 Enter Cartesian Coordinate File Name :  a.xyz

 Enter Cartesian Coordinate File Name :  a.xyz

 Two Options are Available :  (1) Fit atoms "M" through "N" from structure 1
 to the corresponding atoms of structure 2. Enter "1,M,N" to use this option.
 If "N" is omitted, the fit uses atoms 1 through "M". If both "M" and "N" are
 omitted, the fit uses all atoms; or (2) Individual entry of atom range pairs
 to be used in the fitting procedure.

 Enter an Option (either 1,M,N or 2 [<CR>=1,0,0]) :  1,2,2

 Include Hydrogen Atoms in the Fitting [Y] :  Y

 Use Mass- or Unit-Weighted Coordinates (M or [U]) :  U

 Write Best-Fit Coordinates of 2nd Molecule [N] :  N

 Cutoff Value for Listing RMS Deviations [0.0] :  0.0
