# Interface: Topology window

The Topology Window is used for editing and viewing the topologies. A topology is a set of associations between racks and the locations they are in. This feature is provided so that runs can optionally put the racks in a specific configuration, rather than all runs using the same configuration.
The topology window is a list of all the topologies. To select one to edit or view, double-click on it. To make a new topology, click the "new" button and enter the name. The new topology will be a clone of the default topology to start with. There is always one topology called "default", representing the locations of the racks in the rack data window currently. The default topology can't be deleted. |
When you select a topology, a window like this one will appear. Here you can select the location for each rack and hit the "save" button to apply the changes. If you have placed more than one rack in a location, it will warn you of this fact. Also, you can add comments to topologies in this window just like in the rack data window. |
