Hi Prof Walker,
Thanks for quick reply.
I tried to restainting group with restraintmask and dipole printing with
defining group in &dipoles namelist.
But it seems that when restraintmask is defined program doesn't try to
read any other group information fron input file. as I tried to define
different groups for dipole printing,I got same dipole moments.
