Nope -- you're still the only one. ;-)

You didn't miss any documentation.  General policy is to leave these
cuts alone, unless they run through an area of specific interest.  For
example, The "lobar cuts" coord/topo file in caret tutorial 1 is an
example of an alternate set of cuts that leaves the orbito-frontal area
intact, for those researchers who care only about that area.  This set
of cuts was created by specific request from such researchers.  You are
free to draw your own, or accept the rest of the template cuts (i.e.,
those other than the medial wall and calcarine).

If you can provide a screen capture (preferably in jpg/gif, but ppm,
tif, bmp or other image formats are fine, too), we can get a better idea
of the nature of the distortion.  Also, let us know what files were
toggled on in your spec file options:

	topo
	ref coord
	aux coord
	paint
	surface shape
	border
	metric

One thing that makes a flat map look funny is when you select a closed
topo file with a flat coord file.  That combination will look bizarre
when tile is toggled on.  Also, there typically are multiple options in
the surface shape control, and the map will look different based on
which option is selected.

What were your overlay and underlay selections?

I'm copying John Harwell, since he is the Caret guru.  (I'm the SureFit
guru, and this is the SureFit mailing list, but as you can see,
overposting is not a problem here, and SureFit lives to feed Caret, so I
consider it on-topic.)
