Hi Reza, There are several commands and tools that calculate atom-atom interactions and draw dotted lines. See menu: Select... Contacts (choose "Atomic"). This uses the Contacts tool, which you can also start directly from the tools menu (Tools... Structure Analysis... Contacts). <https://rbvi.ucsf.edu/chimerax/docs/user/tools/clashes.html> There is also Tools... Structure Analysis... H-Bonds. <https://rbvi.ucsf.edu/chimerax/docs/user/tools/hbonds.html> These are also available as commands: contacts, clashes, hbonds <https://rbvi.ucsf.edu/chimerax/docs/user/commands/clashes.html> <https://rbvi.ucsf.edu/chimerax/docs/user/commands/hbonds.html> You may want to take a look at the Protein-Ligand Binding Sites tutorial which covers some of these features: <https://rbvi.ucsf.edu/chimerax/docs/user/tutorials/binding-sites.html> If you mean you want to choose 2 atoms manually and draw a dotted line, just add a distance measurement. Ctrl-click one atom, Shift-Ctrl-doubleclick second atom, choose distance from pop-up menu, see selection context menus: <https://rbvi.ucsf.edu/chimerax/docs/user/selection.html#context> ... or, you can use the distance command: <https://rbvi.ucsf.edu/chimerax/docs/user/commands/distance.html> However, if you meant you want a 2D graph (not in the 3D window), sorry there is no 2D diagram of atomic interactions currently. I hope this helps, Elaine ----- Elaine C.

Hi,
I'm hoping this question wasn't asked before. Is there a way to draw a dotted line between interacting residues? This would be similar to the Chain Interface graph that shows interaction between chains. Thanks.
Best wishes, Reza
