DNA Methylation Data Analysis

How to use bisulfite-treated sequencing to study DNA methylation

Workshop Website

When?
15 - 17 Dec 2015

Where?
iad Pc-Pool, Rosa-Luxemburg-Straße 23, Leipzig, 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
  Introduction to NGS data analysis
 
8 am
-
12 am
  • Introduction to Illumina sequencing method 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)

  Linux for bioinformatics
 
1 pm
-
5pm
  • Introduction to the command line and important commands
  • Combining commands by piping and redirection
  • Introduction to bioinformatics file formats (e.g. FASTA, BED, VCF, WIG) and databases (e.g. UCSC, ENSEMBL)
  • Use of important bioinformatics toolkits (BEDtools, UCSCtools)
  • Introduction to R

Day 2 and 3
     DNA Methylation Analysis
8 am
-
5 pm
  • 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

  • Helene Kretzmer (University of Leipzig) is working on DNA methylation analyses using high-throughput sequencing since 2011. She is responsible for the bioinformatic analysis of MMML-Seq study of the International Cancer Genome Consortium (ICGC).
  • Dr. Christian Otto (CCR-BioIT) is one of the developers of the bisulfite read mapping tool segemehl and is an expert on implementing efficient algorithms for HTS data analyses.
  • Dr. David Langenberger (ecSeq Bioinformatics) started working with small non-coding RNAs in 2006. Since 2009 he uses HTS technolgies to investigate these short regulatory RNAs as well as other targets. He has been part of several large HTS projects, for example the International Cancer Genome Consortium (ICGC).
  • Dr. Mario Fasold (ecSeq Bioinformatics) has developed several bioinformatics tools such as the Bioconductor package AffyRNADegradation and the Larpack program package. Since 2011 he is specialized in the field of HTS data analysis and helped analysing sequecing data of several large consortium projects.

Our trainers for this workshop, Helene Kretzmer and Christian Otto, used their bisulfite analysis toolkit to analyze cancer data for the ICGC (International Cancer Genome Consortium) and just published the results in Nature Genetics

We will use exactly this toolkit in our workshop and Helene and Christian will train the participants in how to use it correctly!

Dear Lars, 

we will provide the machines. Every participant will get his/her own computer. You don't have to bring your laptop!

I am coming and hoping that the workshop will not be exclusively dedicated to the analysis of the human methylation, since I am working with plants

Can you confirm ?

ADD COMMENTlink written 2.0 years ago by Antonio R. Franco3.4k

Dear Antonio,

the examples we use in the course are only from human. In three days it is not possible to cover more than one species.

Nevertheless, you can use the same tools and analysis steps for your analysis in plants. Our trainers will surely answer all your questions regarding changes (e.g. different parameters settings) that should be performed when changing from human to plants. Furthermore, the detection of methylated non-CpGs, which occurs pretty often in plants, is included in the course. Thus, I am absolutely sure that you will be able to start analyzing your plants after the workshop.

Sorry, I double-checked with the trainers and this year, there will be two data sets: One from honey bee and one from human cancer

ADD REPLYlink written 2.0 years ago by David Langenberger8.0k

I just love the methylation business in bees..
