[FieldTrip] FEM using Simbio

Dear all,

Has anyone used the FEM approach to Headmodels using Simbio recently?

If so, I get this error:

"Elements have wrong orientation or are degenerated"

Any ideas?

cfg        = [];

cfg.method ='simbio';

cfg.conductivity = [0.33 0.14 1.79 0.01 0.43];   % order follows mesh.tissyelabel

vol        = ft_prepare_headmodel(cfg, mesh);



            hex: [545883x8 double]
            pnt: [569722x3 double]
         labels: [545883x1 double]
         tissue: [545883x1 double]
    tissuelabel: {'csf'  'gray'  'scalp'  'skull'  'white'}
           unit: 'mm'
            cfg: [1x1 struct]

Any help would be highly appreciated.
