PQViewer is in public beta. File and Python interfaces may change before 1.0.
PQViewer requires Python 3.12 or newer.
The distribution is named MolarVerse-PQViewer; the application, import
package, and command remain PQViewer, pqviewer, and pqviewer.
python -m pip install MolarVerse-PQViewer
pqviewerNode.js is not required. Optional ASE format support is installed with
python -m pip install 'MolarVerse-PQViewer[ase]'.
The CLI also accepts PQ inputs, run directories, ASE sources, and frame slices. See Getting started for examples.
- 3Dmol.js atoms, bonds, protein cartoons, surfaces, cells, and selections
- centred orthorhombic and triclinic cells, wrapping, and molecule reconstruction
- atom and cell editing with EXTXYZ download
- trajectory playback, measurements, analysis, forces, and collision indicators
- independent PNG and TIFF figure rendering with reusable recipes
Search atoms, settings, and commands with the central Search field,
Cmd/Ctrl+K, or /.
python -m pip install 'MolarVerse-PQViewer[jupyter,ase]'from pqviewer import view
viewer = view("trajectory.xyz", height=620)
viewerThe notebook cell embeds the local viewer. Call viewer.close() when finished.
