[Chimera-users] thermal ellipsoids

[Michael Day]

Eric,

For small molecule/high resolution work an ortep type representation  
would be as shown below (all three clips are from the same molecule).  
The ellipsoid, it's three axis and a shaded octant.

I understand the octant is the hardest part. As you can see the  
addition of thermal ellipsoid information adds a lot to the rendering.  
My small molecule users are very excited about the addition of thermal  
ellipsoids to Chimera and we're doing hundreds of structures per year.



Cheers,
Mike

Hi David,
	I guess my question is how important is fancy5 and fancy6?  Those  
will be the hard ones for me to do.  Keep in mind that "display of ...  
major ellipses" will look like fancy3 except that you will be able to  
see the arcs of the major ellipses without using a transparent  
ellipsoid.  The other "fancy modes" are not difficult to do.
