After we did the source analysis, where we can konw the precision or the error?
Run simulations with position of known dipoles.
Or refer to the existing literature on inverse modeling.
For evaluating the error between the original signals and the modeled signals:

The notion of resolution can be systematically defined/quantified with the linear imaging operators in Brainstorm. There is a new preprint that just came out on the topic.
What do you think @Francois?
