[FieldTrip] non parametric statistics on connectivity data

[Julian Keil]

Dear Bart,

one way to plug freq x chan x chan data into the statistics functions requiring freq x chan is to restructure your data to channel combinations, in a way that you end up with chan times chan elements in a freq x chan matrix.
Of course you'll have to create new labels for your new channels.

Hope this helps, if you need more specific advise, let me know.

Best,

Julian
