 '''Now you can run 2 to 10 years of LMDZOR'''
 
-* Create a coupler restart file `flxat.nc` using the end of the LMDZOR run
-
-You will need to download and install 
+* Create a coupler restart file `flxat.nc` using the end of the previous LMDZOR run
+You will need to download and run the [wiki:Doc/Tools#CPLRESTART CPLRESTART] tools.
+
+In some working directory download the CPLRESTART tools from the "IPSL forge" svn repository with:
+{{{
+svn co http://forge.ipsl.jussieu.fr/igcmg/svn/TOOLS/CPLRESTART .
+}}}
+
+This will create a CPLRESTART directory.
+Use `CreateRestartAtm4Oasis.bash` shell script to create the `flxat.nc` file from the `histmth.nc` file for the last year or your previous LMDZOR run.
+{{{
+CreateRestartAtm4Oasis.bash --oce ORCA2.3 $PATHTOFILE/LMDZOR_18690101_18691231_1M_histmth.nc
+}}}
+
+The `--oce ORCA2.3` will just write some information in the `flxat` file and name it accordingly to help you remember the origin of this file.
+You may need to adjust the modules loaded to make the shell script and its associated python script `create_flxat.py` work on your machine:
+{{{
+    module purge           # works on irene skl with redhat 7
+    module load hdf5
+    module load netcdf-c
+    module load nco/4.9.1
+    module load cdo/1.9.5
+    module load python3/3.7.2
+    module load datadir/igcmg
+    module list
+}}}
+
+* You can now run your MOSAIX simulation
+Fill your config.card in order to: 
+ ** restart all the oceanic components from the MOSAIC coupled simulation
+ ** restart the atmosphere and vegetation components from the LMDZOR forced simulation
+ ** restart the coupler from initial state files:
+{{{
+#========================================================================
+#D-- Restarts -
+[Restarts]
+
+...
+
+#========================================================================
+#D-- CPL -
+[CPL]
+WriteFrequency="1M"
+# If config_Restarts_OverRule == 'n' next 4 params are read
+Restart= n
+...
+
+}}}
+
+Lastly, modify the `COMP/oasis.card` file to get the initial files for the coupler:
+{{{
+[InitialStateFiles]
+List=   (/ccc/work/cont003/gen2212/nguyens/PALEO/CPLRESTART/PIMX/flxat_LMD9695_maskFrom_ORCA2.3.nc, flxat.nc), \
+        (${R_IN}/RESTART/IPSLCM5A2/PROD/piControl/CM5A2.1.pi.debug/CPL/Restart/CM5A2.1.pi.debug_50091231_sstoc.nc, sstoc.nc)
+}}}
+'''You can now run your MOSAIX coupled simulation extending the previous MOSAIC one'''
