[gmx-users] protein dna pulling

[abhisek Mondal]

Hi,
I have been trying to pull a double stranded DNA from protein's binding
surface. But I am facing an issue. After defining the pull vector when I
apply the pull force the DNA's one stand got pulled completely while other
strand partially remain attached (

).
Shouldn't the both strands be moving together (as the COM was determined
using residues from both strand of DNA) ?
Some suggestions in this regard would be highly appreciated.
Thank you.
