Hi Ahmad,
I do not have this problem when I just open two structures and save them as a single PDB.  When I reopen the saved PDB it shows all the secondary structure of both structures.

When you save make sure you are saving all of the atoms (do not use options “Save displayed atoms only” or “Save selected atoms only”).  Other than that, I don’t have any idea what happened with your file, without seeing that file.  You could send (attach) it to e-mail.  You could send to just me if you don’t want to put it on the list.

> I don’t what process you used to save the structures in a single file, so I don’t know what went wrong.  All I can tell from your images is that in the bottom image, some of the copies do not have secondary structure assignments, and that is why they show up as thin “coil” ribbon instead of the wider helix and strand ribbon.  It might be that something is wrong about the format of your single file, or that some of the backbone atoms are missing.  If you don’t think there are missing backbone atoms, you could try command “ksdssp” to reassign helix and strand, but the assignments probably won’t be exactly the same as from the original PDB file.
