Dear experts,
Is it always advised to do the 'average reference' for MEG-only data in the preprocessing step before 3D source localization in SPM8? - and if so is there an equivalent of the automatic 'spm_eeg_reref_eeg' script for average rereferencing of MEG-only data?
My data is from a Neuromag scanner, and contains magnetometers and gradiometers both - does this make a difference to how I should do the average reference?
(Apologies if I have missed this information when searching the manual or past maillist posts)
Many thanks for your advice,
Nela
