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_radiusfloat | 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).
infomne.Info | None: The mne.Info object with information about the sensors and methods of measurement. Only needed if r0 or head_radius are 'auto'.
relative_radiiarray-like: Relative radii for the spherical shells.
sigmasarray-like: Sigma values for the spherical shells.
verbosebool | str | int | None: Control verbosity of the logging output. If None, use the default verbosity level. See the logging documentation and mne.verbose() for details. Should only be passed as a keyword argument.
