print(__doc__)

data_path = data_path()
fname = op.join(data_path, 'MEG', 'sample', 'sample_audvis_raw.fif')
raw = mne.io.read_raw_fif(fname)
subjects_dir = op.join(data_path, 'subjects')

Here we use :func:mne.viz.plot_trans with trans=None to plot only the surfaces without any transformations. For plotting transformation, see tut_forward.
