PyMOL 3.1.8, released by Schrödinger, Inc. as the tenth consecutive update of its open-source core, is a molecular visualization system designed to render protein, nucleic-acid, and small-molecule structures in publication-quality 3-D. Targeted at structural biologists, medicinal chemists, and educators, the program reads standard PDB, mmCIF, and SDF files, then allows interactive exploration through rotation, slab rendering, surface and cartoon representations, and real-time measurement of distances, angles, and contacts. Researchers use it to prepare figures for journal submissions, generate morphs between conformational states, map electrostatic potential or B-factor coloring onto surfaces, and create ray-traced images that meet editorial standards. Teachers exploit the synchronized command-line and GUI modes to build classroom animations that illustrate drug–receptor docking or antibody–antigen interactions, while bioinformatics pipelines embed the open-source Python API to batch-export hundreds of aligned structures for comparative analyses. The current 3.1.8 release refines GPU-accelerated ray tracing, improves support for 4-K monitors, and maintains backward compatibility with scripts written for earlier versions back to 2.5. The software is available for free on get.nero.com, with downloads provided via trusted Windows package sources (e.g. winget), always delivering the latest version, and supporting batch installation of multiple applications.
