 Once the model is compiled, make sure that XIOS=y in orchidee_ol.card.
 
-Moreover, new output files for ORCHIDEE have been specified within the code. If you are seeing the following error when you run:

-then it's possible you need to add lines in stomate.card, stomate.driver, sechiba.card, and sechiba.driver.  This is because the .xml files, when they have been copied to the working directory, cannot have values like "_AUTO_" in them.  libIGCM is supposed to replace such values, which exist in the template .xml files in modeles/ORCHIDEE/src_xml/, when it copies files from the run directory to the working directory.  If there is something missing in the .driver files, this replacement doesn't happen and XIOS throws the parsing error above.

 === Spin-up ===
-The analytical spin-up works with ORCHIDEE-CN-CAN. Note that irrespective of whether IMPOSE_CN is y or n, some carbon and nitrogen is put into the soil at the first time step (this is done in stomate_io.f90). Also, when IMPOSE_CN = n, N-deposition maps are being read adding N to the system. A model spin-up can start straight with impose_cn = n. If, after a test run, the equilibrium values are more or less known, the spin-up can be speed-up by setting in the run.def:
+The analytical spin-up works with ORCHIDEE-CN-CAN. To ensure growth at the onset of the analytic spin-up for all PFTs initial values are needed for the SOM pools, and that is  irrespective of whether IMPOSE_CN is y or n.

+The initial values of carbon for the four SOM pools are used globally. Sensitivity test have shown that the analytic spin-up is not sensitive to the actual size of the initial values. The different system will after a while settle in to there own state (N limited or saturated) in spite of having the same initial state.
