Thanks, it works fine.
Now I just need to remove all the hydrogens from the PDBs and make sure the files ends with TER and not END.

To average the structures in Chimera, you need to open them as a trajectory with the MD Movie tool (in menu under Tools… MD/Ensemble Analysis). This can be done even if they are separate PDB files but they would have to meet certain naming conventions; see the multiple-files PDB option in the “Startup and Input” section of the MD Movie manual page:
So you might need to rename your files. Also I believe they would need to each contain the same set of atoms.
Once they are loaded as a trajectory, then see the “Structure Averaging” section of the manual page linked above.
I hope this helps,
