<font face="Georgia">Hi Fieldtrippers,<br>
<br>
I am interested in analyzing PLV or coherence in my MEG data from
a Neuromag 306 system. In the past, for looking at power alone, I
have calculated TFRs on the gradiometer data, then ran
ft_combineplanar to average the gradiometer pairs. Should I use
the same approach for calculating the cross-spectral density, or
does this create any problems when I go to combine the results for
gradiometer pairs? In particular, I am trying to wrap my head
around how I would set up cfg.channelcmb if I want to look at all
channel pairs, but then want to subsequently perform
ft_combineplanar. (or maybe this is the wrong approach
altogether?)<br>
<br>
Thanks,<br>
David<br>
<br>
