Hi Yeping, depends on what you exactly want to measure. I recommend to try the "angle_between_domains" command from the "psico" plugin.
Example: 1) Download and unzip https://github.com/speleo3/pymol-psico/archive/master.zip 2) In PyMOL: run /path/to/psico/fullinit.py fetch 1a00, async=0 angle_between_domains chain A, chain B For other use cases, see: https://sourceforge.net/p/pymol/mailman/message/30041352/ https://sourceforge.net/p/pymol/mailman/message/33003764/ http://pymolwiki.org/index.php/Elbow_angle Hope that helps.
