There is an error in api_unfolding.py

[373Kice]

upho-0.6.1-py3.7.egg/upho/api_unfolding.py", line 52, in init
NameError: name 'primitive_matrix' is not defined

when I run upho_weights band.conf, it return an NameError;

elif primitive_matrix is not None:
            self._primitive_matrix_ideal = np.array(primitive_matrix_ideal,
                                              dtype='double', order='c')

in line 52, does the primitive_matrix means primitive_matrix_ideal ?
After I change primitive_matrix to primitive_matrix_ideal, it can work.

Thank you for trying the code as well as the issue. Unfortunately, without details of your calculations, I cannot provide you concrete advices. Maybe you can first check if you correctly have "PRIMITIVE_AXIS" tag in your band.conf. Changing the code and working does NOT immediately mean we do the correct thing.

Dear all,
I also face such error.
I am doing calculation on a distorted structure with body centered orthorhombic crystal (space group i4/mcm , # 140) and I want to unfold the phonon band of this structure on to the main cubic structure (with space group # 221) .
I would be thankful for any help in advance.
This is the exact error :
