mne.viz.snapshot_brain_montage#
- mne.viz.snapshot_brain_montage(fig, montage, hide_sensors=True)[source]#
Take a snapshot of a PyVista Scene and project channels onto 2d coords.
Note that this will take the raw values for 3d coordinates of each channel, without applying any transforms. If brain images are flipped up/dn upon using
imshow
, check your matplotlib backend as this behavior changes.- Parameters:
- figinstance of
Figure3D
The figure on which you’ve plotted electrodes using
mne.viz.plot_alignment()
.- montageinstance of
DigMontage
orInfo
|dict
The digital montage for the electrodes plotted in the scene. If
Info
, channel positions will be pulled from theloc
field ofchs
. dict should have ch:xyz mappings.- hide_sensors
bool
Whether to remove the spheres in the scene before taking a snapshot. The sensors will always be shown in the final figure. If you want an image of just the brain, use
mne.viz.Brain
instead.
