Variant analysis with GATK

Date: 14.05.2019 9:00 - 17.05.2019 17:00
Location details: The lecture day 14.5 is organised in Haartman Institute in Lecture hall (luentosali) 2 at Haartmaninkatu 3. The hands-on days 15.-17.5 take place in the computer classroom Dogmi at CSC at Keilaranta 14, Espoo. The best way to reach us is by public transportation; more detailed travel tips are available.
Language: English
Lecturers: GATK Team
Price: The registration fee is 60 euros + VAT per day. The fee covers morning and afternoon coffees . Students from Integrative Life Science (ILS) doctoral program can register for free
Registration by 30.04.2019 16:00
The seats are filled in the registration order. If a cancellation is received five (5) business days prior to the course, the course fee will be refunded with the exception of a handling fee of 10 €. For no-shows and cancellations after that no refunds will be made. Registration can be transferred to someone else from the same organization without additional charge.

Payment can be made with electronic invoicing, credit card, or direct bank transfer. Note that for electronic invoicing you need the operator and e-invoicing address (OVT code) of your organization. Please also note that invoice reference is needed for electronic invoicing in your organization, so please have this available when registering.

This workshop will focuss on the core steps involved in calling variants with the Broad Institute's Genome Analysis Toolkit (GATK), using the "Best Practices" developed by the GATK team. You will learn why each step is essential to the variant discovery process, what are the operations performed on the data at each step, and how to use the GATK tools to get the most accurate and reliable results out of your dataset. This course is organized in collaboration with Doc­toral Pro­gramme in In­teg­rat­ive Life Science (ILS)  of University of Helsinki.

This workshop highlights key functionalities such as the germline GVCF workflow for joint variant discovery in cohorts, RNAseq­ specific processing, and new somatic variant discovery capabilities in GATK4. It also mentions the use of pipelining tools to assemble and execute GATK workflows.

Please note that this workshop is focused on human data analysis. The majority of the materials presented does apply equally to non­human data, and we will address some questions regarding adaptations that are needed for analysis of non­-human data, but we will not go into much detail on those points.

Target audience and prerequisites

The lecture day of the workshop is aimed at a mixed audience of people who are new to the topic of variant discovery or to GATK, seeking an introductory course into the tools, or who are already GATK users seeking to improve their understanding of and proficiency with the tools. Attendees should already be familiar with the basic terms and concepts of genetics and genomics.

The hands-on days are aimed at novice to intermediate users who are seeking detailed guidance with GATK and related tools. Basic familiarity with the command line environment is required.

Learning objectives

After this course you should be able to:

  • Understand the overall variant discovery workflow rationale and requirements

  • Understand key methods and functionalities in light of the latest research

  • Understand key differences between germline and somatic variant discovery approaches

  • Apply analysis tools and Best Practices workflows to a real data set

  • Interpret analysis results and troubleshoot common problems
