DNA Methylation Data Analysis

How to use bisulfite-treated sequencing to study DNA methylation

Link: DNA Methylation Workshop

When? November 29 - December 1, 2017

Where? PC-College, Stresemannstraße 78, 10963 Berlin, Germany

Scope and Topics

The purpose of this workshop is to get a deeper understanding of the use of bisulfite-treated DNA in order to analyze the epigenetic layer of DNA methylation. Advantages and disadvantages of the so-called 'bisulfite sequencing' and its implications on data analyses will be covered. The participants will be trained to understand bisulfite-treated NGS data, to detect potential problems/errors and finally to implement their own pipelines. After this course they will be able to analyze DNA methylation and create ready-to-publish graphics.

By the end of this workshop the participants will:

  • be familiar with the sequencing method of Illumina
  • understand how bisulfite sequencing works
  • be aware of the mapping problem of bisulfite-treated data
  • understand how bisulfite-treated reads are mapped to a reference genome
  • be familiar with common data formats and standards
  • know relevant tools for data processing
  • automate tasks with shell scripting to create reusable data pipelines
  • perform basic analyses (call methylated regions, perform basic downstream analyses)
  • plot and visualize results (ready-to-publish)
  • be able to reuse all analyses

Workshop Structure and Program

This workshop has been redesigned and adapted to the needs of beginners in the field of NGS bioinformatics. The workshop comprises three course modules.


Day 1 (09:00 AM - 12:00 PM)

NGS Technologies

  • Introduction to sequencing technologies from a data analysts view
  • Raw sequence files (FASTQ format)
  • Preprocessing of raw reads: Idea of adapter clipping and quality trimming
  • Mapping output (SAM/BAM format)

Day 1 (01:00 PM - 05:00 PM)

Practical Bioinformatics (with Linux)

  • Introduction to the command line and important commands
  • Combining commands by piping and redirection
  • Introduction to bioinformatics file formats (e.g. FASTA, BED) and databases (e.g. UCSC)

Day 2 - 4 (09:00 AM - 05:00 PM)

Introduction to Bisulfite-Seq data analysis

  • Introduction to Bisulfite Sequencing
  • Read Mapping (special alignment method for bisulfite-treated reads)
  • Quality Control
  • Data Formats (e.g. vcf, bed, bedgraph, bigwig)
  • Overview Statistics
  • Tools and Databases (e.g. UCSCtools, BEDtools, UCSC GenomeBrowser)
  • Visualizing the DNA methylation genome-wide (e.g. Circos Plot, R) or in specific regions/genes (e.g. UCSC, IGV)
  • From positions to regions: advantages and disadvantages of segmentation, windowing, and smoothing
  • Identification of Differentially Methylated Regions (DMRs)
  • Non-CpG Analysis (How to find methylated non-CpGs)

Target Audience

  • biologists or data analysts with no or little experience in analyzing bisulfite sequencing data

Requirements

  • basic understanding of molecular biology (DNA, RNA, gene expression, PCR, ...)
  • the data analysis will partly take place on the linux commandline. Is is therefore beneficial to be familiar with the commandline and in particular the commands covered in the Learning the Shell Tutorial

Included in the Course

  • Course materials
  • Catering
  • Conference Dinner

Trainers

  • Dr. Helene Kretzmer (Max Planck Institut for Molecular Genetics) is working on DNA methylation analyses using high-throughput sequencing since 2011. She was responsible for the bioinformatic analysis of MMML-Seq study of the International Cancer Genome Consortium (ICGC).
  • Dr. Christian Otto (ecSeq Bioinformatics GmbH) is one of the developers of the bisulfite read mapping tool segemehl and is an expert on implementing efficient algorithms for HTS data analyses.
