# AFDB v6 structure shards and derived data

This repository hosts structural data, annotation tables and saved analysis
outputs used by the GPBridge project. A directory's publication does not imply
that it is a final training release; consult its data manifests and provenance.

Project code, internal reports, experiment material and collaborator handovers
are maintained in the access-controlled repository:
https://github.com/ZhanghanNi/GPBridge

Authorized collaborators should obtain the workflow and instructions there.
Hugging Face is the data store, not the current source of project code.

## Data layout

- `shards/` and `manifest.jsonl`: AFDB v6 Foldcomp structure shards and inventory.
- `annotations/`: saved annotation outputs and mapping tables.
- `results/`, `recovery/`, `enzymm/`: saved retrieval results and derived tables.
- `alphafill/`, `ligands/`: coordinate contexts and source provenance.

The original Foldcomp collection comprises 241,070,489 records in 483 shards.
This is the source collection's coverage, not the nominal size of all AFDB.
Derived collections have their own scopes and manifests.
