This script was written with Materials Studio 4.4 version. It requires only MS Materials Visualizer. The script reads a 35A radius nanosphere and empties the inside of the sphere leaving a 30A thick hollow sphere. The initial sphere can be generated using, for example, the ZnS.xsd structure from Materials Studio templates and then using nanostructure builder the 35A nanosphere can be built. The initial structure file can not be provided due to its big size.
