R package for modeling single cell UMI expression data using regularized negative binomial regression

sctransform

R package for normalization and variance stabilization of single-cell RNA-seq data using regularized negative binomial regression

This packaged was developed by Christoph Hafemeister in Rahul Satija's lab at the New York Genome Center. Core functionality of this package has been integrated into Seurat, an R package designed for QC, analysis, and exploration of single cell RNA-seq data.

Quick start

devtools::install_github(repo = 'ChristophH/sctransform')
normalized_data <- sctransform::vst(umi_count_matrix)$y

Help

For usage examples see vignettes in inst/doc or use the built-in help after installation
