[Gate-users] reading source from a file

[Sebastien JAN]

Hi Ahmet,

You need to develop your specific method in GateGeneralParticleSource 
and GateGeneralParticleSourceMessenger (if you want to develop a 
messenger interface).
The method GateGeneralParticleSource::GeneratePointsInBeam() could be 
used as an example.
Finally, your method will return the "particle_position" variable which 
will called by 
GateGeneralParticleSource::CreatePrimaryParticles(G4PrimaryVertex* vertex).

Hope this help
Cheers
Sebastien
