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.

Visit for CNDA help documentation and videos, training schedules, rates and deployment schedules or email the CNDA help desk at

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