  • In 2014 the NDAR infrastructure was expanded to include NDCT and RDoCdb, sharing data across the field of mental health. Although many of the functionality to work with the database is still operated through NDAR's original website, the NDA covers all domains.

Glossary

  • NDA is short for NIMH Data Archive. This umbrella organization includes a variety of repositories sharing data generated primarily by NIH/NIMH-funded research projects including NDCT, RDoCdb, NDAR, the ABCD Study, and much more.

  • Imaging+ is an NDA term which encompasses all imaging related data including, but not limited to, images (DTI, MRI, PET, Structural, Spectroscopy, etc.) as well as neurosignal data (EEG, fMRI, MEG, EGG, eye tracking, etc.) and Evaluated Data.

  • The National Database for Autism Research (NDAR) is an NIH-funded research data repository that aims to accelerate progress in autism spectrum disorder (ASD) research through data sharing, data harmonization, and the reporting of research results.

Filter Cart

The Filter Cart provides a way to query and access data for which you may be interested.  There are multiple places to go query and Add to Filter Cart (Sometimes called Download).  

A few points related to the filter cart are important to understand with the NDA Query/Filter implementation: 

First, the filter cart is populated asyncronously.  So, when you add subjects, sometimes it may take a few minutes to populate.  You can continue to do other things during this time. 

When you are adding your first filter, all data associated with your query will be added to the filter cart (whether it be a collection, a concept, a study, a data structure/elment or subjects). Not all data available for the subjects selected will necessarily be displayed.  For example, if you select the NDA imaging structure image03, and further restrict that query to scan_type fMRI, only fMRI images will appear and only the image03 structure will be available.  However, if you want to see all of the clinical and phenotype, then select, "Find All Subject Data" to see all the data avaialble for those subjects.  

when a secord or third filter is applied, an AND condition is used to determine the subjects that are exist in all filters.  If the subject does not appear in any filter, that subjects data will be excluded from your filter cart. Given the sparcity of data in the NDA, it is possible for no subjects to appear across filters.  If that happens, clear your filter cart, and start over.  

The NDA is looking to enhance query/filtering.  Until additional tools become available, it is best to package more data than you need and then package and download the data and use other tools to further restrict and analyze the data.  If you have any questions on data access, are interested in using avaialble web services or need help accessing data, please contact us for assistance.

Learn About NDAR

The NIMH Data Archive (NDA) is an infrastructure for sharing de-identified human subjects data with qualified researchers.  Data have been collected by hundreds of research projects across many scientific domains and harmonized to a common standard.  The NDA also provides tools, methods, and analysis capabilities enabling collaborative science and discovery.  Summary data is available to all.

The primary point of entry to the NDA is currently through the National Database for Autism Research (NDAR) website, which serves the autism research community.  All NDA repositories can be accessed through this website for data contribution and querying with other scientific communities, allowing for aggregation and secondary analysis of data.

*Imaging+ includes imaging data and all neurosignal recordings data (e.g., eye tracking, EEG, EGG, etc).
