Distance restraints
If you specified that passive residues will be defined automatically, all surface residues will be selected within the following radius (in angstroms) around the active residues
Instead of specifying active and passive residues, you can supply a HADDOCK restraints TBL file (ambiguous restraints)
You can supply a HADDOCK restraints TBL file with restraints that will always be enforced (unambiguous restraints)
If one of your molecules is DNA/RNA, restraints are automatically created to preserve its structure.
Uncheck this option if you are docking with unstructured DNA/RNA
Create DNA/RNA restraints?
HADDOCK deletes by default all hydrogens except those bonded to a polar atom (N, O).
Uncheck this option if you have NOEs or other specific restraints to non-polar hydrogens
Remove non-polar hydrogens?
Random patches
Define randomly ambiguous interaction restraints from accessible residues
Center of mass restraints
Define center of mass restraints to enforce contact between the molecules
Force constant for center of mass contact restraints
Surface contact restraints
Define surface contact restraints to enforce contact between the molecules
Force constant for surface contact restraints
Random exclusion
Randomly exclude a fraction of the ambiguous restraints (AIRs)
Number of partitions for random exclusion (%excluded=100/number of partitions)
Sampling parameters
Number of structures for rigid body docking
Number of trials for rigid body minimisation
Sample 180 degrees rotated solutions during rigid body EM
Number of structures for semi-flexible refinement
Sample 180 degrees rotated solutions during semi-flexible SA
Solvent to use for the last iteration
Number of structures for the explicit solvent refinement

Dihedral and hydrogen bond restraints
In addition to distance restraints, you may specify dihedral and hydrogen bond restraints
These restraints can be inter- or intramolecular
