Sorry Tom, I forgot that you need a new mris_smooth as well. I put it on
our ftp site. Use it from the subject's surf directory as follows:

mris_smooth ./?h.orig ./?h.smoothwm

this will also recreate the ?h.area and ?h.curv files, which should work
properly with the new mris_convert (the area should be in mm^2).
