I have not constructed the system but I have downloaded it from ATB
website. To maintain the number of TFE and water molecules(1:1 v/v) in the
system (I don't want to add extra water molecules) I tried many options in
genbox but still it adds 678 water molecules. Can you provide me some hint?
Is their need to remove periodicity of this pre-equilibrated system as in
case of lipids?
