Hi Tsjerk,
Thanks for your response. I mean edge of decane-water interface. I have a protein solvated in water and I want to measure distance between the interface and protein over time.

Hi Abu,
What edge? There are no edges when using periodic boundary conditions. Is
there any particular reason why you would need such a measurement? If you
want the "distance to the wall", you will need to calculate the minimal
distance between periodic images (g_mindist -pi) and take half of that. You
could ofcourse take the maximal z-coordinate and subtract it from the third
number of the last line of the .gro file (which gives the z component of the
third box vector).
Cheers,
Tsjerk
