[Chimera-users] selection of a specific region from different chains

[Elaine Meng]

Hi Andy,
if the numbers are different in the different chains, you can also use  
a command like

sel :100-200.a,235-280.b,298.b,112-194.c

(residues 100-200 in chain A, residues 235-280 and 298 in chain B,  
residues 112-194 in chain C)

There are examples of command-line specification on the back side of  
the Quick Ref (PDF file):
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/quickref.pdf

and full documentation of command-line specification is here:
http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/frameatom_spec.html

There are additional ways, more complicated to explain.  If you change  
selection mode to "append" (menu: Select... Selection Mode... append)  
then selections such as with the "select" command or by dragging in  
the Sequence tool will be accumulated instead of replacing each  
other.  I recommend changing back to "replace" afterward to avoid  
later confusion.  Also, the selection mode does not apply to selection  
with the mouse in the graphics window.

Best,
Elaine
