you don't care. The important thing is that the start time of the job(N)
is the time stop of the job(N-1)

It's better to change the seed for each job

the number of run is defined by : Nrun=TimeStop-timeStart/timeslice
if you dont have mouvement in your simulation, you dont need to have
several runs, so you should define setTimeSlice=setTimeStop-setTimeStart
In each output of your jobs, you will have one run per root file.

I attach the the file combine.C and a mail from Dirk which explain how t
use it.

hope that it will help you
