CCL: How to select residues

 Sent to CCL by: "Nicolas  Ferre" [nicolas.ferre]^[univ-provence.fr]
 Dear CCL'ers,
 I'd like to select and save a small part of a pdb file. Actually I want to
 select all the residues inside a given sphere centered on an amino-acid.
 I know I can use RasMol's "select within (expression)" but it results
 in selecting some atoms, not whole amino-acids. Obviously I can look at the
 selection using "show selected" and copy/paste every amino-acid label,
 but this is a rather tedious task.
 Alternatively I can use Molden, but as far as I known, it only shows the
 corresponding amino-acids without giving the possibility to save them in a file.
 If I am wrong, please correct me. If not, do you know any free software allowing
 such residue selection and saving ?
 Best regards,
 Nicolas
