[Chimera-users] Merge PDB Question

[Jared Godar]

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 at c & #1.3:505.a at 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?

Thanks,

Jared
