The task should be completed very soon.

is Multiwfn able to calculate or extract "natural population analysis" from the .chk or fchk file?
i restarted an opt +Freq job with the keywords opt=restart, pop=nboread... but the output file do not contain any NBO section as it should ( i need the natural population analysis) ! i want to avoid re run the optimization process for time saving purposes
