[Gate-users] Interpreting Hits Information in GATE

[Paola Solevi]

Hello,
both hits and coincidences have an eventID flag that determine the event 
number (i.e. the back-to-back gamma event) that has been detected.
I suppose you can read the eventID of the coincidence and select by means 
of the same eventID the associated hits information.

I hope this help,
 	Paola
