+====== Query ======
+In Visual3D, Sift, and Inspect3D, a query is a way to select a subset of files or signals based on user-defined criteria.
+==== Query Parameter in Visual3D ====
+Several commands in Visual3D have the Query parameter, which allows users to select a subset of files based on data within the files. A query allows users to reference the data table to set a file as active. If the expression is true, that file will be set to active. If the expression is false, the file will not be set as active.
+Expressions can be used as part of queries as they are found [[Visual3D:Documentation:Pipeline:Expressions:Expressions_Overview|here]].\\
+**Example:**
+<code>
+Select_Active_File
+/FILE_NAME=ALL_FILES
+/QUERY=METRIC::PROCESSED::RKNEE_MAX::X > 70
+;
+</code>
+The above will set any C3D files that the specified value is above 70. The value (METRIC::PROCESSED::RKNEE_MAX::X) must be previously created.
+==== Queries in Inspect3D and Sift ====
+Inspect3D and Sift use queries to select specific signals are from the current [[Visual3D:Documentation:Definitions:CMO_Library_|CMO Library]]. Queries correspond to groups and each query contains an arbitrary number (1-n) of Definitions, which correspond to the group's sub-groups. Signals in these sub-groups can be selected or not selected based on further refinements and time-normalized based on user-specified events. See Inspect3D's [[Other:Inspect3D:Documentation:Dialogs:Advanced_Query_Section|Group Definition]] dialog or Sift's [[Sift:Application:Query_Builder_Dialog|Query builder dialog]] and [sift:documentation:group|groups definitions] for more information.
+It is possible to save Inspect3D and Sift queries to a [[Other:Inspect3D:Documentation:Files:Q3D_Query_File|.q3d file]] for easy reuse during future analysis.
