I'm new to freesurfer, so I'm hoping this question isn't too
obvious. I've searched the mailing list archives and the wiki but
haven't found any leads.
I'm wondering if there's a way to generate a volume representation of
the cortical sheet, based on the data from the white surface and the
pial surface, so that the sheet will be guaranteed to have good
topology, as well as retaining the proper thickness at each point?
It seems like all the information for this is there already since we
have the two surfaces, but I don't know how to go about figuring out
how to convert it into volume data.
Here's a small image that might help give an idea of what I need:

In case you're curious, the reason I want this is because we're
trying to test the novel method for cortical thickness measurement
given in "Three-Dimensional Mapping of Cortical Thickness Using
Laplace's Equation", Jones, Buchbinder and Aharon, Human Brain
Mapping 11:12-32(2000).
