The purpose of this workshop is to get a deeper understanding in Next-Generation Sequencing (NGS) with a special focus on bioinformatics issues. Advantages and disadvantages of current sequencing technologies and their implications on data analysis will be discovered. The participants will be trained on understanding their own NGS data, finding potential problems/errors therein and finally perform their first downstream analysis (variant calling). In the course we will use a real-life NGS dataset from the current market leader illumina.

All workshop attendees will be enabled to perform important first tasks of NGS data analysis themselves. The course layout has been adapted to the needs of beginners in the field of NGS bioinformatics and allows scientists with no or little background in computer science to get a first hands-on experience in this fast evolving research topic.

The online course will make use of a web conferencing system. Hands-on NGS analysis will be performed in an interactive browser-based platform. Before the course, you will get a printed manuscript and a USB key by mail.

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.

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. NGS Technologies:
    Different methods of NGS will be explained and compared, together with the consequences for data analysis. The most important notations and an overview over various applications will be given.
  2. Practical Bioinformatics (with Linux):
    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.
  3. Introduction to NGS data analysis:
    Important first NGS analyses tasks will be explained and performed. This module covers essential knowledge for analysing data of different NGS applications.

Dr. David Langenberger (ecSeq Bioinformatics GmbH)
David started working with small non-coding RNAs in 2006. Since 2009 he uses NGS technologies to investigate these short regulatory RNAs as well as other targets. He has been part of several large NGS projects, for example the International Cancer Genome Consortium (ICGC).

Dr. Mario Fasold (ecSeq Bioinformatics GmbH)
Mario 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 NGS data analysis and helped analysing sequencing data of several large consortium projects.


The target audience is biologists or data analysts with no or little experience in analyzing NGS data. A fundamental understanding of molecular biology (DNA, RNA, gene expression, PCR, ...) is assumed.

A basic knowledge of Linux & Bioinformatics (commandline usage, common commands and tools) is beneficial, but not required.

A current desktop computer / laptop with an up-to-date browser (Firefox or Chrome) is required.

  •   Printed course materials
  •   High-performance cloud computer (accessed via browser)
  •   Bootable USB-Stick for seamless continuation / repetition after the course

  •   Hands-on use of essential NGS tools to see where the stumbling blocks are
  •   Our assistants can help you and provide feedback you on the spot
  •   No previous installation of software necessary
  •   Discussion rounds with the possibility to ask questions at the end of each session
  •   Continue practicing on your own using our bootable USB-Drive and the printed manuscript

"Thoroughly enjoyed the NSG course in Munich. The course was very comprehensive, professionally delivered, and completely met both my requirements and expectations. A lovely touch was the social networking aspect delivered by fantastic lunchtime meals in a lovely nearby restaurant, as well as an evening meal in a stunning historic bistro. I can't wait to book my next course!" Roxane Dunbar, Plymouth University, UK

"I attended the course: Next-Generation Sequencing Data Analysis: A Practical Introduction”. It is one of the best workshops I ever attended. The organization, quality and course material was just great. The small excercises during the workshop were useful to internalize the contents. It was fairly easy to follow even if one has not worked with linux before. The trainers were open to all questions and took their time for all requests. I would strongly recommend the workshop!" Sophie Bartsch, Fraunhofer Institute for Cell Therapy and Immunology, Germany

"This introductory course on Next Generation Sequencing (NGS) by ecSeq was amazing, even for someone with no prior Linux/Unix experience. they explained everything from the basics down to the higher details about how each program actually works, on such an understandable level. I would recommend this course to anyone needing a good start in sequencing and large scale bioinformatics. Kind and helpful people, useful information and just a great course" Robin Lawder, University Munich, Germany

When you register for this workshop you are agreeing with our Workshop Terms and Conditions. Please read them before you register.


What you need:

  • A computer with one of the following operatins systems: Windows 7 or later (incl. Windows 10), Mac OS X 10.13 or later.
  • One of the following web browsers: Edge 42 and later, Chrome 65 or Later, Firefox 48 or Later.
  • A microphone and loudspeakers/headphones.

  The course cannot be run on phones, tablets and similar handheld devices.


We will start every morning at 8am (CDT) sharp and work together until 4pm (CDT) in the afternoon. There will be regular short breaks and a longer break at lunchtime.

As this is a live broadcast, you cannot pause the course and continue later. The individual exercises build on each other, so you should not leave in between.


No, you do not have to install any software to follow the course. You will get access to a high performance computer in the cloud, which you can easily log into using an in-browser console. All necessary programs are already installed on this computer. This way, we can start right away.


Of course we'll help you. If such a case should occur, we have assistants whom you can contact via chat. They can dial into your in-browser console and see exactly the same as what you see. This way they can help you directly and without much detour.

Note: The assistent can only see your in-browser terminal window but nothing else and also do not have any access to your computer.


A few days before the course we will send you a manuscript and a USB stick by mail. The USB stick is bootable and contains a copy of the Linux distribution we will use in the course. If you insert this stick into your computer and boot from it, a live version of Linux will be running on your computer where you can repeat and/or practice all the tasks of the course.


We have tried to keep the differences between the online and the attendance courses as small as possible.

Before the event: If you like to travel and get to know new cities, you will miss that in an online course. But, with an online workshop, you will obviously have to organise and plan much less. Travel and accommodation are not necessary. Likewise, you will not have any lost days of arrival and departure.

During the event: Unfortunately, due to the limited possibilities online, there will be no major discussions or interactive sessions. Likewise, the possibilities for networking (e.g. during the conference dinner) are unfortunately very limited. But of course we will answer your questions online as well. You can raise your hand at any time and we will activate your microphone.
