I think your RMSD of 0.000539742 is quite a small value, which can be, at least theoretically, caused by the accumulation of errors. Can you simulate your protein for a longer time to show that RMSD is indeed significant? On Sat, Jul 28, 2012 at 1:01 AM, wrote: > Hi, > my problem is, that duri

Hi, my problem is, that during the md run the atoms are not frozen somehow. During the minimization run everything worked out fine. But when I did a md run the hydrogen atoms and the other atoms seems to be changes somehow. I calculated the RMSD value and this is why I know that they change. After
