 Produce a regular `FCIDUMP` file from the |MOs| stored in the |EZFIO| 
 directory. 
  
 To specify an active space, the class of the |MOs| have to set in the 
 |EZFIO| directory (see :ref:`qp_set_mo_class`). 
  
 The :ref:`fcidump` program supports 3 types of |MO| classes : 
  
 * the *core* orbitals which are always doubly occupied in the 
   calculation 
  
 * the *deleted* orbitals that are never occupied in the calculation 
  
 * the *active* orbitals that are occupied with a varying number of 
   electrons
