      - regrids fluxes (fluxes need to be at the same spatial 
        resolution as the flexpart grid_time files)
      - writes fluxes in a standard ncdf format required by
-       FLEXINVERT
+       FLEXINVERT-Plus
   3) prep_regions (optional):
      - prepares variable resolution grid for the inversion based 
        on flexpart flux sensitivities (output from prep_flexpart)
        (alternatively can provide own regions definition file)
   4) settings:
      - contains example SETTINGS_config and SETTINGS_files files
-       for FLEXINVERT
+       for FLEXINVERT-Plus
   5) source:
-     - source code for FLEXINVERT
+     - source code for FLEXINVERT-Plus
+  6) prep_syndata:
+     - prepares synthetic data for testing and OSEs
+     - uses output from a forward run and adds random
+       perturbations to the prior fluxes and observations
+       according to the error covariance matrices
+  7) grid_to_ncdf:
+     - extra tool (not needed for FLEXINVERT-Plus) to convert
+       the binary grid_time files to NetCDF
   
 Testing environment:
   Basic test data are provided for four example cases, for both
