Thanks Elaine. These links are very helpful.

Hi Jing,
For an overview, you might want to try the “getting started” tutorial --
moving separately is mentioned in “models and model status,” and specifying
individual residues is covered in “selection with the mouse” and
“command/target”: 
<http://www.rbvi.ucsf.edu/Outreach/Tutorials/GettingStarted.html>

However, I’ll try to list the ways briefly in this message.

There are many ways to move structures separately:
(1) “freezing” (deactivating) some structure(s) and moving the others with
the mouse
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/mouse.html#activedef>
(2) superimposing similar structures
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/superposition.html>
(3) using movement commands (move, turn, etc.) with “models” keyword to move
only specific models
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/move.html>

There are many ways to act on individual residues:
(1) selecting them with Ctrl-click on the structure
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/selection.html#pickselect>
(2) selecting them in the sequence window (menu: Favorites
 Sequence)
<http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/multalignviewer/f
ramemav.html>
(3) just specifying the residue(s) directly in a command, for example:

color red #0:325.A

 to color residue 325 in chain A of model 0 select #1:45.A,55.B 
 to select
residues 45 in chain A and 55 in chain B of model 1

I hope this helps,
Elaine
