Contents are discussed next.</p> <p>- splits: The data splits used in the published paper. Each file "splits_X.json"</p> <p>contains the splits for training size X.</p> <p><br></p> <p>The "runs" directory contains one directory for each run, named with the index</p> <p>of the run. Each directory contains:</p> <p>- RUN.fdf, geom.fdf: The input files used for the SIESTA calculation.</p> <p>- RUN.out: The log of the SIESTA run, which apar</p> <p>- siesta.TSDE: Contains the Density and Energy Density matrices.</p> <p>- siesta.TSHS: Contains the Hamiltonian and Overlap matrices.</p> <p><br></p> <p>Each matrix can be read using the sisl python package (https://github.com/zerothi/sisl)</p> <p>like:</p> <p><br></p> <p>```python</p> <p>import sisl</p> <p><br></p> <p>matrix = sisl.get_sile("RUN.fdf").read_X()</p> <p>```</p> <p><br></p> <p>where X is hamiltonian, overlap, density_matrix or energy_density_matrix.</p> <p><br></p> <p>To reproduce the results presented in the paper, follow the documentation of the graph2mat</p> <p>package (https://github.com/BIG-MAP/graph2mat).</p> <p><br></p> <p><br></p> <p>Cite this data</p> <p>------------------</p> <p>https://doi.org/10.11583/DTU.c.7310005</p> <p>© 2024 Technical University of Denmark</p> <p><br></p> <p><br></p> <p>License</p> <p>-----------------</p> <p>This dataset is published under the CC BY 4.0 license.</p> <p>This license allows reusers to distribute, remix, adapt, and build upon the material in any medium or format, so long as attribution is given to the creator.</p> <p><br></p>
