Announcing the 2017 XNAT Developer Workshop

We are happy to announce that the 2017 XNAT Developer Workshop will take place in Rotterdam, the Netherlands from October 16th until October 18th. The workshop is organized jointly by the Erasmus Medical Center, Rotterdam and Washington University in Saint Louis and is sponsored by the BBMRI-NL2.0 project.

The workshop will feature speakers from the XNAT development team and will focus on open source XNAT development, including creating XNAT plugins, coding with the XNAT API, integrating external applications, and writing analysis pipelines. The program will be organized around hands on sessions in which attendees can work on their own projects or join collaborative efforts with other attendees.

We hope you will be able to join us in Rotterdam for the workshop.  A 250 euro attendance fee includes daily lunches and a social dinner on the first night. Please visit the event wiki page for more information and to register for the event.

Best regards,

Day 2: Oct 17, 2017

XNAT Plugin Development, XNAT Core Development and Customizations, and Working Project Groups

The best way to add functionality to an XNAT 1.7 instance is to build and install a plugin. We'll walk you through the process of coding and building a plugin. A separate group will walk through setting up a core XNAT development environment, for those occasions when support for new functionality needs to be added to core XNAT. Later in the day, developers will pair off into working groups to advance their projects.

Guided working sessions will be offered each afternoon to help attendees develop their project ideas. Members of the workshop team will be available as needed to help. There is a list of hackathon projects where you add yourself to a project or propose new projects.



To register please visit the registration form. The cost of the workshop is 250 euros, this includes daily lunch and the group dinner on the first night. Due to the size of the venue there is a maximum number of attendees, and while we do not expect this to be a problem it might be possible that the registration closes at some point.


The workshop will be hosted at CIC Rotterdam, which is a flexible co-working space located right next to Rotterdam Central station. A list of nearby hotels can be viewed here at google maps.

Rotterdam has its own Rotterdam airport (airport code RTM) with some European destinations. Rotterdam also good train connection (25 minutes, direct train) to Schiphol Amsterdam Airport (airport code AMS). There are many national train connections serviced by the Dutch Railways and there is also an international high-speed train service to Antwerp, Brussels and Paris operated by the Dutch Railways International.

Technical Requirements

To participate in practical XNAT development sessions, attendees are expected to bring a sufficiently powered laptop to run XNAT virtual machines. There will be wi-fi connections available in the conference center, but users are also strongly encouraged to download necessary components prior to the start of the Workshop to minimize delays and setup time.  Please contact us if you have questions about the required hardware.
