[gmx-users] Free energy landscape

2019-03-15 Thread RAHUL SURESH
Hi users I find few methods of plotting free energy landscape. Of them one is plotting rg vs rmsd and another one is using Principe components. What is the difference in these two methods? Is the plot obtained by both the method are one and the same? Thank you -- Gromacs Users mailing list * Pl

Sounds like a problem for string methods. However, it's hard to judge without actually looking at what you have. Cheers. On Sun, May 13, 2018 at 3:47 PM Rezgar Pakravan wrote: > ​HI there > > I got free energy landscape using Mathematica software to get coordinates > with the least free energy.

​HI there I got free energy landscape using Mathematica software to get coordinates with the least free energy. 3d image of the landscape shows a gap though!? would that be reliable to get coordinates from any point on the lowest energy coordinate ? any recommendation would be appreciated Pakr

Hi, The trjconv -drop* functionality is useful here. IIRC it only does a 1D form, but you can do two stages of that. Mark On Fri, 16 Dec 2016 02:36 Romero, Raquel wrote: > Thanks a lot, I know how to do it now, so each value given in the > 2dproj.xvg corresponds to a time step of the simulatio

Thanks a lot, I know how to do it now, so each value given in the 2dproj.xvg corresponds to a time step of the simulation, right? so if I delimit the area in the FEL of which I want to know the coordinates i can extract all the frames that correspond to those eigenvalues by searching in the fil
