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
