Re: [PyMOL] rotate about an abitrary axis

[Andreas H. <ah...@bi...>]

Hi Minh,

you define a rotation axis by the rotation axis x, y or z (first 
argument in cmd.rotate) and a point in 3d (origin argument in cmd.rotate).
Instead of rotations around axes that are not parallel to the x, y or z 
axis you can do composite rotations.

Btw, for the case of GroEL (PDB 2c7e), the structure is oriented along 
the Z axis, so you can flap the flexible regions with a single rotation 
around the axis that goes through the regions center of mass and is 
parallel to the z-axis.
See the attached file.

repeat the last rotate command from the gray window
cmd.rotate("z", 30, "flexregion", camera=0, origin=rotationCenter)

hope that makes sense.
