[gmx-users] g_h2order

[David L. Bostick]

IN the analysis program g_h2order, what sort of groups should the index
files contain for the arguments -n and -nm ?

My first guess is:

-n -- an index file containing all atoms in water.
-nm -- an index file containing a group of atoms for which the center of
		mass is to be calculated for finding the angle between
		the water dipole and the axis from the center of mass to
		the water oxygen.

Is this correct?  I just want to be sure before I use the program.

Thanks,
David
