Hi Shen-Mou,<br>
<br>
<i>Plv</i>pspctrm contains the <i>p</i>hase <i>l</i>ocking <i>v</i>alues,
<i>plv</i>pscptrm<i>sem</i> contains the <i>s</i>tandard <i>e</i>rror
of the <i>m</i>ean of those phase locking values. The variables
without the 'plv' in front of them contain the regular power spectrum. <br>
<br>
Hope it helps,<br>
<br>
Best,<br>
<br>

<pre wrap="">Dear Users,
By setting cfg.cohmethod = 'plv', there are four types of output after running freqdescriptives: powspctrm, powspctrmsem, plvpsctrm and plvspctrmsem. I was wondering which one stands for phase locking values. Many thanks in advance.
