[gmx-users] protein-ligand interaction energy for oligomers

2009-07-25 Thread Shankar Prasad Kanaujia
Dear gmx-users, I am working on a hexameric protein. I have done simulation of protein-ligand complex (hexameric i.e. 6 protein monomers and 6 ligands). I want to compare the interaction energy of protein-ligand (energygroups= protein ligand sol) with the biochemical data (delta H). The protein-lig

[gmx-users] time of simulation

2009-07-25 Thread mahmoud
Hello Dear GMX Users,     I have installed Gromacs 4 on a QUAD computer by Fedora 11.   When I do not use the "mpirun -np 4 g_mdrun ... " command, just one CPU is used. When I use the "mpirun -np 4 g_mdrun ... " command, all of the 4 CPUs are used.   But the problem is that the time of simulation,

[gmx-users] How to know the electrostatic potential at a given coordinate?

2009-07-25 Thread accomp lin
Hi everyone   I wish to know the electrostatic potential for any given position in my system (3-D). g_potential seems only calculate the sum potential in a slice of a simulation box. So is there any way to obtain the entire potential map for a system by existing gromacs tools?   Thanks in advan
