Created attachment 727 Script/Data To explore the possibility to use fieldtrip/simbio to model current spread of deep brain stimulation electrodes, I was already in contact with R. Oostenveld and we discussed some initial points offline. The current state is that I can generate a headmodel describing only a small area of the brain that surrounds the DBS electrode and can generate a mesh using ft_prepare_mesh. Once I pass this mesh into ft_headmodel_simbio, I get an error stating: Error using sb_calc_stiff (line 80) Elements have wrong orientation or are degenerated Error in ft_headmodel_simbio (line 89) vol.stiff = sb_calc_stiff(vol); I attached a script and some empirical data which one can run to reproduce this. Thank you for any suggestions, Andreas
