[Chimera-users] Help needed

[Bagchi, Angshuman]

Hi,
I am a student of IUPUI (indiana-University-Purdue 
University-Indianapolis). I would like to know how chimera can be used 
to select the amino acid residues of one chain of a protein, which are 
within a certain distance (say 10A) of another chain of the same 
protein.
For example, the pdb 1o6s has two chains A and B. I would like to find 
what amino acid residues of A chain of 1o6s are within 10A of B chain 
of 1o6s.
I am eagerly expecting a reply from your end.
Thanks
Ang
