I got an error when clicking on the "compute head model". I have selected the 10-20 system image as EEG positions for EEG channels.

Hi ddaschakladar,

Welcome to the forum, how does your anatomy structure look like. This error tells you there is no cortical surface defined yet. You get that error when for example only the MRI is loaded as in :

You need the MRI segmented into the cortex, skull, scalp etc, so your folder has more elements like this.
