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 ----- Elaine C.

Is there a command to scale sphere of a CPK rep?
Is there a command to save the current viewing transformation to a file and then read it back/apply it at a later time?
Thanks, Randy
