Hi, I have a script that extracts the info from a minimization or md
run, from the .out and .mden files (amber 6 and amber 7, and namd
2.5b1), and using gnuplot automatically gives the plot. You can find a

It does not plot the ratio you are asking for, but can save a file with
all the data in column file, which you can import to any graphics program.
