[gmx-users] How to view and analysis the result trajectory of g_covar?
Hi dear friends, I just get trajectory files using "g_covar". But how can I view this .trr file? I tried VMD and gOpenmol, etc and do not work. Thanks.

[gmx-users] Ligand often slips out from the binding site in MD; is it natural?
I am doing MD of a ligand-protein complex derivated from docking, but I found that often the ligand slipped out slowly from the binding pocket. I then performed some MD simulations of several complex ligand-receptor complex obtained from PDB database, but no similar phenomena was watched. Is it natural for a ligand to slip from pocket frequently? Or does it indicate that my complex model derivated from docking is unreasonable? What should I do? Thanks to all.

[gmx-users] How to generate average C-alpha fluctuation during MD of every AA residue?
Hi my dear friends, I just learn to use gromacs this days and I found a lot of figures in research articles that illustrates the average C-alpha fluctuation during MD of every AA residue, which can show very clearly that which part of protein is stable and which is flexible. But I examined the tutor and online manual for every commands yet cannot find the method. Please give me a hand. Thanks a lot.

[gmx-users] Why my protein always falls out of the water box?
Hi dear friends, I performed a molecular dynamics of a ligand-receptor complex for 5ns; but I found that my complex always fall out from the water box quickly in the first 1ns. What may be the problem? Can I constrain some residues which are far away from the active site to aviod this problem? But I am worry about the extra constrain would interfere my MD result, for in the normal situation there should be no constrains.

[gmx-users] genbox fatal error with ligand-receptor complex: realloc for atoms_solvt->atomname : No such file or directory
Hi, I am working on a molecular dynamics of a receptor-ligand complex. I created the .gro files for receptor and ligand separatedly and merged them together, making sure the atom numbers are continuous. In the .top file of receptor I have put " #include "ligand.itp" " and append a line for ligand in [molecule section]. Then I executed "editconf" successfully. When I execute: genbox -cp receptor.gro -cs spc216.gro -o receptor_1.gro -p receptor.top Error occured: --- Reading solute configuration CERM PROTESE Containing 982 atoms in 100 residues Initialising van der waals distances...
