Hi all,

I was trying to check the data quality by checking the target channels. However, it only works for a few channels, i.e., mainly the channels between bottom optodes. When I tried to deselect channels connected to the center optode, Homer3 displayed an error message, as the image shows. 

May I ask if any of you have experienced the problem and how to solve it?

I appreciate any help you can provide.
