[Chimera-users] Presets and multiple structures

[Eric Pettersen]

On top of Elaine's good suggestions, there's a horrible kludge that  
you could possibly use.  Before you open your additional structure,  
save a session.  Then open your new structure, position it, and close  
the other models.  Apply your preset.  Restore the session you saved  
and when Chimera asks you if you want to close existing models say no.
