Box-like plot of the ASFE results for groups
of molecules sharing
the same chemical functionality; results are only shown when there
are at least 10 molecules belonging to a group in the database. The
classification into functional groups follows the original work by
Mobley and Guthrie.23 Left: the absolute
error compared to the experiment, obtained with transformato/CGenFF (blue, this work) and GAFF23 (orange)
are shown in a box plot-like manner. For each calculated ASFE, the
absolute deviation from its experimental value is calculated, grouped
and assigned to the corresponding functional group. The black crosses
indicate the mean absolute error (MAE) for a particular group. The
whiskers indicate the molecules with minimal and maximal deviation
from the experimental ASFE. The bars depict the range from the first
to the third quantile of the MAE values. The median absolute error
is indicated as a thin, dashed vertical line. Right: the gray bars
indicate the number of molecules belonging to a group.
