Dear Muluh,<br>
<br>
it is not currently possible to limit the plotted region to you
electrode only. To fix that, it would be necessary to find the
intersection of the headplot with a surface (not necessarily planar)
that match the lower part of your electrodes. Once this is done, you
would have to generate 2 surfaces, one for the top of the head and one
for the bottom (and this is tricky because you need to add points so
that the limit is smooth). If anyone is interested to develop that, we
will be glad to include it in EEGLAB.<br>
<br>
For publication purposes, I would simply use the command line option "
'plotmeshonly', 'head' " to get the mesh with skin color and then use a
graphic software to combine your headplot with the skin-colored head
(assuming they have the same view angle.<br>
<br>
I hope this helps,<br>
<br>

<pre wrap="">Dear EEGLAB users,
I will appreciate if anyone can help out on this basic question.
I am
using the headplot function in eeglabv5.02 to plot 3-D maps of my data.
The function plots on the whole head including the neck region (see
attached image). How do I limit the plot to just the section of the head
covered by the 128 electrode net in my case.
Kind regards,
Muluh.
