 To perform a twin experiment using the synthetic observations generated by PDAF, one runs the data assimilation as one would with real observations. If one already initializes the vector of actual observations in the routine `init_dim_obs_f` one only needs to small modification of this routine. Namely, only required modification is that at the end of `init_dim_obs_f` one overwrites the vector of real observations with the values from the synthetic observations. If one uses the template file `readwrite_obs.F90` for this, one can use `read_syn_obs` from this file at the end of `init_dim_obs_f` to overwrite the observatio vector. To allow for a flexible switching between the case using real observations and the twin experiment, one can for example introduce a flag `twin_experiment` that controls whether the real observation values are overwritten.
 
-Example implementations using `PDAF_put_state_generate_obs` and `readwrite_obs.F90` are provided by the two test cases `testsuite/src/dummymodel_1D` and `testsuite/src/lorenz96`. These also use the flag `twin_experiment` to actiavate the twin experiment (Note: These two test cases always use simulated observations. Nonetheless, they allow to see how the synthetic observations are generated with PDAF and how they are used in a twin experiment).
