Dear Vladimir, Rik & MEG users,
Given that we aquire subject-specific structural MRIs for the MEG head models, what would be the preferred way of specifying our digitized fiducial points for nasion, lpa and rpa in structural MRI space ? Would you recommend the 'select' option and use SPM's hardcoded locations or use more precise information by including e.g. vitamin E capsules in the structural image and use the 'type' option to select the MNI coordinates in the normalized MRIs.
Also, would you recommend using head shape point ? Our system is the new Elekta Neuromag Triux.
