[FieldTrip] ROI selection in a GC analysis

Dear fieldtrip experts,
I'm sorry to ask again to the list the same question but I had no answer
and I still have not solved my questions.
I would like to ask you if there is an elegant solution in the
selection/definition of the ROI for a Granger Causality analysis.
Just to explain better my doubts.
Let suppose i've the sources reconstructed in the temporal domain and/or in
the frequencies domain.
If now I wish to perform a GC analysis I should know the ROI or sources on
which to perform it.
As far as I've seen most of them are selected with an a priori knowledge.
I would like to know if there is a way to define the ROI from the data, not
from my (eventually with bias) knowledge.
As far as I've searched the only method developed is the Full-brain
auto-regressive modeling (FARM).
Since there are already ft_mvaranalysis and ft_connectivityanalysis, do
you think that is possible to integrate the FARM approach into those
I'm sorry but I know my limitations and I don't know how to do it.
I hope this could be useful not for me only.
