@Francois, I am able to create a head model with the 3-shell sphere option from my mixed cortex + subcortical surface. Then I click “Compute sources [2018]” for one of my stimulus conditions and on “MN: EEG(Mixed) 2018” I right click and click on “Cortical activations” but nothing is there, in any of the displays. I see no activations anywhere. Does this indicate what a problem might be?
