Matlab code
%% Structure for BEM volume conduction model
%% Each layer mesh is indexed by k
% vol.bnd(k).pnt. : vertices for mesh "k"
% vol.bnd (k).tri : triangles for mesh "k"
% %% Set the conductivities of each domain
% vol .cond : conductivities
%% EEG electrodes
% sens.pnt : locations of electrodes
%% Positions of the dipoles
% pos :locations of dipoles
%% Compute the BEM
% choose BEM method (OpenMEEG, BEMCP or Dipoli)
cfg.method = 'openmeeg';
% Compute the BEM matrix
vol = ft_prepare_bemmodel(cfg, vol);
cfg. vol = vol;
cfg. grid. pos = pos;
cfg. elec = sens;
% Compute leadfield
% with no orientation constraint
lf_openmeeg = ft_prepare_leadfield(cfg);
