WebFor this, we will use bcftools, a set of tools to call variants and manipulate them. We will run two commands, bcftools mpileup, which looks for inconsistencies between the reference and the aligned reads, and bcftools call, which interprets them as variants. WebJul 7, 2024 · The hs37d5 reference is recommended for optimal read mapping for variant calling, and is therefore suitable for exome and whole-genome sequencing data.
