<div dir="ltr">Hi Dave,<div><br></div><div>no all is computed across trials. When using a continuous Morlet Wavelet the cross-spectral density matrix is time-resolved but the same metrics can be computed. You always consume the trials dimensions in both case, irrespective of the connectivity metric.</div><div><br></div><div>Hope that helps,</div><div>Denis</div></div><br><div class="gmail_quote"><div dir="ltr">On Wed, Apr 12, 2017 at 4:15 PM David I Leitman <<a href="mailto:leitman@mail.med.upenn.edu">leitman@mail.med.upenn.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word" class="gmail_msg"><div dir="auto" style="word-wrap:break-word" class="gmail_msg">Hi Dennis,<div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg"> I don’t mean to bud in, but a quick question</div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">are both of these examples</div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg"><a href="http://www.martinos.org/mne/stable/auto_examples/connectivity/plot_mne_inverse_connectivity_spectrum.html#sphx-glr-auto-examples-connectivity-plot-mne-inverse-connectivity-spectrum-py" class="gmail_msg" target="_blank">http://www.martinos.org/mne/stable/auto_examples/connectivity/plot_mne_inverse_connectivity_spectrum.html#sphx-glr-auto-examples-connectivity-plot-mne-inverse-connectivity-spectrum-py</a></div><div class="gmail_msg"><a href="http://www.martinos.org/mne/stable/auto_examples/connectivity/plot_cwt_sensor_connectivity.html#sphx-glr-auto-examples-connectivity-plot-cwt-sensor-connectivity-py" class="gmail_msg" target="_blank">http://www.martinos.org/mne/stable/auto_examples/connectivity/plot_cwt_sensor_connectivity.html#sphx-glr-auto-examples-connectivity-plot-cwt-sensor-connectivity-py</a></div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">calculating phase connectivity across trials that is- wPLI is calculated from the phase angle difference distributions at a particular point across trials</div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">or is one or both often calculating phase angle differences from multiple points across the time from within each trial that is wPLI across time? </div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">thanks //dave</div></div></div><div style="word-wrap:break-word" class="gmail_msg"><div dir="auto" style="word-wrap:break-word" class="gmail_msg"><div class="gmail_msg"><br class="gmail_msg"><blockquote type="cite" class="gmail_msg">
