Install aflow from the python package index:

pip install aflow

Or alternatively install aflow from conda using:

conda install -c conda-forge aflow

Open an ipython notebook or terminal and execute the query from the paper:

from aflow import *

result = search(batch_size=20
        ).filter(K.Egap > 6).orderby(K.agl_thermal_conductivity_300K, True)

# Now, you can just iterate over the results.
for entry in result:

aflow supports lazy evaluation. This means that if you didn’t ask for a particular property during the initial query, you can just ask for it later and the request will happen transparently in the background.

Python 2 Support

Although the package was originally designed to be compatible with both python 2 and python 3, python 2 has reached the end of its life. As such, we don’t guarantee anymore that it will work.
