[gmx-users] DNA strands disconneting from each other along MD simulations

Hi GROMACS users !
I am using amber force field to perform 10 ns MD simulations of a
DNA dodecamer docked with small molecules in order to check if these
molecules stay between the strands interacting with the nucleotides,
but, after the simulations, I've observed that sometimes the DNA strands
disconnect totally from each other and some ns later get together again.
I initially thought that it would be a bug of the VMD software (that I
used to visualize de MD results) but when I analysed the temporal RMSD
plots, I've saw big peaks at that times the DNA strands separated from
each other. Does someone knows why the DNA strands are disconneting from
each other and how to fix it ?
With the best regards,
