--------------------------------------------
 The MGHTools -> Make Full/Partial Surface Cuts
 menu item starts up tksurfer with a medial view
 of the inflated surface and a default output
 patch name in preparation for making relaxation
 cuts.  But note that any surface or surface
 portion (patch) can be cut, in any view.
--------------------------------------------

--------------------------------------------
CUTS FOR FULL HEMISPHERE FLATTENING
--------------------------------------------
(1) make relaxation cuts:
      ==> RIGHT-CLICK to clear all marks
      ==> LEFT-CLICK sequence
      ==> open-line cut with LINE
            [repeat above]
      ==> one standard 5-cut set:
  cut 1: medial, along fundus calcarine
  cut 2: amygdala to temporal pole
  cut 3: ant. corpus callosum to frontal pole
  cut 4: anterior cingulate to dorsal convexity
  cut 5: posterior cingulate to dorsal convexity
      ==> extend past planned midline removal

(2) encircle midline region to remove:
      ==> RIGHT-CLICK to clear all marks
      ==> LEFT-CLICK sequence

(3) make closed-line cut
      ==> AREA button

(4) seed region(s) to fill/save
      ==> single LEFT-CLICK 

(5) fill seeded region
      ==> FILL button

(6) save patch
      ==> patch: WRITE

The default names for the full cortical surfaces
with the midline removed (following instructions
above) are:

 rh.full.patch.3d
 lh.full.patch.3d

Replace the "full" with some other informative
name for other cuts (don't modify other parts of
the names).

If you want the pose settings for FULL/CORTEX in
the Preferences -> Expert Preferences -> Views
tab to apply to the flattened output, retain
"full" (or "cortex") in the name, but add some
characters (not including '.'), for example:

  rh.full-v1.patch.3d

Be sure that the surface is completely cut apart
at the point where the relaxation cuts end at the
midline cut-out.  To eliminate stray connections,
click on a few vertices on one corner of the cut
and do LINE to remove any stray attachments.
This can be verified with the MESH button (check
for even a single stray edge).

--------------------------------------------
CUTS FOR OCCIPITAL PATCH FLATTENING
--------------------------------------------
(1) make calcarine sulcus relaxation cut:
      ==> RIGHT-CLICK to clear all marks
      ==> LEFT-CLICK sequence
      ==> open-line cut with LINE

(2) specify cutting plane
      ==> RIGHT-CLICK to clear all marks
      ==> 3 LEFT CLICK's
      ==> for a patch including most of visual:
   click 1: medial, splenium corpus callosum
   click 2: lateral, intraparietal
   click 3: lateral, anterior inferotemporal

(3) mark region to keep
      ==> 1 LEFT-CLICK

(4) make the cut
      ==> PLANE button

(5) optional trim around callosum
      ==> RIGHT-CLICK to clear all marks
      ==> LEFT-CLICK sequence
      ==> open-line cut with LINE
            [repeat if necessary]

(6) save patch
      ==> patch: WRITE

The default names for the occipital patches with
a calcarine relaxation cut are:

 rh.occip.patch.3d
 lh.occip.patch.3d

Replace the "occip" with some other informative
name for other cuts (don't modify other parts of
the names).

Be sure to check for stray attachments across
the end of the relaxation cut as above.

TIPS
--------------------------------------------

(1) HOWTO re-do cuts

To re-do a set of cuts using the previous set as
a guide, open the previous cut surface and save a
label.  Then open the original, uncut surface and
display the label with "D" before re-cutting.

(2) HOWTO make complex cuts

To cut a complexly-shaped surface, you may have
to adjust the view.  Upon redraw, the currently
selected set of vertices (previously cyan) will
become white -- but they will remain selected.
Continue selecting vertices, clicking AREA or
LINE when done.

(3) HOWTO make complex closed-line cut in stages

A complex closed-line (AREA) cut can be made as a
series of open-line (LINE) cuts.  In this case,
to avoid stray connections, start each new line
segment by first selecting a vertex on either
side of the end of the last already-cut line.
