The Markers Menu
The left mouse button controls the creation and manipulation of

When a marker type of selected, new markers of that type can be
created using the left mouse button. The current default marker type

box is displayed for text entry and a text marker is put up automatically.
This same functionality is available using T in the image window.)

for more information about the region name/color mapping scheme.

The regions displayed in the current frame are saved (zoom 1 coordinates).

See Changing Region Names for more
information about region names and colors.

lines. A new line can be added with ^M. You can edit each line or
add new lines. The available colors are the same ones displayed in
the "Set Default Marker Color" menu option.
When you click OK, the association is updated and new regions will
use the new association. Use either of the next 2 menu options to
update the current regions.

purple, yellow, blue, magenta, green, white, black, darkslategray, cyan,

if that name is in the current list of name/color associations.

fix params defined already).
See Fixing/Freeing Regions for
more information.
- Edit Global Fix Params For New Markers
Modify the state of the global fix params. A dialog
box is displayed that contains the current state of
these params. Edit the values in the dialog box, and
press [Return] to commit changes.
See Fixing/Freeing Regions for
more information.
- Fix Current Markers Using Global Fix Parameters
