Dear users I performed 20 ns simulation for protein complex. After 10 ns only my system obtained equilibration state . I would like to analyze last 10 ns from the trajectory file.I got problem to generate last 10 ns xtc file from the 20 ns trr file.

2012-09-24 Thread naga sundar
Dear gromacs users We performed MD simulation analysis for native and mutant models of protein-protein complexes. From 20 ns simulation trajectory, we generated RMSD graph for one native and three mutant complexes. For native complex in the entire simulation period, we observed a

Even after repeating the 20 ns MD simulation two times i got the same results. On Mon, Sep 24, 2012 at 3:41 AM, Justin Lemkul jalem...@vt.edu wrote: On 9/24/12 6:24 AM, naga

Dear simone I think so u r using the same pr.mdp and md.mdp files what u created initially. So open both the mdp files replace DRG with UNK and the try sure it will work out. On Tue, Sep 18, 2012 at 9:44 AM, Justin Lemkul jalem...@vt.edu wrote: On 9/18/12 12:42 PM, SIMONE

Dear gromacs users I run 20 ns MD simulation for protein mutant complexes. In RMSD analysis at ~9 ns sudden increase in the deviation was observed from 0.2 nm to 1.7 nm and immediate fall was observed. I rerun the 20 ns simulation for the same molecule with same procedure. While analyzing the
