[Gate-users] Crosstalk and coincidence window

[Devin Van Elburg]

Hello all,

Does anyone know if the crosstalk option only applies to immediate neighbouring volumes, or if there is a secondary effect also? What I means it, if I set crosstalk to my crystal array and put setEdgesFraction to 0.1, would the second neighbouring crystal see a fraction of 0.01, then the next 0.001 and so on?

I also have a question about the window for the coincidence sorter. In all examples I see, the window is set simply with:

/gate/digitizer/Coincidences/setWindow X Y

However, whenever I attempt this, the command isn't found. Furthermore, the tree up to /gate/digitizer/Coincidences isn't found when I look in qt mode. I can set the window if I first name and insert a coincidenceSorter. Do I not have the Coincidences branch because I do not have updated versions of my programs? I am using Gate v7.1, Geant4.10.01 (not the patch), root 5.34.30, and gcc 4.8.2. I am using the internal CHLEP library.

Thanks for your help,
Devin Van Elburg
