I'm trying to do  [8 Orbital composition analysis -->  7 Orbital composition analysis by natural atomic orbital (NAO) method] via ORCA5.0+NBO7 programs.
My input files are like below

! PBE tightscf nbo
%nbo
NBOKEYLIST = "$NBO NAOMO AONAO DMNAO $END"
end
%pal nprocs 4 end
%maxcore 6000
* xyz 0 1
c 0 0 0
o 0 0 1.128
*

and with this input,
I got this error message --> [ Error: Cannot found natural population analysis information in the input file!]

Any ideas for solving this issue?
* I loaded .gbw file after setting orca_2mkl path to the setting.ini file.

Thank you for the help.
