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

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
(2) superimposing similar structures
(3) using movement commands (move, turn, etc.) with “models” keyword to move
only specific models

There are many ways to act on individual residues:
(1) selecting them with Ctrl-click on the structure
(2) selecting them in the sequence window (menu: Favorites
(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,
