mne.make_sphere_model¶

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)[source]¶

Create a spherical model for forward solution calculation.

Parameters:

Parameters:	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()` and Logging documentation for more).
Returns:	sphere : instance of ConductorModel The resulting spherical conductor model.

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
