Error using cat Dimensions of arrays being concatenated are not consistent- Radiomics package

I have been trying to run Radiomics package( https://uk.mathworks.com/matlabcentral/fileexchange/51948-radiomics )on a dataset from the cancer imaging archive.( https://wiki.cancerimagingarchive.net/display/Public/HNSCC#41518000036220c66a5a436f90e4a0b54367bfae,) but it throws error as below. I am in the process of making the code work on this dataset(selected only first five image data from the archive- (HNSCC-01-0001 to HNSCC-01-0005), but as cell2mat is not editable, I am not sure how to make changes so that it works fine.

Any suggestions would be appreciated.

Thanks

Did you ask the author of this tool already?

The author of this package confirmed that the code would work with any dataset with RTSTRUCT available. That inspired me to try this code on this new dataset other than the one which the author originally wrote this code for.(https://wiki.cancerimagingarchive.net/display/Public/Head-Neck-PET-CT)
