Filter Cart

The Filter Cart provides a powerful way to query and access data for which you may be interested.  

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 run a query, it may take a moment to populate but this will happen in the background so you can define other queries 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 structures or collections 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 shown.  To see other data structures, select "Find All Subject Data" which will query all data for those subjects. When a secord or third filter is applied, an AND condition is used.  A subject must exist in all filters.  If the subject does not appear in any one filter, that subjects data will not be included in your filter cart. If that happens, clear your filter cart, and start over.  

It is best to package more data than you need and access those data using other tools, independent of the NDA (e.g. miNDAR snapshot), to limit the data selected.  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.

NDAR provides a single access to de-identified autism research data. For permission to download data, you will need an NDAR account with approved access to NDAR or a connected repository (AGRE, IAN, or the ATP). For NDAR access, you need to be a research investigator sponsored by an NIH recognized institution with federal wide assurance. See Request Access for more information.

Selected Filters
No filters selected

The filters you have selected from various query interfaces will be stored here, in the 'Filter Cart'. The database will be queried using filters added to your 'Filter Cart', when multiple filters are defined, each will be executed using 'AND' logic, so with each filter that is applied the result set gets smaller.

From the 'Filter Cart' you can inspect each of the filters that have been defined, and you also have the option to remove filters. The 'Filter Cart' itself will display the number of filters applied along with the number of subjects that are identified by the combination of those filters. For example a GUID filter with two subjects, followed by a GUID filter for just one of those subjects would return only data for the subject that is in both GUID filters.

If you have a question about the filter cart, or underlying filters please contact the help desk at The NDA Help Desk

NIMH Data Archive (NDA) Data Dictionary

This page displays a list of all the structures currently supported in the NIMH Data Archive (NDA) Data Dictionary. Each structure represents a standardized definition of a measure that has been defined by researchers. On this list you can view:

  • Title: The name of the measure. This list is sorted alphabetically by title by default
  • Short Name: The NDA abbreviated ID for the structure
  • Shared Subjects: The number of unique subjects with shared data in this structure
  • Sources: Which NDA database(s) or federated systems include projects that have used this structure
  • Categories: The type of measure, relevant mental health issue, or other way of categorizing the structure
  • Submission: Some structures are obsolete, superseded by newer structures, or were created to support legacy projects. This column will display "Allowed" or "No" to indicate whether or not submissions of new data are currently accepted in this structure.

You can use the Search bar to filter the displayed structures based on category and title, or use the arrows in the header row to sort the current display based on that column. Once you’ve located a structure of interest, click on the title to enter the individual structure page.

You can use the check-boxes on the left to make selections and "Download" to add all data in those structures to your download cart. Please email the The NDA Help Desk with any questions.
