[Eeglablist] Children's skull thickness

[Robert Oostenveld]

Hi Ryan

I do not know which radii of the multisphere model to use for childrens 
heads, but definitely would be interested if you could come up with 
some good estimates for the skull thickness based on childrens MRIs.

best regards
Robert
