I tried to use a cutoff distance 999 assuming that is big enough to have
all non-bond pairs with no cutoff ( I guess thats what you also mean by no
cutoff). Still the same problem.

In the system I have 10-mer DNA (20 bases), Na+ and water (all together
11638 atoms). So I have defined 20 bases as 20 groups and I guess rest of
the system is treated as one more group. Thats why we see 21 groups. I
have verified this by explicitly definfing the 21 st groups with the atoms
belonging to Na+ and water.
