[gmx-users] LINEAR INTERACTION ENERGY

[Kulkarni R]

Thanks.


You have mentioned "proper energy groups" in mdp file


Could you please say more about it?


Thanks,

Kulkarni.R

Basically you do two MD runs one with ligand in water other with ligand in protein. You must set proper energygrps in mdp file so you get 2 edr files from runs and in the end you use "gmx lie" (http://manual.gromacs.org/programs/gmx-lie.html) to compute difference between those two edr files.You might check this paper too:
gmx lie - GROMACS<http://manual.gromacs.org/programs/gmx-lie.html>

 Hi gromacs users,

In order to calculate delta G (Gibbs free energy) for protein ligand binding, what are the steps to be followed in Linear interaction energy?


Are there any tutorials for the same?


Thanks,
