Thanks Ross for quick reply. I am up with some solution to my problem. Just
an extention to my previous query. In my case the final MD
structure seems to be slightly moved(tilted) away from the original
minimized structure. First MD was for 1ns and then for 2ns. In both
situations the final structure is tilted from the original structure, which
is due to a large loop region. I want to analyse my data. Which one
is proper way
1. Analyse the data based on MD output as it or
2. Analyse the data after overlaping the final MD struture into PDB file
obtained from minimization. In this case I also calculated the
rmsd and it is 1.4.
thanks a lot your help and time.
