There are two multi-chain protein in my example,when i define the restraints to pull together the chains in one protein and save as unambig.tbl feeded to HADDOCK,but it fails. It stopped at the it0.I think there may be some problem about my restraints, because the segid is not filled and the procedure and correctly recognize the bodies restraints?
Unclear to me what you are exactly doing / trying to do.
Segids should indeed be present.
Are you running a local version of HADDOCK. Make sure your input PDBs have chain/segids before generating the bodies restraints
