Please see the documentation on how to specify atoms in the command line. It includes several examples. <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/midas/frameatom_spec.html> Of course it depends what is in your input file. If there are two residues with the same number, it is a problem with your input file, unless they are in different chains. You can also include chain in the description, for example ":165.a@ca" for CA atom in residue 165 of chain A. You can also choose the two atoms from the screen with Ctrl-click, Shift-Ctrl-click and then use command "distance sel" Elaine ----- Elaine C.
