the inside and outside detection for dipoles and a halfspace model should be based on - inside if it is on the "tissue" side of the plane - outside if it is on the "air" side of the plane assuming that all dipole points in the grid are inside is incorrect. The problem is in ft_prepare_sourcemodel where it now states if ~isfield(grid, 'inside') && ~isfield(grid, 'outside') if ft_voltype(vol, 'infinite') || ft_voltype(vol, 'halfspace') % an empty vol in combination with gradiometers indicates a magnetic dipole % in an infinite vacuum, i.e. all dipoles can be considered to be inside grid.inside = 1:size(grid.pos,1); grid.outside = [];
