Dear Lilla, Marcel and Eric,

it actually is possible to test coherence with the permutation test. in
particular, when you consider only one well chosen reference channel it is
pretty straightforward (the clustering algorithm then considers clusters of
sensors which show an above threshold coherence difference with respect to
the reference channel), especially when you use the new statistical
functions in fieldtrip (still only for in-house use). i'll be happy to
explain it as soon as i'm back from biomag.

yours,

jan-mathijs

ps: it is actually possible to filter your data after you did preprocessing,
by specifying the same options in your configuration as you would have done
in preprocessing. however, beware of filter-ringing.
