[gmx-users] About pull force in COM pulling

[Lee Soin]

Hello!
I'm using COM pulling in GROMACS. Something I'm not clear about:
(1) Is the pull force in the output file pullf.xvg just the spring force in
umbrella pulling and the constraint force in constraint pulling?
(2) In .mdp file, "pull_geometry" is specified as "distance". Then, what
is the positive direction for the pull force?
Thanks!
