Overview
Molara is an open-source Python package for the 3-dimensional visualization of chemical structures including molecules and crystals. It provides a graphical user interface for importing structures from output files of popular computational chemistry software, as well as for creating custom structures from scratch. The tool is designed to be accessible for researchers and students who need to visualize and analyze molecular and crystalline systems.
Molara supports importing common file formats including .xyz, .coord, and POSCAR files. It can export rendered structures as raster graphics, animate molecular dynamics trajectories, display molecular orbitals from molden files (currently supporting ORCA, Molpro, and TeraChem), and visualize electron densities from cube files. The package is available via PyPI (pip install Molara) and is under active development.
Scientific domain: Molecular visualization, crystal structure visualization
