negative dimensions are not allowed

I am trying to implement DeepMRAC for T1 and UTE worked fine. For Dixon for the same patient I am getting the following error:

Found files in /home/xxxxxx/Desktop/Claes/data/Dixon/Umap
Traceback (most recent call last):
File "process_DeepDixon_dicom.py", line 253, in
convert_data()
File "process_DeepDixon_dicom.py", line 71, in convert_data
assert len(os.listdir('%s/%s' % (tmpdir, datasets[2]))) == 132
IndexError: list index out of range

I changed the 132 to 128 in line 71 of the process_DeepDixon_dicom.py script:
assert len(os.listdir('%s/%s' % (tmpdir, datasets[2]))) == 132
since my Umap had 128 images and i have getting an error:

After this change i got the following error:
