CryoAtlas
A large curated dataset and unified benchmark for cryo-EM atomic model building.
Accepted at NeurIPS 2026 · Evaluations & Datasets Track
Paper (OpenReview) · Code · Project website · 3D Benchmark Explorer
CryoAtlas v1.0 provides 17,809 map–model–sequence entries derived from EMDB and PDB records available up to March 2026: 16,657 training entries and 1,152 test entries, including the 618-target common benchmark. The benchmark evaluates structural accuracy, map agreement and stereochemical quality.

- Entry catalog: search EMD/PDB IDs, resolution and archive links.
- Benchmark results: 618 targets × five methods.
- Training utility: the two released ModelAngelo retraining conditions.
- Example previews: density projections from 10 released examples.
The Viewer uses lightweight tables; maps, structures and sequences are in the archives. The 618 benchmark targets are part of the 1,152-entry test set.
