Re: [gmx-users] Distance restraints on two TYR OH groups so that they are together
I altered distance restraints according to your comment into: [ distance_restraints ] 195 281 1 1 1 0.4 0.44 0.48 1000Still get same issue that 195 and 281 even move away from each other. Here link to all files again, hopefully it will not be distorted. http://www.mediafire.com/file/ruaxx6nbj2qpvm6/MD_4AK0_test_pub.tar.bz2 How can I drag 195 and 281closer with distance restraints? (not necessary as close as 0.2 nm) On Wednesday, March 15, 2017 2:54 PM, Justin Lemkulwrote: On 3/15/17 6:28 AM, Vytautas Rakeviius wrote: > Hello, I try to add distance restraints on two TYR OH groups so that they are > together in the end like this: > > [ distance_restraints ] > 195 281 1 1 1 0.2 0.22 0.24 1000 > But it does not work at least over time frame I tested, they even go further > away from each other. > > Here I share my all files:MD_4AK0_test_pub.tar.bz2 That's not a valid link. If you're trying to keep 2 oxygen atoms at a distance of 0.2 nm, that's well within the (likely) repulsive wall of the LJ potential, as well as being repulsive from the perspective of the electrostatics. You'll either need a massive biasing force to keep them close, or develop a different way to keep them at such a distance. Why are you imposing this bias, and at such a short distance? -Justin > System is small and easy to run (gmx grompp -f md.mdp -c npt.gro -t npt.cpt > -p topol.top -o md_0_1.tpr && gmx mdrun -deffnm md_0_1)What I am doing in > wrong way? > > | > | > | > | | | > > | > > | > | > | | > MD_4AK0_test_pub.tar.bz2 > MediaFire is a simple to use free service that lets you put all your photos, >documents, music, and video in a si... | | > > | > > | > > > -- == Justin A.

[gmx-users] Distance restraints on two TYR OH groups so that they are together
Hello, I try to add distance restraints on two TYR OH groups so that they are together in the end like this: [ distance_restraints ] 195 281 1 1 1 0.2 0.22 0.24 1000 But it does not work at least over time frame I tested, they even go further away from each other.
