Re: [gmx-users] No convergence with g_nmeig

2015-11-20 Thread KARAKAS Esra
Dear gromacs users, I still have the same problem with the vector convergence. There is a link with the size of my protein (18 081 atoms) ? I tried with a small molecule composed with 826 atoms and it seems to work. Any idea, please. Best Esra Hi,

[gmx-users] H-REMD in umbrella sampling

2015-11-20 Thread adam
Hi, Is Hamiltonian REMD possible with umbrella sampling in pure gromacs 5.1 without plumed patch ? It should be according to gromacs 5 paper and manual but no details are provided of how to use it. If yes, does anyone successfully applied it and could share sample mdp options used to exchange

Dear Gromacs users, I wonder whether it is possible to calculate the inertia tensor for the molecules? Thank you in advance for the answer Sten Sarman -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! *

[gmx-users] Dumping centers of mass of molecules during MD simulation

2015-11-20 Thread S.M. Golam Mortuza
Dear Gromacs User, Instead of dumping all atoms of a specific type of molecules, I would like to dump centers of mass (COM) of the molecules during MD simulations in Gromacs to reduce trajectory storage. I know g_traj can be used to dump COM of molecules from trajectory files. But, in that

Re: [gmx-users] Center of mass removal for a trajectory which is already created

2015-11-20 Thread Faezeh Pousaneh
To whom may have similar problem, that is how I solved it: First of all, Gromacs by default uses center of mass removal (at least in versions I use), but that is for 'whole system'. In my case I have a two-component system and I am interested in collecting density for one of the components. So,
