+====== Metric Median ======
+This command computes the Median Value of a Signal and store the value as a metric
+=====Command Syntax=====
+The syntax for the function is as follows:
+<code>
+Metric_Median
+! /RESULT_METRIC_FOLDER=PROCESSED
+/RESULT_METRIC_NAME=
+! /APPLY_AS_SUFFIX_TO_SIGNAL_NAME=FALSE
+/SIGNAL_TYPES=
+! /SIGNAL_FOLDER=ORIGINAL
+! /SIGNAL_NAMES=
+! /COMPONENT_SEQUENCE=
+/EVENT_SEQUENCE=
+/EXCLUDE_EVENTS=
+! /GENERATE_MEAN_AND_STDDEV=TRUE
+! /APPEND_TO_EXISTING_VALUES=FALSE
+;
+</code>
+=====Parameters=====

+=====Example=====
+In the following example, compute the Median Value of the signal HANDSPEED:
+<code>
+Metric_Median
+/RESULT_METRIC_NAME=_MEDIAN
+/APPLY_AS_SUFFIX_TO_SIGNAL_NAME=True
+/RESULT_METRIC_FOLDER=PROCESSED
+/SIGNAL_TYPES=DERIVED
+/SIGNAL_NAMES=HANDSPEED
+/SIGNAL_FOLDER=PROCESSED
+/SIGNAL_COMPONENTS=ALL_COMPONENTS
+/EVENT_SEQUENCE= FRAME1 + GO
+/EXCLUDE_EVENTS=MAX_SPEED
+/SEQUENCE_PERCENT_START=
+/SEQUENCE_PERCENT_END]]=
+/GENERATE_MEAN_AND_STDDEV=TRUE
+/APPEND_TO_EXISTING_VALUES==FALSE
+;
+</code>
+NOTE: When you run a metric command, and tell it to create a global mean, it uses all the individual ranges to compute the overall mean (ie; one trial has 4 ranges, second trial has 1 range, the global mean is generated from the 5 values).
+If you want each trial to have a median, and then create a median of those medians, you need to run a second command for metric median on the result of the first commands _median. (ie; One trial has 4 ranges, second trial has 1 range. The command will create a median in each trial containing an overall median for the trial, the global median would be the median of the medians).
