[FieldTrip] how to implement the pointwise conductivity value to the FEM model in the forward/inverse source problem?

[tingting zhang]

Hi Johannes,
thank you very much for the response and sorry for the late reply. My model has around 200m elements with anisotropic conductivity and actually Im trying that nice suggestion now. Thank you very much ~^^
wish you a nice day.  :)

Dear ting,

the easiest solution would be to define each element of your head model as a separate tissue region. However, this only works if your conductivities are isotropic. For anisotropic conductivities, there should be explanations how to implement these in previous topics on this mailing list.

Best,

Hey Fters,

I have the pointwise conductivity values for each vertex for a FEM head model and I want to solve the forward/inverse source problem using fieldtrip.
But I could not find the way to implement the conductivity on each vertex using fieldtrip because It seems that the conductivity value is assigned to each region of the tissue.
Does anybody know how to implement the conductivity value to the model using fieldtrip?
Thank you very much, Any suggestion will be appreciated.

Best regards,
ting
