[Eeglablist] Inquiry for Code to Create Visually Appealing Graphics that Show ROI Locations

[Olivia Yang]

Hi experts,

Could you please help me understand why the head model always goes out of bounds (see the picture) when I try to plot the positions of a few electrodes using the following code:

topoplot([ ],Channellocation,'plotchans',[37 38 39],'style','blank','electrodes','on','numcontour' ,0, 'emarker' ,{'.','k',21,1}, 'whitebk','on','hcolor','k' );

Also, I was wondering how I could plot these three electrodes in two colors. I know that 'emarker2' option can be used when there are values, but the function prompts me that this option cannot be used when there are no values.

Thank you in advance for your help.

Olivia
