[Chimera-users] command line > vol all surface level 0.1 colour gradient

[Elaine Meng]

Hi Dieter,
You need a separate "scolor" command for the coloring, in which you have to specify the model numbers of the surface to color and the volume that the gradient comes from (there is no "all" specification).  You would need a separate scolor command for each different volume being used to calculate the gradient.  For example

vol all style surface level 0.1
scolor #0 gradient #0 cmap rainbow
scolor #2 gradient #2 cmap rainbow

Syntax and options are explained in the "scolor" documentation:

<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/scolor.html>
<https://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/scolor.html#gradient>

You could find this with menu: Help... Search Documentation, e.g. searching for "volume gradient".

I hope this helps,
Elaine
