This figure compares the homogeneity of clusters from the protonated lysine dipeptide (a) and the bare lysine uncapped (b) with respect to properties of their elements. The homogeneity of a cluster is probed using the standard deviation with respect to the distance between each cluster elements, \({{\upsigma }}_D\), and the conformational energy, \({{\upsigma }}_E\). The outliers of uncapped lysine (b) were manually highlighted in orange
