How to use data in neural ensemble (NEO) format#
This example shows how to create an MNE-Python Raw
object from data
in the neural ensemble format. For general
information on creating MNE-Python’s data objects from NumPy arrays, see

import neo
import mne
This example uses NEO’s ExampleIO
object for creating fake data. The data will be
all zeros, so the plot won’t be very interesting, but it should demonstrate the steps
to using NEO data. For actual data and different file formats, consult the NEO
documentation.
reader = neo.io.ExampleIO("fakedata.nof")
block = reader.read(lazy=False)[0] # get the first block
segment = block.segments[0] # get data from first (and only) segment
signals = segment.analogsignals[0] # get first (multichannel) signal
data = signals.rescale("V").magnitude.T
sfreq = signals.sampling_rate.magnitude
ch_names = [f"Neo {(idx + 1):02}" for idx in range(signals.shape[1])]
ch_types = ["eeg"] * len(ch_names) # if not specified, type 'misc' is assumed
info = mne.create_info(ch_names=ch_names, ch_types=ch_types, sfreq=sfreq)
raw = mne.io.RawArray(data, info)
raw.plot(show_scrollbars=False)
