Just posted: a group paper describing major updates to my software pixy, for population genetic summary statistics. www.biorxiv.org/content/10.6... New since 2021: arbitrary ploidy, multiallelic sites, missingness-aware Watterson's θ and Tajima's D, Hudson's FST, multicore execution!
Alt text: Schematic of the pixy workflow. Left, inputs: a bgzipped, tabix- or CSI-indexed VCF with callable sites supplied as an all-sites VCF or gVCF blocks, a populations file, and optional BED and sites files. Centre, core: windowing by fixed width, BED or region; statistic selection; options for Hudson's FST, multiallelic SNPs, automatic ploidy detection and multicore execution. Right, outputs: one TSV per statistic for pi, dxy, FST, Watterson's theta and Tajima's D, with raw count columns for exact aggregation. Bottom, development: GitHub fork and pull request, local checks with ruff, mypy and pytest, continuous integration across Python 3.10 to 3.14, and distribution through conda-forge. Features new since the 2021 release are badged "new".
