Segmentation fault (core dumped)

I am currently going through the MiXeR tutorial, which I plan to implement in my current study.

When I ran the python mixer.py ld and python mixer.py snp codes to generate.ld and.snp files, I kept on getting "segmentation fault (core dump)". I am new to statistical genetics studies, and I am not very good at writing codes or interpreting codes appropriately.

I would appreciate it if anyone on this platform could help me resolve this. It is putting a stop to my progress in my research;

Below are the scripts and the output for scrutiny and possible solutions.

Hi @olasunkanmibamidele. This could be a duplicate of #48.

Also, issues with the /build/lib/libbgmg.so extension may be solved by the container build at https://github.com/comorment/mixer. But you need a machine/HPC resource with Apptainer alternatively Singularity, or Docker. The latter may use these images but I've yet to write proper documentation for it (but should work on M1/M2 Macs with the platform=linux/amd64 option)
