Hi GROMACS users,


I have done simulation of a membrane protien named aquaporin5 which transports water across the membrane. I have done simulation of 3 ns and want to pass water molecules during simulation. Is it possible to do in GROMACS? I want to know how to do?

3 ns is far too short of a timeframe to see this type of activity spontaneously. You may need tens or hundreds of ns. You can force water through the channel with the pull code, but I would suggest you refer to the literature to see what others have done; you are not the first to try to get water or small molecules to move through transport proteins.
