The dataset is published as part of the paper:
"GRAPH2MAT: UNIVERSAL GRAPH TO MATRIX CONVERSION FOR ELECTRON DENSITY PREDICTION"
(https://doi.org/10.26434/chemrxiv-2024-j4g21)
Short description
------------------
This dataset contains the Hamiltonian, Overlap, Density and Energy Density matrices
from SIESTA calculations of the QM9 dataset (https://doi.org/10.6084/m9.figshare.c.978904.v5)
SIESTA 5.0.0 was used to compute the dataset.
Contents
-----------------
The dataset has four directories:
- basis: Contains the files specifying the basis used for each atom.
- pseudos: Contains the pseudopotentials used for the calculation (obtained from
http://www.pseudo-dojo.org/, type NC SR (ONCVPSP v0.5), PBE, standard accuracy)
- runs: The results of running the SIESTA simulations. Contents are discussed next.
- splits: The data splits used in the published paper. Each file "splits_X.json"
contains the splits for training size X.
The "runs" directory contains one directory for each run, named with the index
of the run. Each directory contains:
- RUN.fdf, geom.fdf: The input files used for the SIESTA calculation.
- RUN.out: The log of the SIESTA run, which apar
- siesta.TSDE: Contains the Density and Energy Density matrices.
- siesta.TSHS: Contains the Hamiltonian and Overlap matrices.
Each matrix can be read using the sisl python package (https://github.com/zerothi/sisl)
like:
```python
import sisl
matrix = sisl.get_sile("RUN.fdf").read_X()
```
where X is hamiltonian, overlap, density_matrix or energy_density_matrix.
