[Eeglablist] Manually marking bad channels

[Abigail Noyce]

I don't know an easy way to do exactly that, but if you turn on the "colors" option it at least makes it easier to count through them.

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?

If you then ctrl/left-click 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 OK.
