title: "mHapSuite: a Java toolkit for the analysis of mHaps" output: html_document: toc: true

Abstract

Bisulfite sequencing (BS-seq) remains the gold standard technique to detect DNA methylation profiles at single-nucleotide resolution. The DNA methylation status of CpG sites on the same fragment represents a discrete methylation haplotype (mHap). The mHap-level metrics were demonstrated to be promising cancer biomarkers and explain more gene expression variation than average methylation. However, most existing tools focus on average methylation and neglect mHap patterns. Previously, we have developped mHapTk, a comprehensive toolkit for the analysis of DNA methylation haplotypes. Here, we present mHapSuite, a Java reimplementation of mHapTk for the analysis of mhaps. mHapSuite shows significant improvment in terms of both functionality and efficiency.

Installation

It is written in Java, and should run in Windows, Linux and macOS with java 1.8 installed. The source code of mHapSuite is hosted in github and the jar file is ready to use.

Annotation files

In order to run mHapSuite, some annotation files are needed, including CpG position files and chromosome size files. CpG position files can be downloaed from this page and chromosome size files can be downloaded from UCSC genome browser.

Genome CpG sites chromosome size
hg19 hg19_CpG.gz
hg19_CpG.gz.tbi		 hg19.chrom.sizes
hg38 hg38_CpG.gz
hg38_CpG.gz.tbi		 hg38.chrom.sizes
mm9 mm9_CpG.gz
mm9_CpG.gz.tbi		 mm9.chrom.sizes

merge

This function merges multiple sorted mHap files, produce a single sorted mHap file.

tanghulu

This function is to visualize the methylation status of the reads that cover a given region. Tanghulu plot was originally introduced in CGmapTools.

When setting the --merge option, identical mHaps will be merged. This can be helpful when there are too many reads in a region.

java -jar mHapSuite-2.0-jar-with-dependencies.jar  tanghulu --mhapPath data/SRX8208802.mhap.gz --cpgPath idx/hg19_CpG.gz --region chr1:14435-14653 -tag SRX8208802 --merge

Sometimes, we may want to visualize the mHap patterns of different samples that were sequenced with different depth. With the --simulation option, a given number (20 by default) of mHaps were simulated to maximize the likelihood given the mHaps observed in each sample.

java -jar mHapSuite-2.0-jar-with-dependencies.jar  tanghulu --mhapPath data/SRX8208802.mhap.gz --cpgPath idx/hg19_CpG.gz --region chr1:14435-14653 -tag SRX8208802 --simulation

mHapView

The co-methylation level of pairwise CpGs are measure by linkage disequilibrium r-squared, caculated from individual reads rather than mean methylation. This tool calculates the R2 scores between pairs of CpG sites in a given region. Negative values indicate negative correlation. It can also plot the CpG linkage, which is similar to the Haploview plot.

usage: java -jar mHapSuite-2.0-jar-with-dependencies.jar mHapView --mhapPath <mhap.gz> --cpgPath <CpG.gz> [--region chr:start-end] [--bedPath <in.bed>] --tag <tag> [--outFormat outFormat] [--strand strand]
