[Chimera-users] "extended" Zone specifier

[Elaine Meng]

Hi Francesco,
You can do that with commands.  For example, here is the command to  
select residues in model #0 within 4 angstroms of
residues 20,30-40,55 of model #1:

sel #0 & #1:20,30-40,55 z<4

or you could use "za" instead of "z" for an atom-based instead of  
reside-based cutoff.
