1.5 more apparent by looking at number of outliers. Figure shows the ratio of perturbations with absolute errors versus experiment below a certain threshold. Each box illustrates the distribution across the various targets first and third quartiles with the median shown as a horizontal bar inside the box and the whiskers extend up to the minimum (least performing target) and maximum (highest performing target), but at most up to 1.5x(interquartile range) from the box edges (with outliers shown as markers). We observed differences between the force fields in minimum, median and maximum ratios. For a threshold of 1 kcal mol -1 from experiment, the median across targets is at 50% of edges for OpenFF-1.0 and 52% for CGenFF/MATCH*. This median ratio is notably higher for OpenFF-2.0 (57%), GAFF2.1x (60%), OPLS3e (60%) and the Consensus approach (61%). Also the trend of the ratio for the worst performing targets are similar. For the public force fields, the worse performing targets exhibit between 19% and 32% of edges within a 1 kcal mol -1 threshold. For OPLS3e and the Consensus approach this ratio is considerably higher at 44% and 42%, respectively.
