I realize a targeted MD simulation . On having analyzed the results, I find
with some "surprises" that I would like to help me to resolve:
1.-On having initiated the simulation, NAMD indicates that the RMSD of TMD
simulation is 14, and diminishing (as it must be in TMD). But when I
graphical the RMSD of the trayectory in VMD (RMSD trayectory tool), the
a) It goes in increase
b) it never reaches 14, only reaches 4
Why the RMSD so different?... At best cases, the graph in VMD should begin
in 4 and to reaches to 0, but it is on the contrary.
2.-NAMD indicates that on having finished the simulation (3ns), the RMSD is
virtually 0 (0.000103125), which means that it reach the final structure.
Nevertheless, on having observed the path, it does not appreciate that the
final structure is reached. Why is this? ? Is it a convergence problem of
TMD in NAMD? Is simulation very short time?
Any suggestion to me is useful.
Thanks in advance
