nshen7/vmrseq

An R package for detecting cell-to-cell variably methylated regions (VMRs) from single-cell bisulfite sequencing leveraging probabilistic models.

vmrseq: Detecting variably methylated regions (VMRs) from single-cell bisulfite sequencing

The R package vmrseq is a novel computational tool developed for pinpointing variably methylated regions (VMRs) in scBS-seq data without prior knowledge on size or location. High-throughput single-cell measurements of DNA methylation allows studying inter-cellular epigenetic heterogeneity, but this task faces the challenges of sparsity and noise. vmrseq overcomes these challenges and identifies variably methylated regions accurately and robustly.

Installation

You can install the development version of vmrseq in R from GitHub with:

# install.packages("devtools")
devtools::install_github("nshen7/vmrseq")

Online Vignette

• An online vignette of 'Get Started' on the vmrseq package can be found at https://rpubs.com/nshen7/vmrseq-vignette.
