Dear Colleagues, I have tried to open several local *.pdb files, but in each case I got the error: "Opened PDB data containing 0 atoms, 0 bonds and 0 coordinate sets", and a series of warnings (for each lines of the files) and ChimeraX doesn't show the structure. I have also tried different versions of ChimeraX (0.1/0.5 and even alpha releases, recently I'm using 0.5 under Ubuntu 16.04). I can open any online files (*pdb,*mmCIF) from the RCSB database, however if I download the same file, I got the above mentioned error message, so I have absolutely no clue to resolve the problem because I suppose this isn't related to pdb format issues but a bug can be somewhere in the softwere. I am really impressed by the visualization capabilities of ChimeraX so please help me if you can. Yours, Attila
