   This tutorial demonstrates the use of HADDOCK3 for predicting the structure of an antibody-antigen complex using information
   about the hypervariable loops of the antibody and a loose definition of the epitope determined through NMR experiments.

+* [**Haddock3 basic protein-DNA docking tutorial**](/education/HADDOCK3/HADDOCK3-protein-DNA-basic):
+  This tutorial demonstrates the use of Haddock3 for predicting the structure of a protein-DNA complex in which two protein units bind to the double-stranded DNA in a symmetrical manner (reference structure [3CRO](https://www.rcsb.org/structure/3CRO)).
+  In addition to provided ambiguous restraints used to drive the docking, symmetry restraints are also defined to enforce symmetrical binding to the protein.
+  This tutorial is using a local version of Haddock3, and therefore requires the use of a terminal and some basic command line expertise.
