This command is found on the Insert tab of the ribbon bar, or in the Edit menu when using the toolbar and menu display.
This command creates a copy of the data source window, duplicating the properties of the active data source and its histograms, regions, and gates. This provides a convenient means of setting up for multiple file analysis and keeping the setup of each data source consistent with the one from which it was created. One common use for this is in histogram subtraction, where one file contains control data and another file contains test data.
The layout of histograms, regions, and gates are replicated in the new data source window.
