Dear SPM programmers, I decided to move on EEG data :-) and my (old) data come from Neuroscan and are thus in .avg ; but it does not seem possible to import it directly - right? I also have the data in ascii (always useful) .. I would like to know where I can look (documentation or a .m file to know exactly how the data have to be registered in my files and the similarly for the electrodes, how to import the head of the subject - again data in ascii) thank you in advance, best - Cyril
