Atom selection

[Feng Cui]

Hi all,

I have a question with regards to selection of atoms in X-plor.

I have a protein of 60 residues. For the CA atom of each residue, I intend to 
select CA atoms that are within 7 angstroms of the CA atom. I know it is easy 
by using "for id" loop. Is there any way not to use "for" loop?

Thanks.
