This is the official implementation of the paper "RiNALMo: General-Purpose RNA Language Models Can Generalize Well on Structure Prediction Tasks".
Ribonucleic acid (RNA) plays a variety of crucial roles in fundamental biological processes. Recently, RNA has become an interesting drug target, emphasizing the need to improve our understanding of its structures and functions. Over the years, sequencing technologies have produced an enormous amount of unlabeled RNA data, which hides important knowledge and potential. Motivated by the successes of protein language models, we introduce RiboNucleic Acid Language Model (RiNALMo) to help unveil the hidden code of RNA. RiNALMo is the largest RNA language model to date with 650 million parameters pre-trained on 36 million non-coding RNA sequences from several available databases. RiNALMo is able to extract hidden knowledge and capture the underlying structure information implicitly embedded within the RNA sequences. RiNALMo achieves state-of-the-art results on several downstream tasks. Notably, we show that its generalization capabilities can overcome the inability of other deep learning methods for secondary structure prediction to generalize on unseen RNA families.
Use following commands for the installation (Prerequisites: Python>=3.8 and CUDA>=11.8):
git clone https://github.com/lbcb-sci/RiNALMo
cd RiNALMo
pip install .
pip install flash-attn==2.3.2After installation you can easily use RiNALMo to obtain nucleotide representations:
import torch
from rinalmo.pretrained import get_pretrained_model
DEVICE = "cuda:0"
model, alphabet = get_pretrained_model(model_name="giga-v1")
model = model.to(device=DEVICE)
model.eval()
seqs = ["ACUUUGGCCA", "CCCGGU"]
tokens = torch.tensor(alphabet.batch_tokenize(seqs), dtype=torch.int64, device=DEVICE)
with torch.no_grad(), torch.cuda.amp.autocast():
outputs = model(tokens)
print(outputs["representation"])- Clone the repo.
git clone https://github.com/lbcb-sci/RiNALMo
cd RiNALMo- Create conda environment. All external dependencies should be contained in
environment.yml.
# create conda environment for RiNALMo

cd ..You can also download pre-trained weights for smaller RiNALMo models (RiNALMo-148M (mega) and RiNALMo-33,5M (micro)) at https://drive.google.com/drive/folders/1vGk3gY8c01o0wQfpmyX5vOY4Wy8EbQS5.
We provide pre-trained RiNALMo weights and fine-tuned weights for three downstream tasks: mean ribosome loading prediction, secondary structure prediction and splice-site prediction.
For both evaluation and fine-tuning use train_<downstream_task>.py scripts.
In order to evaluate the provided fine-tuned RiNALMo models and prediction heads, please run the scripts using the following input arguments:
# skip fine-tuning and run the evaluation on the test set
--test_only
# path to the '.pt' file containing fine-tuned model weights
--init_params
# dataset on which you would like to evaluate the fine-tuned model
--dataset
# download and prepare data (if needed)
--prepare_data
# Directory that will contain or already contains training, validation and test data
data_dir
# directory for all the output files
--output_dirTo evaluate the fine-tuned RiNALMo model and prediction head on archiveII 5S rRNA test dataset for secondary structure prediction, use the rinalmo_giga_ss_archiveII-5s_ft.pt weights. Here, we provide an example run command.
python train_sec_struct_prediction.py ./ss_data --test_only --init_params ./weights/rinalmo_giga_ss_archiveII-5s_ft.pt --dataset archiveII_5s --prepare_data --output_dir ./outputs/archiveII/5s/ --accelerator gpu --devices 1
In order to fine-tune RiNALMo, use --pretrained_rinalmo_weights ./weights/rinalmo_giga_pretrained.pt input argument. Use --help to learn about other available arguments. For the splice-site prediction task, the dataset and data preprocessing code are available at https://git.unistra.fr/nscalzitti/spliceator.git.
