Timer

class Timer

Syntax:

timer = h.Timer(python_func)

Description:

Execute a Python function at the end of each interval specified by timer.seconds(interval). The timer must be started and can be stopped. A Timer is used to implement the NEURON Main Menu ‣ Tools ‣ MovieRun in nrn/lib/hoc/movierun.hoc

Warning

This code must be run with nrniv -python and not directly via python. The better solution is to use Python’s threading module which works regardless of how NEURON is launched.

Example:

from neuron import h

def foo():
    print 'Hello'

timer = h.Timer(foo)
timer.seconds(1)
timer.start()
# type timer.end() to end timer

Timer.seconds()

Syntax:

interval = timer.seconds()

interval = timer.seconds(interval)

Description:

Specify the timer interval. Timer resolution is system dependent but is probably around 10 ms. The time it takes to execute the Python function is part of the interval.

---

Timer.start()

Syntax:

timer.start()

Description:

Start the timer. The Python function will be called at the end of each interval defined by the argument to timer.seconds(interval).

---

Timer.end()

Syntax:

timer.end()

Description:

Stop calling the Python function. At least on Linux, this will prevent the calling of the function at the end of the current interval.
