Updates on Java Applets
  • Chrome Browser: Java applets will no longer be supported as of September 2015

  • Edge Browser: Edge will be the default browser in Windows 10. It does not support Java applets.

  • The CNDA's Uploader Applet, ImageJ-based Image Viewer, and Download Images (dir) tools are all Java applets. If you use these tools, you will need to make sure you access the CNDA via a browser with support for Java applets.

Please contact the CNDA Help Desk with any questions or concerns.
What is the CNDA?
The Central Neuroimaging Data Archive (CNDA) is a resource for managing study data collected by the Washington University neuroimaging community. It includes a secure database, automated pipelines for processing managed data, and tools for exploring and accessing the data. Access to data in the CNDA is restricted to users authorized by the specific study’s investigators. The CNDA is hosted by the Neuroinformatics Research Group.

The CNDA is powered by XNAT, an open source software package for managing neuroimaging and related data.
