[Gate-users] GATE running problem--WARNING : positron found and photonID vector size 1

[Su, Yi]

Hi there,

I am running a GATE simulation and the following warning message keeps popping up:

[GateTrajectoryNavigator::FindAnnihilationGammasTrackID]  WARNING : positron found and photonID vector size: 1

Does anyone know what is going on, and what might be the problem? I am using Gate 3.1.2 and I am simulating an ecat system with a simple cylinder phantom and source.

Thanks a lot,

Yi
