Thanks. When I try to color a different part of the map, it removes the first color. How can I save the colors to the map? P.s. I use atomic models for the coloring.

Hi Ahmad,
There’s not really that many steps to it.  You just need to select the markers and then use the Color Zone tool.  There is a little more description here
<http://www.rbvi.ucsf.edu/chimera/data/tutorials/volumetour/volumetour.html#colorzone>

...and in the Color Zone manual page:
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/colorzone/colorzone.html>

As mentioned in that page, you can also do it with the “scolor” command “zone” option.

I hope this helps,
Elaine
