 Separating configurations into multiple files can be useful if you want to compare different forecasts or observations in the same way. For example, to compare a different forecast to the observation in this example, copy GridStat_forecast.conf into a directory outside of the METplus repository (i.e. /home/user/METplus_user_config), rename it (i.e. GridStat_myforecast.conf), then change the values to match the new data set (input directory, input filename template, field name, etc.). Then you can run the new use case:
