I'm also having trouble with g_helixorient and the data it is giving me.
My desired end goal is to track the average tilt of a helix compared to
the global Z-axis, but a change in the tilt of the helix over time to its
reference structure (frame 0) will suffice.
How exactly do I interpret the tilt angles from g_helixorient? If I specify
4 CA atoms in the center of my helix, it seems to give me a running average
of some sort with 0 angle angle 0. What is this angle in relation to?
