I have a few questions regarding the rejection and interpolation of bad EEG channels. I'm having a similar issue to that of Andrew Hill posted on May 9th, 2011, in that I have a few extremely bad channels that survive the automatic channel rejection function, regardless of the threshold/method applied. </div>

<div style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: 13px; ">The rejected channels are highlighted in red, but channel 55, which is almost comically bad, is not rejected. </div><div style="color: rgb(34, 34, 34); font-family: arial, sans-serif; font-size: 13px; ">

Is there a way to do this in concert with the automatic channel rejection function, and save the bad channels rejected using both methods in one function?</div>
