Atoms at Cursor

Dialog Box - called from: click in graphics window

When a drawing is displayed in the ATOMS graphics window, you can identify generated atoms by clicking with the mouse. Generated atoms can thus be marked for non-plotting and later deletion (see Deleting Atoms). If molecules have been located or fragment are present these are also identified.

A mouse click is judged to be "on" a given atom if it is within that atom's radius of its center point. If the atom in question has zero or negative radius (see the Revise Atom dialog in the Input1 menu for the significance of non-positive radii), then the default radius, set in the Preferences dialog in the Settings menu, is used.

The click point may actually be "on" more than one atom; all atoms which project onto the plane (x = 0) within the specified distance of this point are identified, not just the one which is visible at this point. In this case, the Atoms at Cursor dialog comes up, giving a list of the atoms, from foremost to rearmost. Select the desired atom, and click on the View/Revise Atom button. This brings up the Generated Atom Data dialog for that particular atom. If the click point is only on one atom, the Generated Atom Data dialog comes up directly. If the click point is not on an atom, you get an alert to this effect.

The atom(s) which have been identified may be marked by outlining with a contrasting color - see the Preferences dialog in the Settings menu.
