Source estimation options

We are currently revisiting the way unconstrained sources are handled in the connectivity functions.
@Raymundo.Cassani is working on a new connectivity tutorial that will explain all these aspects.

@Raymundo.Cassani I kind of lost tracks of the recent conclusions, and I'm not sure whether we still need to update things in the code or not...
Can you please explain here how to obtain the optimal results with current functions?
Thanks
