HADDOCK: Error in DNA PDB File

Hi, I’m new to HADDOCK and I have been trying to use it to perform some protein-DNA docking, but I keep getting the following error in my DNA file.

Error in PDB file.
Issue when parsing the PDB file at line 1.
Your PDB contains an known residue PDBLine: HETATM 1 P DG A 2 119.420 94.732 30.132 1.00 0.00 P that should be using ATOM record, please check the HADDOCK library for a list of supported modified residues.

Could anyone suggest what should be done to resolve this issue and/or what is causing it?

Thanks.

define your DNA as ATOM and not HETATM in your PDB file

Ok, thank you!
