# KOLF2.1J Perturbation Cell Atlas — raw `.h5ad`
This repository is a **mirror** of the raw AnnData (`.h5ad`) files from the
**KOLF2.1J Perturbation Cell Atlas**, a genome-scale CRISPRi Perturb-seq atlas of
human induced pluripotent stem cells (iPSCs).
> **This is not original work by the uploader.** The data were produced by Doctor,
> Nourreddine, and Mali, released under **CC BY 4.0**, and are re-hosted here only
> to make the raw `.h5ad` files easier to download. All credit belongs to the
> original authors; please cite them (see **Citation** below).

All files are [AnnData](https://anndata.readthedocs.io/) `.h5ad` (HDF5). Sizes and
MD5 checksums are listed below; verify after download with `md5sum`.

`checksums.md5` in this repo contains the same checksums in `md5sum -c` format.
> **Note on the large file.** `KOLF_Pan_Genome_QC_Filtered.h5ad` is ~176 GiB. Use
> streaming/backed reads (`anndata.read_h5ad(path, backed="r")`) unless you have
> enough RAM to load it in full.
## Usage
```python
from huggingface_hub import hf_hub_download
import anndata as ad
path = hf_hub_download(
repo_id="Boom5426/KOLF",
repo_type="dataset",
filename="KOLF_Chromatin_Modifiers_Strong_Perturbations.h5ad",
)
adata = ad.read_h5ad(path, backed="r")
print(adata)
```
