Hi,
when I am doing NPA-NBO calculation for my structure, I got following error:
***********************************************

NATURAL ATOMIC ORBITAL (NAO) Analysis

***********************************************

## Threshold for occupied or Rydberg orbital in NAO calc.: 0.850000 elec.
Maximum number of L = 3
Maximum number of M = 2
Size of full matrix = 272
