FT_VOLTYPE
Note that this reference documentation is identical to the help that is displayed in MATLAB when you type “help ft_voltype”.
FT_VOLTYPE determines the type of volume conduction model of the head Use as [type] = ft_voltype(headmodel) to get a string describing the type, or [flag] = ft_voltype(headmodel, desired) to get a boolean value. For EEG the following volume conduction models are recognized singlesphere analytical single sphere model concentricspheres analytical concentric sphere model with up to 4 spheres halfspace infinite homogenous medium on one side, vacuum on the other openmeeg boundary element method, based on the OpenMEEG software bemcp boundary element method, based on the implementation from Christophe Phillips dipoli boundary element method, based on the implementation from Thom Oostendorp asa boundary element method, based on the (commercial) ASA software simbio finite element method, based on the SimBio software fns finite difference method, based on the FNS software interpolate interpolate the potential based on pre-computed leadfields and for MEG the following volume conduction models are recognized singlesphere analytical single sphere model localspheres local spheres model for MEG, one sphere per channel singleshell realisically shaped single shell approximation, based on the implementation from Guido Nolte infinite magnetic dipole in an infinite vacuum interpolate interpolate the potential based on pre-computed leadfields See also FT_COMPUTE_LEADFIELD, FT_READ_VOL, FT_HEADMODEL_BEMCP, FT_HEADMODEL_ASA, FT_HEADMODEL_DIPOLI, FT_HEADMODEL_SIMBIO, FT_HEADMODEL_FNS, FT_HEADMODEL_HALFSPACE, FT_HEADMODEL_INFINITE, FT_HEADMODEL_OPENMEEG, FT_HEADMODEL_SINGLESPHERE, FT_HEADMODEL_CONCENTRICSPHERES, FT_HEADMODEL_LOCALSPHERES, FT_HEADMODEL_SINGLESHELL, FT_HEADMODEL_INTERPOLATE
