     478==== Setup ==== 
     479 
     480Firstly `init_nemovar.sh` is run.  
     481Links are created to the ancillary files, the coordinates and the bathymetry.  
     482Additionally the `$DIR_INPUT` directory is created and the innovations, the assimilation background and the altimeter bias are linked into it.  
     483 
     484The namelist used is called `namelist.nemovar`. It is updated with the variable: 
     485{{{ 
     486nn_date0 "$(rose date -c -f %Y%m%d)" 
     487}}} 
     488 
     489The script then calls `run_nemovar.sh`.  
     490 
     491 
     492 
     493==== Run ==== 
     494 
     495 
     496==== Finalisation ==== 
     497 
     498If `run_nemovar.sh` completes succesfully then more steps in `init_nemovar.sh` are performed.  
     499The directory `$OUTDIR_INCREMENTS` is created and the increments produced in the NEMOVAR stage are combined into one file: 
     500{{{ 
     501rebuild_nemo increments_o01 ${NEMO_NPROC} 
     502mv increments_o01.nc ${OUTDIR_INCREMENTS}/assim_background_increments.nc 
     503}}} 
     504The same is also done for the altimeter bias (`altbias`).  
     505 
     506The file `assim_background_increments.nc` is one of the more important files; it contains the increments after each stage.  
     507These increments are applied to the background to create the analysis **x,,a,,**.
