XNAT is an open source imaging informatics platform developed by the Neuroinformatics Research Group at Washington University. It facilitates common management, productivity, and quality assurance tasks for imaging and associated data. XNAT can be used to support a wide range of neuro/medical imaging-based projects.

Command(s) provided by this extension

  • xnat-init -- Initialize an existing dataset to track an XNAT project
  • xnat-update -- Update an existing dataset of an XNAT project; retrieve data from the tracked project
  • xnat-query-files -- Query available files on an XNAT instance or project
