[Gate-users] Coincidences output (many times : the same coincidence event is taken two times)

Hi Marlen! 

Did you use the command line : /gate/digitizer/Coincidences/allPulseOpenCoincGate true ?
try this command line like this :

# Coincidence sorter
/gate/digitizer/Coincidences/allPulseOpenCoincGate true
/gate/digitizer/Coincidences/setWindow 20 ns
/gate/digitizer/Coincidences/MultiplesPolicy  takeAllGoods
......

I tried it in two different computers, and I found the same problem

Looking forward to your answer
Many thanks

Ashley
