Thanks! I'm a bit confused to the phase space file. So this is a file that gets generated after I run medical_linac? How do I generate it initially in order to use it to reduce computation time?

So to clarify, in order to save time, say to simulate 1 billion particles, I would need to run medical_linac, then this generates a phase space file. Then later on, if I need to simulate 1 billion particles again, I just use this phase space file to save time. Is this correct?

Thanks, Henry
