Dear @rosenbrockc and @wsmorgan,
I want to search for structures that only contains Cu. I tried to use the code below. But, it returns me compound, i.e. Cu4Mg1Y1.
results = search(batch_size = 100
).filter(K.species == 'Cu')
I really appreciate for your help!
Hi,
I recently build the conda-forge package for aflow, you can now install it using:
conda install -c conda-forge aflow
Best,
Jan
After installing the aflow package and trying to use the standard query example given in the documentation, I am encountering following error. Is there a bug in the code?
In [2]: 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)
...:
ERROR: http://aflowlib.duke.edu/search/API/?agl_thermal_conductivity_300K,Egap(6*),paging(-1,20)

TypeError: '<' not supported between instances of 'int' and 'NoneType'
result = search(batch_size=50
).select(K.species=="Al,Co,W"
).select(K.stoichiometry % "0.75")
is evidently not a valid query because there is not JSON response:
ValueError: No JSON object could be decoded
But, instead of failing gracefully, it chokes.
Add to https://github.com/rosenbrockc/aflow/blob/master/aflow/entries.py#L11
if value is None:
return
so that keywords with None
values don't cause exceptions.
Compressed file formats and image files were throwing decoding errors.
A fix has been implemented by Wiley Morgan and the files are downloading properly and as expected. Wiley has the new code, and will shortly submit a push request.
