In order to test CrystalNets.jl on a realistic workload, we surveyed the CoRE MOF 2019 database of metal-organic frameworks (version 1.1.3). To do so, we implemented a custom clustering algorithm to regroup atoms into SBUs. Since the definition of MOF SBUs is not universal and IUPAC recommends providing complementary topological descriptions when necessary , we implemented several clustering options to account for different strategies used in the literature.
