[AMBER] Calculation of forces using steered MD

Hi all,


I hope that the details of steered MD method employed in AMBER be explained
more for non-professional users through the manual. During a pulling
simulation, such as DNA pulling, a force-extension curve can be obtained
from the output file which is generated by setting jar=1 (i.e. k*(x-x0) vs.
x). I’m not sure that if this curve can be compared with a similar curve
which is obtained from an experimental simulation (assuming the time scale
in the two cases are nearly equal); or firstly the potential of mean force
must be calculated and then forces obtained as derivative of the PMF?

Any comments would be greatly appreciated.



Thanks in advance
