[gmx-users] -ve value of z in g_wham

[Nilesh Dhumal]

Hello,
I trying to run umbrella sampling simulation for system.

After running g_wham command I am geting some negative value of z along x
axis.

g_wham -it tpr-files.dat -if pullf-files.dat -o -hist -unit kcal

Can any one tell why I am geting -ve value or what is the significance of
this.
