<div>Hi, Elaine:</div>
<div> </div>
<div>Thanks for your kind reply that is very informative.</div>
<div> </div>
<div>Eventually, I found the solution to mapping the epitopes to reference/merged protein which is combined by text editor. Please see the enclosed results analysed by "Blast 2 seqs" (HTY_HA_B2Seq).</div><font>
<p>I spent a couple of days to study the docs of "Chimera". Finally , I came out of the command lines to map epitops to protein structure:</p>
<p>open 3LZG<br>split #0<br>preset apply int 3<br>col magenta r #0.1:322-330<br>col magenta #0.2:1-11<br>=========================</p>
<div></div></font>However, I found a very unexpected region which is colored by the epitope segment. See the "red question marks" in the PPT file (HTY_HA_Chimera.pdf)<br>
<div>Thanks again,</div>

Are the chains in two different PDB files or in the same PDB file, and why do you want a single chain in Multalign Viewer? Did you just want one chain stuck on the end of the other, or mixed together somehow?<br>
<br>You may be able to do what you want without merging any chains. You can just show the sequence of each chain in a separate window (Favorites.. Sequence), and both of those will automatically interact with your structure: if you highlight some residues in the sequence window, the corresponding part of your structure will be selected and vice versa.<br>
<br>If you really need a merged single chain, the details depend on what you have to start with. Multalign Viewer editing does not allow merging chains directly, so you might have to do text-editing manually (in your favorite text editor outside of Chimera).<br>
