SequenceContainer.py fails with missing attribute in Seq object

[Npaffen]

Describe the bug A clear and concise description of what the bug is.

When I try to run gen_reads.py with a custom vcf for the variants to add to output some golden bam with a reduced coverage the pipeline breaks after reading the vcf.

My pipeline looks like this.

call = glue("python3 neat-genreads-master/gen_reads.py -r {reference} -R 150 -o data/1kg_hg37/bam/sample1/ --bam -v data/1kg_hg37/sample_1_chr.vcf -c 0.04")
system(call)

Please check that your version of biopython is the most recent. That error usually pops up because of an older version of biopython.

I have the most recent biopython version installed. See :

Actually, so what I would recommend is instead of this repo, which is no longer maintained, you check out our newest work on github.com/ncsa/NEAT. If you want to maintain the same functionality as this version, then checkout the latest release of version 3. Otherwise, you can also try version 4, which is different. I believe we've resolved this bug in that more up-to-date repo.

Unless biopython overhauled their mutable sequence code again, in which case I'll have to do some more investigation. Try using the latest and post a bug on that page if it still isn't working. Thanks!
