 As you can see you can easily change a few key parameters of the simulation such as runtime, or the Poisson firing rate. It's always a good idea to export some paramters of your code through command line arguments. How this is done will become clearer in the examples. Things that require less flexibility, such as the structure of your simulation itself will be fixed in the simulation file, which is a file with C++ code. Let's have a look at this code in the present example now. As you can see you can easily change a few key parameters of the simulation such as runtime, or the Poisson firing rate.

 here ''run'' takes at least one parameter which is the simulation time ''simtime''. That is one second in this example. The second parameter is optional. The ''false'' in the example tells run to ignore the RateChecker that we painfully added in the last step. This does not make much sense here, but neither did the Checker in the first place. We will see that the switch is useful in other examples such as [[sim_background]], where one can avoid checking during a transient priming period. here ''run'' takes at least one parameter which is the simulation time ''simtime''.
