Thank you Justin for your reply

as per your suggestion i verified the contents in confout.gro but i was
unable to check file as when i am clicking on it to open it I am getting an
message that file is of unknown type.

I again repeated the tutorial and I am getting the same things.

Thank you again for your time.
