[FieldTrip] connectivity/amplitude correlation

[Karl Doron]

Hi Lilla,

There is a reference for Rosenberg et al, 1998 for the partialization method in the code itself but I'm not seeing any in the help section. 

Thanks,
karl

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.
