Hi Wally, You can use the setattr command, for example: setattr m stickScale 1.5 setattr m ballScale 0.5 http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/setattr.html http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/atom_spec.html#attrnam... Or, if you'd rather do something interactive/graphical: (a) select all molecule models (or at least one atom or bond from each) (b) open Selection Inspector by clicking button near lower right corner of the Chimera window or by choosing Actions... Inspect from the menu (c) Inspect "Molecule model" and change the ball scale and/or stick scale as desired These parameters are also in the individual molecule model attributes panels that can be opened from Model Panel, but it is too tedious to set the values individually for multiple models. Another possibility is to change the "New Molecules" Preferences to set those values as desired for subsequently opened molecule models (Favorites... Preferences, change to New Molecules category).

Hi All, This is probably a simple question, but the answer is eluding me. Say I have 20 models open. How can I globally change the stick scale and ball scale for all models. Thanks, Wally
