mne.make_sphere_model(r0=(0.0, 0.0, 0.04), head_radius=0.09, info=None, relative_radii=(0.9, 0.92, 0.97, 1.0), sigmas=(0.33, 1.0, 0.004, 0.33), verbose=None)

Create a spherical model for forward solution calculation


r0 : array-like | str

Head center to use (in head coordinates). If ‘auto’, the head center will be calculated from the digitization points in info.

head_radius : float | str | None

If float, compute spherical shells for EEG using the given radius. If ‘auto’, estimate an approriate radius from the dig points in Info, If None, exclude shells.

info : instance of Info | None

Measurement info. Only needed if r0 or head_radius are 'auto'.

relative_radii : array-like

Relative radii for the spherical shells.

sigmas : array-like

Sigma values for the spherical shells.

verbose : bool, str, int, or None

If not None, override default verbose level (see mne.verbose).


sphere : instance of ConductorModel

The resulting spherical conductor model.
