Units for ephys.stimuli?

[michmgee]

I'm pretty new to this, so it might be something that is implied or that I don't know where in the documentation to look. What are the units for the step input amplitudes?

I frequently see code that looks like this in the examples. When I see ('step1',10) is that 10 pA?

for protocol_name, amplitude in [('step1', 10)]:
stim = ephys.stimuli.NrnSquarePulse(
step_amplitude=amplitude,
step_delay=100,
step_duration=500,
location=soma_loc,
total_duration=700)

Thanks very much!

They are in nA, per https://bluepyopt.readthedocs.io/en/latest/ephys/bluepyopt.ephys.stimuli.html#bluepyopt.ephys.stimuli.NrnSquarePulse

In python, you can access the documenation for a function by doing:
help(ephys.stimuli.NrnSquarePulse), which should give:

>>> from bluepyopt.ephys.stimuli import NrnSquarePulse
>>> help(NrnSquarePulse)

 |      Args:
 |          step_amplitude (float): amplitude (nA)
 |          step_delay (float): delay (ms)
 |          step_duration (float): duration (ms)
 |          total_duration (float): total duration (ms)
 |          location (Location): stimulus Location

which should help in the future.

Thanks for the tip!
