[gmx-users] g_dist as an alternative for g_saltbr

2014-10-15 Thread Diogo Martins de
Fellow users,I have read several emails exchanged in this discussion list where g_dist is presented as a better choice for observing salt bridges in the trajectory. And I'm totally inclined to agree with that, but that would be the case where you already know which are the SBs present in the

open your .mdp in an editor and under energygrps, add " ProteinSurface" after the last term.Run grompp using this .mdp and create a new .tpr. Then use the command line Justin mentioned

That can certainly work for me! Especially because I know my groups functional groups. I guess if one was still in doubt what to focus on, then my idea could still be useful (with a bit more of work). Now, just so I get things right: 1. I got to make ONE group in my .ndx that contains all my

[gmx-users] Decomposing the long range term of interaction energy

I've been reading many tentatives of breaking down the long range term of interaction, but have not found a feedback if any actually worked. Is there a working method of achieving this? Att. Diogo -- Gromacs Users mailing list * Please search the archive at

[gmx-users] Comparing two Ptn-Ptn docking models

2015-03-12 Thread Diogo Martins de
Hi all, I have two proteins which I've docked and obtained two models, dock1 and dock2. Both corroborate, to some point, with literature experiments. I ran both models in a 76ns simulation, using 43a1 force field and PME. I have managed to map all salt bridges and their distances through the

[gmx-users] enemat output

2015-03-10 Thread Diogo Martins de
Hi guys, Can any one show a picture of how a normal enemat output should look like? Since the bug in enemat was only fixed in version 4.6.5, I have a very basic question: Can I install a newer version of gromac (say 5) and use its enemat to treat .edr files from older versions (i.e. 4.5.3 and

[gmx-users] short-range eletrostatic energy of every aminoacid

2015-05-25 Thread Diogo Martins de
Hello guys, I'd like to do make an energy matrix of every aminoacid of a simulation of two interacting proteins. I know enemat can assess the matrix, but for this I have to define energygroups in .mdp files. What would be the easiest way to achieve this? Thanks in advance. Regards, Diogo --

Hi Nikhil, You can get CUDA toolkit 7.5 using apt-get install nvidia-cuda-dev nvidia-cuda-toolkit. Also, if you open the link I've sent, you`ll see the step on how to install directly from provider. NAMD ran with CUDA this way. So it is supported. Installing directly with apt-get gives the same
