Hi Justin, That works really fine and thanks.
Now, how can I add additional SOL molecules only one side of the bilayer (either upper or lower)? Since my protein binds at the outer side (extracellular region) of the membrane I can only fill the upper (extracellular) region with SOL molecules instead of adding them also inside the membrane, to reduce the system size ? Can we do magic here with any commands to add SOL molecules only single side of the membrane?
