> Does fieldtrip allow us to produce clusters on a 3D matrix (TIME X FREQ X<br>> CHANNEL) while shuffling between/within subjects/groups? Or one should go<br>> about doing Time and Freq permutation separately (2D clusters at one<br>
> specific frequency (or time))?<br>><br>> Many thanks in advance,<br>><br>> Regards,<br>><br>> Faranak<br>> -------------- next part --------------<br>> An HTML attachment was scrubbed...<br>> URL: <<a href="http://mailman.science.ru.nl/pipermail/fieldtrip/attachments/20131128/e67e370e/attachment-0001.html">http://mailman.science.ru.nl/pipermail/fieldtrip/attachments/20131128/e67e370e/attachment-0001.html</a>><br>
