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
- r0array_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 appropriate radius from the dig points in Info, If None, exclude shells (single layer sphere model).
- infoinstance of
Info|None Measurement info. Only needed if
r0orhead_radiusare'auto'.- relative_radiiarray_like
Relative radii for the spherical shells.
- sigmasarray_like
Sigma values for the spherical shells.
- verbosebool,
str,int, orNone If not None, override default verbose level (see
mne.verbose()and Logging documentation for more). If used, it should be passed as a keyword-argument only.

- Returns
- sphereinstance of
ConductorModel The resulting spherical conductor model.

Notes
The default model has:
relative_radii = (0.90, 0.92, 0.97, 1.0) sigmas = (0.33, 1.0, 0.004, 0.33)
These correspond to compartments (with relative radii in
mand conductivities σ inS/m) for the brain, CSF, skull, and scalp, respectively.New in version 0.9.0.
