I am currently using DistanceZ for my colvars definition and everything
goes fine except it does not gives me the value I expect.
I thought DistanceZ was measuring the subtracted vector between the centre
of mass of atoms in the main group and that in the ref group and then
projected it onto the z-axis, in other words only the z component is of the
interest. In my system,
com of main locates at z=40
com of ref locates at z=-55
However the first step (step 0) of colvars.traj gives me -65 for DistanceZ.
As I'm doing the umbrella sampling, it's fine if I change my windows list
according to z=-65 but I'm just curious what DistanceZ was actually
Thanks in advance,
