Sorry to bother with such a trivial question, but I looked everywhere. How and where is the ?h.pial.outer.smoothed surface created?
I understand this surface represents the outer surface of the pial without sulci, similar in shape to the inner surface of the skull.
Thanks, Thomas
Thomas,
?h.pial.outer.smoothed surface is created as a part of the local gyrification index computation and represent the envelope of the brain (hull). It is computed using morphological closing of the sulci (see the validation publication in IEEE TMI and the lGI wiki page).

Thomas,
It's created if you include the -localGI flag with recon-all. You must have matlab installed for this to work. See also:
