Aten is a tool designed to create, edit, and visualise coordinates. It was written primarily to be of use to people performing simulations of condensed matter, but it may very well be useful to others out there dealing with non-periodic systems.
- Provide a GUI for editing atomic coordinates.
- Create models, even periodic ones, from scratch.
- Randomly add in molecules to periodic boxes, allowing disordered systems to be created.
- Handle several crystal formats, and can replicate and scale unit cells.
