Rename EEG channels🔗


This example requires the meg_wiki package to download the sample dataset. This package can be installed with pip:

$ pip install git+

The EEG channel are named EEG 001, EEG 002, .. while they actually correspond to a standard 10/05 naming. The EEG channel layouts are available in this section.

from matplotlib import pyplot as plt
from mne import set_log_level
from import read_raw_fif

from meg_wiki.datasets import sample
from meg_wiki.eeg import load_mapping_64chs

fname = sample.data_path() / "eeg-layout" / "meg-eeg-raw.fif"
raw = read_raw_fif(fname, preload=False).pick("eeg")
Measurement date January 01, 2000 00:00:00 GMT
Experimenter mne_anonymize
Digitized points 435 points
Good channels 64 EEG
Bad channels None
EOG channels Not available
ECG channels Not available
Sampling frequency 1000.00 Hz
Highpass 0.10 Hz
Lowpass 330.00 Hz

The mapping between the channel number and name in the standard 10/05 naming convention can be loaded and applied to the MNE object. The EEG channels can be visualize inn their true digitized location through the DigMontage attached.

f, ax = plt.subplots(1, 2, figsize=(16, 8))
ax[0].set_title("Original channel names")
ax[1].set_title("Standard 10/05 channel names")
# plot original channel names
raw.get_montage().plot(axes=ax[0], show=False)
# rename EEG channels
mapping = load_mapping_64chs()
# plot renamed channel names
raw.get_montage().plot(axes=ax[1], show=False)
Original channel names, Standard 10/05 channel names
