However, the results are better with the default parameters than with ‘Edge Constant=0.63’ and ‘Erosion Size=2’. If we do what you recommend on this MRI, there is a part of the frontal lobes that is not classified as brain and that is not included in the final cortex surfaces.
Can you please double-check this and then delete the comment you added again on the Brainstorm tutorial?
Thanks
