Subject: AMBER: hold atoms fixed

Hi Amber users

I have performed a minimization on a system composed of two parts and
my point was to held fixed part2 by using the group utility/
Hold part2 fixed
500.0
RES 797 9436
END
END

But after minimization, when I visualised the correspondin pdb i find
that all atoms in part2 has moved as well.
Is there a more specific way to freeze residues? atoms with Amber?
Thanks very much in advance for any help
Regards
Boutheina
