Wat2ions

Wat2ions is complementary to DelPhi, the renowned solver of the Poisson-Boltzmann equation. The electrostatic potential map pre-computed by DelPhi is used to replace a certain number of the water molecules of the bath, surrounding a solvated macromolecule, with ions. The potential on the oxygens of the water molecules is estimated using a 3D cubic spline interpolation of the pre-computed potential. The waters with the largest potential are replaced with chlorides, and the waters with the smallest potential, with sodii. No two ions are placed closer than a certain distance to each other. The coordinates of the macromolecule, the water bath (except the replaced waters), and the placed ions are output to a new PDB file.
