I submitted PDB structures via HADDOCK Server 2.4, which contain iodine, e.g.:
HETATM 2656 I IOD A 311 21.537 36.399 1.691 0.50 28.73 I1-
However, the server shows the following error:
The following error occurred when processing one of your PDB file: Unable to generate topology for ligand IOD. PRODRG did not create the required output
Standalone version also complains on missing IOD in topology.
Thanks for your help!
