[phenixbb] heavy atom in pdb for refinement

[crystallogrphy]

Hi,
I have Zn atoms in my pdb for refinement. However, it failed with the
following scripts. Do I have to create a libary of this heavy atom?
Number of atoms with unknown nonbonded energy type symbols: 6
    "ATOM      1 Zn    Zn Z   1 .*.    Zn  "
    "ATOM      2 Zn    Zn Z   2 .*.    Zn  "
    "ATOM      3 Zn    Zn Z   3 .*.    Zn  "
    "ATOM      4 Zn    Zn Z   4 .*.    Zn  "
    "ATOM      5 Zn    Zn Z   5 .*.    Zn  "
    "ATOM      6 Zn    Zn Z   6 .*.    Zn  "
  Time building chain proxies: 1.78, per 1000 atoms: 0.45

Here is the format of my pdb:
