For the structures for which the underlying net has been recognised as one of the IZA-SC, there is little doubt on the validity of the detected net. For the others however, there is no systematic way of determining whether the detected net is indeed that representing the structure or not except from visually checking the adequate superposition of the detected net and the initial framework for each file. This limitation comes from the lack of cleaning of the input CIF files, which can lead CrystalNets.jl to interpret solvent residues as part of the framework for instance, or duplicate atoms as two different atoms instead of one. This issue can be circumvented by either cleaning the CIF inputs, as in the CoRE MOF database, or by manually checking the correspondence if working on individual files. Obviously, this limitation is inherent to the quality of the input files and affects all topology determination codes.
