Hello,

Will you suggest an alternative error message that is not misleading or is more informative for this case?
The fact that the number of atoms is not the same always suggests that a previous file is loaded and its data (number of atoms) is not compatible with the file being loaded. VMD didn't "know" that you wanted to load a new molecule.

Ah. I see. The problem isn't in the file. Now I understand: I had loaded 3zoo prior to 1oxy and had overlooked to set the "Load files for:" selection in the File Browser to "New Molecule". When any file is then loaded "for" 0:3zoo the error occurs reproducibly. It's just that the error message pointed me into a completely different direction ...

Bottom line: user error and misleading error message.
Thanks,
Boris
