Installation

Create a virtual environment.

conda create -n molgrapher python=3.11
conda activate molgrapher

Install MolGrapher and MolDepictor for CPU.

pip install -e .["cpu"]

Install MolGrapher and MolDepictor for GPU. (Tested for x86_64, Linux Ubuntu 20.04, CUDA 11.7, CUDNN 8.4)

pip install -e .["gpu"]

CUDA and CDNN versions can be edited in setup.py.

To install and run MolGrapher using Docker, please refer to README_DOCKER.md.

Model

Models are available on Hugging Face.

wget https://huggingface.co/ds4sd/MolGrapher/resolve/main/models/graph_classifier/gc_gcn_model.ckpt -P ./data/models/graph_classifier/
wget https://huggingface.co/ds4sd/MolGrapher/resolve/main/models/graph_classifier/gc_no_stereo_model.ckpt -P ./data/models/graph_classifier/
wget https://huggingface.co/ds4sd/MolGrapher/resolve/main/models/graph_classifier/gc_stereo_model.ckpt -P ./data/models/graph_classifier/
wget https://huggingface.co/ds4sd/MolGrapher/resolve/main/models/keypoint_detector/kd_model.ckpt -P ./data/models/keypoint_detector/

After downloading, the folder models from Hugging Face should be placed in: ./data/. Models can be selected by modifying attributes of GraphRecognizer (in ./molgrapher/models/graph_recognizer.py).

Inference

Your input images can be placed in the folder: ./data/benchmarks/default/.

bash molgrapher/scripts/annotate/run.sh

Output predictions are saved in: ./data/predictions/default/.

USPTO-30K Benchmark

USPTO-30K is available on Hugging Face.

  • USPTO-10K contains 10,000 clean molecules, i.e. without any abbreviated groups.
  • USPTO-10K-abb contains 10,000 molecules with superatom groups.
  • USPTO-10K-L contains 10,000 clean molecules with more than 70 atoms.

Synthetic Dataset

The synthetic dataset is available on Hugging Face. Images and graphs are generated using MolDepictor.

Training

To train the keypoint detector:

python3 ./molgrapher/scripts/train/train_keypoint_detector.py

To train the node classifier:

python3 ./molgrapher/scripts/train/train_graph_classifier.py
