@Francois Can you advise which files I should share to reproduce this gain matrix?
Also, I am able to create a head model with the 3-shell sphere method. But when I click on compute sources for one of my stimulus conditions and look at the results, there doesn’t seem to be anything there. If I right-click and look at Cortical activations, there is nothing there and if I click on Project sources it says “Source and destination surfaces are the same for all the selected files. Nothing to project…” Not sure if I’m doing something wrong.
