Activity Cliffs Viewer


Structures and activities of molecules is best viewed in the context of chemical neighbourhood. In the network view, molecules are represented by nodes coloured according to chosen property. A pair of nodes is connected based on an edge similarity cutoff provided in options. The edge is coloured in green if the ratio of activity difference to chemical distance is higher than the "cliff" cutoff set in options.
