Hi Eric, Thank you very much for the ellipsoid script! I really appreciate your help and I think this will do the trick for now. I have been learning some python on my own and I was wondering if you have some good beginner examples of scripts for making geometrical shapes, changing size and color, orientation, etc. that work in chimera.

Hi David, You can show cones, arrows, boxes, and a variety of simple geometric shapes by opening a BILD format file in Chimera: BILD format. It may be a little awkward having a script write a temporary file, so instead you can use a StringIO object, as described here: [Chimera-users] BILD object question You can also use the 'shape' command to draw spheres, cylinders, and icosahedrons. You can run any Chimera command from Python by using Chimera's 'runCommand' function, e.g.: from chimera import runCommand runCommand("shape sphere center ligand color dodger blue radius 25") Feel free to ask more questions! --Eric
