##### The "Atom(s)" menu

The "Atom(s)" menu [Fig. 5.5-a] offers to configure some visual features related to the chemical species in the model. This menu contains shortcuts for some the properties that can be adjusted using the more advanced "Atom(s) configuration" dialog, and that can be opened using any of the "Advanced" buttons in the menu. The "Atom(s) configuration" dialog is presented in figure 5.6:

The window contains a notebook with 3 tabs:

• (a) The "Display properties" tab: to adjust chemical species colors, atomic labels, and depending on the model style:

• Ball and sticks: atomic radius

• Wireframe or Points: point size

• (b) The "Label properties" tab: to adjust the aspect of the atomic labels.

• (c) or (d) The "Atom(s) selection": to search for atom(s) in the model. If the model contains less than 10 000 atoms the entire list of atoms is displayed (c), otherwise it becomes too complicated to display and a search engine is proposed (d).

##### The "Bond(s)" menu

Via the "Bond(s)" menu [Fig. 5.5-b] it is possible to adjust the bond cutoff(s), and depending on the model style:

• Ball and sticks: bonds radius(ii)

##### The "Clone(s)" menu
For the "Clone(s)" menu to be activated two conditions must be fulfilled: to use PBC, ie. the model must have a periodicity, and, for such bonds via PBC to exist. If both conditions are met, then the first button of the menu to "Show/Hide Clones" will be active and it becomes possible to show or hide the clones.
If the clones are visible then the two "Atom(s)" and "Bond(s)" submenus will be activated as well. These menus are reproductions of the upper level "Atom(s)" and "Bond(s)" menus, and windows, but dedicated to the clones, this allows to make the clones even more distinguishable in the 3D representation.
