[FieldTrip] Restricting dipoles to cortex

[tim.redepenning at uni-bielefeld.de]

Dear community,

 

I am currently working with functional connectivity (EEG data) with eeglab
and a plugin called SIFT. The source estimation is based on dipole fitting
which relies on fieldtrip scripts. 

Now, lots of the dipoles are placed too deeply into the brain what makes my
results -at least- questionable. Is there a way to restrict the dipole
fitting to the cortex surface? Or is this rather an issue of the following
source estimation and less of the dipole positions?

 

Best wishes

Tim
