[gmx-users] orientation of a cubic system

[GIANMARCO BARTALINI]

Hello, I have a gro file that contains a cubic system
(water+membrane+protein). Is there a way to align the box with the three
principal axes x y z? I see that with editconf -princ I can align it to x,
but y and z are pointing towards the corner of the box instead of being
aligned with the respective dimensions. I also know that I can rotate the
box setting an angle, but I would really need to find a way to do it
automatically, since I have to repeat the procedure on many different
systems. Any idea? Thank you in advance,
Gianmarco
