[Chimera-users] select a specified residue

[Elaine Meng]

Dear Zhengfeng
The simplest is to use the command line.  There is a whole “atom specification" language for selecting or specifying certain models, chains, atoms.  For example:

select :200
select #0:200.A

The first example selects all residues with number 200, the second example selects residue 200 in chain A of model 0. See “atom specification” description and many examples:

To learn more, you could try the “getting started” tutorials:
<http://www.rbvi.ucsf.edu/Outreach/Tutorials/GettingStarted.html>
<http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/tutorials/getting_started.html>

You can also show Sequence from the Favorites menu and select with the mouse in the sequence window.

I hope this helps,
Elaine
