Hi, 

     I want to do a relaxation calculation of a 32

  atom cell by keeping one atom at a fixed position and other 31 atoms to be
relaxed.Is it possible to do the problem by setting X-iforce,Y-iforce and
Z-iforce equals to 1 for 31 atoms and by not setting for the atom I want to be
fixed ? Or, there is some other procedures for doing the job? Please help.
