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.

bart_coefvarFloatRecommendedCoefficient of variation of adjusted pumps. This is the standard deviation of adjusted pumps divided by the mean adjusted pumps.
bart_coefvarredFloatRecommendedCoefficient of variation of adjusted pumps on the red balloons. This is the standard deviation of red adjusted pumps divided by the mean red adjusted pumps.
bart_coefvarblueFloatRecommendedCoefficient of variation of adjusted pumps on the blue balloons. This is the standard deviation of blue adjusted pumps divided by the mean blue adjusted pumps.
bart_cashoutwopumpFloatRecommendedThe number of times a participant cashed out of a trial without pumping. This can be used to exclude problematic cases.
oriballoonorderIntegerRecommendedOriginal balloon order. This is the original order that each balloon was presented (1 - 40). Because blue and red balloons are presented randomly to the participant, this variable retains the original order when the trials are re-organized by color.
balloonorderString20RecommendedThis variable organizes the balloon trials by order within each color (Blue 1-20 and Red 1-20), so that the investigator can see how pumping tendencies changed for each color across trials.
counttrialsIntegerRecommendedThis is the number of adjusted pumps for each trial.
explodetrialIntegerRecommendedThis is the number of pumps for each trial. When intersected with TOTALEXPLODEATTT= 1, then this value is the number of pumps on trials where the balloon DID explode. Otherwise, it's redundant with COUNTTRIALS (which is appropriately adjusted for the last press being a cash-out).

Data Structure

This page displays the data structure defined for the measure identified in the title and structure short name. The table below displays a list of data elements in this structure (also called variables) and the following information:

  • Element Name: This is the standard element name
  • Data Type: Which type of data this element is, e.g. String, Float, File location.
  • Size: If applicable, the character limit of this element
  • Required: This column displays whether the element is Required for valid submissions, Recommended for valid submissions, Conditional on other elements, or Optional
  • Description: A basic description
  • Value Range: Which values can appear validly in this element (case sensitive for strings)
  • Notes: Expanded description or notes on coding of values
  • Aliases: A list of currently supported Aliases (alternate element names)
  • For valid elements with shared data, on the far left is a Filter button you can use to view a summary of shared data for that element and apply a query filter to your Cart based on selected value ranges

At the top of this page you can also:

  • Use the search bar to filter the elements displayed. This will not filter on the Size of Required columns
  • Download a copy of this definition in CSV format
  • Download a blank CSV submission template prepopulated with the correct structure header rows ready to fill with subject records and upload

Please email the The NDA Help Desk with any questions.

Chart Help

Filters enable researchers to view the data shared in NDA before applying for access or for selecting specific data for download or NDA Study assignment. For those with access to NDA shared data, you may select specific values to be included by selecting an individual bar chart item or by selecting a range of values (e.g. interview_age) using the "Add Range" button. Note that not all elements have appropriately distinct values like comments and subjectkey and are not available for filtering. Additionally, item level detail is not always provided by the research community as indicated by the number of null values given.

Filters for multiple data elements within a structure are supported. Selections across multiple data structures will be supported in a future version of NDA.
