[Chimera-users] Changing chain ID for ligands

[Elaine Meng]

Hi Ahmad,
The Change Chain IDs tool (in menu under Tools… Structure Editing) or “changechains” command changes the chain ID of all kinds of atoms, including ligand and solvent.  For example, if you change the ID of chain A to chain F instead, the ligand and solvent atoms of chain A will become ligand and solvent atoms of chain F.

However, if you mean you want to change  ONLY the ligand chain ID without changing the ID of other atoms in the same chain (only change the ID of part of a chain), there is no tool do that in Chimera.  You could just text-edit the ligand atom lines in the PDB file using your favorite text editor.

I hope this helps,
Elaine
