<p>Is there a way to highlight a channel from the 'stacked' view of the channels? So that when I view the channels in the 'stacked' view and there is a clear outlier I can select that and know which channel to remove? For example, in the attached, what is the
easiest way to find out the number of the channel with the much larger waveform?</p>

Hi Katherine,<br>
<br>
At the bottom of the EEGLab <font face="Courier New">Edit</font> menu there is an option for "visual edit...". This will open the eegplot figure with a couple extra capabilities. If you then
<font face="Courier New">ctrl/left-click</font> on the eegplot figure a GUI will pop up allowing you to flag the channel (or edit events). simply select the "toggle bad channel status" and then press
<font face="Courier New">OK</font>.<br>
<br>
This functionality is not yet fully integrated into EEGLab (although I am almost finish testing an integrated prototype) and it simply edits a
<font face="Courier New">badchan</font> field in the <font face="Courier New">EEG.chanlocs</font> structure. There are no GUI options yet for handling these flags, but from the command line you can use:<br>
<br>
<font face="Courier New">EEG = eeg_interp(EEG,find([EEG.chanlocs.badchan]),'spherical');<br>
EEG = eeg_checkset( EEG );<br>
</font><br>
to interpolate the flagged channels,<br>
<br>
or:<br>
<br>
<font face="Courier New">EEG = pop_select( EEG,'nochannel',{EEG.chanlocs(find([EEG.chanlocs.badchan])).labels});<br>
EEG = eeg_checkset( EEG );<br>
</font><br>
<div>to remove the flagged channels.<br>

<p>Is there a way to select channels for rejection (for example, when using pop_eegplot)? I have been using pop_rejchan to automatically mark channels and reject them that way, but is there a way to manually mark for rejection based on visual inspection, as
can be done with epochs?</p>
<p> </p>
<p>Thanks for your help,</p>
