Summary
In order to co-register a Freesurfer reconstruction with the digitizer points from an M/EEG dataset (per the documentation and slideshare), the user needs to launch mne coreg and run the ICP algorithm from the GUI. Looking at the source, it appears that it’s not possible to run the co-registration in a non-gui mode - I assume this was a design choice since the majority of users will want to visually inspect the results of the co-registration.
Not making a feature request; just trying to get a feel for what’s currently possible in MNE and what would be better left to other utilities, e.g. Open3D (possibly).
