<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">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>
