:fire:DrugOOD:fire:: OOD Dataset Curator and Benchmark for AI Aided Drug Discovery

This is the official implementation of the DrugOOD project, this is the project page: https://drugood.github.io/

Environment Installation

You can install the conda environment using the drugood.yaml file provided:

!git clone https://github.com/tencent-ailab/DrugOOD.git
!cd DrugOOD
!conda env create --name drugood --file=drugood.yaml
!conda activate drugood

Then you can go to the demo at demo/demo.ipynb which gives a quick practice on how to use DrugOOD.

Demo

For a quick practice on using DrugOOD for dataset curation and OOD benchmarking, one can refer to the demo/demo.ipynb.

Dataset Curator

First, you need to generate the required DrugOOD dataset with our code. The dataset curator currently focusing on generating datasets from CHEMBL. It supports the following two tasks:

• Ligand Based Affinity Prediction (LBAP).
• Structure Based Affinity Prediction (SBAP).

For OOD domain annotations, it supports the following 5 choices.

• Assay.
• Scaffold.
• Size.
• Protein. (only for SBAP task)
• Protein Family. (only for SBAP task)

For noise annotations, it supports the following three noise levels. Datasets with different noises are implemented by filters with different levels of strictness.

• Core.
• Refined.
• General.

At the same time, due to the inconvenient conversion between different measurement type (E.g. IC50, EC50, Ki, Potency), one needs to specify the measurement type when generating the dataset.

How to Run and Reproduce the 96 Datasets?

Firstly, specifiy the path of CHEMBL database and the directory to save the data in the configuration file: configs/_base_/curators/lbap_defaults.py for LBAP task or configs/_base_/curators/sbap_defaults.py for SBAP task.
The source_root="YOUR_PATH/chembl_29_sqlite/chembl_29.db" means the path to the chembl29 sqllite file. The target_root="data/" specifies the folder to save the generated data.

Note that you can download the original chembl29 database with sqllite format from http://ftp.ebi.ac.uk/pub/databases/chembl/ChEMBLdb/releases/chembl_29/chembl_29_sqlite.tar.gz.

The built-in configuration files are located in:
configs/curators/. Here we provide the 96 config files to reproduce the 96 datasets in our paper. Meanwhile, you can also customize your own datasets by changing the config files.

Run tools/curate.py to generate dataset. Here are some examples:

Generate datasets for the LBAP task, with assay as domain, core as noise level, IC50 as measurement type, LBAP as task type.:

python tools/curate.py --cfg configs/curators/lbap_core_ic50_assay.py

Generate datasets for the SBAP task, with protein as domain, refined as noise level, EC50 as measurement type, SBAP as task type.:

python tools/curate.py --cfg configs/curator/sbap_refined_ec50_protein.py

Benchmarking SOTA OOD Algorithms

Currently we support 6 different baseline algorithms:

• ERM
• IRM
• GroupDro
• Coral
• MixUp
• DANN

Meanwhile, we support various GNN backbones:

• GIN
• GCN
• Weave
• ShcNet
• GAT
• MGCN
• NF
• ATi-FPGNN
• GTransformer

And different backbones for protein sequence modeling:

• Bert
• ProteinBert

How to Run?

Firstly, run the following command to install.

python setup.py develop

Run the LBAP task with ERM algorithm:

python tools/train.py configs/algorithms/erm/lbap_core_ec50_assay_erm.py

If you would like to run ERM on other datasets, change the corresponding options inside the above config file. For example, ann_file = 'data/lbap_core_ec50_assay.json' specifies the input data.

Similarly, run the SBAP task with ERM algorithm:

python tools/train.py configs/algorithms/erm/sbap_core_ec50_assay_erm.py
