[!WARNING]
This is a model trained on publicly available data. While we've done our best to curate the data, the model performance can still improve. Proceed with caution.

In this repo, we have our baseline model. It is a single task CheMeleon model trained on pIC50 data curated from ChEMBL 37 for hERG.

It is a no split model, meaning it has been trained with no data allocated to validation and test sets and with just a training set of 1.0.

Getting Started

We highly recommend you have the Anvil framework from openadmet-models installed in an environment (called openadmet-models) for ease of use and full utilization of OpenADMET's models. For full documentation, visit our website here. If you'd like to see some more examples on how to use Anvil, see our demos here.

Option A: Downloading & running the model with Github

You can install openadmet-models via our GitHub package. If you want the latest development version, clone the repository and install in editable mode:

git clone git@github.com:OpenADMET/openadmet-models.git

Set up an environment using the provided files in devtools/conda-envs.

cd openadmet-models/
conda env create -f devtools/conda-envs/openadmet-models.yaml
conda activate openadmet-models
pip install -e .

If you want to use GPU acceleration, ensure you have the appropriate CUDA toolkit installed and use the openadmet-models-cuda.yaml file instead:

conda env create -f devtools/conda-envs/openadmet-models-gpu.yaml
conda activate openadmet-models
pip install -e .

IMPORTANT NOTE You will also need git lfs installed.
After installing Anvil, clone the model repo:

git clone https://huggingface.co/openadmet/herg-chemeleon-baseline/

Change to the repo directory. Ensure you have git lfs installed for the repo and get the large model files:

git lfs install
git lfs pull

You are now ready to use the model!

Option B: Downloading & running the model with Docker

Alternatively, you can also use Docker to spin up a containerized pre-installed environment to run openadmet-models. Just be sure you are mounting the correct folder (./herg-chemeleon-baseline) where you've downloaded the model.

If you're using a gpu, run:

docker run -it --user=root --rm  \
    -v ./herg-chemeleon-baseline:/home/mambauser/model:rw \
    --runtime=nvidia \
    --gpus all \
    ghcr.io/openadmet/openadmet-models:main

Otherwise, for cpu only:

docker run -it --user=root --rm  \
    -v ./herg-chemeleon-baseline:/home/mambauser/model:rw \
    ghcr.io/openadmet/openadmet-models:main

Using the model

We will use this model for inference, aka predict the pIC50 values of a set of molecular compounds unseen to the model. For demonstration purposes, we have provided a small subset of compounds from a ZINC deck in the file compounds_for_inference.csv.

The generic command to run our inference pipeline is:

bash

openadmet predict \
    --input-path <the path to the data to predict on> \
    --input-col <the column to of the data to predict on, often SMILES> \
    --model-dir <the anvil_training directory of the model to predict with> \
    --output-csv <the path to an output CSV to save the predictions to> \
    --accelerator <whether to use gpu or cpu, defaults to gpu>

You can run this directly in your command line, OR you can use the bash script we've provided, run_model_inference.sh.

For our working example, this command becomes:

bash

openadmet predict \
    --input-path compounds_for_inference.csv \
    --input-col OPENADMET_CANONICAL_SMILES \
    --model-dir anvil_training/ \
    --output-csv predictions.csv \
    --accelerator cpu

You can easily substitute your own set of compounds, simply modify the --input-path and --input-col arguments for your specific dataset.

In our example, this outputs a file called predictions.csv which will have predicted (the OADMET_PRED columns) pIC50 values:

OADMET_PRED_chemprop-chembl_pchembl_value_mean,
OADMET_STD_chemprop-chembl_pchembl_value_mean

NOTE In this example, the standard deviation (OADMET_STD) columns are empty because uncertainty cannot be estimated unless running inference on an ensemble of models. For further details, visit our demo specifically about ensembling.
