[Gate-users] Coincidences in System "scanner" or "PETscanner"

[Marlen Sellesk]

Hello Gate-Users,

I want to simulate a system "scanner" and get the ASCII-output with the 
coincidences. So I read, that for that I have to define "PETscanner" as 
system (only with "scanner" I get error that the command
/gate/digitizer/Coincidences/setWindow 125. ns
is not found).
In the output I set
/gate/output/ascii/setOutFileCoincidencesFlag 1
and I gate an gateCoincidences.dat, but this file is always empty.
Also in my root-output the Coincidences-Tree exist, but is empty.
So I found in the Users-Talk archive that I have to add
/gate/digitizer/insert coincidenceSorter
but with this it also doesn't work.
Still I get only empty files.
Can anybody help me? Does anybody know, how to do and how to solve this 
problem?
Thanks in advance.
