We present a new concept in FlexX that determines torsion angles for OH-groups on the receptor side. For the affected amino acids SER, THR, and TYR, hydrogen bonds to neighbouring residues and the ligand are taken into account, providing a more realistic representation of the binding site. This is done irrespective of the ligand type, and without the user's interaction.

We present the concept itself as well as some case studies as early proof-of-concept.
