NAME
     MeanMol - create mean molecule

SYNOPSIS
     MeanMol name
	 ( avg_bfactor | max_disp | rms_disp | x_ray )
	 ( mean_only | set_all )

DESCRIPTION
     Create a new molecule with the given name. The new
     molecule will be the mean structure of all selected
     molecules. At least one molecule must be selected,
     and all selected molecules must have the same
     structure.

     The second argument determines how the B-factors
     of the new molecule are set:

	 avg_bfactor: average value of all B-factors

	 max_disp: maximal displacement from mean
	     structure

	 rms_disp: root mean square of all displacements

	 x_ray: values corresponding to B-factors used
	     for X-ray structures (mean square displacement
	     multiplied by 8/3 * pi * pi)

     If the third argument is mean_only, this B-factors
     are only set in the new mean structure, if it is
     set_all, the B-factors of all selected structures are
     set to this value.

     The newly created molecule will have the property
     "mean".
