Re: [Chimera-users] UCSF Chimera Ribbon Question
Hi Alex, The problem is not the ribbon style (and you don’t need supersmooth, simply smooth will do) but the “subdivision” graphics quality, which has apparently gotten set to some abnormally low value. Your ion isn’t particularly spherical in the image either, because this parameter also affects atom and bond display. See Tools… Viewing Controls… Effects, “subdivision” in the lower right area of the dialog. The factory default is 1.5 whereas your image looks something like 0.1. You can also control this value with the “set” command. This is discussed in the “Image Tips” under smoothness <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/print.html#tips> …as well as the Effects and “set” documentation <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/sideview.html#effects> <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/set.html#subdivision> For future reference, we recommend sending questions to chimera-users@cgl.ucsf.edu (CC’d here) to better ensure that you get an answer.

Elaine, I'm having a little difficulty viewing ribbon models. I'm not sure what I did exactly, but I every time I open up Chimera, the default setting is this (see attached photo). This looks like a flat representation of the ribbon, but it's actually the supersmooth representation. I've tried double-checking the Cross Section in the Ribbon Style Editor, but everything looks normal (see attached photo). Can you help me with this? Sincerely, Alex Yorn
P.S. Remember to click Save on the Effects dialog after you change the value, so that next time you start Chimera it won’t be crazy again! Elaine
