[Eeglablist] Flat data in a continuous EEG & Linear Regression

[Jerry Zhu]

Hi Srinivas,

Flat lines have limited variable data. So you can try:

    devStd = std(EEG.data(:,:), [], 2);
    if any(devStd == 0)
        flatchan = find(devStd == 0)';
   end

If you need complete codes, feel free to email me.

Good luck with your study!
Jerry

We have two halves in the brain: left and right. Nothing is right in the
left. Nothing is left in the right.
