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 On 05/29/2012 04:45 AM, Xinghua Qin wrote: > hi, > how do I calculate the rotation angle of a certain helix in structures > with different ATP analogues? > and how if it is a domain ? > Best wishes > Xinghua Qin > > -- > Xinghua Qin > State Key Laboratory of Plant Physiology and biochemistry > College of Biological Sciences > China Agricultural University > No.2, Yuan Ming Yuan West Road > Haidian District, Beijing, China 100193 > Tel: +86-10-62732672 > E-mail: xinghua...@126.com -- Thomas Holder MPI for Developmental Biology Spemannstr. 35 D-72076 Tübingen ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
