. What are predefined filter queries? A predefined filter query enables users to select and define categories of data they want related to relevant subjects. These filters are displayed as checkable boxes to select items to query. This includes the ability to query by sub-sets of connections based on experimental conditions or other parameters. This way, data is narrowed down to include the concepts of most interest. Can new queries be added to existing models? Yes, NDA provides a way to add predefined filters. If the data are present a predefined filter can be created. Contact the NDA Help Desk for more information on how to add queries for data that interests you.
