Dear ft community, <br>
<br>
I am looking for an equivalent of imaginary coherence (Nolte, 2004),
based on the phase-locking value (Lachaux, 1999) rather than
coherence. <br>
Fieldtrip supports the following function, which would be exactly
what I needed:<br>
<br>
cfg=[];<br>
cfg.method = 'plv';<br>
cfg.complex = 'imag';<br>
iplv=ft_connectivityanalysis(cfg,freq);<br>
<br>
However, I did not find any documentation or reference, and was
wondering whether it is feasible to use 'imag' together with 'plv'?<br>
Sadaghiani et al. (2012; J Neurosci) calculated imaginary plv in
their paper like this:<br>

Is this what the ft code effectively does?<br>
<br>
Any help appreciated, thanks a lot!<br>
best, <br>
Tobias<br>
