# ocampoatac2

Alternate packaged implementation loaded from the authors' GitHub final_coefs.tsv; it represents the same uncorrected final ATAC-clock target, not a deployable cell-composition-corrected clock.

| | |
|---|---|
| **Predicts** | chronological age |
| **Species** | Homo sapiens |
| **Tissue** | peripheral blood mononuclear cells |

## Use with pyaging

```python
import pyaging as pya

pya.pred.predict_age(adata, ["ocampoatac2"])
```
