By double-clicking on the AUSRIVAS icon, (either in Explorer on the Desktop if you have set up a shortcut) the AUSRIVAS program will open. It has a series of labelled overlying sheets with menus and a toolbar across the top of the page and a status indicator at the base.

The first sheet is for the entry of invertebrate data, the second sheet for entry of habitat data. The remaining sheets will contain various outputs from the model once it has been run. The complete list of data sheets is:

1.        Bug Data - This is where you enter your invertebrate data.

2.        Phys/Chem Data - This is where you enter your predictor variables.

3.        Group Probabilities - Shows group probabilities after a model has been run.

4.        Taxon Probabilities - Shows taxon probabilities after a model has been run.

5.        Predicted/Collected - Shows output statistics after a model has been run.

6.        Unused Bugs - The taxa that were not used when the model was run are moved to this sheet.

The toolbar includes some standard Microsoft Windows menu items along with a few new ones for importing and exporting text format data.
