<p>Hello,</p>
<p>I juste have a quick question regarding <span>mne.stats.permutation_cluster_test</span>.</p>
<p>When I give it two arrays X1 and X2 of shape (n subjects x n channels x n freq), I have the following error:
<span>ValueError: connectivity (len 20484) must be of the correct size, i.e. be equal to or evenly divide the number of tests (2580984).</span></p>
<p>The error disappear if I reshape X1 and X2 into shape <span>(n subjects x n freq x nchannels).</span></p>
<p><span>I was wondering why because I did not see anything about that in the documentation of <span>permutation_cluster_test</span>.
</span></p>
<p>Thanks in advance!</p>
<p>Kind regards,</p>
<p>Fleur<br>
