problem partially solved

[Andrew Smart]

Hi,
I found why I was getting the error
embarrassingly I had {i} instead of {:}!

My general question remains about the possibility of doing statistical group
analysis on coherence between BESA dipoles, or in source space in general.

It seems most of the coherence analyses are set up to do coherence between
channels and an external reference such as EMG. 

Thanks and sorry for all the messages!
