Description
gmxawh extracts AWH data from an energy file. One or two files are written per AWH bias per time frame.
The bias index, if more than one, is appended to the file, as well as the time of the frame. By default
only the PMF is printed. With -more the bias, target and coordinate distributions are also printed, as
well as the metric sqrt(det(friction_tensor)) normalized such that the average is 1. Option -fric prints
all components of the friction tensor to an additional set of files.
