Re: [Chimera-users] Volume color zones

Hi Hernando, Elaine's suggestions about how to color multiple volume zones is the way to go. It is currently not possible to color separate regions of the map in separate steps -- they all have to be colored in one use of the Color Zone tool. The technical reason for that is that Chimera automatically updates the coloring if you change the volume surface, for example, by changing the contour level. If coloring in several steps were allowed Chimera would need to remember the sequence of colorings you applied. This makes the code more complex. Remembering the sequence of coloring steps would also be needed for saving Chimera sessions. I'll think about whether the extra complexity of the code is worth the added flexibility. Tom
