[gmx-users] Questions about the MFFA boundery implementation of Gromacs?

[song.yongshun]

 Dear all:
I was using the MFFA version of Gromacs which is provided by m.j.louhivuori at http://md.chem.rug.nl/~mara/mffa.html.
I have some quesition about this version:

i.I saw the implementation of MFFA always with the flip-flop of lipid.Can I apply the flip-flop with this MFFA version of Gromacs ?
ii.I also saw the description of implementation of MFFA along only one direction.Is this available in this MFFA version of Gromacs?


Anyone who is familar with it help me.
