<div>Please use ft_connectivityanalysis with cfg.method = ‘wpli’, and an appropriate fieldtrip-style data structure, containing fourier coefficients (i.e. output of ft_freqanalysis with cfg.output = ‘fourier’);</div>

<div>Otherwise, if you insist on using the lower-level function ft_connectivity_wpli, please read the documentation.</div>
