CryoAtlas v1.0 — Test Set

The complete CryoAtlas test set contains 1,152 EMD entries. Each entry includes an experimental cryo-EM density map, corresponding atomic structure file(s), and protein sequences.

The data are provided in two archives:

- CryoAtlas_v1.0_test_benchmark_618.tar.gz
  Contains the 618-target common benchmark used for cross-method comparison in the paper. This subset was obtained after training-overlap filtering and selecting targets with valid outputs from all evaluated learning-based methods.

- CryoAtlas_v1.0_test_remaining_534.tar.gz
  Contains the other 534 entries from the complete test split. These entries remain available for broader evaluation and future method development.

The 618 targets are included within the 1,152-entry test set. The two archives contain no overlapping EMD entries; together, they reconstruct the complete test set. The remaining 534 entries should not be interpreted as a collection of failed predictions, because benchmark membership also depends on eligibility filtering.

Each archive can be extracted independently. Extract both into the same directory to obtain all 1,152 entries under CryoAtlas_v1.0/test/.

In the Hugging Face repository, resources/metadata/test/ provides subset-specific EMD lists and file inventories; resources/metadata/checksums/test/ provides archive SHA-256 sidecars. See resources/docs/downloads.md for verification commands. Original map, CIF, and FASTA contents are preserved.
