Hello Alex,
I am using freesurfer 5.1.0.
I tried the command mne_setup_source_space --subject im14 --ico 6 --cps --overwrite, however I got the exact same error message as before.
Could this have something to do with the fact, that this subject appears to have some extra tissue right outside the brain in freesurfer?
Thanks for your help,
Maria
Hi Maria,
This was a known problem, and I strongly doubt it is related to your freesurfer reconstruction. It is caused by some safety checks run by MNE. The easy way to avoid it is to use a larger decimation i.e. ico 5. In my experience, you cannot use an ico decimation above a fifth order icosahedron. Alternatively, you can use the full range i.e. 1mm and up of the "--spacing" option.
