CodonTransformer is the ultimate tool for codon optimization, transforming protein sequences into optimized DNA sequences specific for your target organisms. Whether you are a researcher or a practitioner in genetic engineering, CodonTransformer provides a comprehensive suite of features to facilitate your work. By leveraging the Transformer architecture and a user-friendly Jupyter notebook, it reduces the complexity of codon optimization, saving you time and effort.

This is the pretrained model, for best results please use the finetuned model.

Use Case

For a guide on finetuning CodonTransformer, check out our GitHub.
For an interactive demo, check out our Google Colab Notebook.

After installing CodonTransformer, you can use:

import torch
from transformers import AutoTokenizer, BigBirdForMaskedLM
from CodonTransformer.CodonPrediction import predict_dna_sequence
from CodonTransformer.CodonJupyter import format_model_output
DEVICE = torch.device("cuda" if torch.cuda.is_available() else "cpu")


# Load model and tokenizer
tokenizer = AutoTokenizer.from_pretrained("adibvafa/CodonTransformer")
model = BigBirdForMaskedLM.from_pretrained("adibvafa/CodonTransformer-base").to(DEVICE)


# Set your input data
protein = "MALWMRLLPLLALLALWGPDPAAAFVNQHLCGSHLVEALYLVCGERGFFYTPKTRREAEDLQVGQVELGG"
organism = "Escherichia coli general"


# Predict with CodonTransformer
output = predict_dna_sequence(
    protein=protein,
    organism=organism,
    device=DEVICE,
    tokenizer=tokenizer,
    model=model,
    attention_type="original_full",
)
print(format_model_output(output))

The output is:
