Thank you. But it just adjusts the cut-off between atoms not the number of hydrogen bonds in a given distance above the surface (or in the box). would you please help me? Best On Sun, Jan 6, 2019 at 9:12 PM paul buscemi wrote: > Use VMD/extensions/hydrogen bonds > > > On Jan 6, 2019, at 11:01 A

Hi Negar, Correct, the -dist option doesn’t do what you want it to. I cannot come up with a recipe for how to do this, but I suspect multiple rounds of gmx select and gmx hbond might do the trick. Kind regards, Erik __ Erik Marklund, PhD, Marie Skłodo

Hi, A quick glance at the code suggests Justin is right. You should be able to inspect the output of gmx hbond and see that in fact -e means that many fewer trajectory frames are being read. Mark On Tue, May 2, 2017 at 2:56 AM Justin Lemkul wrote: > > > On 5/1/17 10:15 AM, Marcelo Depólo wrote
