Dear Dr. Vladimir and SPM experts,
thanks your help. could you tell me if I use convert button to import .cnt
data, which spm script I should change the autodetect to ns_cnt32 ?
I also have another question. I use EEGlab and make epoch from continous
EEG and save it as .set data. when I use spm8 to convert this data, it can
import it but the display of epoch EEG is wrong. all channels data crowd in
together. is there any thing wrong ?
thanks your help
