Hello,everyone,
In MNE, how to plot the direction of MEG sensors ? In some examples, only the helmet or position points are displayed, for example:
Brain = mne.viz.get_brain_class()
brain = Brain(subject, hemi=‘both’, surf=‘pial’, background=‘w’,
subjects_dir=subjects_dir, size=(800, 600))
brain.add_sensors(
epochs.info, trans=trans,
meg=[‘sensors’])
But don’t show the direction of MEG sensors.

  • MNE version: 1.6.0
  • operating system: Windows 10

Here’s an example using fsaverage, for your own data you’d need to provide a proper head ↔ MRI transform for trans

import mne
sample_data_folder = mne.datasets.sample.data_path()
sample_data_raw_file = sample_data_folder / "MEG" / "sample" / "sample_audvis_raw.fif"
info = mne.io.read_info(sample_data_raw_file)
Brain = mne.viz.get_brain_class()
brain = Brain(subject="fsaverage", hemi='both', surf='pial', background='w', size=(800, 600))
brain.add_sensors(info, trans='fsaverage', meg=['sensors'])
