Dear all, thank you very much for your suggestions. At the end I have used the script that Thomas provided and I got the angle between the two helices. Best wishes, Almudena. 2015-03-04 20:13 GMT+01:00 Thomas Holder : > Hi Almudena, > > you can do it with PyMOL, using PSICO's angle_between_he

Hi Almudena, you can do it with PyMOL, using PSICO's angle_between_helices with the "cafit" method. Example: run https://raw.githubusercontent.com/speleo3/pymol-psico/master/psico/orientation.py fetch 3pt6, async=0 as cartoon angle_between_helices chain D+J, chain I+C, cafit Hope that helps.

Hi Almudena, You can extract the vector for the helical aixs by 3DNA, and then calculate the angle between the vectors. I hope this help! Best, Chen On Wed, Mar 4, 2015 at 1:12 PM, Pavel Afonine wrote: > > I would like to ask if any of you know how to measure the angle between >> two nucleic

Hi everyone, I would like to ask if any of you know how to measure the angle between two nucleic acid helices? I am trying with pymol, but have not found a solution to it yet. Any ideas? Thanks a lot. Best, Almudena.
