Hi Glenn, Although we plan to have user-defined presets in the future, currently there is no reasonably user-friendly way to customize them. As a stopgap, if there are a few commands that generate the display you want (and you could start with a preset command), you could: - put them in a command file; simply opening the command file in Chimera would execute it - alias some word like "mypreset1" to those commands all strung together with semicolons, then later you would only have to type the command "mypreset1" http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/alias.html You can have a command file automatically read at Chimera startup. This is specified in the preferences: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/preferences.html#Midas You would only put the alias commands there, not the display commands themselves, since you want to control when those commands are executed (and usually at startup no structures have been opened yet anyway). There is also a New Molecules section of the preferences in which you can control how structures are displayed when they are first opened: http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/preferences.html#New% 20Molecules However, the New Molecules options are rather limited compared to what you can do with commands. There is nothing about disulfide bonds, for example. I would be happy to provide more detailed help with any of this if you would like. Best, Elaine ----- Elaine C.

Hi Folks, Is there a way to edit the Presets to include additional protein features? Specifically, I work with quite a few disulfide rich proteins and it would be great to select the Preset Interactive 1 and have it automatically draw Cys side chains with disulfide links. Many thanks, glenn

Hi Glenn, Brief experimentation suggests this possibility (show command line with Favorites... Command Line): alias mypreset1 preset apply inter 1; sel disulfide; sel up; disp sel; ~sel Then you can just execute the shorter command: mypreset1 Many variations are possible, like additionally coloring the cysteines. If all cysteines rather than just the disulfide-bonded ones are desired, it is even simpler: alias mypreset1 preset apply inter 1; disp :cys Best, Elaine ----- Elaine C.
