🧬 DNABERT-Nicotiana-Stress-Predictor

This model is a fine-tuned version of DNABERT-Nicotiana for stress region prediction in DNA sequences. It was developed by the iGEM UGM-Indonesia team as part of the 2025 iGEM project.

📘 Overview

The DNABERT-Nicotiana-Stress-Predictor is designed to classify DNA sequences into stress and non-stress regions. This model leverages the DNABERT-2 architecture and has been fine-tuned on a custom dataset curated by the iGEM UGM team.

💡 Usage

You can use this model for DNA stress prediction tasks with Hugging Face Transformers.

from transformers import AutoTokenizer, BertForSequenceClassification
import torch

# Load tokenizer dan model
tokenizer = AutoTokenizer.from_pretrained("igemugm/dnabert-stress-predictor", trust_remote_code=True)
model = BertForSequenceClassification.from_pretrained("igemugm/dnabert-stress-predictor", trust_remote_code=True)

# Input DNA sequence
sequence = "ACGTAGCATCGGATCTATCTATCGACACTTGGTTATCGATCTACGAGCATCTCGTTAGC"
inputs = tokenizer(sequence, return_tensors="pt")

# Inference
with torch.no_grad():
    outputs = model(**inputs)
    predictions = torch.softmax(outputs.logits, dim=-1)
    predicted_class = torch.argmax(predictions, dim=1).item()

print("Predicted class:", predicted_class)  # 0 = non-stress, 1 = stress
print("Confidence scores:", predictions)
