[PyMOL] B-factor putty tube representation

Hi,

I would like to define the radius of the cartoon putty on absolute,
rather than a relative scale.  Is there any way to do this?  If I am
comparing rmsd, for example, I would like every image to be
representative of the true RMSD differences, rather than being a unique
relative scale for each comparison.

I notice that others have also asked about this in the past, but I did
not see a response on the Pymol-Users Email Archive.  Maybe there are
new features in 1.1 that address this?

[PyMOL] putty tube representation

I am making tube representations as a comparison between two 
structures. I have the rmsd in the b-factor field.
1) If I do a putty representation it works. How does the program 
decide on the width variation of the tube?
2) How can this be reset?
I want to do this so when I compare two different rmsd plots the 
width of lets say 1 rms is the same in both figures.

Any help would be apprecipated.
