1. New compounds info should be put in the newCompound.xlsx file, with the specified format as described in the excel file
2. The training data should be put in the perovskite_DFT_EaH_FormE.xlsx. This file already contains over 1900 compounds. Users can add more compounds to this training set.
3. Run python script energy_prediction.py using command: python energy_prediction.py. Requirements:

• python version >= 3.5

• sklearn, pandas, numpy.

4. During the running of the python script, temporary files *.csv will be generated, which contain the generated features of the compounds in the training set and the new compounds to be predicted. The temporary files are generated by feature_vector.py, called by the energy_prediction.py.
5. Results are put in the prediction_result.xlsx file. In the stability column, 1 stands for stable, 0 stands for unstable.

The energy_prediction embeds the selected best classification model (extra trees) and the best regression model (kernel ridge regression).

The elemental property database is provided as continousproperty.xlsx, discrictproperty.xlsx and shannon_perovskite.xlsx. Feature inportance list is stored by *.txt files.
