Hi Elaine,

Thank you very much for your detailed explanation.

We finally got it working specifying a cmap for the scolor and setting same values for color key.

Cheers, Pablo.

Hi Pablo, Unfortunately “scolor” lacks a “key” option. Some other color-by-value commands (coulombic, rangecolor) have this option, which automatically starts the Color Key dialog and fills it in with colors and values. However, it is similar to using the Surface Color dialog’s option to create color key, in that you still have to use the mouse to set color key location and dimensions in the window, and manually edit the value labels in the Color Key dialog if you want to round them or omit some of them from the display.

For non-interactive, completely scripted Color Key drawing, you would have to use the “colorkey” command with explicit values and colors. It does not “know” about your data, so you’d have to determine the appropriate values programatically.

I hope this helps, Elaine

Sorry! I realized that I created the color key through the "Surface color" tool.

So, by default there is no color key. I think now this is not doable unless I set the color key in the script.

Dear all We have this simple script to open a volume (#0) coloured using values from a second volume (#1):

open betaGal.mrc open extra/MG_Chimera_resolution.vol volume #1 voxelSize 3.54 vol #1 hide scolor #0 volume #1 cmap rainbow reverseColors True

For scolor command we are using a volume. https://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/scolor.html#volume

It would be nice to achieve something like this at start up (note the color key is based on the volume):

I've did it dragging the mouse over the canvas while "Color key" utility is open.

And, is there a posibility to round up the values. Some kind of: Psaudocode: Give the resulting color key for each round values display the color key

I guess that if there is a way to get the color key, then rest can be done through commands. Cheers, Pablo.
