<div dir="ltr">Hi Laura,<div><br></div><div>Just a guess. You want to replace some bad channel by interpolating it. If this is true, I think it's not correct to remove them prior to interpolation, or you'll interpolate another channel instead, and if the channel to remove is the last channel, it would encounter dimension errors similar to the one you showed. So, you may need to remove 'pop_select' command from your code.</div><div><br></div><div>Best,</div><div>Chao</div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><font size="2" face="arial, helvetica, sans-serif">Chao Wang, PhD Candidate</font><div><font size="2" face="arial, helvetica, sans-serif">Institute of Biomedical Engineering<br>Xi'an Jiaotong University<br>No.28, Xianning West Road, Xi'an, P.R.
