I just learn about the tutorial āHead model and forward computationā, which use āsampleā to generate a volume src. Here is the plot of sampleās bem.
tutorial of Head model and forward computation
Since I want to get source localization using eeg only, I try to use āfsaverageā to do the same job, so that it can provide the location of montage of ā10-20ā.
But I get fsaverageās bem like THAT:
Looks like I got the wrong āouter_skullā, since it was attached to the outer_skin. itās really different from the plot of tutorial.
Was it right?
here is my code:
surface = 'C:/Users/xuesiyang/mne_data/MNE-fsaverage-data/fsaverage/bem/inner_skull.surf'
plot_bem_kwargs = dict(
subject='fsaverage', subjects_dir=fs_dir,
brain_surfaces='white', orientation='coronal',
slices=[50, 100, 150, 210])
vol_src = mne.setup_volume_source_space(
subject='fsaverage', subjects_dir=fs_dir, surface=surface,
add_interpolator=True) # Just for speed!
print(vol_src)
mne.viz.plot_bem(src=vol_src, **plot_bem_kwargs)
