If your computation produces complex data the (F)FT will be the basis
for coherence, but what is cross-coherence ?

Which part isnt different ? (Yes, the raw data *g*)
Ask better questions - like: My hypothesis is... and because ... I ll
use EEG. I assume EEG-parameter(s) ... is (are) sensitiv for it. My
