Workshops are our most prolific (and popular) sources of presentations. Within the GATK Workshops directory, the directories containing workshop materials are grouped and organized by date, which is written as YYMM, so for example "1702" means "February 2017". To get the latest version of the workshop materials, just navigate to the directory with the largest number. In addition to the presentation slide decks, the workshop subdirectories typically also contain additional workshop materials such as tutorial datasets, worksheets and handouts. If you're interested in learning more about our workshop formula, see this article.
You are welcome to use any slides or figures featured in these slide decks for non-profit purposes as long as you provide clear attribution of their origin and a link to this website. We can provide high-resolution files on request. If you wish to use any slides or figures in a commercial publication or other such medium, or use our tutorial materials in a course, please post a request for permission in our support forum. This is mainly for tracking interest; we're happy to approve all reasonable requests.
Here are a few channels/playlists of GATK-related videos you may find useful. Note that some videos don't play when embedded, but if you click on the link to go to the playlist in YouTube they will play just fine.
