MesoscopePreprocess task errors when exptQC.mat contains empty cell

[k1o0]

These mesoscope preprocess tasks are failing because of something to do with the exptQC.mat file. Here's an example of a problem file: /mnt/s0/Data/Subjects/SP058/2024-08-20/001/raw_imaging_data_02/exptQC.mat. For some reason the last element is loaded as an empty array which causes problems.

When loaded in python they look like this:
Normal:
array(['ok', 'PMT off', 'galvos fault', 'high signal'], dtype=object)
Problem file:
array(['ok', 'PMT off', 'galvos fault', 'high signal', array([], dtype='<U1')], dtype=object)
