[phenixbb] heavy atoms

[ChenTiantian]

Hi,
I am dealing with a complex structure which the ligand contains a atom
Iodine, I guess it's because Iodine is heavy atom,
the electron density of Iodine turns red after 5 cycles refinement.
Anybody coped with similar issue?
How to let phenix know that the Iodine atom is part of the ligand?

Best,
Tiantian
