<br>
I don't know if more than one chain can be associated with a
sequence in Multalign Viewer. The documentation says<br>
<br>
"
<meta http-equiv="content-type" content="text/html;
charset=ISO-8859-1">
A structure (even if it has multiple chains) cannot be associated
with more
than one sequence, but a single sequence can be associated with
more than one structure."<br>

<br>
That doesn't really say whether multiple chains of a single
structure can associate with a sequence, only that multiple
structures (different PDB models) can associate with the same
sequence. So I tried it as I'm sure you did and I was not able to
make it associate more than one chain (I used groel 1grl) with the
same sequence in a multiple alignment. When I load the structure
it associates chain A but not any of the other chains. Then if I
use MultAlign Viewer menu Structure / Associations... to associate
chain B with the same sequence then it seems to lose the
association of chain A. At least when I select residues on the
sequence, only chain B on the structure has residues selected.<br>
<br>
I'm forwarding this to the Chimera list since Elaine Meng or
Eric Pettersen will have a better answer.<br>

Hi,<br>
I am wondering if this is a bug or limitation in Chimera, or if
I am missing something. I have a molecular model of F-actin, with
many identical chains. Using the Multialign Viewer, it appears
that I can only do a 1 to 1 mapping of a single chain to a single
sequence. How can I map 10 identical chains to one sequence?<br>
Regards,<br>
Ed<br>
