[gmx-users] PBC problems related to comm-grps in membrane simulation?

2018-03-22 Thread D. Meral
Hi, I'm having difficulty with a membrane receptor simulation. It seems like whenever the receptor crosses the boundary (I'm using PBC), the box gets distorted so that the z axis is compressed from 10.2nm to 8-8.2nm which is too large a change. I was initially using System for the comm-grps optio

Hello everyone! I am a new one of gromacs. When a simulation of protein in water is finished, should i first use the command of trjconv to remove pbc conditions(with nojump or mol), and then began analyze the new trajectory(rmsd, Rg and some other parameters)? Is the result believable without
