[Chimera-users] Volume color zones

[Thomas Goddard]

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.
