To more rigorously assess the assembly performance across a range of different parameters, we selected a central point in "parameter space" and examined a series of perturbations along individual parameters. For each set of parameters, a set of 10 assembly simulations was performed for each of the targets in Figure . The quality of the assembly simulations was assessed using the minimum value of the loss per particle obtained during the assembly trajectory. Figure shows a , where the radius of each particle roughly corresponds to its σ value and the color shows its charge (q), with blue being positive, red being negative and white being neutral. The target structures show the conformers that were used to generate the target set of features that are almost indistinguishable from the 125 ps structures in each case.
