Hi Aritz, For adding hydrogens: see command "addh" http://rbvi.ucsf.edu/chimerax/docs/user/commands/addh.html
For adding an individual atom (start structure) or adding/changing atoms connected to an existing molecule (modify structure): Build Structure tool (in menu under Tools... Structure Editing) http://rbvi.ucsf.edu/chimerax/docs/user/tools/buildstructure.html
For adding "markers" (balls or spheres, but implemented as atoms): Marker Placement tool (in menu under Tools... Volume Data): http://rbvi.ucsf.edu/chimerax/docs/user/tools/markerplacement.html
I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Dear ChimeraX team, Maybe it is a silly question but I have been trying to add atoms on ChimeraX but I have not found the way, is there any possibility? I need to plot a channel on my protein but I do not manage to do it without that. Thank you in advance. Best wishes, Aritz
