[Gate-users] Coincidences with generic repeater

[Leo Read]

Hi Antonio,

I have also noticed that coincidences are not generated when the generic
repeater is used. I did not find any solution to this on the forum.

As a result, I'm writing C code to generating coincidence data based on
hits data in the root output. I have personally found that I don't like how
Gate generates singles output based on the hits output - it doesn't seem to
handle inter-crystal events properly. If you are OK with ignoring this
effect, then you may want to look into looping over the singles data and
generating your own coincidence data.

If anybody has an alternative solution, please share your thoughts.

Thanks!
