Thank you for your valuable response . It was my mistake. I was giving wrong
input for unit cell. Actually i think (6,0) zig-zag CNT should have 20 atoms in
it's unit cell.

You could delete the *DM file and restart.
However, your unit cell seems not ok?
I would say 6,0 has 24 atoms in the unit cell.
Cheers Marcel
