Right now I am running HISAT2 on the Homo sapiens hg38 SNP db from which will produce 88 individual *.sam files (I have 88 samples) that I will then use to create vcf files.

Anyways, I want to get these vcf files into a form that I can use for some of my downstream pipelines. My question, is how can I get these vcf files into a (n= samples, m= SNPs) dimensional data matrix (preferably in Python or vcftools but open to others or writing my own method)? I have seen the term genotyping matrix in my Google searches, is this what I am trying to create? Apologies if this question is naive. I planned to create my own using pandas in Python but did not want to recreate the wheel if one already exists.

I'm using Python 3.6.1 on OSX.
