XYZ - Water clusters
The water cluster geometries were generated from a large molecular dynamics simulation of bulk water at standard temperature and pressure by including all water molecules within spheres of varying radii.

Molecular dynamics simulation details
Bulk water simulation of 266667 SPC water molecules in a standard cubic PBC simulation box with a side length of 20 nm, which corresponds to a density of 1 g/cm3. The velocity Verlet integrator with a timestep of 1.5 fs was used. A molecular based spherical cutoff of 0.9 nm was employed. The temperature was kept at an average of 300 K using the Berendsen thermostat.
