The water cube is divided into slices using class '''G4PVReplica'''. At each slice the deposited dose and energy for every energy beam is computed. The energy and the dose are scored using classes '''G4UserSteppingAction''' and '''G4UserRunAction'''. The proton beams are simulated using '''G4ParticleGun''' class. There is an option to chose among several '''EM''' and the '''QGSP_BIC_EMY''' physics lists. | The water cube is divided into slices using class '''G4PVReplica'''.
