I have an incomplete pdb crystal structure of a homohexameric protein
containing six ~25AA tails.  In the incomplete model, two of these
six tails are complete (A and F)  and the other four are truncated
at various positions (B,C,D, and E).  I have used the either the A
or F complete tails as templates and generated appropriate length
segments to compleate each of the truncated B-E tails by selecting the
appropriate residues and saving the selected atoms as a new PDB. 
Currently, I have all six tails completed and saved as a single
PDB.  I would like to use the Bond command to covalently link the
extended chains, but my single PDB is segregated into models 1.1, 1.2,
1.3, 1.4, and 1.5.  When I use the Bond command as follows "bond
#1:504.b@c & #1.3:505.a@n", I get an error that only one atom is
selected.  Does Chimera consider #1 and #1.1 to be different
models?  If so, how can I merge these 5 models into one to allow
me to create the bond?<br>
