Hi Vera,
<div><br>
</div>
<div>In your experimental setup there is no repetition of events, time-locked to which it makes sense to compute TFRs. I would expect that your scientific question does not assume that there is a fine-grained modulation of the mu rhythm over time
within the individual conditions that you sketched in your earlier e-mail. Therefore, you might consider integrate across as much time as possible, i.e. the 1 minute per condition of interest.</div>
<div><br>
</div>
<div>Best wishes,</div>
<div>Jan-Mathijs</div>

<div>Dear Vera,
<div><br>
</div>
<div>Perhaps you might find it helpful to start reading the following:</div>
<div><br>
</div>
<div><a href="https://www.fieldtriptoolbox.org/walkthrough/" target="_blank">https://www.fieldtriptoolbox.org/walkthrough/</a></div>
<div><br>
</div>
<div>This is a basic explanation of experimental data analysis works in general, focussing on how it’s done in Fieldtrip.</div>
<div><br>
</div>
<div>Also, you could have a look at:</div>
<div><br>
</div>
<div><a href="https://www.fieldtriptoolbox.org/tutorial/coherence/" target="_blank">https://www.fieldtriptoolbox.org/tutorial/coherence/</a></div>
<div><br>
</div>
<div>Which explains how to extract a neural metric (in this case: coherence) from an experimental set up that is similar to yours. Obviously, you’d need to abstract away quite a bit from this tutorial but it might contain some useful pointers.</div>
<div><br>
</div>
<div>Good luck,</div>
<div><br>

<div>Hello,</div>
<div>I have some EEG EPOC+/Flex acquisitions that are organized as follows:</div>
<div>- 1 min rest->1 min ME RH->1 min ME LH->1 min MI RH->1 min MI LH, considering for ME motor execution and for MI motor imagination.</div>
<div>The total duration of acquisition is 5 minutes. During the condition of motor execution and imagination the subject performed or imagined the related movement for 1 minute.</div>
<div>I need to evaluate the differences in mu rhythm between the five conditions.</div>
<div>Any suggestions on how to perform the analysis?</div>
<div>Thanks</div>
