IntegrAO

This is the official codebase for Integrate Any Omics: Towards genome-wide data integration for patient stratification.[arXiv]

🔨 Hardware requirements

IntegrAO package requires only a standard computer with enough RAM to support the in-memory operations.

🔨 Installation

This package requires Python version 3.6 or greater. If you want to utilize GPU computation, make sure you install the matching Pytorch and CUDA versions.

  1. Create a virtual environment: conda create -n integrAO python=3.10 -y and conda activate integrAO
  2. Install Pytorch 2.1.0: pip install torch==2.1.0 torchvision==0.16.0 torchaudio==2.1.0 --index-url https://download.pytorch.org/whl/cu118
  3. Install Pytorch-geometric: pip install torch_geometric
  4. Install other requirements: pip install -r requirement.txt
  5. Download code: git clone https://github.com/bowang-lab/IntegrAO.git

🧬 Introduction

High-throughput omics profiling advancements have greatly enhanced cancer patient stratification. However, incomplete data in multi-omics integration presents a significant challenge, as traditional methods like sample exclusion or imputation often compromise biological diversity and dependencies. Furthermore, the critical task of accurately classifying new patients with partial omics data into existing subtypes is commonly overlooked. We introduce IntegrAO, an unsupervised framework integrating incomplete multi-omics and classifying new biological samples. IntegrAO first combines partially overlapping patient graphs from diverse omics sources and utilizes graph neural networks to produce unified patient embeddings.

An overview of IntegrAO can be seen below.
