<p class="MsoNormal">The usage is 100% equivalent to standard FieldTrip conventions, so you can follow any tutorial on the FieldTrip wiki and try it with your NIRS data (but keep the fundamental difference between EEG and fNIRS in mind). I hope this helps
to get started!</p>

<p class="MsoNormal">Hi Sunny,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">The ADC channels in the tutorial are used as a trigger-channel. I am not sure how you insert the triggers in your experiment, but the Octamon has no direct trigger input (you could add triggers either wirelessly using a PortaSync or directly
from within Oxysoft). The ADC of the Octamon is the battery level and not a trigger input. Depending on what you did, you have to follow different processing steps. If you let me know more about the events and triggers, I can let you know what to do (you could
also send me some example data and I will send you an example script back that reads in the data in FieldTrip).</p>

<p class="MsoNormal">Hello Jorn,</p>
<div>
<p class="MsoNormal"> </p>
</div>
<div>
<p class="MsoNormal">Thanks a lot for your response. I am working with Octamon data (4*2 Channel). I am trying to visualize the data using topo plot on head based image following <a href="http://www.fieldtriptoolbox.org/tutorial/nirs_multichannel#epoch">http://www.fieldtriptoolbox.org/tutorial/nirs_multichannel#epoch</a>
(nirs multi channel tutorial based on Oxymon which has 48 channel). I am wondering what parameter changes should I make to get the data for OCTAMON visualization as my data has only ADC001 and there is no ADC002 in data for epoch section. As I am not an NIRS
expert, its difficult to figure out which parameters gives me the visualization as its throwing errors when following the tutorial.</p>
