A month is a reasonable time investment for quality MD simulations.

Very doubtful, but I'm not going to speculate further. You have to be willing
to put in significant effort to answer complex questions, unless you're happy to
settle for potentially unreliable data.
request to u guide me to a link where I can find more about this
independent simulation and how to run many replicates & analyze them ??
There's nothing left to say. I've told you how to initiate independent
simulations. Analyzing them is up to you based on your plans for this project.
No one on this list is going to provide you broad-reaching how-to's for doing
anything you might come up with. The manual is extensive, and the website/wiki
has lots of tips and information.

I am going to start simulation with these parameters.
As I have already said, the combination of velocity generation with
a different random seed will give you (in theory) independent
trajectories. How many replicates you run is up to you. I
certainly hope that, after all I've said, you're still not intending
on simply running 3-ns simulations, regardless of how many
replicates you run. If you're looking at loop movements, you won't
answer your questions with such little data.

conducting

independent simulation and for that I searched some
threads but
was not able to get the proper description and method... if u
can guide me through an appropriate link .. it would be much
more helpful ..
Each simulation begins with the assignment of random velocities
(gen_vel = yes). Specify different values of gen_seed (or
leave it
set to -1) to get different velocities each time.
