    v6 v7  
    3232  * 100: GENOBS (generate synthetic observations)
    3333  * 200: 3D-Var
    34  * `subtype`: An integer defining the sub-type of the filter algorithm (see the example code in `testsuite/src/dummymodel_1D` for choices). If `PDAF_init` is called with `subtype=-1` the available options are shown for the selected filter algorithm.
     34 * `subtype`: An integer defining the sub-type of the filter algorithm (see the example code in `templates/online_omi/init_pdaf.F90` for choices). If `PDAF_init` is called with `subtype=-1` the available options are shown for the selected filter algorithm.
    3535 * `step_null`: An integer defining the initial time step. For some cases it can use useful to set `step_null` larger to 0.
    3636 * `filter_param_i`: Integer array collecting several variables for PDAF. The first two variables are mandatory and equal for all filters. Further variables are optional (see example code or use `subtype=-1` to display available options.). The mandatory variables are in the following order:
     
    3838  * The ensemble size for all ensemble-based filters (or the rank of the state covariance matrix for mode-based filters like SEEK)
    3939 * `length_filter_param_i`: An Integer defining the length of the array `filter_param_i`. The entries in the array are parsed up to this index.
    40  * `filter_param_r`: Array of reals collecting floating point variables for PDAF. The first variable is mandatory and equal for all filters.  Further variables are optional (see example code in `testsuite/src/dummymodel_1D` or use `subtype=-1` to display available options.). The mandatory variable is:
     40 * `filter_param_r`: Array of reals collecting floating point variables for PDAF. The first variable is mandatory and equal for all filters.  Further variables are optional (see example code in `templates/online_omi/init_pdaf.F90` or use `subtype=-1` to display available options.). The mandatory variable is:
    4141  * The value of the forgetting factor controlling covariance inflation (required to be larger than zero; common are values between 0.9 and 1.0. For 1.0 the ensemble is not inflated.)
    4242 * `length_filter_param_r`: An Integer defining the length of the array `filter_param_r`. The entries in the array are parsed up to this index.
