[gmx-users] Position restraint some molecules of a moleculetype in a system

[Khuong Truong Gia]

Hi all,

I am using gromacs to run md simulation and I in my system I have 10
molecules of moleculetype A. I want to set position restraint for 3
molecules of moleculetype A and let 7 remained molecules relax. Can anyone
help me to archive this goal?

Thank you very much,
Khuong
