The AutoDock Vina search space sizes are given in Angstroms instead. If you really intended to use an unusually large search space, you can ignore this warning, but note that the search algorithm’s job may be harder.

The radius of an atom can only be found by measuring the distance between the nuclei of two touching atoms, and then halving that distance. As you can see from the diagrams, the same atom could be found to have a different radius depending on what was around it.

WebThe van der Waals radius, r w, of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom.
