[gmx-users] Regarding membrane construction

[陈功]

Dear Venkat,
I guess there are some other methods to generate  new lipid bilayer construct by using genbox -cp your_membrane_protein -ci lipid_monomer -nmol xxxcalculate by yourself -try 1000 -cs solovents.gro -p top.top -o new_conf.gro or using editconf & cat ...Another way, you can try the script packmol. Be more patient.  haha, I m also a new gmx user.
Good  luck,
chen gong

Subject: [gmx-users] Regarding membrane construction
Dear all,
I am studying a membrane protein of length 288 residues. I want to simulate
in a DPPC bilayer. I have downloaded dppc equilibrated bilayer from Peter
Tieleman's website as directed by Justin in his membrane-protein tutorial.
But I found 128 lipid membrane is not enough for my protein. From the
literature, I found I need  81 lipids in each leaflet. How can I construct
a 162 lipid equilibrated bilayer? I tried CHARMM-GUI to build it. But the
equilibration is giving RATTLE error. Please help me in this regard.
 
Thank you
 
Venkat
