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).
