Installation

PyPI

Note Installing scSLAT within a new conda environment is recommended.

Warning Old NVIDIA driver may raise error.

First, we create a clean environment and install scSLAT from PyPI. Then we also need install dependencies for pyg manually via install_pyg_dependencies.

conda create -n scSLAT python=3.11 -y && conda activate scSLAT
pip install scSLAT
install_pyg_dependencies

Docker

You can pull the docker image directly from Docker Hub or refer to the Dockerfile to build it.

docker pull huhansan666666/slat:latest

Development version

For development purpose, clone this repo and install:

git clone git@github.com:gao-lab/SLAT.git && cd SLAT
pip install -e ".[dev,docs]"
install_pyg_dependencies

Reproduce manuscript results

1. Please follow the env/README.md to install all dependencies. Please checkout the repository to v0.2.1 before install scSLAT.
2. Download and pre-process data follow the data/README.md.
3. Whole benchmark and evaluation procedure can be found in /benchmark and /evaluation, respectively.
4. Every case study is recorded in the /case directory in the form of jupyter notebook.
