Hello Dominik,
Recently I try to learn z2pack. I used it to calculate the Z2 invariants of Bi and Bi2Se3 and found it's really a very good tool! Then I want to apply it to calculate the chirality of wey points using vasp. But after I use it , it encountered a problem:
“File "/home/qian/.local/lib/python3.6/site-packages/z2pack/fp/kpoint.py", line 189, in _check_equal_spacing raise ValueError('The k-points must be equally spaced for {} runs.'.format(run_type)) ValueError: The k-points must be equally spaced for VASP runs.”
How can I solve this problem ? Does that mean z2pack can 't calculate the chirality using vasp?
Looking forward to your reply ! Thank you in advance.
Best regards, Yuting Qian
