Usage Scenario

This Step sorts and labels data by values. It is usually used with Validate Labels and Output Flags to filter the data list by value intervals. If you need to divide the data list into two parts by a threshold and filter out one of them, please use Dichotomize Values by Threshold together with Filter instead.

Parameter Description

File Settings

Threshold File Name
