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 http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/atom_spec.html#hiera rchy

Hi, I opened two protein structures, say 2JIT and 4WA9 and they were partially

overlapped on the screen. How to move one protein so that they can be separated more? I can only move the two proteins as a whole but not individually.

Further, I would like to highlight one residue for a particular protein

and I could not find a way to first select a protein and then a residue.

Thanks, Jing
