    21 After the adaption of the parallelization, the initialization of PDAF has to be implemented. It is performed by the routine `PDAF_init`. This subroutine has several arguments. Typically, the initializations of all variables required for the call to `PDAF_init` can be collected into a single subroutine. This implementation strategy is useful, as only a single additional subroutine call has to be inserted to the model source code. In the example in `testsuite/src/dummymodel_1D` the routine in the file `init_pdaf.F90` collects all initializations for PDAF. Likewise the tutorial implementations use a routine `init_pdaf.F90`. The file `init_pdaf.F90` in `templates/` provides a commented template for this routine, which can be used as the basis of the implementation.

    2323`PDAF_init` itself calls a user-supplied routine to initialize the ensemble of model states through its interface. In the example there are separate routines for ensemble-based and mode-based filters. They are in the files `init_seik_pdaf.F90` (for SEIK, LSEIK, ETKF, LETKF), `init_enkf_pdaf.F90` (for EnKF), and `init_seek_pdaf.F90` (for SEEK).
