6 gmx-awh - Extract data from an accelerated weight histogram (AWH) run

9 gmx awh [-f [<.edr>]] [-s [<.tpr>]] [-o [<.xvg>]] [-fric [<.xvg>]]
10 [-b <time>] [-e <time>] [-[no]w] [-xvg <enum>] [-skip <int>]
11 [-[no]more] [-[no]kt]
12
14 gmx awh extracts AWH data from an energy file. One or two files are
15 written per AWH bias per time frame. The bias index, if more than one,
16 is appended to the file, as well as the time of the frame. By default
17 only the PMF is printed. With -more the bias, target and coordinate
18 distributions are also printed. With -more the bias, target and coor‐
19 dinate distributions are also printed, as well as the metric
20 sqrt(det(friction_tensor)) normalized such that the average is 1.
21 Option -fric prints all components of the friction tensor to an addi‐
22 tional set of files.

30 -s [<.tpr>] (topol.tpr)
31 Portable xdr run input file

33 Options to specify output files:
34
35 -o [<.xvg>] (awh.xvg)
36 xvgr/xmgr file
37
38 -fric [<.xvg>] (friction.xvg) (Optional)
39 xvgr/xmgr file

43 -b <time> (0)
44 Time of first frame to read from trajectory (default unit ps)
45
46 -e <time> (0)
47 Time of last frame to read from trajectory (default unit ps)
