[Chimera-users] Contour maps or step-gradient of volume map?

Hi, Is it possible to choose n levels of gray for a volume map? I'd like to make a known-thickness slice using clip, and then see that slice as a defined number of colors. I can kluge it by displaying the map 4 times at 4 contour levels, but is there a better way? thanks, Esther --- Esther Bullitt, Ph.D. Dept. of Physiology & Biophysics Boston University School of Medicine 700 Albany Street, Room W302 Boston, MA 02118-2526 Email: bullitt@bu.edu Telephone: 617-638-5037 Facsimile: 617-638-4041 http://www.bumc.bu.edu/phys-biophys/faculty/bullitt
