Re: [PyMOL] calculate the rotation angle of a certain helix in structures with different ATP analogues

[Thomas H. <sp...@us...>]

Hi Xinghua,

you can install the "psico" module which provides commands for both of 
your tasks:

  * angle_between_helices
  * angle_between_domains

PyMOLWiki page:
http://pymolwiki.org/index.php/Psico

Direct download link:
https://github.com/speleo3/pymol-psico/zipball/master

After having installed psico, read the help pages for both commands:

PyMOL>help angle_between_helices
PyMOL>help angle_between_domains

An older version of the "angle_between_helices" command is also 
available as a separate script:
http://pymolwiki.org/index.php/AngleBetweenHelices

Cheers,
   Thomas
