Hi Kristin, My reply mainly echoes Tom's but I'm sending it anyway. 8-) Although that tool doesn't have a specific control for linewidth, you can do it by: (1) selecting the icosahedron mesh (Ctrl-click on it) (2) opening the Selection Inspector (click on the greenish button near the lower right corner of the Chimera window -- may have a magnifying glass on it depending on version -- or, choose "Actions... Inspect" from the menu) (3) in the Selection Inspector, which should be showing "Inspect Surface piece" near the top, change the "line thickness" value near the bottom Even though the lines are fatter, they are still flat (not "sticks"). If you wanted sticks instead of lines, don't bother with the above, and instead use the command "meshmol" to change the mesh surface into sticks: <http://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/midas/ meshmol.html> There may be a problem with "meshmol" in the current daily build (I just submitted a bugreport) but it works in the production release, 1.3. The Icosahedron Surface tool generates triangles. There is a related command "hkcage" that shows an icosahedron with pentagons and hexagons, and it includes an option for linewidth: <http://www.cgl.ucsf.edu/chimera/current/docs/UsersGuide/midas/ hkcage.html> I hope this helps, Elaine ----- Elaine C.

does anyone know if there is a way to increase the line thickness of the icosahedron cage in the higher-order structures option? Can't seem to figure it out. Thanks in advance. Kristin
