[Chimera-users] Regarding backbone images for protein structures

[Elaine Meng]

Hello Saurabh,
Starting with Chimera 1.4 the default initial display of a molecule is  
nicer:  ribbons instead of all atoms.  However, you can get all atoms  
shown initially if that is what you prefer.  If you want that all the  
time, just change your preferences (Favorites... Preferences, go to  
"New Molecules" category, set "smart initial display" to false, click  
Save).  If you just want it sometimes and you are using the "open"  
command inside of Chimera, use "open noprefs."  Or, just hide the  
ribbon after you open the structure if that is what is bothering you,  
or use the all atoms Preset.

This is not a bug.  This change and how to circumvent it (as included  
above) are described in the 1.4 release notes,
<http://www.cgl.ucsf.edu/chimera/docs/relnotes/1.4.html>

I hope this helps,
Elaine
