Error running Shorah.py, and seeking for help

[JingniHe]

Hi, recently, I tried to use your tool " ShoRAH" to generate global reconstruction haplotypes, but I ran into some problems.

So I try to run the tool on Linux by using the command “./shorah.py -b sorted.bam -f ref.fa -w 48”. I generated the sorted bam file using BWA and SAMTOOLS, and the length of my read is 100.

At beginning, it would generate lots of files like this:

But then, it would run into an error showed as following:

It seems like something wrong with the codes, but I don't know how to fix this.

I sincerely hope for you suggestions and help. Thank you very much, and have a good day!
