Neuroimaging Data Sharing& Software

NIACAL joins a national initiative to advance biomedical research through data sharing and online collaboration. To this end, we invite you to participate in our neuroimaging data sharing infrastructure outlined below. Visit our data portal tool to peruse what's available.

NUNDANorthwestern University Neuroimaging Data Archive (NUNDA)

We store much of our data in the Northwestern University Neuroimaging Data Archive (NUNDA). NUNDA is a resource for managing study data collected by the Northwestern University neuroimaging community. It includes a secure database, automated pipelines for processing managed data, and tools for exploring this data. Access to NUNDA is restricted to users authorized by the specific study's investigators.

Modeled after Washington University's CNDA, NUNDA can efficiently and securely store collected images of target brain structures in time-sensitive datasets. It is our hope that such datasets will serve as a source of images for pilot studies and support the educational programs of residency and fellowship training programs in neuroradiology, neurology, neurosurgery, and psychiatry.

NUNDA is powered by XNAT, an open source software platform designed to facilitate common management and productivity tasks for neuroimaging and associated data. For questions or more information, please contact

NUSDASTNorthwestern University Schizophrenia Data Sharing and Software Tool (NUSDAST)

The Northwestern University Schizophrenia Data and Software Tool (NUSDAST) is a database for sharing neuroimaging and related data with select collaborators or the general community. You can upload images, view them, add demographic and clinical data, and much more. The data are all stored in a searchable, secure web accessible database.

Accessing NUSDAST Data

  1. Obtain an account on XNAT Central
  2. Request access to NU Schizophrenia Data and Software Tool Federation using BIRN Infrastructure (NUSDAST) from XNAT Central account
  3. Sign the NUSDAST Data Use Agreement

Data Portal

To determine if our data can help your research, please visit our data portal tool and see what we have available. Guests can specify search parameters to isolate the data that meets their needs. Those with accounts on XNAT Central and access to the NUSDAST project will be able to download the data, as well.

Here are some tools we've developed in conjunction with our collaborators. Please contact with any questions or visit our wiki.

  • FS+LCDM Pipeline: An automated, FreeSurfer-initialized, labeled cortical distance mapping (LCDM) pipeline. FS+LCDM provides a probabilistic, local estimation of gray matter thickness of user-specified cortical structures from MRI brain scans. download
