= mri_pretess =

Changes white matter (WM) segmentation so that the neighbors of
all voxels labeled as WM have a face in common - no edges or
corners allowed.

=== Usage: ===
{{{
mri_pretess [options] filledvol labelstring normvol newfilledvol
}}}

=== Options: ===
{{{
 -debug_voxel C R S
 -nocorners : no removal of corner configurations in addition to edge ones
 -w : turn on diagnostic writing
 -keep : keep WM edits
 -test : adds a voxel that should be removed by mri_pretess.
  The value of the voxel is set to that of an ON-edited WM,
  so it should be kept with -keep. The output will NOT be saved.
}}}

=== Required: ===
{{{
  filledvol    is usually wm.mgz
  labelstring  is usually wm (127 for rh, 255 for lh)
  normvol      is usually norm.mgz
  newfilledvol is usually wm.mgz
