The attribute 'map_to_surf' will map your results to the gray matter
central surface and not give you the normal component of the E field.
What you want to do might be a little post-processing. I do not know
which language you use for your development, but in python you can
simply do the following, for example, if you have a mesh in FsAverage
field_name = 'E_normal'
You can find more details here:
It also has a Matlab example for the same purpose. Good luck. And please
let us know if you have further questions.
