[gmx-users] Fwd: »Computational Electrophysiology«

2019-04-02 Thread Harutyun Sahakyan
Dear Gromacs users, I am trying to simulate membrane potential using computational electrophysiology protocol. I modeled protein-membrane system with charmm-gui, equilibrate it and run MD simulation. After some steps, I get this error.

[gmx-users] Saving filtered trajectory using gmx anaeig

2019-04-02 Thread James Starlight
Dear Gromacs users! Normally to save a filtered trajectory (as NMR-like ensemble) along selected PCs i use gmx anaeig -v eigenvect.trr -s reference -f $dcd -first 1 -last 2 -filt snapshots_alongPC1_PC2pdb Would it be possible to save a fewer number of snapshots in the -filt trajectory but with

@Peter: Please don't take it the wrong way, it was just my lame attempt at a tongue in cheek reply to your comment. Now, to actually contribute with something of relevance to the topic at hand, I agree with what most users/developers have mentioned before, i.e. a ligand binding study using mixed

Hi Mac Kevin E. Braza, Would it be possible to use a GPU?  If can manage with single precision and need less than 8Gb of memory, a gaming GPU might give some performance improvement. Regards, Benson On 4/2/19 11:46 AM, Peter Kroon wrote: @Joao: I didn't mean to imply in any way that

@Joao: I didn't mean to imply in any way that everyone has (or should have) a couple hundred nodes at their beck and call. Although it would be nice. I underestimated the size of the GPCR complex, as well as how slow atomistic simulations are :) Now that I've tried to pull my foot out of my mouth

[gmx-users] query regarding type of MD for protein protein interaction

2019-04-02 Thread p t
Hello All, this is not a working problem in gromacs, but rather a starting problem i am facing. I have to study GPCR oligomerization and will do the simulation in a lipid bilayer environment, and later also find kinetic rates through simulation. I read a lot of papers, some suggest Replica
