Hi all users,
when I am using the gromacs to simulate the course grain model for DNA, it
seems that the software doesn't recognize my force field file. I have included
all the bond and non-bond parameters in the bon.itp and nb.itp file.
During my simulation , I found that the base pair for C-G which first are in
the balance distance always repel from each other so I try to increase the
value of epsilon to increase the dispersion between this pair but it still did
not work and the pair still repelled from each other after the simulation .
Then I tried like this " ; Gb2 Cb2 1 0.000194e10 0.00217e4 " in
my nb.itp file, I found that the simulation can still be carried on and the simulation
result is the same for this base pair.
Well, that line is commented out (;), so naturally it would have no effect.

So ,I got confused about this phenomenon . Can anyone of you give me some
suggestions?
Thank you in advance.
Yang
