[gmx-users] MM-GB/SA analysis in Gromacs

[Anna Marabotti]

Dear gmx-users,

I ran several MD simulations using Gromacs 4.5.4 version, and now I'd 
need to calculate binding free energies using the MM-GBSA method. I 
searched through the manual and through the gmx-users archive, but I 
didn't find a way to do it. I found an old post in which it appeared 
that in the version 4.5 this possibility would have been available 
(http://lists.gromacs.org/pipermail/gmx-users/2010-July/052302.html), 
but it seems to me that this kind of analysis has not been implemented yet.
In another more recent post, I see that somebody has used mdrun -rerun 
in order to perform calculations, but I don't understand the correct 
procedure to use (apart from the suggestion of using .trr instead of 
.xtc files in order to avoid errors).

Does anyone have suggestions in order to do this analysis with Gromacs 
trajectories, before I make these calculations with another program?

Many thanks in advance and best regards
Anna
