Dear Amber,
Thank you for your reply. i already create a new script with nmropt=1. i
also removed the group definition (as your advice-actually i want to
restraint but at mean time i just want to see wether the temperature can
cool down or not). the script that i creat, i put it at the bottom of the
email. as u mention about the output file, it seems that everything is
fine. i paste also the output file for you to look at it. thank you.
