[Chimera-users] fitting a protein inside an EM reconstruction

[Elaine Meng]

Hi Jayant,
Selecting something is not the same as making it movable.  Selecting 
something makes Actions menu items apply to it.  If you want to make 
different models movable/unmovable, use the "Active" checkboxes in the 
Model Panel (Favorites... Model Panel), or various "activate" functions 
in the right side of the Model Panel, or the small checkboxes under the 
Command Line (Favorites... Command Line).

These activation methods determine which models can be moved with the 
mouse or with movement commands like "move" and "turn."

As Tom said, however, the fitting tool requires atoms to be selected.  
Even if only a few atoms are selected, the fitting will move the entire 
model containing the atoms, but maximize the density values at the 
selected atoms.

I hope this helps,
Elaine
