  * At the beginning of the program, the routine `init_parallel_pdaf` is executed. `init_parallel_pdaf` creates the parallel environment for PDAF. In the offline mode, it is possible to execute the assimilation program on a single processor, even if the model is parallelized. 
  * Subsequently, a routine `init_pdaf` is executed. In this routine, parameters for PDAF can be defined and then the core initialization routine `PDAF_init` is called. This core routine also initializes the array of ensemble states. In case of the offline mode, this means that the ensemble is read from the output files of the model.
- * Finally, the PDAF core routine `PDAF_put_state` is executed. As for the offline mode there is no ensemble integration in the assimilation program, this subroutine directly computes the analysis step (i.e. the actual assimilation of the observations). In a user-supplied subroutine of `PDAF_put_state`, the ensemble of analysis states is finally written into restart files for the next forecast phase conducted by direct model integrations initialized from these files.
+ * Finally, the routine `assimilation_pdaf` is call. In this routine, the names of the user-supplied routines are declared and than the filter-specific PDAF core routine `PDAF_put_state_X` is executed (where X is replaced by the name of the filter algorithm, e..g X=estkf). As for the offline mode there is no ensemble integration in the assimilation program, this subroutine directly computes the analysis step (i.e. the actual assimilation of the observations). In a user-supplied subroutine of `PDAF_put_state`, the ensemble of analysis states is finally written into restart files for the next forecast phase conducted by direct model integrations initialized from these files.
