Best practice guide
HADDOCK supports docking of peptides as well. Since the secondary structure of short peptides is not always well defined, is is safer to dock an ensemble of multiple conformations. Different ways of generating of these conformations are described here. More documentation about peptide docking with HADDOCK is in following sections:
