    11 As mentioned, the preprocessor is called before the WPS in each chunk. It must be an executable file that can be written in any language, and accepts 5 arguments. These are the `initial date`, the `end date` (as YYYY-mm-dd HH:MM:SS), the `input data path`, `member number` and `initialization month number` (4 and 5 arguments are available when `extdata_member` variable is used). After preprocessing, the preprocessor must copy the properly formatted input data to a folder called `WPS/grbdata`.

These are the `initial date`, the `end date` (as YYYY-mm-dd HH:MM:SS) and the `input data path`. If you want to add more arguments, you have to configure the `preprocessor_optargs` variable in the [wiki:WRF4G2.0/Experiment experiment.wrf4g] file. After preprocessing, the preprocessor must copy the properly formatted input data to a folder called `WPS/grbdata`.

    1313WRF4G provides some preprocessors as examples. These are located under `$WRF4G_DEPLOYMENT_DIR/repository/apps/preprocessor` directory. In order to create preprocessors, they have to be located in the `wrf4g_files/bin` directory of the specific experiment.
