[FieldTrip] Question about Head Model

[WangJing]

HI everyone,


 


    When I build head model,I encount some questions.


    1.for two Functions ft_volumereslice and ft_volumerealign,which should be run firstly?


    2. when surfaces are created at the boarders of the different tissue-types by the ft_prepare_mesh function. how to determine the parameter cfg.numvertices?


    3.when I build the head model,using the following codes:


     cfg        = [];
     cfg.method ='dipoli';
     cfg.cond =[0.3300 0.004125 0.3300];
     vol        = ft_prepare_headmodel(cfg, bnd);


     


the error message is:


 


??? Error using ==> surface_nesting at 26
the compartment nesting cannot be determined


Error in ==> ft_headmodel_dipoli at 84
order = surface_nesting(vol.bnd, 'outsidefirst');


Error in ==> ft_prepare_headmodel at 226
      vol = ft_headmodel_dipoli(geometry,'conductivity',cfg.conductivity,'isolatedsource',cfg.isolatedsource);


Error in ==> Myheadmodel at 5
vol        = ft_prepare_headmodel(cfg, bnd);


 


   I don't know where is wrong.who can help me? Thank you!


 


Best Regards,


Jing Wang
