Hi,
I am having the same persistent problem trying the co-registration of my EEG data with the MRI, which occurs both during the the "Prepare > Co-registration", and during the "MRI-co-registration" processes. The same problem happens with different eeg formats (edf, bdf, cnt, .egg, ...) or sensors files (.sfp, .loc, .sph, ...), or adding the landmarks (nas,lpa,rpa), etc.
Maybe someone can help me. Thanks in advance,
Javier
