route-distances

License Tests codecov Code style: black

This repository contains tools and routines to calculate distances between synthesis routes and to cluster them.

This repository is mainly intended for developers and researchers. If you want a fully functional tool that is easy to use, please consider looking into the AiZynthFinder project.

Prerequisites

Before you begin, ensure you have met the following requirements:

  • Linux, Windows or macOS platforms are supported - as long as the dependencies are supported on these platforms.

  • You have installed anaconda or miniconda with python 3.9 to 3.11

The tool has been developed on a Linux platform, but the software has been tested on Windows 10 and macOS Catalina.

Installation

For users

Setup your python environment and then run

pip install route-distances

For developers

First clone the repository using Git.

Then execute the following commands in the root of the repository

conda env create -f conda-env.yml
conda activate routes-env
poetry install

the route_distances package is now installed in editable mode.

Usage

The tool will install the cluster_aizynth_output that is used to calculate distances and clusters for AiZynthFinder output

cluster_aizynth_output --files finder_output1.hdf5 finder_output2.hdf5 --output finder_distances.hdf5 --nclusters 0 --model ted

This will perform TED calculations and add a column distance_matrix with the distances and column cluster_labels with the cluster labels for each route to the output file.

An ML model for fast predictions can be found here: https://zenodo.org/record/4925903.

This can be used with the cluster_aizynth_output tool

cluster_aizynth_output --files finder_output1.hdf5 finder_output2.hdf5 --output finder_distances.hdf5 --nclusters 0 --model chembl_10k_route_distance_model.ckpt

For further details, please consult the documentation.

Development

Testing

Tests uses the pytest package, and is installed by poetry

Run the tests using:

pytest -v

Documentation generation

The documentation is generated by Sphinx from hand-written tutorials and docstrings

The HTML documentation can be generated by

invoke build-docs
