Hi,
is there a way to get all the info on a particle, step by step at simulation time, when using TGeant4? I need to follow the particle, with process, position, energy loss. I managed to get them with TGeant3 (with the function Gpcxyz()), and I got these lines:
**** GTRIGI: IEVENT= 1 IDEVT= 1 Random Seeds = 4357 0

That' s what I need, but I don' t know how to do it with TGeant4. Maybe there is some function in VMC, but I couldn' t find it.
Does anyone know how can I do?
Thank you in advance!
Lia.
