# Embpy Static Embeddings
This dataset contains static gene and protein embeddings packaged with embpy. Embedding values are stored in Zarr arrays, while row identifiers, provenance, species metadata, and AnnData-like `.uns` metadata are stored in sidecar metadata files.
## Summary

- Number of embeddings: `11`
- Total indexed entities: `201,717`
- Species keys: `human_9606`
- NCBI taxonomy IDs: `9606`
- Default gene identifier policy: `ensembl_id`
- Unresolved gene identifier policy: `drop`

## File Layout
```text
manifest.json
embeddings/<model_key>/
values.zarr/
metadata/
index.parquet
index.csv
metadata.json
uns.json
```
The dense matrix is stored under `values.zarr`. The `metadata/index.parquet` file maps row positions to `entity_id` values and any preserved aliases such as source IDs or gene symbols.
## Loading With embpy
```python
from embpy.pp import HFHandler
hf = HFHandler("theislab/Embpy_Data")
embedding = hf.download_embedding("crispr_gene_effect")
matrix = embedding["embeddings"]
ids = embedding["ids"]
```
For a local checkout or downloaded snapshot:
```python
from embpy import load_static_embedding_package
store = load_static_embedding_package("/path/to/package", key="crispr_gene_effect")
tp53 = store.get("ENSG00000141510")
tp53_by_symbol = store.get("TP53", id_type="symbol")
```
Missing identifiers raise by default. Use `missing="drop"` or `missing="nan"` when a partial result is acceptable.
## Metadata And Species
This card reports species using package-level defaults. Regenerate the package with a current embpy build to also write per-embedding `species`, `taxonomy_id`, and `species_key` fields into `metadata/metadata.json`.
## Validation
The package was designed to be validated locally before upload:
```bash
python -m embpy.scripts.package_static_embeddings validate --package /path/to/package
```
This package intentionally skips 2 source collection(s) containing 2642 file(s). Those collections usually contain per-species artifacts and should be packaged only when a species/taxonomy ID is selected explicitly.
## License And Attribution
This repository aggregates embeddings derived from multiple upstream resources. Please check the per-embedding metadata and upstream sources for the applicable licenses and citation terms.
