[Chimera-users] xforms, cpk scale

[Elaine Meng]

Hi Randy,
(1) The CPK representation uses the VDW radii.  Several ways to  
change the VDW radii are listed here:
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/vdwrad.html

and of these, the command way is to use "vdwdefine":
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/vdwdefine.html

(2) If you remain within the same session ("later" means you haven't  
quit Chimera in between, or if you have, you saved and then restarted  
a session), "savepos" and "reset" can be used to save collectively  
the model transformations (and scale, and clipping plane positions),  
and restore them:

http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/savepos.html
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/reset.html

If you want to quit Chimera in between and not save a session, see  
"matrixget" and "matrixset":

http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/matrixset.html

The matrices would just specify model rotation/translation and not  
the clipping plane positions or scale.
I hope this helps,
Elaine
