hi
my problem: dt jumps to 1e+9 at the beggining of the simulation, and the simulation does not run. At that point i can change the dt and go on with the simulation with "continue for". Any suggestion to overcome this would be very welcome.

What is dt before finitialize() or run() is called? Are you using fixed time step or adaptive integration ("cvode")? Are you using the standard run system or your own main computational loop? What version of NEURON are you using, and under what OS?
