| The Change/Add Testing Data Window allows you to
            change the testing set (or add a new one) and gives access to the following
            settings and features:
               
            Add Data Source Icon 
            Opens the Data Source Dialog Box. 
             
            Remove Data Source Icon 
            Removes the data source. 
             
            Data Source Window 
            Shows the data source with its tables and columns. Columns and
            entire tables can be dragged and dropped onto the Testing Data
            Window below. 
             
            Add Column Icon 
            Adds a column selected from the Data Source Window above. 
             
            Remove Column Icon 
            Removes a selected column from the dataset. 
             
            Type Menu 
            Sets the type (input or predictable) of the selected column. You can
            also set the type through the mouse right-click. 
             
            Load Button 
            Loads/shows the selected columns' contents. 
             
            Clear Button 
            Removes all the columns from the Testing Data Window. 
             
            Testing
             Data Window 
            You prepare your testing data here by dragging and dropping the
            columns with your variables from the Data Source Window. You can
            also reorganize your dataset by moving a selected column up or down
            with the mouse. Your new testing set must have the same number of
            variables as the training set. If you want to change the number of
            variables, you must first change the training set. 
             
            Testing
             Data Table 
            Shows the loaded columns. GeneXproTools only shows 2048 columns on
            this table, but obviously loads them all, and you can see
            the exact number of loaded/shown columns on the status bar below. 
             
            Cancel Button 
            
            Cancels all the action on the replacement of the testing set. 
             
            Finish Button 
            
            Saves the new testing set.
