[Chimera-users] pseudo bond reader in command line

Yes - that helps a lot.  I think option B will be best.

I think this will get me the panels I need to make the movie….I may need some more guidance to put it all together, though!

My strategy is to build a scene, then record some frames, then build the next scene, then record frames (for at least 5 panels).  Can I do this in one script by using the line command "movie"?  Is there a better way?

Thank you so much for your quick response.

Click the group name on the left and "attributes..." on the right side of the PseudoBond Panel to see what things are available for changing with the command "setattr" -- the top section has group attributes ("g" in setattr command) and the bottom section has individual pseudobond attributes ("p") in setattr command. If you hover the mouse over something in that dialog, balloon help will show the attribute name to be used in the setattr command, as well as its possible values.
