Dear all,

Please keep in mind that my background is neither in computer programming, nor in structural biology, hence my lack of understanding of basic concepts as the structure/format of a PDB file.

I started with a PDB file from the PDB database. I opened it in PyMol, and deleted the parts I did not need and saved it as a PDB. Then, I loaded it into Chimera and prepared a symmetrical molecule with C9 symmetry, and again saved it as a PDB. When I opened that with either Pymol or ePMV in Blender, I only saw one of the monomers. Then, I went back to chimera, and combined all models listed in the PDB into a single model, and saved it as a PDB. Now, if I import it to Blender with ePMV, I see nothing if I do not choose lines or PointClouds. In other words, I cannot import it as a cartoon model, although Chimera and PyMol have no problem displaying it as a cartoon.

Any suggestions to fix this?

Thank you.

Edit: I just saw that in the terminal this is displayed for all chains: "no secondary structure set for chain: n !"

The problem has been fixed, for some file that dont have the secondary structure information the conputation didnt occur.
Now we can force the secondary structure computation at loading time using PROSS
