Unbiased estimation of nucleotide diversity within and between populations
copied from cf-staging / pixypixy is a command-line tool for painlessly and correctly estimating average nucleotide diversity within (π) and between (dxy) populations from a VCF. In particular, pixy facilitates the use of VCFs containing invariant (AKA monomorphic) sites, which are essential for the correct computation of π and dxy.
