[Gate-users] how to set MU prescription dose lines

hi,
  I  do not know the relation between "setTotalNumberOfPrimaries" of simulation  and  MU prescription dose in the external radiotherapy . How should  I set the number of the photon or events in simulation that the absorbed depth dose in phantom will arrive at a expected value. In addition , in Selective bremsstrahlung splitting (SBS) technology, the final state of the process is generated N times and the weight of each secondary is 1/N. Does it divide the energy of photon ( original produced by the bremsstrahlung)  into N pieces of energy ,and then get  single photon with original  energy of 1/N in  the same direction ?
 Thank you for attention?
yours sincerely,
Bin
