Dear pymol users,

I have the trajectory file (.xtc file) of a protein using GROMACS. gmx
helixorient tool of GROMACS calculates it for each C-alpha atom of helix as
a function of simulation time. Whereas, I would like to calculate only ONE
helical tilt angle relative to the z -axis of a alpha helix for each frame
of simulation.

Does anyone have a script to calculate the helix tilt angle relative to the
z -axis of a alpha helix?

Any helps will be appreciated.
