Energy calculation at MRCI-F12 level of theory

[md alamgir]

Dear experts,

   I want to calculate single point energy at MRCI-F12 level of theory. I have written input file for this. But in output it is showing an error. Any kind of suggestion will be appreciated.

The input file:

geometry={-------

------------------------}

basis,vtz-f12

 {rhf;wf,symmetry=1,spin=0}


 {multi;
 occ,29,9;closed,25,2;
 wf,symmetry=1,spin=0;state,3;
 wf,symmetry=2,spin=0;state,1;
 natorb,ci,cprint}
   
 {mrci-F12; occ,29,9;core,25,2;
 wf,symmetry=1,spin=0;state,3}
   
 {mrci-F12; occ,29,9;core,25,2;
 wf,symmetry=2,spin=0;state,1}

The output:

---------------------------------------------------

 Using DEFAULT tuning parameter for mpplat   :    1000
 Using DEFAULT tuning parameter for mppspeed :      20
 Checking input...
