[Pw_forum] Fixing atoms in vc-relax

I am trying to fix some atoms in a vc-relax simulation, i.e., I want the
relative positions of these atoms to remain the same during vc-relaxation.
I specified 0 0 0 next to the atomic positions of these atoms. However
their relative positions do change. I have tried giving the coordinates of
these atoms in both crystal and angstrom units with no luck.
Their relative positions do remain constant in a relax simulation but not
in a vc-relax simulation. Does anyone know what might be the problem?
