Starting A New Filter
The KBF program always has a current filter that is being modified. Thus, when creating a new filter, you must load an existing filter and save it under a different name that corresponds to the new filter. If you have a similar filter to the one you are creating, you should load that one, otherwise the filter defined in EXAMPLE.KBF is a good place to start. Save the new study after each of the steps listed below so that your work is backed up. The steps below are named by the window or command that they correspond to. It does not matter what order the steps are executed in. Once the steps are completed, the Fit command can be used to fit the filter to the data.

Notes Window
Modify the Notes window to contain a description of the new filter. The contents of this window are just comments and are intended to help you remember how the filter works. It is useful to include a definition for each of the components of the state and data vectors in this window.

Data Window
Create a new data file in which the line number corresponds to time index and column number corresponds to the component of the State Vector x . If you are going to simulate a data set, this file need only have one line. Change the file name following
     DATA VALUES 
in the Data window to the new data file. Also modify the bad data value, initial state estimate, covariance of the initial estimate, and the modulo values in the Data window.

Simulation Window
If you are going to simulate a data set, modify the Simulation window so that it returns state vector values corresponding to the new simulation. Then use the Compile command to link this simulation into KBF. Use the Simulation command to simulate the data set after the other steps below are completed and before you use the Fit command .

Measurement Window
Modify the Measurement window to contain the proper measurement model for the new filter. Then use the Compile command to link the new model into KBF.

Transition Window
Modify the Transition window to contain the proper Transition model for the new filter. Then use the Compile command to link the new model into KBF.

Plotting
Use the Plot command to delete, create or modify the plots and tables so that they are displayed for the new filter.
