 +  <a href=/​reference/​ft_voltype><​font color=green>​FT_VOLTYPE</​font></​a>​ 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
