[Chimera-users] select all side chains

Dear Ming Zhou,
There are a few different ways, but one is to select protein atoms that are NOT backbone, e.g.:
select protein & ~@n,ca,c,o
Another way is with the command:
select side chain/base.without CA/C1'
... or the shorter version:
select without CA/C1'
This is because you can use various Select menu entries exactly as they appear in the menu to specify atoms in the command line. The menu includes "Select... Structure... side chain/base... without CA/C1'" For more details on which menu items can be used in this way, see the section on "built-in classifications":
If there was also DNA/RNA in the structure, you could then use an additional command to de-select just that part:
~select nucleic acid
There is also a "with CA/C1'" (instead of "without") for example if you wanted to use the selection to display the side chains connected to ribbons instead of floating in space.
I hope this helps,
