Hi Yasser, Chimera does not have a command to do this. In Chimera you could do it with menu Tools... Structure Editing... Build Structure, the "Start Structure" atom option. I don't know python, so I can't give details on that. <https://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/editing/editing.html#start"> Other possibilities in Chimera are to manually create (with a text editor) a PDB file or marker file and then open it. If you use ChimeraX instead, there is a "build start atom" command to do it. <https://rbvi.ucsf.edu/chimerax/docs/user/commands/build.html#start> I hope this helps, Elaine ----- Elaine C.

Hello,
How can I create an atom object, with a given xyz coordinates, via command or python?
Thanks in advance,
