What is the exact meaning of the natn array? Judging by its short definition in openmx_common.h I expected it to be number of an atom listed in an input file. But inspecting the values of this array for the file Lead-Graphene.dat (an example supplied with openmx3.6) I found that, for example, natn[1][1] through natn[1][8] have the same value - 1. So, obviously, natn[i][j] is not exactly the number of an atom which is neighbour j of the atom i. What is it then?

Hi,
In natn[i][j], i and j are a global and local indexes, respectively, where j corresponds to neighboring atoms for atom i, and 'neighboring' is defined by overlap of basis functions on atoms i and j. Then, natn gives us the global index for atom indexed by j.
