I was trying to find a way to use the bad channels I retrieved as the second argument but that doesn't work with the EEG input since ARS deletes the channels from that dataset. Also, I will be re-referencing to the mastoids instead of an average reference...does the interpolation line you wrote above still work for that (with the originalEEG.chanlocs) or does this really only work if re-referencing to the average? </p><p class="gmail-p1" style="margin:0px;font-variant-numeric:normal;font-variant-east-asian:normal;font-stretch:normal;line-height:normal;font-family:Courier"><br></p><p class="gmail-p1" style="margin:0px;font-variant-numeric:normal;font-variant-east-asian:normal;font-stretch:normal;line-height:normal;font-family:Courier">Thank you!</p><p class="gmail-p1" style="margin:0px;font-variant-numeric:normal;font-variant-east-asian:normal;font-stretch:normal;line-height:normal;font-family:Courier"><br></p><p class="gmail-p1" style="margin:0px;font-variant-numeric:normal;font-variant-east-asian:normal;font-stretch:normal;line-height:normal;font-family:Courier">Anna</p></div></div><br><div class="gmail_quote"><div dir="ltr">On Tue, Dec 11, 2018 at 6:28 PM David Ryan <<a href="mailto:ryand1@goldmail.etsu.edu">ryand1@goldmail.etsu.edu</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div>This is the script I use.
