RuntimeError: nbits=1 not supported

Hello, when i run your tutorial about "Candidate class to analyse single pulses".
i have the problem below:
Traceback (most recent call last):

Could you help me what's the problem i have encountered.

As mentioned in the error, nbits=1 is not supported. If you can contribute to the package and send a PR, we will happily incorporate it.

One trick would do would be to add np.bool_ for nbits=1 here:

your/your/formats/pysigproc.py

Lines 244 to 251 in e342da8

	if self.nbits == 8:
	return numpy.uint8
	elif self.nbits == 16:
	return numpy.uint16
	elif self.nbits == 32:
	return numpy.float32
	else:
	raise RuntimeError("nbits=%d not supported" % self.nbits)

@mabaisen, can you share a sample 1-bit filterbank?

[mabaisen]

Thank you for your help. I download the filterbank from "https://data-portal.hpc.swin.edu.au/dataset/parkes-frbs-archival-data".
I used the first filterbank in FRB010125.tar.gz run your_candmaker
