   • Some ligand is (possibly) present, but location is not well known
   • A ligand is (possibly) present, and the location is well known
   • A ligand is (possibly) present, and the location is well known: variation
   • Some settings that might need adjustment

6. Advanced features
   • The .autoBUSTER system of files and advanced command-line syntax
