Hi
Thanks a lot for help. I could run the EM with ATP in its right place. But
position restrained dynamics gives warnings saying that some angles are rotated
beyond 30 deg. So when i directly went for MD run it is running fine. What
dis-advantages i have of not performing position restrained dynamics on my
ATP-receptor complex system ?
Regards,
Nikhil

pdb2gmx tries to cap termini of peptides automatically, but this isn't a
peptide. So look at pdb2gmx -h and choose the option that will allow you to
interactively choose that no terminal capping needs to take place.
