/path/to/lrose/install/bin/Colide -print_params > param_file_name
If you already have a parameter file and simply want to check for (and add) updated parameters while retaining current parameters, use the following command:
/path/to/lrose/install/bin/Colide -params orig_param_file_name -print_params > new_param_file_name
