High dimensional weighted gene co-expression network analysis
high dimensional WGCNA ![](https://github.com/smorabit/hdWGCNA/raw/dev/man/figures/logo.png)
hdWGCNA is an R package for performing weighted gene co-expression network analysis (WGCNA) in high dimensional transcriptomics data such as single-cell RNA-seq or spatial transcriptomics. hdWGCNA is highly modular and can construct context-specific co-expression networks across cellular and spatial hierarchies. hdWGNCA identifies modules of highly co-expressed genes and provides context for these modules via statistical testing and biological knowledge sources. hdWGCNA uses datasets formatted as Seurat objects. Check out the hdWGCNA in single-cell data tutorial or the hdWGCNA in spatial transcriptomics data tutorial to get started.
Seurat v5 compatibility As of hdWGCNA v0.3.00 Seurat version 5 is now supported in addition to Seurat v4.
If you use hdWGCNA in your research, please cite the following papers in addition to the original WGCNA publication:
Installation
We recommend creating an R conda environment environment for hdWGCNA.
# create new conda environment for R
conda create -n hdWGCNA -c conda-forge r-base r-essentials
# activate conda environment
conda activate hdWGCNA
Next open R and install the required dependencies:
- Bioconductor, an R-based software ecosystem for bioinformatics and biostatistics.
- Seurat, a general-purpose toolkit for single-cell data science.
- WGCNA, a package for co-expression network analysis.
- igraph, a package for general network analysis and visualization.
- devtools, a package for package development in R.
# install BiocManager
install.packages("BiocManager")
# install Bioconductor core packages
BiocManager::install()
# install additional packages:
BiocManager::install(c("WGCNA", "igraph", "devtools", "GeneOverlap", "ggrepel", "UCell"))
devtools::install_github("NightingaleHealth/ggforestplot")
# install Seurat v5
install.packages("Seurat")
# alternatively, install Seurat v4
install.packages("Seurat", repos = c("https://satijalab.r-universe.dev', 'https://cloud.r-project.org"))
Now you can install the hdWGCNA package using devtools
.
devtools::install_github('smorabit/hdWGCNA', ref='dev')
