[Chimera-users] failing to open saved PDBs

Hi Joe,
A multi-model PDB should open fine; this format is used for NMR ensembles from the PDB, e.g. fetch 1g1p and see what you get.  Not sure what you meant by “behave like a single structure,” but you can see how it is supposed to behave by opening that example or any other NMR ensemble from the PDB.

I can only say to look at the options carefully when saving (could be something like “save selected atoms only” was turned on but nothing was selected).  Also, after trying to open the file, you could use menu: "Presets…. Interactive 2 (all atoms)" in case the atoms were automatically hidden for some unknown reason.  

However, it’s basically impossible for us to tell what’s going on without seeing your file, either sent to this list or attached to a bugreport set with menu: Help… Report a Bug.
