Structure Viewer

See your protein the way you think about it

Code2Fold Visualizer is a fast, browser-native molecular viewer. Drop in a PDB or CIF file and explore cartoons, surfaces, and atomic detail — then measure geometry, find pockets, and stage a docking run.

Capabilities

From a raw structure file
to a working hypothesis

Load anything

Open local PDB, CIF and mmCIF files, or fetch directly from the RCSB by ID. Multi-chain and multi-model structures are handled cleanly.

Rich representations

Cartoon, surface, ball-and-stick, ribbon and licorice — colored by chain, secondary structure, b-factor, or hydrophobicity.

Measure geometry

Pick atoms to read off distances, angles, and dihedrals. Inspect H-bonds and contacts around any residue of interest.

Protein preparation

Strip waters, select chains, add hydrogens, and clean a structure so it's ready for downstream simulation or docking.

Pocket detection

Highlight cavities and candidate binding sites, then frame a search box around the pocket you care about.

Docking staging

Define the grid, place a ligand, and hand off to the Code2Fold docking engine — no command-line setup required.

Prepare here, simulate there

Clean a structure in the Visualizer, then send it straight into Studio for a molecular-dynamics run.

Inspect trajectory frames

Load representative frames to see exactly how a binding site rearranges over the simulation.

Export figures

Render high-resolution images of any view for slides, posters, and manuscripts.

One platform

Built to flow into the rest of Code2Fold

The Visualizer isn't a silo. It shares structures, selections, and preparation steps with Studio so your work moves forward without re-doing setup.
