Hi Francois,
There is no formal XYZ file format definition.  Chimera reads the format as described in Wikipedia, which only allows for one molecule per file.

Dear list,

I can read one molecule fine in .xyz format using chimera.

However, if my .xyz file has several molecules (like a MD trajectory),
chimera fails to read it in.

Is there planned support for MD trajectories given as .xyz file?

I have chimera-1.16.
I shall test with ChimeraX very soon.

Regards,
F.
