<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Dear Fieltrippers,
<div><br>
</div>
<div>After running ft_connectivityanalysis on a subset of pre-processed resting-state EEG data the dimord is still listed as chan_freq_time (where the first dimension is simply all the pairwise channel comparisons). If I want to run subsequent network analysis
on this the ft_networkanalysis require a chan_chan_freq_time matrix. Is there any way to convert this so that I can run the network analysis or am I missing a setting in the connectivity analysis that would give me that output?</div>
<div><br>
</div>
<div>This is the code I used (my entire resting-state recording has been replaced into 4 second segments in order to get 'trials' for the WPLI connectivity function:</div>
