In response, we removed CSD entries that can not be uniquely matched with a NIST-ISODB adsorbent as well as entries with overlapping atoms. This operation was done manually, and the exclusions are tracked in the GitHub repository associated to this project. Finally, we compared the SGH of all structures once more, but with a different purpose: to identify cases where the SGH of two CSD structure was the same but the name was different. For example, only experienced scientists in the MOF field are likely to recognize MAF-4 as a synonym for ZIF-8.: this analysis allowed us to add this new synonym to the NIST-ISODB adsorbent definition.
