[FieldTrip] DICS: ft_sourceanalysis - why headmodel is necessary? Leadfield is not sufficient?

[Michał Komorowski]

Hello,

I am using ft_sourceanalysis to analize EEG signal using DICS method (
https://www.ncbi.nlm.nih.gov/pubmed/11209067).

I wonder why headmodel is needed to be passed to cfg to ft_sourceanalysis
even though the correct leadfield is provided? In the equations for DICS
there is only a leadfield needed, not a headmodel.

Best regards,
Michał
