Infinity and NAN in the CDFT.txt

Dear All,
I'm trying to calculate all CDFT indices for my system (which is a complex metal cluster of 4 Mn and a calcium ion connected through bridging oxygens). However, I'm getting a lot of NAN and infinity values. For example:
Condensed local softnesses (Hartree*e) and relative electrophilicity/nucleophilicity (dimensionless)
     Atom         s-          s+          s0        s+/s-       s-/s+
     1(C )    Infinity    Infinity    Infinity         NaN         NaN
and
E(N):        0.000000 Hartree
E(N+1):      0.000000 Hartree
E(N-1):      0.000000 Hartree
E_HOMO(N):     -0.171208 Hartree,   -4.6588 eV
E_HOMO(N+1):   -0.122035 Hartree,   -3.3207 eV
E_HOMO(N-1):   -0.176132 Hartree,   -4.7928 eV
Vertical IP:    0.000000 Hartree,    0.0000 eV
Vertical EA:    0.000000 Hartree,    0.0000 eV
Mulliken electronegativity:     0.000000 Hartree,    0.0000 eV
Chemical potential:             0.000000 Hartree,    0.0000 eV
Hardness (=fundamental gap):    0.000000 Hartree,    0.0000 eV
Softness:    Infinity Hartree^-1,  Infinity eV^-1
Electrophilicity index:         NaN Hartree,       NaN eV
Nucleophilicity index:     0.163990 Hartree,    4.4624 eV

Why is that? what did I do wrong?
Thank you

Re: Infinity and NAN in the CDFT.txt

Which files did you use for CDFT analysis? How did you generate them? I need more detailed information.

Re: Infinity and NAN in the CDFT.txt

Thanks.
I generated the N.wfn, N+1.wfn and N-1.wfn files using Gaussian09. I used the B97D functional and 6-31g(d) basis sets for all atoms except Mn and Ca, I used LANDL, which is similar but with effective core potential.

Re: Infinity and NAN in the CDFT.txt

Please send the three .wfn files as well as the corresponding input files of quantum chemistry program to my E-mail, I'll check.
