Hi,
I'm trying to flatten a portion of macaque visual cortex that I
reconstructed from histological sections using Caret5.3, and I ran into a
similar problem as Rishi. After cleaning-up and cutting my surface, I
selected Surface | Flatten Full or Partial Hemisphere, Partial Hemisphere
(Fiducial), and received the following error message: "There is no geography
paint column which is needed for flattening the partial hemisphere. The
geography paint column contains the 'CUT.FACE' nodes which are needed to
properly orient the partial hemisphere for flattening".
It may be relevant that when I tried using Surface | Cuts | Draw Cuts to cut
my surface as described in Tutorial 9, Caret retained only three or four
distantly-spaced points and gave a rough, straight-line approximation of the
cut I drew. To get better precision, I ended up cutting my surface by
manually deleting links, instead.
I was hoping you could tell me how to create the necessary cut face
information to flatten my surface, and also what might have gone wrong with
the Surface Cuts feature (i.e. why I couldn't get it to follow a irregularly
shaped cuts as in the tutorial). I am uploading my files, in case they will
help. Thanks,
