obtain random positions throughout the crystal, it would be greatly appreciated.

Subject: Background noise source
I am interested in modelling background noise in my SPECT images and I have included the lines below in my macro. Is there a way to include a random spatial distribution for the noise? I expected that the background noise would appear randomly throughout the crystal but all of the counts associated with background noise are located directly in the center of my crystal.
