Attribute Error in readligo.py

1

In readligo.py:
line 125 shortnameArray =dqInfo['DQShortnames'].value

I am getting error: ‘Dataset’ object has no attribute ‘value’
Could anyone resolve this query? Thanks!

Because the dataset.value attribute was deprecated (ref: stackoverflow), you can use dataset[()] instead of dataset.value.

# shortnameArray = dqInfo[‘DQShortnames’].value
shortnameArray = dqInfo[‘DQShortnames’][()]

OP: Notice that readligo is no longer maintained, if you want to read and write GW data files or doing any analysis, I recommend you learn using GWpy, that is actively maintained and patched.
