    Calculating Tajima's D from SNP frequency data

    Hi,

    I have recently run some forward simulations that produce a table with with the major allele frequency for every SNP along single chromosome in my simulations populations. The table looks something like:

    Code:
    chr	pos	ref	pop1	pop2	pop3
    3R	56	A	0.833	0.902	0.523
    3R	89	C	0.711	0.622	0.623
    ...
    I was primarily interested in doing some heterzygosity calculations and Fst estimations to compare to results from my real data set, which was straight forward enough. However, if possible, I would also like to do Tajima's D calculations across 50kb windows from this simulated data set. Apologize if this is actually something really simple, but not quite sure how to do this with just SNP frequencies based on what I have read on how to do this calculation.

    Multiomic Liquid Biopsy: What DNA/RNA Panels Reveal That DNA Alone Can’t
    by SEQadmin2



    Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?

    Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating

    New Genomics Technologies Take Aim at Long-Standing Limits
    by SEQadmin2


    Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.

    We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing
