[Chimera-users] bond transparency as a function of length?

[Kersey Black]

Hi,

Very recent to Chimera.  Trying to set the transparency of a bond
to be a function of bond length in each frame of a trajectory.  
I have figured out how to define a transparent color, and 
now I am imaging the solution might use something like range color
to vary the blending of the opaque version of the color and the 
fully transparent version based on distance, with the distance being 
determined as a per frame attribute of those atoms, but someplace around 
here I am lost.  Any hints, links or suggestions would be very much 
appreciated.  

Cheers, KB
