Hi Jack,
<div><br>
</div>
<div>No, currently it is not possible to cluster data of dimensionality chan_chan_<something else>_<etc>. In older versions of the low-level code (findcluster) there were some lines of code (experimental) which have never been ‘active’ as such - i.e.
they were not reachable when these functions were called from the higher level code. In the old days, if I remember well, Eric played around with channel-like clustering along more than one dimension, but the active development of this functionality was abandoned
because it was hard to get it right. I have just finished a revision of the clustering code which will be released soon, where I actually haver removed those non-functional lines. </div>

<div>Best wishes,</div>

Is there an established approach to clustering across channel x channel x frequency, as mentioned in this thread? I am hoping to try an exploratory between groups analysis of WPLI differences and it is unclear if the current fieldtrip functions behave when
dealing with that complexity.<u></u><u></u></div>

The ‘findcluster’ function seems well set up for matrices of chan x freq x time, but it is difficult to determine if it can handle chan x chan x freq appropriately, or if a new function is required altogether.<u></u><u></u></div>
