[Chimera-users] Volume surface colors

[Thomas Goddard]

Hi Will,

   Here's a Python script that will change a volume color:

from chimera import openModels
from VolumeViewer import Volume
for v in openModels.list(modelTypes=[Volume]):
     v.set_parameters(surface_colors = [(1.0, 0.0, 0.0, 1.0)])
     v.show()

You can do the same thing more easily with a Chimera command and you can 
put such commands in a file (suffix .cmd) for Chimera to execute (by 
opening the file).

	volume # color plum

This colors all volume models as plum color.  If you wanted a specific 
model you would use for example #2 instead of #.  The notation # means 
all models.

You could also run this Chimera command from Python.

from chimera import runCommand
runCommand("volume # color plum")
