<p class="MsoNormal" style="text-align:justify"><span lang="EN-US" style="font-family:Arial,sans-serif">I would like
to perform a cluster-based permutation test on weighted phase lag index values by
using a within-subjects experimental design. I have two conditions (congruent
and incongruent one) and my goal is to compute WPLI between certain channel
combinations (FCz and F3 for instance) and see the WPLI change let’s say in 3-9
Hz and -100 to 500 ms between the two conditions. </span></p>

However, if I use it for WPLI data, I have the following error: “This function
