# Subsystem Editor Window

The Subsystem Editor is displayed only if you select a subsystem-specfic algorithm from the Algorithm Editor and select Ok or if you double-click on a subsystem-specfic algorithm, or its subsystems, from the Regression Test Editor.

The window displays the current algorithm you are selecting subsystems for. Only the subsystems selected with a pass or fail result will be added to the Regression Test Editor. Like the Algorithm Editor, the Subsystem Editor will populate itself with the algorithm's assigned subsystems. Subsystems can be removed by unchecking them from the Subsystem Editor or by using the Remove Algorithm option. If you choose to remove a subsystem-specific algorithm from a project, all subsystems associated with the algorithm will also be removed.
