Hi. I guess that you can try to make a quite long DNA and make the length of the box very close to the length of DNA and apply periodic boundary condition.
You could freeze the DNA chain and make it longer to save time.
That's my guess.

By using namddat I averaged van der Waals energies of my protein - protein complexes, and the sign of the average and the all the energies used in calculating averages were (+) positive.
When I was looking for it in the literature, I came across with numbers which are negatives(-).
Is there anything wrong, or this is depend on something else, I mean the sign of Van der Walls ?
ps. I did simulate a homodimer which has 200 aa. total. It was solvated and added counterions. I used NVT ensemble and CHARMM_27 parameters....
