Move_zone [id two atoms] or [mol res1 res2 object]
Moves a specified zone of residues. The user is required to pick an atom in the starting and the ending residue. In particular, double clicking on an atom in a residue makes that residue active and the identified atom is taken as the pivot point. Otherwise the centre of mass is used as the pivot point. The identified zone moves under the influence of the dials. You should use Yes or No to terminate the command. The Clear_flag command accepts the coordinates, producing the same result as Yes. The coordinates of all atoms in the zone are updated as the atoms move but only the displayed atoms are updated on the screen.
