 Here we override the default values that are set in the flowchart. 
 The `input_footprint` and `input_pointcloud` are passed directly in the command line.
-In addition, the `input_footprint_select=47` (to select the 47th feature from the input footprint file) is read from the config file `config.toml`.
+In addition, the `input_footprint_select_sql='fid=47'` (to select the 47th feature from the input footprint file) is read from the config file `config.toml`.
 
 Combining the command line parameters and the config file allows you to keep the parameters that don't change with each model in the configuration file, while passing input and output parameters in the command line.
