Appendix 1: Input and Output

This appendix provides an overview of the input that is required by the SPHY model, and the output that can be reported by the SPHY model. It should be noted that the current version of the SPHY model GUI (version 1.0) does not support the interaction with all the input that can be specified in the SPHY model configuration file (*.cfg). This will be implemented in future versions of the GUI. Table 2 specifies the model input that can be specified in the current version of the SPHY model GUI. An overview of the output that can be reported by the model is shown in Table 3.
