[gmx-users] re-weight Metadynamics trajectory from Plumed to make it canonical ensemble

2016-01-13 Thread Christian Bope Domilongo
Dear All, I have run my Metadynamics simulation perfectly using plumed. I have check in the tutorial and website to find if it is possible to reweigh my meta trajectory as a function of FES and obtain a average trajectory which is a canonical ensemble. Because the trajectory obtained from plumed

Hi all, I used g_polystat command in gromacs to compute persistence length and I define atom group in index.ndx file. The result is like Average end to end distance: 0.203 (nm) Average radius of gyration: 0.051 (nm) Average persistence length: *2.00 bonds* (? why not in nm?) Regards, -- Gr
