Hi Petia,
just for your information, the 'voltmeter' is just a pre-configured
'multimeter' that is set to record the voltage. It's only briefly mentioned in
the mulitmeter documentation.
cheers,
Jessica

Thank you Hans!
Actually we used multimeter. In NEST documentation exact information about voltmeter is
missing or we did not discovered it.
Best, Petia

Hello Petia,
I am not quite sure if I understand your problem. The voltmeter records time, sender and
voltage for each data point. In the following example, it records the voltage of two
neurons. Then
voltmeter.get('events')
returns
{'senders': array([1, 2, 1, ..., 2, 1, 2]),
'times': array([ 1., 1., 2., ..., 998., 999., 999.]),
'V_m': array([-68.56875477, -70. , -67.27371053, ..., -69.89028023,
-57.39686729, -69.90055242])}
Entries in the senders, times and V_m arrays correspond to each other, so you can group
data by sender.
Also when recording to file, sender information is recorded:
# NEST version: 3.5
# RecordingBackendASCII version: 2
sender time_ms V_m
1 1.000 -68.569
2 1.000 -70.000
1 2.000 -67.274
2 2.000 -70.000
Best,
Hans Ekkehard
