Hi Elaine, Thank you so much for your reply. I made the axes by myself through “measure rotation”. It generated axes models. If “angle” command only show the smaller angle, why I got angle of minus and even more then 90 degree?

The IDs are shown in the Axes/Planes/Centroids list of objects. You could have specified the IDs when you made the axes, or they would be generated automatically. < <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/angle.html> http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/angle.html> < <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/structuremeas/str ucturemeas.html#axes> http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/structuremeas/stru cturemeas.html#axes> So the command would be something like: angle a1 a2 It gives the smaller angle, treating both axes as infinite lines.

Hi All,
I made two axes for two molecule, and want to measure the angle between them. Let's say, #1 and #2 are the two axes. I used command line of "angle #1 #2" to do that.
Question:
What is the default angle measurement? The #1 rotate clockwise or anti-clockwise to reach #2?
Thanks,
Jian
