Hi Kanika, you can do this with the "rotate" command, without any additional script (like Michael already suggested). Note: for a dimer the the center of mass does not yet define an axis, my example uses an arbitrary axis on the mirror plane between the monomers.
# get some homodimer fetch 3p8d, dimer, async=0 # create copies of one monomer create copy1, dimer and chain A create copy2, dimer and chain A create copy3, dimer and chain A create copy4, dimer and chain A # orient will put the (unweighted) center of mass in the middle of # the window and both monomers on the camera x-axis orient dimer # now rotate around the z-axis in camera space rotate z, 60, copy1 rotate z, 120, copy2 rotate z, 180, copy3 rotate z, 240, copy4 Have a look at: http://pymolwiki.org/index.php/Orient http://pymolwiki.org/index.php/Rotate If you need more fine control, go for Troels suggestion. There are also center-of-mass scripts on the PyMOLWiki.
