1. Delete: Use this option to get rid of an unwanted landmark.

• Delete ENTIRELY? y[n]: Entering "y" deletes all traces (.LMK, .MAP, and references in .SUM), while entering "n" or "Enter" will delete nothing and return you to the Main Menu.

2. Disconnect: This option will remove all overlap and limb information, but will leave all other data intact.
