Strange Track ID is found when I use Geant4.6.2p02 to simulate positron annihilation:
The TrackID of gamma are Traced. In my case, Track ID == 1 is the positron, Track ID == 2 is gamma A, Track ID == 3 is gamma B; Three gamma generation is rejected in the tracing code.
However, during the event (begin to end), the Track ID of gamma sometimes is mult 3 , and mult 4; sometimes is multi 2 or multi 3 only.
It doesn't look feasible. Can some one give me a hint? Thanks in advance!
