Move_fragment [id an atom] or [mol res1 res2 object]
Moves an atomic fragment. The fragment containing the identified atom moves, with this atom as the pivot point. The breakdown of each residue into fragments is defined in a dictionary, and can be customized by the user. Currently, the dictionary is the same as that used by the RSR menus. In the distribution files, the peptide plane fragment is defined as CA C O N+ (i.e. the nitrogen of the next residue). Do not therefore, identify a peptide nitrogen to define the fragment. 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 are updated as the fragment moves.
