[FieldTrip] Dipole fitting

[Oostendorp, T.F. (Thom)]

Hi Sara,

I understand now from Jan-Mathijs that this is not implemented in dipolfitting.m. That script calls dipole, but only to make it perform forward computations. The program can also do the inverse, but dipolefitting,m does not implement that.

So the show answer to your question is: you cannot.

Cheers,
Thom

Hello,
I'm Sara and I have a question regarding an answer I obtained from one of you (Thom) regarding the possibility to keep fixed/or not the location and the orientation of the dipole in the inverse modeling.
The answer was the following:

Actually, the choice is between:
- a moving dipole, i.e. at each sample time a new location is fitted
- stationary dipole location and  free orientation, i.e. the best single position is fitted, but dipole orientation is free at each sample time
- stationary dipole location and stationary orientation, i.e. both location and orientation are fixed in time.

Looking in the details of the dipolefitting.m it is not clear to me how to implement the third option (for the first I know it has to be used the option cfg.model='moving', for the second cfg.model='regional').
Could you help me?

Regards,
Sara
