As I was going through excellent step by step introduction as to how to
use AMBER for DNA simulation in tutorial section of AMBER home page I came
accross the following situation
I looked at atA.topo atA.topo.belly files and when I diff them I get
< 38 2883 3
< 319 319 1 1 1 1 1 1 1 1 1 1
< 1 1 1 1 1 1 1 1 3 3 3 3
---
> 38 2882 3
> 638 1 1 1 1 1 1 1 1 1 1 1
> 1 1 1 1 1 1 1 3 3 3 3 3
13807c13807
< 3 3 3
---
> 3 3
In the explanation below it is said that I should decrement NSPM by 1 and
NSPSOL by 1. So 2883 is dcremented by 1 but 3 is not dcrement by 1. Is
that a typo or there is some more to it.

I need to resolve it before making a belly topology file for my
simulation.
