[gmx-users] Minimum distance between periodic images
Dear all users I have simulated a protein with two chains (153 residues each) for 50ns(restarting crashed run 3 times) using a cubic box with each side as 11nm. After finding the closest distance between the periodic images, I found that the closest distance becomes lesser than 1 after 23ns for few ns and then again shoots up (and fluctuates around the previous value) and then again becomes lesser than 1 around 49ns.The command which I used: g_mindist -f md-run-1-noPBC.xtc -s md-run-1.tpr -n index.ndx -od mindist.xvg -pi Similar trend is seen when I plotted rmsd curve and distance between the two chains or any other analysis curve (ie at those specific time intervals in between, the value shoots up) My question is : Will it be reasonable enough to carry out my analysis for first 22ns and discard the rest? Is this the problem due to smaller box size or some other parameter as the previous studies (through literature survey) have used even much lesser box length (although their simulations were also of short duration than 50ns). I have posted the output of minimum distance between periodic images at : https://plus.google.com/photos/109332801667278171972/albums/5937501788329595121?authkey=CJHD-9XO7dH4jgE and rmsd wrt c alpha at : https://plus.google.com/photos/109332801667278171972/albums/5937501062407227393?authkey=CKOE9sP5pMO2NA Please help me figure out the problem.

[gmx-users] Regarding membrane(DMPC) simulations with fullerene
Dear Sir, I am doing fullerene interaction with DMPC , i downloaded the gro file from the website mentioned in the tutorial. I was keep the fullerene on the top of DMPC. But in the gro file already water is present. If i removed that water molecules and adding new water molecules by using genbox command and afetr the running energy minimization the lipid structure was collapsed. it is not like initial structure and some gaps were found in the middle of membrane. By keeping the water molecules as such from the gro file and i keep the fullerene above the membrane then the presented water molecules were randomly distributed inside the membrane, and structure of water was distrubed. If i added water using genbox to the membrane( with water from gro file), there is a seperation found between two water layers. Energy minimization was not running in all above cases. How can i run this simulation please suggest me Is there any tutorial like this simulation.

[gmx-users] a new GROMACS simulation tool
Hi Everyone, I'm writing to let you guys know that we have developed a web-based tool MD simulation tool for GROMACS. It is a software package primarily developed for biological MD and offers a huge amount of possible options and settings for tailoring the simulations. Seamlessly integrated with newly developed GUI interfaces, the tool provides comprehensive setup, simulation, analysis and job submission tools. Most importantly, unlike other GROMACS GUI applications, user can actually run really simulations using the dedicated HPC resources. That been said, there's no proposal and installation required. This tool could be a great fit for both teaching and research projects. Users inexperienced in MD can work along prepared workflows, while experts may enjoy a significant relief from the tedium of typing and scripting. As for now, we'd like to invite people to participate in user testing on this newly developed tool. Let me know if you'd like to try it out. We will set up an account for you.

Dear all, I have some doubt for the output force. What contributions do the output forces in .trr file include? Certainly, the pair forces and bonded interactions are included. However, if the external field (such as electric field) is applied, is the external force included? In addition, if the constraint (such as LINCS or SHAKE constraints) is used, is it also included in the output force? If so, how is the constraint contribution calculated?

[gmx-users] Conflicting atom names when using g_density
Hi Everyone, I am having an awkward situation. I want to use g_density to get the density profile of a lipid bilayer. At first glance, it looks like a trivial task. But for my case, it's not because I have conflicting atom names from two different molecules. I am using GROMOS 53a6. In DPPC topology, I have C1 C2 C3 N4...O7... In another lipid topology, say lipid B, I have C1 C2 C3 N4... C7... The C1 in DPPC and C1 in lipid B could have different atomic mass as GROMOS is united atom representation. C1 of DPPC could be a CH2, C2 of lipid B could be a CH3. Then I don't know how to specify the entry in the .dat file: C1 = ? Is it possible to calculate the density profile of the whole bilayer by just invoking g_density once? Or in my awkward situation, I have to calculate the density profile of each molecule type, then add them together? Then I will be concerned with the numerical errors involved. Thanks.

CMake has not yet updated their compatibility matrix for 2.8.12 ( http://www.cmake.org/Wiki/CMake_Version_Compatibility_Matrix/Commands) and as you can see there, things that used to work occasionally stop working. If you can try a different version of CMake we can rule out bugs in CMake 2.8.12. Mark (Redirected from gmx-developers) The only way I can reproduce those symptoms is if I delete (or otherwise make unreadable) various parts of src/gmxlib.

[gmx-users] Energy minimizations taking really, really long?
I have some simulations of inserting a probe molecule into a bilayer. Some molecules work fine. However, a certain class of molecules is taking an absurdly long time to run the exact same simulation, even though I energy minimized the molecules individually beforehand and there are no overlaps. What might be going wrong?

[gmx-users] Re: Energy minimizations taking really, really long?
It depending the time steps that u used or the molecule that u had is big..Thats why ur EM take a long time..Is better take a long time rather than quick but had a lot of errors..

[gmx-users] Continuing runs from 4.5.4 in 4.6.3
Hi, We recently had a software upgrade in our cluster from gromacs 4.5.4. to gromacs 4.6.3.. I need to continue an earlier simulation that had been run in 4.5.4. using the .cpt, .tpr and .mdp. Are there any issues with continuing these runs in 4.6.3.? Can I concatenate these trajectories for later analysis? I notice that I cannot use a 4.6.3 .cpt and .tpr in 4.5.4. Any input will be appreciated. Thanks. -- Rajat Desikan (Ph.D Scholar) Prof. K.
