State Class

A fundamental building block of any state-and-transition model is the State Class. A State Class is comprised of a Class and a Subclass.

Creating a State Class

Step 1 - Create a Class and a Subclass

In ST-Sim, each State Class is defined by a unique combination of Class and Subclass values. So, to create a State Class you must first create at least one record in both the Class and Subclass Properties.

Step 2 - Create the State Class

Once you have created at least one Class and Subclass you are ready to create a State Class. State classes can be created manually by selecting a Class and a Subclass from the Class and Subclass combo boxes in the table. You can specify Name for your State Class, but if you leave this column blank a custom name will be generated for you. You can also create state classes directly in the transition pathway diagram, which will then be automatically added to the States table.

Additional Options

The following additional columns are available from the Context Menu.

Item	Description
ID	The ID for the State Class when running a spatially explicit simulation.
Color	The legend color for the State Class when displaying Spatial Maps. Double click in a cell to open the color editor and choose a color.
Map Legend	The map legend for the State Class when displaying Spatial Maps.
Description	A description of the State Class.

Remarks

The ID values for a State Class must correspond to the ID values for the State Class raster defined in the Spatial Initial Conditions Property.
