[gmx-users] Need some help with membrane simulation

2014-06-05 Thread Ali Khan
Hi all, I don't know if anyone has experienced this problem before, but I figure I ask. I have several times run a simulation on a 135A x 135A POPC membrane acquired fro the charmm-gui website. I wanted now to simulate one that was slightly larger (150A x 150A). I made the larger membrane on

I used to have this problem in pymol as well. When I upgraded pymol to version 1.7, the problem was fixed and the whole protein would be displayed. On Wed, May 28, 2014 at 10:19 PM, bharat gupta bharat.85.m...@gmail.comwrote: I checked the structure in VMD, it shows all the chains now but the

;-) concentration = quantity / volume. From the factor of ~1000, probably you're inputting box sizes in A instead of nm, or vice-versa, somewhere. Mark On Tue, May 13, 2014 at 8:43 PM, Ali Khan ak...@virginia.edu wrote: Hey, I generated a membrane in charmm-gui that I will be simulating
