<div dir="ltr"><div>Thanks Makoto. My data was while participant walking on treadmill, for some reason 'clean_rawdata' didn't work. I tried other dataset where participant was sitting in a chair. Your method worked great. It removed 5 channels from the data. Do you interpolate the removed channels?<br>

Please try 'clean_rawdata()'. It has a flat channel removal function.</div>

Flat lines have limited variable data. So you can try:<br>
<br> devStd = std(EEG.data(:,:), [], 2);<br> if any(devStd == 0)<br> flatchan = find(devStd == 0)';<br>
