Re: [gmx-users] a residue move in extremely large scale in MD

2012-08-07 Thread Acoot Brett
Dear Catch ya,   I have watched the trajectory of the simulation. Besdies, I got the PDb file for the whole 10 ns MD every 500 ps. Then I compared all the PDB files generated, and it confirms that 1 specific residues moves in an extremely large space.   Can you give me an explaination on it?   C

What information has "told you" that you have large scale movement? Where did that information come from, how was it generated? Have you watch the trajectory of this simulation to see how the residue actually moves? Catch ya, Dr. Dallas Warren Drug Discovery Biology Monash Institute of Pharma

Those tutorials show most important things (e.g. how to build topology for given system) in CG Martini ff using Gromacs. You do not have to merge anything. Commands are the same as for atomistic simulations http://bevanlab.biochem.vt.edu/Pages/Personal/justin/gmx-tutorials/index.html Jan _
