A Beginner's Guide to RNA-Seq Data Analysis

Quality Control, Read Mapping, Visualization and Downstream Analyses

1 - 5 February 2016

iad Pc-Pool, Rosa-Luxemburg-Straße 23, Leipzig, Germany


Scope and Topics

The purpose of this workshop is to get a deeper understanding in Next-Generation Sequencing (NGS) with a special focus on bioinformatics issues. Additionally, all workshop participants should be enabled to perform important tasks of NGS data analysis tasks themselves. 

The first workshop module is an introduction to data analysis using Linux, assuring that all participants are able to follow the practical parts. The second module dicusses advantages and disadvantages of current sequencing technologies and their implications on data analysis. The most important NGS file formats (fastq, sam/bam, bigWig, etc.) are introduced and one proceeds with first hands-on analyses (QC, mapping, visualization). You will learn how to read and interprete QC plots, clip adapter sequences and/or trim bad quality read ends, get bioinformatics backgrounds about the read mapping and understand its problems (dynamic programming, alignment visualization, NGS mapping heuristics, etc.), perform your own mapping statistics and visualize your data in different ways (IGV, UCSC, etc.). The last module adresses a specific applications of NGS: RNA-seq data analysis and detection of differentially expressed genes.

Workshop Structure

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

  1. Linux for Bioinformatics:
    This module will introduce the essential tools and file formats required for NGS data analysis. It helps to overcome the first hurdles when entering this (for NGS analyses) unavoidable operating system.
  2. Introduction to NGS data analysis:
    Different methods of NGS will be explained, the most important notations be given and first analyses be performed. This course covers essential knowledge for analysing data of many different NGS applications. 
  3. RNA-seq Data Analyses: RNA-Seq for model-organisms

Target Audience

  • biologists or data analysts with no or little experience in analyzing RNA-Seq data

Included in the Course

  • Course materials
  • Catering
  • Conference Dinner


  • Gero Doose (University of Leipzig) found and published several circularized RNAs in various RNA-Seq experiments. He specialized on split-read analysis some years ago and has a strong expertise in downstream analyses.
  • Dr. Christian Otto (CCR BioIT) is one of the developers of the split-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) works in the analysis of microarray data since 2007 and developed several bioinformatics tools such as the Bioconductor package AffyRNADegradation and the Larpack program package. Since 2011 he specialized in the field of HTS data analysis and helped analysing sequecing data of several large consortium projects.

What species will be used in this course?

ADD COMMENTlink written 5.5 years ago by daiefa123150

Hello daiefa123,

for the course we will use a full c. elegans genome and a real Illumina miSeq RNA-Seq sample. For the introduction part we decided to go for c. elegans, since read mapping is pretty time and memory consuming. The used genome and the miSeq run are small enough to use 'normal' machines (4 CPUs and 8GB RAM), without running out of memory and/or wait forever.

BUT: All tools, calls and pipelines can be used in exactly the same way for all other genomes, like human, bacteria, plants, etc.! (for some species some parameters should be adapted)

For the RNA-Seq part, we work with real human data, but limited the analysis to one chromosome. Again, the analysis can be done in exactly the same way for all chromosomes, you just have to wait a bit longer, if you have a weak machine.

I would be interested in your workshop,but I would like to ask you some questions about the RNA-seq part:

It will be used any R scripts or packages? It will be explained how to handle cufflinks and cuffdiff files for visualization (i.e heatmaps)?

Thank you
Alessio Stevano MSc

Dear Alessio Stevano,

for the isoform based differential expression we will explain and use the Tuxedo Suite (including cufflinks and cuffdiff) and R to visualize results from cummeRbund. For the gene and exon based DE, we will use DESeq and DEXSeq. We will also compare the results of all three (gene, exon and isoform based) DEs and show the differences.

I hope that answered your question.

Our Philosophy

  • Get trained by experts Our trainers have a proven record of academic and/or industrial experience in NGS data analysis. Because up-to-date expert knowledge is needed to answer your questions and know what is important in the field.
  • Open source NGS tools We only use open source tools that are free to use. We try to showcase and compare different tools (e.g. NGS mappers), since not every software fits with every task/question.
  • Learn effectively with well-curated materials For a optimal learning experience we carefully prepare our learning materials and example data. All materials, tools and results created during the course are for take home with you.
