## About

Molecular Structure Viewer provides a compact Select, Analyze, Compare, Related data, Style, Animate, and Export workbench over Mol*. Use one revisioned atom-level query and scene contract across the UI and Codex to measure geometry, browse source-relative molecular companions, inspect contacts and density, compare aligned structures, style independent layers, play trajectories, restore named scenes and durable digest-bound projects, export provenance-rich results, and render publication images or editable presentation movies.

## Install

1. **Add it in ChatGPT** Open Plugins in the ChatGPT sidebar (web or desktop), search for “Molecular Structure Viewer” and select +. You'll be asked to sign in to any connected service on first use. Then type @ in a chat to call it.

## Disconnect or uninstall

1. **In ChatGPT** Disconnect an account in Settings → Apps or Plugins. To remove the plugin itself, open Molecular Structure Viewer in the Plugin Directory and select Uninstall plugin. Uninstalling can disconnect every account connected through it, and plugins your workspace installs may not offer the option.

2. **In Codex** Run /plugins in the Codex CLI, select the plugin and uninstall it, or press Space to turn it off.

> Runs locally: needs the ChatGPT desktop app or Codex with local execution enabled.

## Skills

- **structure-viewer**: Open, query, analyze, compare, style, animate, and render local molecular structures in Codex's interactive molecular workspace powered by Mol*. Use for PDB, CIF/mmCIF and their gzip/BGZF variants, MOL/SDF/MOL2, PQR/PDBQT, GRO/XYZ, molecular objects, residue exposure, density maps, and topology-plus-trajectory workflows.

## Example prompts

- "Open RCSB 1YCR once; analyze 4 Å MDM2–p53 contacts and buried area, label p53 Phe19/Trp23/Leu26, and report methods."
- "Open RCSB 4AKE once; add 1AKE to the same viewer, align chain A, color teal/magenta, show AP5, and report RMSD/TM-scores."
- "Open RCSB 1EMA once; style and label its chromophore; save a versioned 1600×1200 PNG to structure-viewer/gfp.png with sidecar."
