As you can see, clicking on the Origins command button brings up yet another grid, similar to those used for the Processes and Reactions commands. As before, the symbol of the featured nuclide (i.e., the one selected in the Main form's window) - in this case Co59 - is in the center of the grid.
This allows you to explore candidate decays or reactions that can, in principle, yield the featured nuclide (although many of them – perhaps all – may be impossible or at least energetically unfavorable). Clicking on a box will display the properties of the parent nuclide (in the case of decays) or the target nuclide for the specified process or reaction. Note that ALL of the decays and processes shown will, in principle, produce the featured nuclide.
