The Compounds_Tracker.json file stores chemical and thermodynamic information about the constituent elements and competing compounds. The data is organized as shown in the left column of Figure . The Defects_Tracker.json file contains total energy information of defects in materials. The total energies and finitesize corrections are recorded for each charge state of each defect as shown in the top-right column of Figure . Currently, finitesize corrections are not directly computed by VTAnDeM and are initialized as "0.0" when defect calculations are imported. Userdefined energy corrections can be imported separately (see Section 2.2). Lastly, the DOS_Tracker.json file is simply organized into key-value pairs of the energy and corresponding DOS, as shown in the bottom right column of Figure .
