Thanks Tom, and thanks very much to you and Elaine both for the tips re
using color zone with morph movies - interpolating the colors was indeed
where I was running into trouble and it now looks beautiful!
Regarding the animation tool, it would be really great if there was a
option to export a script directly from the animation tool to recreate the
equivalent movie, as the interface is very handy for visualizing how
everything fits together and one could then iterate and tweak the script -
maybe for ChimeraX?
