Hi Jian, You would need to use the IDs of the axes (not model numbers) in the angle command. 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/ContributedSoftware/structuremeas/structuremeas.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
