[Gate-users] number of annihilation events

[Patay Gergely]

Hi Imre,

it might be an overkill, but you can dump _all_ the particle histories to stdout 
with the Geant command
/tracking/verbose 2

After that you can extract the annihilation events (or anything you want), e.g.

Gate yourmacro.mac | grep "annihil" | wc -l

(note that the massive I/O significantly slows down the simulation).

cheers,
