Then, we extracted the top 50 MOFs from each ranking, consistent with the philosophy of previous screening studies which typically seek to narrow the candidate list to only the top performers. We find that the material rankings are poorly-to-moderately positively Let us first focus on the comparison between UFF and Dreiding in Figure , with each of these LJ parameter sets combined with the DDEC charges. We see that 35 MOFs are shared in the list of top performers between these two variants of the forcefields. Turning now to the combinations of UFF with other charge schemes, the greatest level of agreement is between DDEC and Qeq, with 36 MOFs appearing in both lists of the top 50 materials. It is also quite apparent that the EQeq charges provide a much poorer level of agreement, with only 27 MOFs appearing in the ranking obtained using the DDEC charges. We find that even if we take a different molecular FF as the baseline (Figure ) or focus on a shorter list of candidate materials, i.e., the top 20 (Figure ), that generally: (1) there is consistently Finally, we have some materials with such a strong volatility in their process KPIs that they may fall far below the top 50 threshold, depending on the choice of FF. These constitute the largest proportion of materials, and in many instances the difference in performance is sufficient to classify the same material as suitable (in other words, meeting the CCS constraints) by one FF and not suitable by another FF. Note that these trends persist when the other FFs are taken as the baseline for comparison (Figure ).
