Although I haven't used EMAnimator, you can set the center of rotation within Chimera using the Set Pivot action: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/menu.html#actpivot There's also Tools/Movement/Rotation, and lastly, you can edit structures to insert artificial points at extreme high/low XYZ locations, which will in effect manually set the center used via the 'center of models' option. I wouldn't recommend the last option unless you have a good reason to do so, but it does work. Jonathan

Can anybody tell me how to use EMANIMATOR to make a movie of a molecule rotating. If I use the spin option, it uses the axis (0 1 0) but my molecule is not center at 0 0 0. Is there a way to fix the rotation center to the center of the molecule, or to the center of the view? Thanks
