Hi Guizhen, Here are a few more details. This is kind of tricky because Chimera focuses on 3d images, not 2d plots. Use volume dialog menu Features / Planes to show one plane of your map, switch to surface style, use volume dialog menu Tools / Surface Color and color the plane by "volume data value”. Now we make the contour lines by making a copy of the map, volume dialog menu File / Duplicate, show the same plane, set style to Mesh, turn off the “Cap high values at box faces” option (Features / Surface and Mesh Options), add more contour levels using ctrl-click on the histogram, increase line thickness (Featues / Surface and Mesh Options), color all levels black (command "color black #1”). Since the planes are at exactly the same level the contour lines are probably hidden. To fix this move the contour plane slightly forward with command “move z 1 model #1 coord #1” (move map #1 by 1 Angstrom along the z direction of the coordinate system of map #1). I did this on a ryanodine receptor map, emdb 5014 (plane 89). Here’s the result. Tom On Nov 5, 2014, at 10:36 AM, Elaine Meng <meng@cgl.ucsf.edu> wrote:
Hi Guizhen, I don’t know of a way to make a figure exactly like yours, with colors between black lines. However, I know how to show a slice in which the contour lines themselves are colored, as in the attached image. To make that image, I used the “Planes” feature in Volume Viewer, with multiple contour levels and other specific settings as described in this previous post:

Hi, How can I get multi contour lines like attached figure? Thank you. Guizhen
