Re: [gmx-users] editconf -translate help

The slab is centered has the same height and width (y and z coordinates) of the box, however it is one third of the length (the x coordinate). Graphically, at the moment, it looks like this: _ | xxx | | xxx | |___xxx___| Where 'xx' is my slab (that is how the view comes up when I open the file in rasmol). The dimensions of the box (as listed in the .gro file) are 13.90030 4.02160 5.36640 As I previously said, I want the slab to be on the right side of the box, not the center, however I have tried several different things and it does not seem to want to work for me (however, I am unsure if I am using the proper values for -translate). What X Y Z coordinates should I use for this to translate it? the difference between new and old com. most likely 5 0 0 will do the trick. Thanks!

[gmx-users] superimpose pdbs
Hi! It may be a bit GMX off-topic: I am looking for a command line superimpose application that would be able to get all individual pdb files in folder and generated new pdb versions of them 3D superimposed. Something like what SuperPose ( http://wishart.biology.ualberta.ca/SuperPose/help.html) does, but then locally in my computer. Many thanks in advance.

[gmx-users] Regarding minimization of POPE:POPG lipid bilayer
I built a POPE:POPG bilayer in 3:1 ratio. Simplify. Start with pure POPE and pure POPG first. When I am minimizing the bilayer, bonds in head groups are breaking in POPE and POPG lipid molecules. Your topologies are incorrect. Start with a simple test system: a single POPE in vaccuum. while creating *.tpr file using the above file for minimization, I am getting fallowing message. calling /lib/cpp... In file included from pg-pe.top:5: dpopg.itp:10:8: warning: multi-line string literals are deprecated Why not take a look at line 10 (or line 8) in dpopg.itp? You are still a long way from simulating a protein in the bilayer. May I recommend that you try a little harder to solve your problems before posting (e.g. by reading the warning messages carefully and seeing what they mean for yourself, or by trying to find a simpler test system to narrow down the problem). In this way you will avoid decreasing your likelihood of receiving answers to the harder problems you may encounter. Good luck. ___ gmx-users mailing listgmx-users@gromacs.org http://www.gromacs.org/mailman/listinfo/gmx-users Please search the archive at http://www.gromacs.org/search before posting!
