GOAT: Gene-level biomarker discovery from multi-Omics data using graph ATtention neural network for eosinophilic asthma subtype

Note

GOAT 2.0 has been released. Checkout here , please.

workflow
We propose a novel deep graph attention model for biomarker discovery for the asthma subtype by incorporating complex interactions between biomolecules and capturing key biomarker candidates using the attention mechanism.

Setup

Create docker image

You can build a docker image from Dockerfile.

# Pull base image from docker hub
docker pull dabinjeong/cuda:10.1-cudnn7-devel-ubuntu18.04

# Build docker image
docker build --tag biomarker:0.1.1 .

You can also download the docker image from Docker hub (https://hub.docker.com/repository/docker/dabinjeong/biomarker/general).

docker pull dabinjeong/biomarker:0.1.1

Install workflow manager: Nextflow

conda create -n biomarker python=3.9
conda activate biomarker
conda install -c bioconda nextflow=21.04.0

Run

nextflow run biomarker_discovery.nf -c pipeline.config -with-docker biomarker:0.1.1

goat_multi-omics_biomarker's Issues

Questions about the 'input_graph' and 'teleport_graph'?

Hi, thanks for your great work! I'm currently attempting to execute the 'network_propagation.py' script.
I'm a bit confused about the input data requirements for 'input_graph' and 'teleport_graph'. Could you please explain the meaning of the data and provide guidance on where to locate the necessary input data?

GOAT on other Multi Omics Datasets

Hello,
thank you very much for providing GOAT to the community. I have been able to reproduce the results of your paper and i was wondering if the tool could be applied for another multi omics data. I have different data modalities from the same patient together with clinical data and i would like to test the method on them.

Any reply would be really appreicated.

Thank you in advance,
Tommaso
