 Medit -- display and edit MRI slice data
------------------------------------------------
Medit reads one or more series of images and
displays them in coronal, sagittal, horizontal,
or all 3 planes.  The images in the first (edit)
buffer can be edited and saved.  Images read into
the second buffer cannot be edited.  Edits
applied while viewing the second buffer affect
the first buffer (useful when edit buffer has
segmented white matter and second buffer has
original full T1 images).

Medit can also read in a surface and display the
intersection of the surface with the current
slice.

Display Parameters

The currently selected pixel value is displayed
in the window title bar.  The default settings for
"contrast" (12.0) and "midpoint" (0.35) increase
contrast between gray and white matter in images
normalized using mri_normalize.

The "maximum" button displays the brightest pixel
along each line extending perpendicular to the
current slice plane.

Extended Interface

Several levels of interface are available by
typing the following commands while in the
interface window:

ctrl-F1   micro (minimal editing)
ctrl-F2   mini  (default)
ctrl-F3   mini+ (add manual piecewise lin norm)
ctrl-F4   macro (curv,fieldsign display, EEG/MEG)

Standalone Operation

Tkmedit can also be run as a standalone program
from anywhere in the directory tree from the
command line:

Use: tkmedit name imgdir [surf] [-] [-tcl script]
     tkmedit local [-] [-tcl script]

  name: subjectdir name         (in $SUBJECTS_DIR)
imgdir: orig,T1,brain,wm,filled (in $subject/mri)
  surf: e.g., rh.smoothwm       (in $subject/surf)
  dash: disable editing
