P.S. Warren, there is still a problem with drawing CGO cylinders and sausages along the (1,-1,1) direction -- they don't appear unless you ray trace the image: As an example: load 1avv.pdb run draw_symops_cctbx.py draw_symops 1avv One of the three-fold axes originating at the origin does not show up. To test this I offer the following: #! /usr/bin/python from pymol.cgo import * from pymol import cmd """ draws cylinders in the directions: (1, 1, 1) (-1, -1, 1) (-1, 1, 1) (1, -1, 1) The last one won't appear, unless one of the directions is modified by a very small amount (e.g below using 30.000001 instead of 30.0) """ ax_1_yes = [ CYLINDER, 0.0, 0.0, 0.0, 30.0, 30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, CYLINDER, 0.0, 0.0, 0.0, -30.0, -30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, CYLINDER, 0.0, 0.0, 0.0, -30.0, 30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, CYLINDER, 0.0, 0.0, 0.0, 30.000001, -30.0, 30.0, 0.2, 0.0, 0.0, 1.0, 0.0, 0.0, 1.0, ] ax_2_yes = [ CYLINDER, 0.0, 0.0, 0.0, 30.0, 30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, CYLINDER, 0.0, 0.0, 0.0, -30.0, -30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, CYLINDER, 0.0, 0.0, 0.0, -30.0, 30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, CYLINDER, 0.0, 0.0, 0.0, 30.0, -30.000001, 30.0, 0.2, 0.0, 1.0, 1.0, 0.0, 1.0, 1.0, ] ax_3_yes = [ CYLINDER, 0.0, 0.0, 0.0, 30.0, 30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, CYLINDER, 0.0, 0.0, 0.0, -30.0, -30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, CYLINDER, 0.0, 0.0, 0.0, -30.0, 30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, CYLINDER, 0.0, 0.0, 0.0, 30.0, -30.0, 30.000001, 0.2, 1.0, 0.0, 1.0, 1.0, 0.0, 1.0, ] ax_3_no = [ CYLINDER, 0.0, 0.0, 0.0, 30.0, 30.0, 30.0, 0.2, 1.0, 0.5, 0.0, 1.0, 0.5, 0.0, CYLINDER, 0.0, 0.0, 0.0, -30.0, -30.0, 30.0, 0.2, 1.0, 0.5, 0.0, 1.0, 0.5, 0.0, CYLINDER, 0.0, 0.0, 0.0, -30.0, 30.0, 30.0, 0.2, 1.0, 0.5, 0.0, 1.0, 0.5, 0.0, CYLINDER, 0.0, 0.0, 0.0, 30.0, -30.0, 30.0, 0.2, 0.0, 1.0, 0.0, 0.0, 1.0, 0.0, ] cmd.load_cgo(ax_1_yes,'ax_1_yes') cmd.load_cgo(ax_2_yes,'ax_2_yes') cmd.load_cgo(ax_3_yes,'ax_3_yes') cmd.load_cgo(ax_3_no,'ax_3_no') If one clicks on the 4 objects one by one, you'll see that the "ax_3_no" object is missing one cylinder that is present in the others.
