Dear All AMBER users,
I performed MD simulation using pmem.cuda (AMBER 2011 package) on GPU
workstation and found that trajectory does not stabilized even after 10ns.
the details are as follows :

1) MD simulation using ff99bsc0 forcefield: even after ~12ns of MD run
the trajectory is not stabilized (TRAJECTORY SHOWN BELOW ) ???

2) MD simulation using FF99SB force field: in this case also trajectory not
stabilized (RMSD plot below) ??

I am also attaching images (above) and input files for MD runs
Thanking you
Waiting for your reply..
