+====Example: RMS of Metric====
+Here **Metric Root Mean Squared** is used along with **Metric Signal Value at Event** to find the RMS of the right ankle moment at heel strikes in a gait trial.
+First, define key gait events across files:
+<code>
+Automatic_Gait_Events
+! /FRAME_WINDOW=8
+! /USE_TPR=TRUE
+! /TPR_EVENT_INSTANCE=1
+;
+</code>
+Next, the right ankle moment at each heel strike is computed using **Metric Signal Value at Event** and the RMS of this metric is found for each trial:
+<code>
+Metric_Signal_Value_At_Event
+/SIGNAL_TYPES=LINK_MODEL_BASED
+/SIGNAL_FOLDER=ORIGINAL
+/SIGNAL_NAMES=RAnkleMoment
+! /RESULT_METRIC_FOLDER=PROCESSED
+/RESULT_METRIC_NAME=RAnkleMoment_HS
+! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=FALSE
+/SIGNAL_COMPONENTS=X
+! /COMPONENT_SEQUENCE=
+/EVENT_NAME=RHS
+! /EVENT_INSTANCE=0
+! /SCALE_FACTORS=1
+! /GENERATE_GLOBAL_MEAN_AND_STDDEV=TRUE
+! /GENERATE_LOCAL_MEAN_AND_STDDEV=TRUE
+! /APPEND_TO_EXISTING_VALUES=FALSE
+! /GENERATE_VECTOR_LENGTH_METRIC=FALSE
+! /RETAIN_NO_DATA_VALUES=FALSE
+;
+Metric_Root_Mean_Squared
+! /RESULT_METRIC_FOLDER=PROCESSED
+/RESULT_METRIC_NAME=RAnkelMoment_RMS
+! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=FALSE
+/SIGNAL_TYPES=METRIC
+/SIGNAL_FOLDER=PROCESSED
+/SIGNAL_NAMES=RAnkleMoment_HS
+! /COMPONENT_SEQUENCE=
+!/EVENT_SEQUENCE=
+/EXCLUDE_EVENTS=
+! /GENERATE_MEAN_AND_STDDEV=TRUE
+! /GENERATE_MEAN_AND_STDDEV_ACROSS_SUBJECTS=FALSE
+! /APPEND_TO_EXISTING_VALUES=FALSE
+;
+</code>
+Results:
+The resulting metrics can be found in the **METRIC:PROCESSED** folder.
