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 From: Evan Kantrowitz <evan.kantrowitz@bc...> - 2007-08-09 21:37
Attachments: HTML-Email.html      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.
