Neuroimaging Data Sharing& Software
NIACAL joins a national initiative to advance biomedical research through data sharing and online collaboration. To this end, we have created SchizConnect, a large-scale data sharing infrastuctue. We share our Northwestern University Schizophrenia Data and Software Tool (NUSDAST) data on SchizConnect.
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 NUNDA_Admin@northwestern.edu.
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.
You can search and download NUSDAST data (along with data from other sites) on SchizConnect (schizconnect.org).
Below are some tools we've developed in conjunction with our collaborators. Please contact with any questions.
- BYU Surface Splitting: Scripts to split HiAm and basalth byu surfaces into components. See split_surfaces_NUSDAST.sh for example usage. The binary has been compiled as a static binary in hopes that it will run cross-platform, but src is also included. download
- 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
