How I can calculate and plot the Biological SOBP

Hi Geant4 Administrator/Expert

I am a novice user of Geant4. I just came to G4 forum today.

By looking at the past questions, I saw an answer about getting SOBP.

I consulted the related files in the hadrontherapy folder, but I was not able to successfully get SOBP.

Can someone tell me how I should operate?

Any reply would be very helpful to me.

your sincerely,
Yuri
