I have several structures I would like to superimpose and graphically display
with a ribbon backbone. Quite simple, really, and a variety of programs
will readily perform this task.
However, I would like to blend the colors of the superimposed backbones,
such that when the ribbons of the different structures merge,
their color merges. For example, if I display two similar proteins with
a blue ribbon and a red ribbon, I would like the portions of the ribbons
that occupy the same space to be assigned a color of purple with a
brightness/saturation approximately twice that of the individual protein's
ribbons.
My question is:
Which software will do this? Insight and Midas don't appear to
have this ability. Does Quanta? Is there another program, such
as O, Grasp or MacroModel that does? Am I wrong and can Insight
do this task?
Thanks for any help.
