Domain Invariant Representation through Adversarial Calibration (DIRAC), a graph neural network to integrate spatial multi-omic data into a unified domain

DIRAC (Domain Invariant Respresentation through Adversatial Calibration)

Spatially resolved integration of multi-omics with DIRAC highlights cell-specific remodeling

DIRAC is a Python package, written in PyTorch and based on Scanpy.

DIRAC is a graph neural network to integrate spatial multi-omic data into a unified domain-invariant embedding space and to automate cell-type annotation by transferring labels from reference spatial or single-cell multi-omic data.

DIRAC primarily includes two integration paradigms: vertical integration and horizontal integration, which differ in their selection of anchors. In vertical integration, multiple data modalities from the same cells are jointly analyzed, using cell correspondences in single-cell data or spot correspondences in spatial data as anchors for alignment. In horizontal integration, the same data modality from distinct groups of cells is aligned using genomic features as anchors. The best way to familiarize yourself with DIRAC is to check out our tutorial and our documentation.

How to install DIRAC

To install DIRAC, make sure you have PyTorch and Scanpy installed. If you need more details on the dependences, look at the environment.yml file.

• set up conda environment for DIRAC

    conda env create -f environment.yml

• install sodirac from shell:

    conda activate dirac-env
    pip install sodirac

• To start using DIRAC, import DIRAC in your jupyter notebooks or/and scripts

    import sodirac as sd

Installing within a conda environment is recommended.
