reweighting error

I have been running this function with the correct paramters
reweight_object.run(gamma=basegamma, data_folders=folders, kint_file=rates, exp_file=expt, times=times, restart_interval=100, out_prefix=f'reweighting_gamma_1x10^{exponent}_')_
and I keep getting this error.
Traceback (most recent call last):

ValueError: all input arrays must have the same shape

During handling of the above exception, another exception occurred:

ValueError: Error in stacking files read with np.loadtxt - are they all the same length?

I checked the files and they all are of the same length.

Reproduce the call to reweight_object.run and trace into HDXer/reweighting.py: setup_no_runobj, then HDXer/reweighting_functions.py: read_contacts_hbonds and files_to_array. Inspect the arrays loaded from the contact files and compare their shapes and lengths. Done means identifying why the reported inputs cannot be stacked or improving the error handling so the cause is clear.
