Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_headmodel_singlesphere”.
FT_HEADMODEL_SINGLESPHERE creates a volume conduction model of the head by fitting a spherical model to a set of points that describe the head surface. For MEG this implements Cuffin BN, Cohen D. "Magnetic fields of a dipole in special volume conductor shapes" IEEE Trans Biomed Eng. 1977 Jul;24(4):372-81. Use as headmodel = ft_headmodel_singlesphere(mesh, ...) Optional arguments should be specified in key-value pairs and can include conductivity = number, conductivity of the sphere See also FT_PREPARE_VOL_SENS, FT_COMPUTE_LEADFIELD
