LoadError: UndefVarError: spones not defined

[ShallyLai]

Hello,
This package is really helpful to my research.

I also try to use Julia and Python versions of reproducibility calculation, and both of them need to be modified for work.

Python version can run successfully when adding max_index = int(max_index) in both Parse_matrix_lieberman and Parse_matrix_hic functions.

But Julia script still appears LoadError: UndefVarError: spones not defined, and I'm not sure how to fix it.
This occurs when I try to use the sample files in data.

julia run_reproducibility.jl data/examples_hicpro/reads_500000_1.matrix data/examples_hicpro/reads_500000_2.matrix

I am a newbie of Julia. Do I forget to import any packages??

Julia version: 1.7 (The latest).

Hope for your reply.

Thank you
