MERINGUE characterizes spatial gene expression heterogeneity in spatially resolved single-cell transcriptomics data with non-uniform cellular densities.

The overall approach is detailed in the following publication: Miller, B., Bambah-Mukku, D., Dulac, C., Zhuang, X. and Fan, J. Characterizing spatial gene expression heterogeneity in spatially resolved single-cell transcriptomics data with nonuniform cellular densities. Genome Research. May 2021.

Overview

MERINGUE is a computational framework based on spatial auto-correlation and cross-correlation analysis.

You can use MERINGUE to:

  • Identify genes with spatially heterogeneous expression
  • Group significantly spatially variable genes into primary spatial gene expression patterns
  • Identify pairs of genes with complementary expression patterns in spatially co-localized cell-types that may be indicative of cell-cell communication
  • Integrate density-agnostic spatial distance weighting to perform spatially-informed transcriptional clustering analysis

In a manner that:

  • Accomodates 2D, multi-section, and 3D spatial data
  • Is robut to variations in cellular densities, distortions, or warping common to tissues
  • Is highly scalable to enable analysis of 10,000s of genes and 1,000s of cells within minutes
  • Is applicable to diverse spatial transcriptomics technologies

Installation

To install MERINGUE, we recommend using remotes:

# install.packages("remotes")
require(remotes)
remotes::install_github('JEFworks-Lab/MERINGUE', build_vignettes = TRUE)
