[FieldTrip] connectivity/amplitude correlation

Maybe your version of FieldTrip is older, and therefore, it does not
contain the references yet. You can check the reference documentation of
ft_connectivity_corr on the FieldTrip wiki:
(The reference documentation of the functions is always automatically
updated according to the latest version of the documentation part (or
"help" part) of the script.)
The same articles (and more) can be found also under Literature (Method
the title Connectivity Analysis.
I have not read the articles myself, so I am not sure if they give the
information you need. But I was just wondering if you are aware of the
recently available documentation of the function.

I would specifically like to confirm (for a pending publication) how the amplitude correlation is computed when the function is given output from ft_freqanalysis which contains a time dimension (relevant cfg parameters pasted below). I've assumed this is occurring in the frequency domain across trials for sensor i and sensor j.
