[FieldTrip] Regarding Tutorial: Preprocessing and averaging of multi-channel NIRS data

[Sunny p]

Hello Jorn,

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
http://www.fieldtriptoolbox.org/tutorial/nirs_multichannel#epoch (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.

Thanks for your understanding and support.

Best Regards,
Sunny
