I am still running into bugs when doing the freq_time clustering. I am testing for coherence between the hemispheres during a task, and now it runs into problems at clusterstat() at line 175. The command is:<br><br>posclusobs = findcluster(reshape(postailobs,<br>
[cfg.dim,1]),channeighbstructmat,cfg.minnbchan);<br><br>The problem is that postailobs has size [nfreq*ntime, 1], while the cfg.dim is [nchan nfreq ntime], where nchan=2 in this case. It seems like it wants to reshape it into size [nfreq, ntime, 1]. Is this indeed the case?<br>
<br>And could someone help me out by explaining a bit more about when one would choose for cfg.clusterthreshold the different values, 'nonparametric_common', 'nonparametric_individual', and 'parametric' when testing for coherence in different brain areas? I have read over the documentation and the code but am still somewhat unsure.<br>
<br>Thank you for the help,<br>-chetan<br><br><div class="gmail_quote">On Thu, Mar 4, 2010 at 6:13 AM, Andrea Ostendorf <span dir="ltr"><<a href="mailto:aostendorf@besa.de">aostendorf@besa.de</a>></span> wrote:<br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
Dear Roemer,<br>
<br>
thanks. Yes, this helps.<br>

</div>Sorry, I just meant that I have to specify the channels which I want to send<br>
to ft_freqstatistics.<br>
