+### 9. Use CDORemap() in function
+
+If you want to interpolate data by s2dverification::CDORemap in function, you need to tell the
+machine which CDO module to use. Therefore, `CDO_module = 'CDO/1.9.5-foss-2018b'` should be 
+added in Compute() cluster list. See the example in usecase [ex2_3_cdo.R](inst/doc/usecase/ex2_3_cdo.R).
