Hello,
I was able to reproduce the issue. it was an issue on how the unit were named. You can replace the line 123 of the import script from to sDataOut.DisplayUnits =data.oxy.yUnit; to sDataOut.DisplayUnits = strrep(data.oxy.yUnit,'/L','.l-1'); and then reimport the data. You will need to delete the Brainstorm protocol first, I think.
You can then visualize the signal:
One thing you can see however is that we don't have the position of the sensors in this dataset but only the mid-point between each source and detector. This information would be the .SD file mentioned earlier that the author should provide. I guess that with some guessing it would be possible to 'guestimate' some positions but that would be very approximative.
Note: If you right-click on the NIRS channel definition and do 'edit channel file', you can see for each channel, you can get the corresponding EEG name
