[gmx-users] Regarding umbrella samplling

[Sathish Kumar]

Hai gromacs users,

                             Can we use the direction-periodic mdp option
while running the samplling of windows instead of distance. The distance
option was giving error that

Distance of pull group 1 (15.017257 nm) is larger than 0.49 times the box
size (15.033495) .

So, for all windows can i use the option direction-periodic instead of
distance.

Thanks
Sathish
