.SH DESCRIPTION
.sp
\fBgmx awh\fP 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 \fB\-more\fP the bias, target and coordinate distributions
are also printed.
With \fB\-more\fP 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 \fB\-fric\fP prints all components of the friction tensor
to an additional set of files.
