select by atom type in given model

31 Jul 2026

      I have three models of the same protein. How can I select C3 carbons in a given model? When I do

	sel #3 C3

I get an error "Expected a Keyword".  Therefore I have to select C3 in ALL models

sel C3

and then do

~sel #1,2

for example, which deselects in models 1, 2.

If I do "sel C3" and ctrl-click "in" model 1(only model 1 is visible), say, it deselects in all models.

Is there a way to just select all C3 in model 3 in one single  command? Is there a "keyword" for atom type (analogous to @ for atom names)? 
This would be very useful, for example, in command (cxc) files, where I wouldn't have to delineate all the models. 

(I suppose I could do ~sel #1,2,4,5,6,7,8 in a command file. This is ugly.)

Thanks
