I know the possibitity how to do it in G98 - in input file after the atom name which shoul be frozen, you have to write value -1 and next give the cartesian cooridinates of the atom. However it does not work in G94. Does anybody know how to do it in G94 version? I known that I can froze some geometrical parametrs (torsion angles etc.) but I prefer rather fixing the atom position on its nuclei. Thank You very much for any suggestions.
