I have a question about the initialization of the TRandom3 random number generator.
I have a code that generates a set of N random numbers with TRandom3 (N is a parameter that can be chosen by the user, and TRandom3 is initialized in the code with SetSeed).
If for instance I set N=100 events, the code will generate a given sequence of 100 random numbers (that depends on the seed of TRandom3). Now, I want to obtain the same sequence of random numbers by running the code twice with N=50. To do that, I guess that the first time TRandom3 has to be initialized with the same seed that I used in the run with N=100, but what about the second initialization?
