[Eeglablist] Headplot Question

[arno]

Dear Muluh,

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.

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.

I hope this helps,

Arno
