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.


You can use whatever geometry makes sense. There is no reason to believe that any particular geometry is inherently "right" or "wrong" for any given purpose, and generally speaking, if utilized properly, you can usually use any of the geometry options to achieve equivalent effects.
