[Chimera-users] automating a task

[Elaine Meng]

Hi Dieter,
You can use the command "scolor" in a Chimera command script:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/scolor.html>

... and for gradient specifically:
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/scolor.html#gradient>

For example, something like this for volume #2 (see docs for other options) and then repeat for all other models you want to color the same way: 

scolor #2 gradient #2 cmap rainbow

Generally  if you want to know if there is a command equivalent for a tool and what that command is, just click the Help button on the tool dialog.  The help page for that tool will say something like "is also implemented as the command [blah]."

For example, it's in the first few paragraphs on the Surface Color page:
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/surfcolor/surfcolor.html>

I hope this helps,
Elaine
