 +  <a href=/​reference/​ft_connectivity_powcorr_ortho><​font color=green>​FT_CONNECTIVITY_POWCORR_ORTHO</​font></​a>​ computes power correlation after removing the
 +  zero-lag contribution on a trial-by-trial basis. This implements the method
 +  described in JF Hipp, DJ Hawellek, M Corbetta, M Siegel, AK Engel. Large-scale
 +  cortical correlation structure of spontaneous oscillatory activity. Nature
 +  neuroscience 15 (6), 884-890.
 +  Use as
 +    c = ft_connectivity_powcorr(mom,​ ...)
 +  The input argument mom should be a NchanxNrpt matrix containing the complex-valued
 +  amplitude and phase information at a given frequency, and the optional key refindx
 +  specifies the
 +  Additional optional input arguments come as key-value pairs:
 +    refindx ​  = index/​indices of the channels that serve as a reference channel (default is all)
 +  The output c is a NchanxNrefchan matrix that contain the power correlation
 +  for all channels orthogonalised relative to the reference channel in the first
 +  Nrefchan columns, and the power correlation for the reference channels
 +  orthogonalised relative to the channels in the second Nrefchan columns.
