Quickstart

Install aflow from the python package index:

pip install aflow

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

from aflow import *

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

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

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.
