hi,
still on the no coincidences error..
I found out there are some error
command </gate/output/root/setRootHitsFlag 0> not found
command </grdm/verbose 0> not found
command </gate/stacking/verbose 0> not found
command </gate/event/verbose 0> not found
therefore I get the Hits has lots of entries.
buy why the coincidence empty ???
regards

Hello,
what kind of PETscanner do you have?
Is it a full ring or a double head scanner?
If it is a double head scanner, maybe it has something to do with
minSectorDifference?
Maybe this works: /gate/digitizer/Coincidences/minSectorDifference 1
Kind regards,
Marlen
