2012-12-23 Thread James Starlight
by the way it's also interesting to me if there are any other possible ways to obtain representation of the free energy surfaces in the essential coordinates subspace ? Might the methods like Ubrella sampling ( with applied PMF in the pulling direction along selected eigenvector ) or flooding (alr

[gmx-users] free energy

2012-12-23 Thread mohammad agha
Dea GROMACS Users, I want to calculate the free energy for my system, for example (Gibbs and Helmholtz), but I didn't define the free_energy in the md.mdp and my simulation has been finished!!! May I ask you that say me is there a solution fro this problem? Best Regards Sara -- gmx-users mai

[gmx-users] exact average distances with g_mdmat

2012-12-23 Thread IsaureCB
Dear gmx-users, I would like to select, for each residue of a model, the residues that are within 3.6 A in average over a simulation. g_mdmat must create this information at some point while generating the contact diagrams, but I would like to extract the real values before they are discretized
