AlphaGenome
Model Introduction
AlphaGenome is a DNA sequence model developed by Google DeepMind. It accepts DNA intervals of up to 1 Mbp as input and predicts a range of functional genomic signals for genomic track prediction and regulatory variant-effect scoring.

Model Description
AlphaGenome is implemented in JAX / Flax and supports genomic interval inference, variant effect scoring, track evaluation, and example fine-tuning workflows. This model package is accompanied by the Hugging Face dataset OneScience-Sugon/alphagenome_dataset, which enables rapid local validation.
Use Cases
| Scenario | Description |
|---|---|
| Genomic interval prediction | Takes a reference-genome FASTA file, a chromosome, and genomic interval coordinates as input and outputs predicted tracks such as ATAC, DNase, CAGE, RNA-seq, and ChIP |
| Variant effect scoring | Takes either a VCF file or built-in example variants as input, compares predictions for the reference and variant sequences, and produces a variant scoring table |
| Track prediction evaluation | Uses validation data from the AlphaGenome dataset to compute regression evaluation metrics across different assay bundles |
| Fine-tuning experiments | Validates a fine-tuning workflow using custom reference genomes, interval CSVs, and BigWig signal files |
| Hugging Face / OneCode execution | After downloading the model project and accompanying dataset, quickly verifies that the scripts run correctly in a life-sciences runtime environment |
Usage Guide

2. Manual Installation and Usage
Hardware Requirements
- GPU or DCU is recommended.
- A CPU can be used for import checks and lightweight configuration tests; full training and inference will be slow.
- DCU users must install DTK in advance. DTK 25.04.2 or later is recommended, or a OneScience-recommended version matching the current cluster.
Environment Check
- NVIDIA GPU:
nvidia-smi
- Hygon DCU:
hy-smi
Download the Model Package
hf download --model OneScience-Sugon/alphagenome --local-dir ./alphagenome
cd alphagenome
Install the Runtime Environment
DCU Environment
# Activate DTK and CONDA first
conda create -n onescience311 python=3.11 -y
conda activate onescience311
# uv installation supported
pip install onescience[bio-dcu] -i http://mirrors.onescience.ai:3141/pypi/simple/ --trusted-host mirrors.onescience.ai
After installation, return to the model package directory:
cd ./alphagenome
Data for Inference, Evaluation, and Fine-Tuning
The OneScience community has uploaded the data required for AlphaGenome inference, evaluation, and fine-tuning to Hugging Face: OneScience-Sugon/alphagenome_dataset. After downloading, place the data in the data/ directory under the model package.
hf download --dataset OneScience-Sugon/alphagenome_dataset --local-dir ./data
Model Weights
The repository already includes weight/alphagenome-all-folds, and all scripts allow the model weights directory to be specified via --model_dir.
Preparing Weights
If using local weights, place the AlphaGenome Orbax checkpoint in the following directory:
weight/
alphagenome-all-folds/
_CHECKPOINT_METADATA
_METADATA
...
When running in a shared environment, you can also reuse centrally managed model and dataset directories via environment variables:
export ONESCIENCE_MODELS_DIR=/path/to/onescience/models
export ONESCIENCE_DATASETS_DIR=/path/to/onescience/datasets
Scripts look in the following locations first:
${ONESCIENCE_MODELS_DIR}/AlphaGenome/alphagenome-all-folds${ONESCIENCE_DATASETS_DIR}/AlphaGenome
If the above environment variables are not set, the scripts fall back to the following paths under the current model package:
weight/alphagenome-all-foldsdata/
Interval Inference
bash scripts/inference.sh
Equivalent Python command example:
python scripts/run_inference.py \
--fasta_path ./data/reference/HOMO_SAPIENS/GRCh38.p13.genome.fa \
--model_dir ./weight/alphagenome-all-folds \
--chromosome chr19 \
--start 10587331 \
--end 11635907 \
--output_dir ./outputs
Inference results are saved to outputs/.
Variant Effect Scoring
bash scripts/run_variant.sh
To specify a VCF input:
python scripts/run_variant_scoring.py \
--vcf_path ./data/example.vcf \
--fasta_path ./data/reference/HOMO_SAPIENS/GRCh38.p13.genome.fa \
--model_dir ./weight/alphagenome-all-folds \
--output_dir ./outputs_variant
Scoring results are saved as a CSV file.
Track Prediction Evaluation
bash scripts/run_track.sh
You can also explicitly specify data and output paths:
python scripts/run_track_prediction_eval.py \
--model_dir ./weight/alphagenome-all-folds \
--model_version ALL_FOLDS \
--data_dir ./data/v1/train \
--output_path ./outputs_track/eval_results.csv
Fine-Tuning Example
python scripts/run_finetuning.py \
--fasta_path ./data/reference/HOMO_SAPIENS/GRCh38.p13.genome.fa \
--regions_csv ./data/finetune_regions.csv \
--bigwig_paths ./data/sample_atac.bw \
--output_dir ./finetuned_model \
--num_steps 1000 \
--batch_size 2
Data Format
It is recommended to download the Hugging Face dataset OneScience-Sugon/alphagenome_dataset to data/ under the model package. The default directory structure is as follows:
data/
reference/
HOMO_SAPIENS/
GRCh38.p13.genome.fa
GRCh38.p13.genome.fa.fai
v1/
train/
...
In this structure:
reference/HOMO_SAPIENS/GRCh38.p13.genome.fais the human reference genome FASTA..faiis the FASTA index file.v1/train/is the data directory used for track prediction evaluation.- Custom fine-tuning also requires an interval CSV file with column names
chromosome,start,end, as well as one or more BigWig signal files.
