How to use CHAINOP with your own MARS RDIR ?
=============================================

* If you want to point to your own MARS RDIR, change **runmars_dir** in section **directories**:

::

 [directories]
   #runmars_dir = '%(operational_dir)s/MARS/RUN_MARS/'
   runmars_dir = 'your_own_RDIR'


* In this case, you must copy:

  * your **paracom.txt** in **paracom.txt.ref**
  * your **paramain.txt** in **paramain.txt.ref**
  * your **output.dat** in **output.dat.ref**
  * your **paraspec.txt** in **paraspec.txt.ref** and **paraspec.txt.init** (if you plan to use option **--init**) 

* Because at each run, CHAINOP will systematically copy:

  * **paracom.txt.ref** in **paracom.txt**
  * **paramain.txt.ref** in **paramain.txt**
  * **output.dat.ref** in **output.dat**
  * **paraspec.txt.ref** or **paraspec.txt.init** (depending if you use option **--init** or not) in **paraspec.txt**

* In your own **inputs** directory (for example MARS/RUN_MARS/MANGAE2500/inputs), make links between forcing files (meteo, river, wave, obc) and files generated by operational chain. For example:

::

 mangae_meteo.nc -> ~/CHAINOP/inputs/MANGAE2500-r1630/meteo/mangae_meteo.nc
