[NEST Users] Re: Replay Poisson input

I assume you want to run the simulation in a loop and provide the same Poisson input for every round through the loop? If the Poisson input is the only randomness in your simulation, i.e., you have no noise generators, no neurons with probabilistic spike generation or the like, then you could reset the nest random number seed for each round. In this case, you should use one seed value for the build phase (assuming you use some probabilistic connection rule) and then a different seed for the noise: nest.rng_seed = 123 nest.Create( ... ) nest.Connect( ... ) for sim_round in range(10): nest.rng_seed = 456 nest.Simulate(1000) I believe this should work, but please test carefully before using this approach, I might have overlooked something.
