 ====== Excluding Data in Sift ======
-In biomechanics, some trials or trace may not be suitable for analysis. A missed marker, an incorrect force plate assignment, or an unexpected movement during a trial can all introduce noise into the results. Rather than deleting these trials outright, Sift allows users to flag them for exclusion, which keeps the analysis clean while preserving the original data.

 Data cleaning is an ongoing process, and exclusions can be revisited at any time as new issues are identified.

 ===== How Exclusions Work =====
-Excluding a trace removes it from analysis (and optionally, plots), but does not delete the underlying data. Exclusions can be undone at any time using Ctrl+Z or by right-clicking a workspace and selecting Re-Include Data, and excluded traces can be toggled back on to review them alongside valid data.
+Excluding a trace removes it from analysis (and optionally, plots), but does not delete the underlying data. Exclusions can be undone at any time using Ctrl+Z or by right-clicking a workspace and selecting Re-Include Data, and visibility of excluded traces can be toggled back on to review them alongside valid data.
 Sift supports three levels of exclusion:
   * **Individual trace**: exclude a single signal cycle only
+{{:sift:application:individual_trace_exclusion.png?400|Individual trace exclusion}}
   * **All traces at those frames**: exclude all queried signals during the same cycle
+{{:sift:application:traces_at_frames_exclusion.png?400|Exclude traces by frames}}
   * **Entire trial**: exclude all data from the affected trial
+{{:sift:application:entire_trial_exclusion.png?400|Exclude entire trial}}
