What is MolSysViewer?

MolSysViewer is a Python library that lets you control a Mol* 3D scene from Python.

You typically use it in Jupyter. You load a molecular system with MolSysMT, then add overlays and export a shareable view.

What you can do

• Load molecular systems via view.load(...).

• Control visibility, camera, and scene state.

• Apply representations to the whole system or to regions.

• Add overlays (pockets, channels, pharmacophore features, anisotropy, meshes).

• Export lightweight HTML embeds with write_html(..., mode="lite").
