Dear @mksharma_iitk ,
thank you very much for your answer. As I see from here, the distribution of a particle is a single point or a sphere at x=20 cm. How do you store the distribution in a single file, in order to be used with GPS? You mean to define in these files the energy and the direction, in addition to the position?
About the adoption of ParticleGun, how did you generate the random number for the sample?
Thanks in advance for your time.
Best regards,
Christian
