My original input is for the orca job was:

! UKS BP SP PBE0 D3BJ ZORA ZORA-def2-SVP Sarc/J FinalGrid6 TightSCF RIJCOSX CPCM(Acetonitrile)
%maxcore 2000
%pal
nprocs 12
end
%tddft
    maxdim 10
      nroots 300
        DoNTO true
end
%scf
    MaxIter 500
end
%basis Newgto 58 "SARC-ZORA-TZVPP" end
       Newauxgto 58 "Sarc/J" end
       Newgto 16 "ZORA-def2-TZVPP" end
       Newauxgto 16 "Sarc/J" end
       Newgto 8 "ZORA-def2-TZVPP" end
       Newauxgto 8 "Sarc/J" end
end
%output
    Print[P_ReducedOrbPopMO_L] 1;
    Print[P_FragPopMO_L] 1;
end

do you recommend that i rerun using a tight print or is finalgrid6 enough?

Dear Multiwfn users.

I am still relatively new to orca and am struggling to figure out how to get orca to generate common output files. Currently, I am trying to figure out how to generate excited state .wfn file to use in Multiwfn charge-transfer analysis based on electron density differences (Multiwfn section 4.18.3). The orca_2aim program takes the electron density from the .gbw file and replots as a .wfn. This makes it trivial to generate ground state .wfn file.

My issue is in finding a way to generate the excited state .gbw fill which can be converted to a .wfn from an existing TDDFT calculation? This was simple in Gaussian09 using TD(read, root=#, NonEqSolv) with the Dencity=Current and out=wfn but i can not find the equivalent operation in the orca manual. Does anyone know if this is possible in orca?
