[Chimera-users] Moving molecules independently in chimera

Hi David,
There are several different ways to toggle the "activation status" of  
a model,
i.e. whether the model can be moved or not.  This status can be set  
for each model.  Any of these ways can be used:

- if you are showing the Command Line (Tools... Favorites... Command  
the checkboxes next to the model numbers in the "Active models" line  
can be
used to activate/deactivate models.

- in the Model Panel (Tools... Favorites... Model Panel), the "Active"
checkboxes can be toggled to activate/deactivate models.

- the "select" command can be used, as described in

You might consider taking a look at the tutorials (Help... Tutorials).
Both of the beginner tutorials mention this issue (near the end of the
respective tutorial). When you  open both of your PDB files, by default
the first one you open will be model 0 and the second will be model 1.
I hope this helps,
