-In a nutshell, queries sit in the following order of operations:
 Library → Query → Groups (which can contain multiple conditions) → Analysis

 In gait analysis, comparing knee joint angles across three walking speeds (SLOW, MEDIUM, FAST) might use three separate groups (one per speed condition). Each group would contain two conditions: left knee angle time-normalized from left heel strike (LHS)-LHS and right knee angle from right heel strike (RHS)-RHS, both refined by the appropriate speed tag. This structure enables direct comparison across speed conditions while properly handling bilateral symmetry within each condition.
-Group 1: KneeAngleX_SLOW

-  * LKneeAngleX, LHS-LHS, Refined by tag "SLOW"
-  * RKneeAngleX, RHS-RHS, Refined by tag "SLOW"
+Once queried your new groups will appear within the data tree on the Explore and Analyse pages like so:
-Group 2: KneeAngleX_MEDIUM
-  * LKneeAngleX, LHS-LHS, Refined by tag "MEDIUM"
-  * RKneeAngleX, RHS-RHS, Refined by tag "MEDIUM"
-Group 3: KneeAngleX_FAST
-  * LKneeAngleX, LHS-LHS, Refined by tag "FAST"
-  * RKneeAngleX, RHS-RHS, Refined by tag "FAST"
