We seek to quantify the level of agreement between FFs at the molecular and process simulation levels. To do so, we make use of a number of statistical metrics which are both local, i.e., relating to a single material, and global, i.e., relating to the entire CRAFTED-u MOF database. Let us first focus on molecular simulations, used to generate equilibrium adsorption data. In addition to the comparison of individual adsorption isotherms generated from different FFs, we also employ the Spearman correlation coefficient, 𝜌, to measure the global extent of the correlation between adsorbate uptakes predicted by different FFs. Perfect positive correlations result in 𝜌 = 1, perfect negative correlations in 𝜌 = -1, and no correlation in 𝜌 = 0.
