[PyMOL] measuring helix angle

[Hena D. <hdu...@gm...>]

Hi,

Can anyone guide me how to use the pymol script to calculate the angle
between two helices?
Where and how to edit the script? I have 2 helices in a pdb file as follows:

protein.pdb
hel1 is chain A: 6-20
hel2 is chain A: 26-39

Thanking you in advance...
Hena
