Get probe from library¶
probeinterface provides a library of probes from several manufacturers on the GitHub platform: https://github.com/SpikeInterface/probeinterface_library
Users and manufacturers are welcome to contribute to it.
The Python module provide a function to download and cache files locally in the probeinterface json-based format.
from pprint import pprint
import numpy as np
import matplotlib.pyplot as plt
from probeinterface import Probe, get_probe
from probeinterface.plotting import plot_probe
Download one probe:
manufacturer = 'neuronexus'
probe_name = 'A1x32-Poly3-10mm-50-177'
probe = get_probe(manufacturer, probe_name)
print(probe)
A1x32-Poly3-10mm-50-177 - neuronexus - 32ch - 1shanks
Files from the library also contain annotations specific to manufacturers. We can see here that Neuronexus probes have contact indices starting at “1” (one-based)
pprint(probe.annotations)
{'first_index': 1,
'manufacturer': 'neuronexus',
'name': 'A1x32-Poly3-10mm-50-177'}
When plotting, the channel indices are automatically displayed with one-based notation (even if internally everything is still zero based):
plot_probe(probe, with_contact_id=True)

plt.show()
