# Malinois

Malinois predicts cis-regulatory activity of 200 bp human sequences in K562, HepG2
and SK-N-SH.


[Machine-guided design of cell-type-targeting cis-regulatory
elements](https://doi.org/10.1038/s41586-024-08070-z) (Gosai et al., Nature 2024).

This repository holds the published checkpoint (`20211113_021200`), converted to
safetensors from `gs://tewhey-public-data/CODA_resources/` with no retraining or
modification.

For variant effect prediction, use
[MPAC](https://huggingface.co/saarantras1/MPAC) instead.

## Usage

```python
from modeling_malinois import MalinoisModel

model = MalinoisModel.from_pretrained("saarantras1/malinois").eval()

preds = model.predict(["ACGT" * 50])   # (n, 3): K562, HepG2, SKNSH
```

Use `predict` rather than calling the model directly: it adds the MPRA vector
context the model was trained with (a bare 200mer is not valid input) and averages
over both strands. Skipping either step returns plausible-looking but wrong numbers
instead of an error.

Note on strands: `predict` reverse-complements the 200 bp insert and re-flanks it in
the forward orientation, following `src/vcf_predict.py` in the upstream code base.
The CODA tutorial notebook instead flips the assembled 600 bp construct. Both appear in upstream
code; this repository uses the former.
