Dear Mingjun, Oh, now I see -- you want a color key! Yes, you can do that in Chimera: choose Tools... Utilities... Color Key. In that dialog you can set the colors and the value labels. You can click and drag with the mouse to draw the key in the Chimera window. If you need more text, you can add it with 2D Labels, which is another tab on the same dialog as Color Key. Here is the full description: <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/2dlabels/ 2dlabels.html#colorkey> and here is an example image with both Color Key and 2D Labels: <http://www.cgl.ucsf.edu/chimera/feature_highlights/2gbp-bfactor.png> You would add that stuff while you are still in Chimera, and then when you save the image, it will be included. You might also be interested in this page on "tips" for making images: <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/print.html#tips> I hope this helps, Elaine ----- Elaine C.

Dear Professor, Thanks so much. I am the first time to use Chimera so I am sorry that if my questions seem to be too simple... Sorry that I didn't describe my question clearly in last post. I had got the figure of 20 frames which are colored by using the command "rainbow models red, blue". Then I saved the figure with the file name a.png. Now I'd like to use the color range to denote each frame in the paper, e.g. color range from red to blue gradual changes corresponds to colors used by model 1 to 20 in the saved figure. Since I don't know what is the name it is should be called in English language, I send you an example in the attachment. Many thanks. Mingjun
